c# - 如何在 C# 中检索所有 cookie？

Question

根据 fiddler，我希望这些 cookie 在登录后

Set-Cookie: JSESSIONID=value; Version=1; Domain=.domain.com.mx; Path=/
Set-Cookie: saplb_*=value; Version=1; Path=/
Set-Cookie: PortalAlias=portal; Path=/
Set-Cookie: MYSAPSSO2=value;path=/;domain=.domain.com.mx;HttpOnly

因此，我只得到这个 cookie:

Set-Cookie: PortalAlias=portal; Path=/

我有这个登录代码:

string url = "site.com";

string postdata = "user=username&pass=userpass";
byte[] buffer = Encoding.ASCII.GetBytes(postdata);


**// GET cookies from url
getCookies(url)**

// request
HttpWebRequest request = (HttpWebRequest)System.Net.WebRequest.Create(Url);
request.CookieContainer = this.cookies;

// post
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = buffer.Length;
using (Stream postdata_stream = request.GetRequestStream())
  postdata_stream.Write(buffer, 0, buffer.Length);


// response
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
  // here, I expect to receive 4 cookies, but I only get 1
  foreach (Cookie c in response.Cookies) 
  {
    log("Name:" + c.Name);
    log("Value:" + c.Value);
    log("");
    this.cookies.Add(new Cookie(c.Name, c.Value, c.Path, c.Domain));
  }
}

问题是，当我在 fiddler 中检查我的程序响应时，有 4 个 cookie，但为什么我只能读取一个。

更新

通过 GET 为 cookie 添加的代码:

private void getCookies(string url)
{

  // request
  HttpWebRequest request = CreateWebRequestObject(url);
  request.CookieContainer = this.cookies; // protected member

  request.Method = "GET";
  request.UserAgent = "Mozilla/5.0 (Windows NT 5.1; rv:10.0.2) Gecko/20100101 irefox/10.0.2";

  // response
  using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
  {
    foreach (Cookie c in response.Cookies)
    {

        // add cookies to my CookieContainer
        this.cookies.Add(new Cookie(c.Name, c.Value, c.Path, c.Domain));
    }
  }
}

使用 getCookies() 我有 3/4 个 cookie:

Set-Cookie: JSESSIONID=value; Version=1; Domain=.domain.com.mx; Path=/
Set-Cookie: saplb_*=value; Version=1; Path=/
Set-Cookie: PortalAlias=portal; Path=/

但还是需要一个cookie:

Set-Cookie: MYSAPSSO2=value;path=/;domain=.domain.com.mx;HttpOnly

此外，我将请求与 Fiddler/WinMerge 进行了比较:

// program request
$Version=1; saplb_*=value; $Path=/; $Version=1; JSESSIONID=value; $Path=/; Domain=.domain.com.mx
Expect: 100-continue

// firefox request
saplb_*=value; JSESSIONID=value
Connection: keep-alive

为什么我的请求中有一个“$”字符？

使用 Fiddler 比较您从代码发出的 HTTP 请求与从浏览器发出的请求。

为此，选择两个请求并按 CTRL+W(您可能必须按照 these instructions 配置比较工具)

此外，尝试检查从浏览器发起的所有请求。有可能在之前的请求中收到了一些 cookie(通常是您在请求登录页面时发出的 GET 请求)。如果需要，先执行 GET，收集 cookie，然后执行 POST。
