HttpClient problem with redirect handle and facebook login without browser
I spent three weeks to find a solution to login on facebook home without browser. I wrote this example code but it return an error:
org.apache.commons.httpclient.HttpMethodDirector isRedirectNeeded INFO: Redirect requested but followRedirects is disabled
Code:
import java.io.IOException;
import org.apache.commons.httpclient.Cookie;
import org.apache.commons.httpclient.Header;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpException;
import org.apache.commons.httpclient.HttpState;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.HttpVersion;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.cookie.CookiePolicy;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.methods.PostMethod;
import org.apache.commons.httpclient.params.HttpClientParams;
public class formLogin {
public static void main(String[] args) throws HttpException, IOException {
// Set target URL
String strURL = "http://www.facebook.com/login.php";;
System.out.println("Target URL: " + strURL);
// Get initial state object
HttpState initialState = new HttpState();
// Initial set of cookies can be retrieved from persistent storage
// and re-created, using a persistence mechanism of choice,
//Cookie mycookie = new Cookie(".foobar.com", "mycookie", "stuff",
// "/", null, false);
// and then added to your HTTP state instance
//initialState.addCookie(mycookie);
// Get HTTP client instance
HttpClient httpclient = new HttpClient();
httpclient.getHttpConnectionManager().
getParams().setConnectionTimeout(30000);
// do not set preemptive, this forces Basic authentication which is not what we want
httpclient.getHostConfiguration().getParams()
.setParameter(HttpClientParams.PROTOCOL_VERSION, HttpVersion.HTTP_1_1);
httpclient.setState(initialState);
// RFC 2101 cookie management spec is used per default
// to parse, validate, format & match cookies
//httpclient.getParams().setCookiePolicy(CookiePolicy.RFC_2109);
// A different cookie management spec can be selected
// when desired
//httpclient.getParams().setCookiePolicy(CookiePolicy.NETSCAPE);
// Netscape Cookie Draft spec is provided for completeness
// You would hardly want to use this spec in real life situations
httpclient.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
// Compatibility policy is provided in order to mimic cookie
// management of popular web browsers that is in some areas
// not 100% standards compliant
// Get HTTP GET method
GetMethod httpget = new GetMethod(strURL);
// Execute HTTP GET
int result = httpclient.executeMethod(httpget);
// Display status code
System.out.println("Response status code: " + result);
// Get all the cookies
Cookie[] cookies = httpclient.getState().getCookies();
// Display the cookies
System.out.println("Present cookies: ");
for (int i = 0; i < cookies.length; i++) {
System.out.println(" - " + cookies[i].toExternalForm());
}
// Release current connection to the connection pool
// once you are done
httpget.releaseConnection();
//Cookie ist da und Jetzt wird eingeloggt
PostMethod postMethod = new PostMethod("http://facebook.com/login.php");
NameValuePair[] postData = new NameValuePair[2];
postData[0] = new NameValuePair("email", "******");
postData[1] = new NameValuePair("pass", "******");
postMethod.setRequestBody(postData);
for(int i = 0; i < cookies.lengt开发者_StackOverflow中文版h; i++){
postMethod.setRequestHeader("Cookie:",cookies[i].toExternalForm());
}
try {
httpclient.executeMethod(postMethod);
int statuscode = postMethod.getStatusCode();
System.out.println("STATUS CODE = "+statuscode);
} catch (HttpException httpe) {
System.err.print("HttpException");
System.err.println(httpe.getMessage());
httpe.printStackTrace();
} catch (IOException ioe) {
System.err.print("IOException");
System.err.println(ioe.getMessage());
ioe.printStackTrace();
}
String responseBody = postMethod.getResponseBodyAsString();
System.out.println(responseBody);
postMethod.releaseConnection();
}
}
Is this code correct? What do I have to do to follow a redirect? I've already tried with postmethod.setfollowredirect(true)
but the error persists.
PostMethod is an EntityEnclosingMethod. Calling setFollowRedirect() on PostMethod won't work. See:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3
Maybe you should make a HEAD request first, or maybe you could just start off with a different URL. Try "http://www.facebook.com/login.php" instead of the URL you have.
