httpclient对discuz论坛的问题

xuganggogo 2010-06-12 05:23:38

这两天研究了下，关于discuz论坛的发帖，用httpclient实现无验证码的自动发帖。
但是发现有的discuz论坛可以正常发送成功，有的却发送失败。

检查后发现失败的原因是，登录成功后，session没有保存下来，导致访问任何页面都是未登陆状态。不知为什么？求解答

贴出部分方法



public boolean login(HttpClient client, String bbsUrl, String username,

			String password, String formhash, String charset) {

		client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);

		//System.setProperty("apache.commons.httpclient.cookiespec", "BROWSER_COMPATIBILITY ");

		String url = bbsUrl + "/logging.php";

		PostMethod postMethod = new PostMethod(url, charset);

		// 填入各个表单域的值

		NameValuePair[] data = { new NameValuePair("loginfield", "username"),

				new NameValuePair("username", username),

				new NameValuePair("password", password),

				new NameValuePair("formhash", formhash),

				new NameValuePair("questionid", "0"),

				new NameValuePair("answer", ""),

				new NameValuePair("cookietime", "315360000"),

				new NameValuePair("loginmode", "normal"),

				new NameValuePair("action", "login"),

				new NameValuePair("loginsubmit", "true") };

		// 将表单的值放入postMethod中

		postMethod.setRequestBody(data);

		// 执行

		try {

			int status = client.executeMethod(postMethod);

			//用stream读
