Hello,I've to submit post form with username,password and 2 hidden
parameters.It seems to be logged in, but then redirection fails: import
java.io.IOException;import org.apache.commons.httpclient.*;import
org.apache.commons.httpclient.cookie.CookiePolicy;import
org.apache.commons.httpclient.cookie.CookieSpec;import
org.apache.commons.httpclient.methods.*; public class FormLogin{ static
final String LOGON_SITE = "www.website.org"; static final int LOGON_PORT
= 80; public FormLogin() { super(); } public static void
main(String[] args) throws Exception { HttpClient client = new
HttpClient(); client.getHostConfiguration().setHost(LOGON_SITE,
LOGON_PORT, "http");
client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY); //
'developer.java.sun.com' has cookie compliance problems // Their session
cookie's domain attribute is in violation of the RFC2109 // We have to
resort to using compatibility cookie policy GetMethod authget = new
GetMethod("/servlet/SessionServlet"); client.executeMethod(authget);
System.out.println("Login form get: " + authget.getStatusLine().toString());
// release any connection resources used by the method
authget.releaseConnection(); // See if we got any cookies
CookieSpec cookiespec = CookiePolicy.getDefaultSpec(); Cookie[]
initcookies = cookiespec.match( LOGON_SITE, LOGON_PORT, "/", false,
client.getState().getCookies()); System.out.println("Initial set of
cookies:"); if (initcookies.length == 0) {
System.out.println("None"); } else { for (int i = 0; i <
initcookies.length; i++) { System.out.println("- " +
initcookies[i].toString()); } } PostMethod
authpost = new PostMethod("/"); // Prepare login parameters
NameValuePair action = new NameValuePair("submit", "entra!");
NameValuePair url = new NameValuePair("statuslg", "ok");
NameValuePair userid = new NameValuePair("usr", "user"); NameValuePair
password = new NameValuePair("pwd", "password");
authpost.setRequestBody( new NameValuePair[] {action, url, userid,
password}); client.executeMethod(authpost);
System.out.println("Login form post: " + authpost.getStatusLine().toString());
// release any connection resources used by the method
authpost.releaseConnection(); // See if we got any cookies // The
only way of telling whether logon succeeded is // by finding a session
cookie Cookie[] logoncookies = cookiespec.match( LOGON_SITE,
LOGON_PORT, "/", false, client.getState().getCookies());
System.out.println("Logon cookies:"); if (logoncookies.length == 0)
{ System.out.println("None"); } else { for
(int i = 0; i < logoncookies.length; i++) {
System.out.println("- " + logoncookies[i].toString()); }
} // Usually a successful form-based login results in a redicrect to
// another url int statuscode = authpost.getStatusCode(); if
((statuscode == HttpStatus.SC_MOVED_TEMPORARILY) || (statuscode ==
HttpStatus.SC_MOVED_PERMANENTLY) || (statuscode ==
HttpStatus.SC_SEE_OTHER) || (statuscode ==
HttpStatus.SC_TEMPORARY_REDIRECT)) {
//authpost.setFollowRedirects(true); Header header =
authpost.getResponseHeader("location"); if (header != null) {
String newuri = header.getValue(); if ((newuri == null)
|| (newuri.equals(""))) { newuri = "/"; }
System.out.println("Redirect target: " + newuri);
GetMethod redirect = new GetMethod(newuri);
redirect.setRequestHeader("Cookie",logoncookies.toString());
client.executeMethod(redirect); byte[] responseBody =
redirect.getResponseBody(); System.out.println("Redirect: " +
redirect.getStatusLine().toString());
System.out.println("Redirect: " + redirect.getRequestHeader("path"));
// release any connection resources used by the method
redirect.releaseConnection(); } else {
System.out.println("Invalid redirect"); System.exit(1);
} } } I obtain code 302 for login page,
andauthpost.getResponseHeader("location")=/default.php (that's correct)but
redirection doesn't work and variable responseBody contains html code from
login page (index.php)Any idea, please?
