c# - 如何使用cookie容器执行多个发布请求

Question

我试图在同一个会话上做 2 个 post 请求，但第二个总是给我主页的 html 源代码......这两个函数做的完全一样：做一个 post 请求并将它添加到 cookie 容器中。在第二个函数结束时，响应字符串向我发送主页的 html 源页面，而不是我之前的那个。而第一个帖子请求中的 responsetring（当我之前尝试过时）向我发送了好的 html 源页面。这是我的代码：private CookieContainer cookieContainer;private void SendRequest_add_to_cart(string url, string data_style_id, string size){    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);    request.ContentType = "application/x-www-form-urlencoded";    request.Method = "POST";    if (this.cookieContainer != null)        request.CookieContainer = this.cookieContainer;    else        request.CookieContainer = new CookieContainer();    var postData = "utf8=✓";    postData += "style=" + data_style_id;    postData += "size=" + size;    postData += "commit=add to basket";    var data = Encoding.ASCII.GetBytes(postData);    request.ContentLength = data.Length;    using (var stream = request.GetRequestStream())    {        stream.Write(data, 0, data.Length);    }    var response = (HttpWebResponse)request.GetResponse();    var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();    this.cookieContainer = request.CookieContainer;}private void SendRequest_checkout(string url){    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);    request.ContentType = "application/x-www-form-urlencoded";    request.Method = "POST";    if (this.cookieContainer != null)        request.CookieContainer = this.cookieContainer;    else        request.CookieContainer = new CookieContainer();    var postData = "utf8=✓";    postData += "order[billing_name]=toto";    postData += "order[email]=[e-mail]";    var data = Encoding.ASCII.GetBytes(postData);    request.ContentLength = data.Length;    using (var stream = request.GetRequestStream())    {        stream.Write(data, 0, data.Length);    }如果有人有想法来帮助我，那就太好了！非常感谢！
