c# - "$"美元字符前缀 cookie 名称

Question

我有这个功能来检索 CookieContainer (this.cookies) 中的响应 cookie

private void getCookies(string url)
{

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

  request.Headers.Add("Accept-Encoding", "gzip, deflate");
  request.Headers.Add("Accept-Language", " es-MX,es;q=0.8,en-us;q=0.5,en;q=0.3");
  request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";



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

  // response
  using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
  {
    foreach (Cookie c in response.Cookies)
    {
      this.cookies.Add(new Cookie(c.Name, c.Value, c.Path, c.Domain));


    }
  }
}

但是，当我在 Fiddler 中调试请求时，我得到了这个:

为什么cookie里有个“$”？

根据MSDN

public Cookie( string name, string value, string path, string domain )

name Type: System.String The name of a Cookie. The following characters must not be used inside name: equal sign, semicolon, comma, newline (\n), return (\r), tab (\t), and space character. The dollar sign character ("$") cannot be the first character.

如何删除这个字符？

您看到的 $ 不是 cookie 的名称；它是与 cookie 关联的属性。

RFC 2109处理 HTTP 状态管理； 4.4 节专门讨论了美元符号前缀。希望对您有所帮助...
