Trusting all certificates using HttpClient over HTTPS
Recently posted a question regarding the HttpClient over Https (found here). I've made some headway, but I've run into new issues. As with my last problem, I can't seem to find an example anywhere that works for me. Basically, I want my client to accept any certificate (because I'm only ever pointing to one server) but I keep getting a javax.net.ssl.SSLException: Not trusted server certificate exception.
So this is what I have:
public void connect() throws A_WHOLE_BUNCH_OF_EXCEPTIONS {
HttpPost post = new HttpPost(new URI(PROD_URL));
post.setEntity(new StringEntity(BODY));
KeyStore trusted = KeyStore.getInstance("BKS");
trusted.load(null, "".toCharArray());
SSLSocketFactory sslf = new SSLSocketFactory(trusted);
sslf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme ("https", sslf, 443));
SingleClientConnManager cm = new SingleClientConnManager(post.getParams(),
schemeRegistry);
HttpClient client = new DefaultHttpClient(cm, post.getParams());
HttpResponse result = client.execute(post);
}
And here's the error I'm getting:
W/System.err( 901): javax.net.ssl.SSLException: Not trusted server certificate

You basically have four potential solutions to fix a "Not Trusted" exception on Android using httpclient:
- Trust all certificates. Don't do this, unless you really know what you're doing.
- Create a custom SSLSocketFactory that trusts only your certificate. This works as long as you know exactly which servers you're going to connect to, but as soon as you need to connect to a new server with a different SSL certificate, you'll need to update your app.
- Create a keystore file that contains Android's "master list" of certificates, then add your own. If any of those certs expire down the road, you are responsible for updating them in your app. I can't think of a reason to do this.
- Create a custom SSLSocketFactory that uses the built-in certificate KeyStore, but falls back on an alternate KeyStore for anything that fails to verify with the default.
This answer uses solution #4, which seems to me to be the most robust.
The solution is to use an SSLSocketFactory that can accept multiple KeyStores, allowing you to supply your own KeyStore with your own certificates. This allows you to load additional top-level certificates such as Thawte that might be missing on some Android devices. It also allows you to load your own self-signed certificates as well. It will use the built-in default device certificates first, and fall back on your additional certificates only as necessary.
First, you'll want to determine which cert you are missing in your KeyStore. Run the following command:
openssl s_client -connect www.yourserver.com:443
And you'll see output like the following:
Certificate chain
0 s:/O=www.yourserver.com/OU=Go to
https://www.thawte.com/repository/index.html/OU=Thawte SSL123
certificate/OU=Domain Validated/CN=www.yourserver.com
i:/C=US/O=Thawte, Inc./OU=Domain Validated SSL/CN=Thawte DV SSL CA
1 s:/C=US/O=Thawte, Inc./OU=Domain Validated SSL/CN=Thawte DV SSL CA
i:/C=US/O=thawte, Inc./OU=Certification Services Division/OU=(c)
2006 thawte, Inc. - For authorized use only/CN=thawte Primary Root CA
As you can see, our root certificate is from Thawte. Go to your provider's website and find the corresponding certificate. For us, it was here, and you can see that the one we needed was the one Copyright 2006.
If you're using a self-signed certificate, you didn't need to do the previous step since you already have your signing certificate.
Then, create a keystore file containing the missing signing certificate. Crazybob has details how to do this on Android, but the idea is to do the following:
If you don't have it already, download the bouncy castle provider library from: http://www.bouncycastle.org/latest_releases.html. This will go on your classpath below.
Run a command to extract the certificate from the server and create a pem file. In this case, mycert.pem.
echo | openssl s_client -connect ${MY_SERVER}:443 2>&1 | \
sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > mycert.pem
Then run the following commands to create the keystore.
export CLASSPATH=/path/to/bouncycastle/bcprov-jdk15on-155.jar
CERTSTORE=res/raw/mystore.bks
if [ -a $CERTSTORE ]; then
rm $CERTSTORE || exit 1
fi
keytool \
-import \
-v \
-trustcacerts \
-alias 0 \
-file <(openssl x509 -in mycert.pem) \
-keystore $CERTSTORE \
-storetype BKS \
-provider org.bouncycastle.jce.provider.BouncyCastleProvider \
-providerpath /path/to/bouncycastle/bcprov-jdk15on-155.jar \
-storepass some-password
You'll notice that the above script places the result in res/raw/mystore.bks. Now you have a file that you'll load into your Android app that provides the missing certificate(s).
To do this, register your SSLSocketFactory for the SSL scheme:
final SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
schemeRegistry.register(new Scheme("https", createAdditionalCertsSSLSocketFactory(), 443));
// and then however you create your connection manager, I use ThreadSafeClientConnManager
final HttpParams params = new BasicHttpParams();
...
final ThreadSafeClientConnManager cm = new ThreadSafeClientConnManager(params,schemeRegistry);
To create your SSLSocketFactory:
protected org.apache.http.conn.ssl.SSLSocketFactory createAdditionalCertsSSLSocketFactory() {
try {
final KeyStore ks = KeyStore.getInstance("BKS");
// the bks file we generated above
final InputStream in = context.getResources().openRawResource( R.raw.mystore);
try {
// don't forget to put the password used above in strings.xml/mystore_password
ks.load(in, context.getString( R.string.mystore_password ).toCharArray());
} finally {
in.close();
}
return new AdditionalKeyStoresSSLSocketFactory(ks);
} catch( Exception e ) {
throw new RuntimeException(e);
}
}
And finally, the AdditionalKeyStoresSSLSocketFactory code, which accepts your new KeyStore and checks if the built-in KeyStore fails to validate an SSL certificate:
/**
* Allows you to trust certificates from additional KeyStores in addition to
* the default KeyStore
*/
public class AdditionalKeyStoresSSLSocketFactory extends SSLSocketFactory {

return list.toArray(new X509Certificate[list.size()]);
}
}
}
Note: Do not implement this in production code you are ever going to use on a network you do not entirely trust. Especially anything going over the public internet.
Your question is just what I want to know. After I did some searches, the conclusion is as follows.
In HttpClient way, you should create a custom class from org.apache.http.conn.ssl.SSLSocketFactory, not the one org.apache.http.conn.ssl.SSLSocketFactory itself. Some clues can be found in this post Custom SSL handling stopped working on Android 2.2 FroYo.
An example is like ...
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import org.apache.http.conn.ssl.SSLSocketFactory;
public class MySSLSocketFactory extends SSLSocketFactory {
SSLContext sslContext = SSLContext.getInstance("TLS");
public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
super(truststore);
TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
sslContext.init(null, new TrustManager[] { tm }, null);
}
@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
}
@Override
public Socket createSocket() throws IOException {
return sslContext.getSocketFactory().createSocket();
}
}
and use this class while creating instance of HttpClient.
public HttpClient getNewHttpClient() {
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);
MySSLSocketFactory sf = new MySSLSocketFactory(trustStore);
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
return new DefaultHttpClient(ccm, params);
} catch (Exception e) {
return new DefaultHttpClient();
}
}
BTW, the link below is for someone who is looking for HttpURLConnection solution. Https Connection Android
I have tested the above two kinds of solutions on froyo, and they all work like a charm in my cases. Finally, using HttpURLConnection may face the redirect problems, but this is beyond the topic.
Note: Before you decide to trust all certificates, you probably should know the site full well and won't be harmful of it to end-user.
Indeed, the risk you take should be considered carefully, including the effect of hacker's mock site mentioned in the following comments that I deeply appreciated. In some situation, although it might be hard to take care of all certificates, you'd better know the implicit drawbacks to trust all of them.
Add this code before the HttpsURLConnection and it will be done. I got it.
private void trustEveryone() {
try {
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier(){
public boolean verify(String hostname, SSLSession session) {
return true;
}});
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, new X509TrustManager[]{new X509TrustManager(){
public void checkClientTrusted(X509Certificate[] chain,
String authType) throws CertificateException {}
public void checkServerTrusted(X509Certificate[] chain,
String authType) throws CertificateException {}
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}}}, new SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(
context.getSocketFactory());
} catch (Exception e) { // should never happen
e.printStackTrace();
}
}
This is a bad idea. Trusting any certificate is only (very) slightly better than using no SSL at all. When you say "I want my client to accept any certificate (because I'm only ever pointing to one server)" you are assuming this means that somehow pointing to "one server" is safe, which it's not on a public network.
You are completely open to a man-in-the-middle attack by trusting any certificate. Anyone can proxy your connection by establishing a separate SSL connection with you and with the end server. The MITM then has access to your entire request and response. Unless you didn't really need SSL in the first place (your message has nothing sensitive, and doesn't do authentication) you shouldn't trust all certificates blindly.
You should consider adding the public cert to a jks using keytool, and using that to build your socket factory, such as this:
KeyStore ks = KeyStore.getInstance("JKS");
// get user password and file input stream
char[] password = ("mykspassword")).toCharArray();
ClassLoader cl = this.getClass().getClassLoader();
InputStream stream = cl.getResourceAsStream("myjks.jks");
ks.load(stream, password);
stream.close();
SSLContext sc = SSLContext.getInstance("TLS");
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
kmf.init(ks, password);
tmf.init(ks);
sc.init(kmf.getKeyManagers(), tmf.getTrustManagers(),null);
return sc.getSocketFactory();
This has one caveat to watch out for. The certificate will expire eventually, and the code will stop working at that time. You can easily determine when this will happen by looking at the cert.
You can disable HttpURLConnection SSL checking for testing purposes this way since API 8:
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
if (conn instanceof HttpsURLConnection) {
HttpsURLConnection httpsConn = (HttpsURLConnection) conn;
httpsConn.setSSLSocketFactory(SSLCertificateSocketFactory.getInsecure(0, null));
httpsConn.setHostnameVerifier(new AllowAllHostnameVerifier());
}
The code above in https://stackoverflow.com/a/6378872/1553004 is correct, except it MUST also call the hostname verifier:
@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException {
SSLSocket sslSocket = (SSLSocket)sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
getHostnameVerifier().verify(host, sslSocket);
return sslSocket;
}
I signed up to stackoverflow expressly to add this fix. Heed my warning!
The API of HttpComponents has got changed. It works with the code below.
public static HttpClient getTestHttpClient() {
try {
SSLSocketFactory sf = new SSLSocketFactory(new TrustStrategy(){
@Override
public boolean isTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
return true;
}
}, new AllowAllHostnameVerifier());
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("https",8444, sf));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(registry);
return new DefaultHttpClient(ccm);
} catch (Exception e) {
e.printStackTrace();
return new DefaultHttpClient();
}
}
I'm adding a response for those that use the httpclient-4.5, and probably works for 4.4 as well.
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import org.apache.http.HttpResponse;

builder.loadTrustMaterial(null, new TrustStrategy() {

return true;
}
});
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(builder.build(), new NoopHostnameVerifier());
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build();
return httpclient;
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
Trusting all certificates was no real alternative for me, so I did the following to get HttpsURLConnection to trust a new certificate (see also http://nelenkov.blogspot.jp/2011/12/using-custom-certificate-trust-store-on.html).
Get the certificate; I got this done by exporting the certificate in Firefox (click on the little lock icon, get certificate details, click export), then used portecle to export a truststore (BKS).
Load the Truststore from /res/raw/geotrust_cert.bks with the following code:
final KeyStore trustStore = KeyStore.getInstance("BKS"); final InputStream in = context.getResources().openRawResource( R.raw.geotrust_cert); trustStore.load(in, null); final TrustManagerFactory tmf = TrustManagerFactory .getInstance(TrustManagerFactory.getDefaultAlgorithm()); tmf.init(trustStore); final SSLContext sslCtx = SSLContext.getInstance("TLS"); sslCtx.init(null, tmf.getTrustManagers(), new java.security.SecureRandom()); HttpsURLConnection.setDefaultSSLSocketFactory(sslCtx .getSocketFactory());
Here is a much simple version using 4.1.2 httpclient code. This can then be modified to any trust algorithm you see fit.
public static HttpClient getTestHttpClient() {
try {
SSLSocketFactory sf = new SSLSocketFactory(new TrustStrategy(){
@Override
public boolean isTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
return true;
}
});
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("https", 443, sf));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(registry);
return new DefaultHttpClient(ccm);
} catch (Exception e) {
return new DefaultHttpClient();
}
}
I'm looked response from "emmby" (answered Jun 16 '11 at 21:29), item #4: "Create a custom SSLSocketFactory that uses the built-in certificate KeyStore, but falls back on an alternate KeyStore for anything that fails to verify with the default."
This is a simplified implementation. Load the system keystore & merge with application keystore.
public HttpClient getNewHttpClient() {
try {
InputStream in = null;
// Load default system keystore
KeyStore trusted = KeyStore.getInstance(KeyStore.getDefaultType());
try {
in = new BufferedInputStream(new FileInputStream(System.getProperty("javax.net.ssl.trustStore"))); // Normally: "/system/etc/security/cacerts.bks"
trusted.load(in, null); // no password is "changeit"
} finally {
if (in != null) {
in.close();
in = null;
}
}
// Load application keystore & merge with system
try {
KeyStore appTrusted = KeyStore.getInstance("BKS");
in = context.getResources().openRawResource(R.raw.mykeystore);
appTrusted.load(in, null); // no password is "changeit"
for (Enumeration<String> e = appTrusted.aliases(); e.hasMoreElements();) {
final String alias = e.nextElement();
final KeyStore.Entry entry = appTrusted.getEntry(alias, null);
trusted.setEntry(System.currentTimeMillis() + ":" + alias, entry, null);
}
} finally {
if (in != null) {
in.close();
in = null;
}
}
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SSLSocketFactory sf = new SSLSocketFactory(trusted);
sf.setHostnameVerifier(SSLSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
return new DefaultHttpClient(ccm, params);
} catch (Exception e) {
return new DefaultHttpClient();
}
}
A simple mode to convert from JKS to BKS:
keytool -importkeystore -destkeystore cacerts.bks -deststoretype BKS -providerclass org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath bcprov-jdk16-141.jar -deststorepass changeit -srcstorepass changeit -srckeystore $JAVA_HOME/jre/lib/security/cacerts -srcstoretype JKS -noprompt
*Note: In Android 4.0 (ICS) the Trust Store has changed, more info: http://nelenkov.blogspot.com.es/2011/12/ics-trust-store-implementation.html
For those who would like to allow all certificates to work (for testing purposes) over OAuth, follow these steps:
1) Download the source code of the Android OAuth API here: https://github.com/kaeppler/signpost
2) Find the file "CommonsHttpOAuthProvider" class
3) Change it as below:
public class CommonsHttpOAuthProvider extends AbstractOAuthProvider {
private static final long serialVersionUID = 1L;
private transient HttpClient httpClient;
public CommonsHttpOAuthProvider(String requestTokenEndpointUrl, String accessTokenEndpointUrl,
String authorizationWebsiteUrl) {
super(requestTokenEndpointUrl, accessTokenEndpointUrl, authorizationWebsiteUrl);
//this.httpClient = new DefaultHttpClient();//Version implemented and that throws the famous "javax.net.ssl.SSLException: Not trusted server certificate" if the certificate is not signed with a CA
this.httpClient = MySSLSocketFactory.getNewHttpClient();//This will work with all certificates (for testing purposes only)
}
The "MySSLSocketFactory" above is based on the accepted answer. To make it even easier, here goes the complete class:

I used this and It works for me on all OS.

There are a-lot alternatives for this use case. If you don't want to have any custom code in your code base such as custom TrustManager or custom SSLSocketFactory I would suggest to try GitHub - SSLContext Kickstart and the following code snippet:
<dependency>
<groupId>io.github.hakky54</groupId>
<artifactId>sslcontext-kickstart</artifactId>
<version>7.0.2</version>
</dependency>
SSL configuration
SSLFactory sslFactory = SSLFactory.builder()
.withUnsafeTrustMaterial()
.withUnsafeHostnameVerifier()
.build();
SSLSocketFactory sslSocketFactory = sslFactory.getSslSocketFactory();
HttpClient configuration
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("https", sslSocketFactory, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
HttpClient httpClient = new DefaultHttpClient(ccm, params);
HttpsUrlConnection
HttpsURLConnection.setDefaultSSLSocketFactory(sslSocketFactory);
I also need to give some disclaimer, I am the maintainer of the library.
Just adding -Dtrust_all_cert=true to VM arguments should do. This argument tells java to ignore certificate checks.
Any body still struggling with StartCom SSL Certificates on Android 2.1 visit https://www.startssl.com/certs/ and download the ca.pem, now in the answer provided by @emmby replace
`export CLASSPATH=bcprov-jdk16-145.jar
CERTSTORE=res/raw/mystore.bks
if [ -a $CERTSTORE ]; then
rm $CERTSTORE || exit 1
fi
keytool \
-import \
-v \
-trustcacerts \
-alias 0 \
-file <(openssl x509 -in mycert.pem) \
-keystore $CERTSTORE \
-storetype BKS \
-provider org.bouncycastle.jce.provider.BouncyCastleProvider \
-providerpath /usr/share/java/bcprov.jar \
-storepass some-password`
with
`export CLASSPATH=bcprov-jdk16-145.jar
CERTSTORE=res/raw/mystore.bks
if [ -a $CERTSTORE ]; then
rm $CERTSTORE || exit 1
fi
keytool \
-import \
-v \
-trustcacerts \
-alias 0 \
-file <(openssl x509 -in ca.pem) \
-keystore $CERTSTORE \
-storetype BKS \
-provider org.bouncycastle.jce.provider.BouncyCastleProvider \
-providerpath /usr/share/java/bcprov.jar \
-storepass some-password`
Should work out of the box. I was struggling it for over a day even after a perfect answer by @emmby.. Hope this helps someone...

A sspi failed in xamarin android.
I found this solution; put this code before you hit on an HTTPS link
const SslProtocols _Tls12 = (SslProtocols)0x00000C00;
const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;
ServicePointManager.SecurityProtocol = Tls12;
work with all https
httpClient = new DefaultHttpClient();
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException { }
public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException { }
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
httpClient.getConnectionManager().getSchemeRegistry().register(new Scheme("https", 443, ssf));
There a many answers above but I wasn't able to get any of them working correctly (with my limited time), so for anyone else in the same situation you can try the code below which worked perfectly for my java testing purposes:
public static HttpClient wrapClient(HttpClient base) {
try {
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException { }
public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException { }
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx);
ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", ssf, 443));
return new DefaultHttpClient(ccm, base.getParams());
} catch (Exception ex) {
return null;
}
}
and call like:
DefaultHttpClient baseClient = new DefaultHttpClient();
HttpClient httpClient = wrapClient(baseClient );
Reference: http://tech.chitgoks.com/2011/04/24/how-to-avoid-javax-net-ssl-sslpeerunverifiedexception-peer-not-authenticated-problem-using-apache-httpclient/
Simply use this -
public DefaultHttpClient wrapClient(HttpClient base) {
try {
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException { }
public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException { }
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx);
ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = base.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", ssf, 443));
return new DefaultHttpClient(ccm, base.getParams());
} catch (Exception ex) {
return null;
}
}
Daniel's answer was good except I had to change this code...
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
to this code...
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
SchemeRegistry registry = ccm.getShemeRegistry()
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
to get it to work.
加载中,请稍侯......
