将HttpMethod的内容复制到另一个HttpMethod

将HttpMethod的内容复制到另一个HttpMethod

问题描述:

我一直试图在Java代码中处理重定向(302),现在我完成了我的代码。我遇到了另一个问题,在登录后点击我注销的任何链接。所以我通过wireshark检查了我的TCP流,发现缺少几个HeaderRequests。实现我的代码后,HTTP头如下:将HttpMethod的内容复制到另一个HttpMethod

GET /index.php/ HTTP/1.1 
Host: 10.28.161.31 
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.24) Gecko/20111109 CentOS/3.6-3.el5.centos Firefox/3.6.24 
Cookie: PHPSESSID=d488eea5e85afc8ec526c1a749e7ab20; path=/ 
Referrer: http://10.28.161.31 
Cookie: $Version=0; PHPSESSID=d488eea5e85afc8ec526c1a749e7ab20; $Path=/ ??? 

和原始HTTP头如下:

GET/HTTP/1.1 
Host: 10.28.161.31 
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.2.24) Gecko/20111109 CentOS/3.6-3.el5.centos Firefox/3.6.24 
Referer: http://10.28.161.31/index.php

Accept-Language: en-us,en;q=0.5 
Accept-Encoding: gzip,deflate 
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 
Keep-Alive: 115 
Connection: keep-alive 
Cookie: PHPSESSID=978ee1e3b3696743c5c8f507a2ec7212 

据我的观察,我没有正确复制的标题的内容,这就是为什么它正在快速注销。所以我的问题是,如何将HttpMethod的完整内容复制到另一个HttpMethod?如果任何人可以提供代码片段,或者示例/教程会很棒,或者如果任何人能够提醒我我做错事的地方,那将是可观的。

我的实现就在这里:

private HttpMethod loadHttp302Request(HttpMethod method, HttpClient client, 
       int status, String urlString) throws HttpException, IOException { 
    if (status!=302) 
     return null; 
    String[] url = urlString.split("/");   
    HttpMethod theMethod = new GetMethod(urlString + method.getResponseHeader("Location").getValue()); 
    theMethod.setRequestHeader("Cookie", method.getResponseHeader("Set-Cookie") 
        .getValue()); 
    theMethod.setRequestHeader("Referrer",url[0]+"//"+url[2]); 
    int _status = client.executeMethod(theMethod); 
    return theMethod; 
} 

HttpClient的可以自动,如果你设置的策略处理重定向。使用示例Httpclient 4, error 302. How to redirect?
