标题: [clear][done]python 中如何追加自定义的cookie


背景描述：
测试页面有如下的javascript，

1. #       <script type="text/javascript">
   
2. #        //Check Login
   
3. #        function checkLogin(){
   
4. #                    if(status && data.info){
   
5. #                        ds.setCookie('username', username, 30);
   
6. #                        toggleToken(status);
   
7. # 。。。。。。
   

复制代码

打开网页，输入测试用户名：
654        25.637813        192.168.66.151        61.164.241.82        HTTP        756        GET /index.php?r=user/CheckUserStatus&username=1111&password=&_=1408949763960 HTTP/1.1
抓包看到的 当前cookie
PHPSESSID=ujbf0iqsfmkscqomipdvprs4s3; NSC_qbttqpsu=ffffffffc3a0da7e45525d5f4f58455e445a4a423660
输入测试pwd
1280        201.741714        192.168.66.151        61.164.241.82        HTTP        786        GET /index.php?r=user/CheckUserStatus&username=1111&password=11111&_=1408949940047 HTTP/1.1
js脚本会把当前用户添加到cookie中；
PHPSESSID=ujbf0iqsfmkscqomipdvprs4s3; NSC_qbttqpsu=ffffffffc3a0da7e45525d5f4f58455e445a4a423660; username=1111

我用python来模拟这个过程，使用的是LWPcookieJar

1.         
   
2.         cookieFilename = 'demolocalCookies.txt'
   
3.         g_cookiejar = cookielib.LWPCookieJar(cookieFilename)     
   
4.         opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(g_cookiejar))
   
5.         urllib2.install_opener(opener)
   

复制代码

1.         g_cookiejar.set_cookie(c)
   
2.         print "DBG >>> Cookie  === :before urllib2.urlopen\n\t",g_cookiejar
   
3.         check_us_req = urllib2.Request(check_userstatus_url,None,check_us_headers)
   
4.         check_us_response = urllib2.urlopen(check_us_req)
   
5.         check_us_result = check_us_response.read()
   
6.         print "DBG >>> Cookie  === :after urllib2.urlopen\n\t",g_cookiejar
   

复制代码

输出的调试信息

1. DBG >>> Cookie  === :before urllib2.urlopen
   
2.         <_LWPCookieJar.LWPCookieJar[<Cookie NSC_qbttqpsu=ffffffffc3a0da7e45525d5f4f58455e445a4a423660 for passport.feng.com/>, <Cookie PHPSESSID=jt545q6regkj5me21k9rcqkbf5 for passport.feng.com/>, <Cookie username=1111 for passport.feng.com/>]>
   
3. DBG >>> Cookie  === :after urllib2.urlopen
   
4.         <_LWPCookieJar.LWPCookieJar[<Cookie NSC_qbttqpsu=ffffffffc3a0da7e45525d5f4f58455e445a4a423660 for passport.feng.com/>, <Cookie PHPSESSID=jt545q6regkj5me21k9rcqkbf5 for passport.feng.com/>]>
   

复制代码

有些疑问，在urlopen前，cookie都是三行，为什么抓包的时候，http request 中的cookie还是原来的2行了，cookie始终没有携带username发起请求？
我也试过下面的几个方法，都不行，目前比较迷茫，到底哪里写的不对
+CookieJar.add_cookie_header(request)
+CookieJar.set_cookie(cookie)
+Request.add_header(key, val)

更新，Cookie构造方法有问题：
我把/usr/lib/python2.7/cookielib.py的源代码加了debug信息

1. 
   
2.     def add_cookie_header(self, request):
   
3.         """Add correct Cookie: header to request (urllib2.Request object).
   
4. 
   
5.         The Cookie2 header is also added unless policy.hide_cookie2 is true.
   
6. 
   
7.         """
   
8.         _debug("add_cookie_header")
   
9.         self._cookies_lock.acquire()
   
10.         try:
    
11. 
    
12.             self._policy._now = self._now = int(time.time())
    
13. 
    
14.             cookies = self._cookies_for_request(request)
    
15.             print '---',cookies
    
16. 
    
17.             attrs = self._cookie_attrs(cookies)
    
18.             print '+++',attrs
    
19.             if attrs:
    
20.                 if not request.has_header("Cookie"):
    
21.                     request.add_unredirected_header(
    
22.                         "Cookie", "; ".join(attrs))
    
23.                     print '<<< ',"Cookie","; ".join(attrs)
    
24. 
    
25.             # if necessary, advertise that we know RFC 2965
    
26.             if (self._policy.rfc2965 and not self._policy.hide_cookie2 and
    
27.                 not request.has_header("Cookie2")):
    
28.                 for cookie in cookies:
    
29.                     if cookie.version != 1:
    
30.                         request.add_unredirected_header("Cookie2", '$Version="1"')
    
31.                         break
    
32. 
    
33.         finally:
    
34.             self._cookies_lock.release()
    
35. 
    
36.         self.clear_expired_cookies()
    
37.         print '>>>',self._cookies_for_request(request)

可以POST是带自定义的cookie信息了；
