“$”美元字符前缀cookie名称 [英] "$" dollar character prefixing cookies names
问题描述
我有这个函数来检索CookieContainer中的响应cookie(this.cookies)
I have this function to retreive response cookies in a CookieContainer (this.cookies)
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:
But, when I debug the request in Fiddler, I get this:
为什么Cookie中有一个$?
Why there is a "$" in cookies?
根据 MSDN
public Cookie(字符串名称,字符串值,字符串路径,字符串
domain)
public Cookie( string name, string value, string path, string domain )
/ strong>
类型:System.String
Cookie的名称。在名称中不能使用以下字符:等号,分号,逗号,换行符(\\\
),return(\r),
制表符(\t)和空格字符。美元符号字符($)不能将
作为第一个字符。
name Type: System.String The name of a Cookie. The following characters must not be used inside name: equal sign, semicolon, comma, newline (\n), return (\r), tab (\t), and space character. The dollar sign character ("$") cannot be the first character.
推荐答案
您看到的$不是cookie的名称它是与Cookie关联的属性。
The $ you see is not the name of the cookie; it is an attribute associated with a cookie.
