最近在研究使用httpclient4 但是每次测试都不能成功穿透校内啊 discuz啊不知道为什么，代码如下



import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.util.ArrayList;

import java.util.List;



import org.apache.http.Header;

import org.apache.http.HttpEntity;

public class TestDiscuz {

  private static String DiscuzLoginURL = "http://www.discuz.net/member.php?mod=logging&action=login&loginsubmit=yes";  

	

	private static String userName = "rosewj";  

    private static String password = "860111";  

    

    private static  HttpResponse response;  

    

    

	public static void main(String[] args) {

		DefaultHttpClient httpclient = new DefaultHttpClient();

	    // HttpClientParams.setCookiePolicy(httpclient.getParams(),CookiePolicy.BROWSER_COMPATIBILITY); 这行如果不注释的话一些特殊字符的cookie就会丢失

	     

	     try{

	    	 HttpPost httpost = new HttpPost(DiscuzLoginURL);  

	          List<NameValuePair> nvps = new ArrayList<NameValuePair>();  

	          nvps.add(new BasicNameValuePair("password", password));  

	          nvps.add(new BasicNameValuePair("username", userName));  

	          nvps.add(new BasicNameValuePair("loginsubmit", "1"));  

	          httpost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));  

	          response = httpclient.execute(httpost);  

	          HttpEntity entity = response.getEntity();  

	                 if (entity == null)  

	                      throw new Exception("登录失败了");  

	                  List<Cookie> cookies = httpclient.getCookieStore().getCookies();// 获得登录后的Cookie列表  

	                  System.out.println("httpclient cookie _____________");

			             for(int i=0;i<cookies.size();i++) {

			            	 System.out.println(cookies.get(i).getName());

			            	 System.out.println(cookies.get(i).getValue());

			             }

			             System.out.println("httpclient cookie _____________");

	          entity.consumeContent();

		          httpost1.setEntity(new UrlEncodedFormEntity(nvps1, HTTP.UTF_8));  

		             response = httpclient.execute(httpost1);

		            // entity1.consumeContent();

	     }catch(Exception e) {

	    	 

	     }

	}

造成"您的请求来路不正确，无法提交。"的原因有2：
1.formhash不正确
2.HTTP_REFERER 跟当前域名不一致

是不是你的java程序里面没有伪造 HTTP_REFERER?

至于formhash，计算方法是 substr(md5(substr($_G['timestamp'], 0, -7).$_G['username'].$_G['uid'].$_G['authkey'].$hashadd.$specialadd), 8, 8);
跟其他的无关，只跟当前的账户关联。
