[clear][done]python 中如何追加自定义的cookie
本帖最后由 bxfqing 于 2014-09-08 21:36 编辑背景描述：
测试页面有如下的javascript，# <script type="text/javascript">
# //Check Login
# function checkLogin(){
# if(status && data.info){
# ds.setCookie('username', username, 30);
# toggleToken(status);
# 。。。。。。
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
cookieFilename = 'demolocalCookies.txt'
g_cookiejar = cookielib.LWPCookieJar(cookieFilename)
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(g_cookiejar))
urllib2.install_opener(opener)
g_cookiejar.set_cookie(c)
print "DBG >>> Cookie=== :before urllib2.urlopen\n\t",g_cookiejar
check_us_req = urllib2.Request(check_userstatus_url,None,check_us_headers)
check_us_response = urllib2.urlopen(check_us_req)
check_us_result = check_us_response.read()
print "DBG >>> Cookie=== :after urllib2.urlopen\n\t",g_cookiejar
输出的调试信息DBG >>> Cookie=== :before urllib2.urlopen
<_LWPCookieJar.LWPCookieJar[<Cookie NSC_qbttqpsu=ffffffffc3a0da7e45525d5f4f58455e445a4a423660 for passport.feng.com/>, <Cookie PHPSESSID=jt545q6regkj5me21k9rcqkbf5 for passport.feng.com/>, <Cookie username=1111 for passport.feng.com/>]>
DBG >>> Cookie=== :after urllib2.urlopen
<_LWPCookieJar.LWPCookieJar[<Cookie NSC_qbttqpsu=ffffffffc3a0da7e45525d5f4f58455e445a4a423660 for passport.feng.com/>, <Cookie PHPSESSID=jt545q6regkj5me21k9rcqkbf5 for passport.feng.com/>]>
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) 本帖最后由 bxfqing 于 2014-09-08 21:36 编辑
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
def add_cookie_header(self, request):
"""Add correct Cookie: header to request (urllib2.Request object).
The Cookie2 header is also added unless policy.hide_cookie2 is true.
"""
_debug("add_cookie_header")
self._cookies_lock.acquire()
try:
self._policy._now = self._now = int(time.time())
cookies = self._cookies_for_request(request)
print '---',cookies
attrs = self._cookie_attrs(cookies)
print '+++',attrs
if attrs:
if not request.has_header("Cookie"):
request.add_unredirected_header(
"Cookie", "; ".join(attrs))
print '<<< ',"Cookie","; ".join(attrs)
# if necessary, advertise that we know RFC 2965
if (self._policy.rfc2965 and not self._policy.hide_cookie2 and
not request.has_header("Cookie2")):
for cookie in cookies:
if cookie.version != 1:
request.add_unredirected_header("Cookie2", '$Version="1"')
break
finally:
self._cookies_lock.release()
self.clear_expired_cookies()
print '>>>',self._cookies_for_request(request)
可以POST是带自定义的cookie信息了；
