Android: Making Https Request
How do I avoid the "javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated" exception and the Android Apache lib gap "开发者_JAVA技巧The constructor SSLSocketFactory(SSLContext) is undefined" in making an Https request?
This method takes an HttpClient instance and returns a ready-for-https HttpClient instance.
private HttpClient sslClient(HttpClient client) {
try {
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;
}
};
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new MySSLSocketFactory(ctx);
ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager ccm = client.getConnectionManager();
SchemeRegistry sr = ccm.getSchemeRegistry();
sr.register(new Scheme("https", ssf, 443));
return new DefaultHttpClient(ccm, client.getParams());
} catch (Exception ex) {
return null;
}
}
Because the Android org.apache.http.conn.ssl.SSLSocketFactory does not have the SSLSocketFactory(SSLContext) constructor, I have extended the class as follows.
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);
}
public MySSLSocketFactory(SSLContext context) throws KeyManagementException, NoSuchAlgorithmException, KeyStoreException, UnrecoverableKeyException {
super(null);
sslContext = context;
}
@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();
}
}
Excellent article here: http://javaskeleton.blogspot.com/2010/07/avoiding-peer-not-authenticated-with.html
And some help here: Trusting all certificates using HttpClient over HTTPS
I had similar problem which is more like this question but the root cause was completely different from those mentioned in both questions.
I was using DefaultHttpClient as httpclient for requesting https://maps.googleapis.com like links. I was trying whole banch of proposed solutions but none worked for me. After some more hours trying to solve it found root cause: My device was connected to a guest WIFI which probably has some specific filtering rules which blocked relevant network parts. Switching to a different network solved my problem.
