CookieContainer不会保存来自Set-Cookie Response Header的所有Cookie [英] CookieContainer doesnt save all cookies that come from Set-Cookie Response Header

问题描述

您好，¥b $ b我的问题是，当我使用CookieContainer时，我找不到大多数Cookie，虽然我可以通过Set-Cookie标头获取它们。

这是代码示例

 Dim cookies As New CookieContainer 
 Dim req As HttpWebRequest = DirectCast（WebRequest.Create（" https：// twitter。 com"），HttpWebRequest）
 req.CookieContainer = cookies 
 req.Method =" GET" 
 req.UserAgent =" Mozilla / 5.0（Windows NT 6.1; WOW64; rv：54.0）Gecko / 20100101 Firefox / 54.0" 
 req.Accept =" text / html，application / xhtml + xml，application / xml; q = 0.9，* / *; q = 0.8" 
 req.AutomaticDecompression = DecompressionMethods.GZip或DecompressionMethods.Deflate 
 req.Headers.Add（" DNT"，" 1"）
 req.Headers.Add（" Upgrade-Insecure -Requests"，" 1"）
使用res As HttpWebResponse = DirectCast（req.GetResponse（），HttpWebResponse）
 Console.WriteLine（res.Headers（" Set-Cookie"））'this this IS OUTPUT＃1 
 Console.WriteLine（cookies.GetCookieHeader（req.RequestUri））'这是输出＃2 
结束使用

输出＃1类似于：

 fm = 0; Expires =星期二，2017年8月15日10:24:56 UTC;路径= /;域= .twitter.com;安全;中HTTPOnly，_twitter_sess = BAh7CSIKZmxhc2hJQzonQWN0aW9uQ29udHJvbGxlcjo6Rmxhc2g6OkZsYXNo％250ASGFzaHsABjoKQHVzZWR7ADoPY3JlYXRlZF9hdGwrCFLlbOVdAToMY3NyZl9p％250AZCIlM2YzZGJkZWFhYThiM2E4MDk0ZTNiOWE3MGEwNDBiYjI6B2lkIiVjOGU1％250ANzA1NmRjNTQ2MDk1ZTVkZmJhZDUxNGM0MDljOQ％253D 253D％ -  01b1bf1e46bdc825a81fc425f47aa0bffe21a8a3;路径= /;域= .twitter.com;安全;中HTTPOnly，personalization_id = QUOT; v1_gDOUQU9tZX / K7 + c8n5Q42Q ==英寸; Expires =星期四，2019年8月15日10:25:05 UTC;路径= /;域= .twitter.com，guest_id = V1％3A150279270536074494; Expires =星期四，2019年8月15日10:25:05 UTC;路径= /;域= .twitter.com，CT0 = d04b5e8f8fab836a8c0120ce08359343; Expires =星期二，2017年8月15日16:25:05 UTC;路径= /;域= .twitter.com;安全

输出＃2如下：

 _twitter_sess = BAh7CSIKZmxhc2hJQzonQWN0aW9uQ29udHJvbGxlcjo6Rmxhc2g6OkZsYXNo％250ASGFzaHsABjoKQHVzZWR7ADoPY3JlYXRlZF9hdGwrCFLlbOVdAToMY3NyZl9p％250AZCIlM2YzZGJkZWFhYThiM2E4MDk0ZTNiOWE3MGEwNDBiYjI6B2lkIiVjOGU1％250ANzA1NmRjNTQ2MDk1ZTVkZmJhZDUxNGM0MDljOQ％253D 253D％ -  01b1bf1e46bdc825a81fc425f47aa0bffe21a8a3 

所以，问题是：

如果我为之前的请求使用了CookieContainer，然后我发送了另一个请求与SAME cookie容器，它只是发送了_twitter_sess（我通过fiddler检查过），但它应该发送我从中得到的所有其他的COOK ;的Set-Cookie"
标题..

解决方案

您好Youssef13，

根据您的描述，你想在输出＃1和输出＃2之间显示相同的结果吗？

但是我添加了断点，

使用 res
As HttpWebResponse =
DirectCast （req.GetResponse（） ，
HttpWebResponse ），
我发现res中有一个计数cookie。所以我不清楚这个。

这是链接，你可以参考：

Best此致，

Hello,
My issue is that I don't find most of cookies when I use CookieContainer although I can get them by Set-Cookie header.
Here is a code sample

        Dim cookies As New CookieContainer
        Dim req As HttpWebRequest = DirectCast(WebRequest.Create("https://twitter.com"), HttpWebRequest)
        req.CookieContainer = cookies
        req.Method = "GET"
        req.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:54.0) Gecko/20100101 Firefox/54.0"
        req.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"
        req.AutomaticDecompression = DecompressionMethods.GZip Or DecompressionMethods.Deflate
        req.Headers.Add("DNT", "1")
        req.Headers.Add("Upgrade-Insecure-Requests", "1")
        Using res As HttpWebResponse = DirectCast(req.GetResponse(), HttpWebResponse)
            Console.WriteLine(res.Headers("Set-Cookie")) 'THIS IS OUTPUT #1
            Console.WriteLine(cookies.GetCookieHeader(req.RequestUri)) 'THIS IS OUTPUT #2
        End Using

The output #1 is like:

fm=0; Expires=Tue, 15 Aug 2017 10:24:56 UTC; Path=/; Domain=.twitter.com; Secure; HTTPOnly,_twitter_sess=BAh7CSIKZmxhc2hJQzonQWN0aW9uQ29udHJvbGxlcjo6Rmxhc2g6OkZsYXNo%250ASGFzaHsABjoKQHVzZWR7ADoPY3JlYXRlZF9hdGwrCFLlbOVdAToMY3NyZl9p%250AZCIlM2YzZGJkZWFhYThiM2E4MDk0ZTNiOWE3MGEwNDBiYjI6B2lkIiVjOGU1%250ANzA1NmRjNTQ2MDk1ZTVkZmJhZDUxNGM0MDljOQ%253D%253D--01b1bf1e46bdc825a81fc425f47aa0bffe21a8a3; Path=/; Domain=.twitter.com; Secure; HTTPOnly,personalization_id="v1_gDOUQU9tZX/K7+c8n5Q42Q=="; Expires=Thu, 15 Aug 2019 10:25:05 UTC; Path=/; Domain=.twitter.com,guest_id=v1%3A150279270536074494; Expires=Thu, 15 Aug 2019 10:25:05 UTC; Path=/; Domain=.twitter.com,ct0=d04b5e8f8fab836a8c0120ce08359343; Expires=Tue, 15 Aug 2017 16:25:05 UTC; Path=/; Domain=.twitter.com; Secure

While the output #2 is like:

_twitter_sess=BAh7CSIKZmxhc2hJQzonQWN0aW9uQ29udHJvbGxlcjo6Rmxhc2g6OkZsYXNo%250ASGFzaHsABjoKQHVzZWR7ADoPY3JlYXRlZF9hdGwrCFLlbOVdAToMY3NyZl9p%250AZCIlM2YzZGJkZWFhYThiM2E4MDk0ZTNiOWE3MGEwNDBiYjI6B2lkIiVjOGU1%250ANzA1NmRjNTQ2MDk1ZTVkZmJhZDUxNGM0MDljOQ%253D%253D--01b1bf1e46bdc825a81fc425f47aa0bffe21a8a3

So, The problem is:
If I used a CookieContainer for the previous request, and then I sent another request with the SAME cookie container, it just sent the _twitter_sess ( I checked that by fiddler ), but it should send ALL OF THE OTHER COOKIES that I get from "Set-Cookie" Header..

解决方案

Hi Youssef13,

According to your description, you want to display the same result between output #1 and output #2?

But I add breakpoint in ,

Usingres AsHttpWebResponse= DirectCast(req.GetResponse(), HttpWebResponse), and I find there is one count cookie in res. So I am not clear about this.

Here is the link, you can refer to:
