Question

我正在尝试在同一个会话上发布2个帖子请求，但第二个请求总是给我主页的html源代码...

2个函数完全相同：执行post请求并将其添加到cookie容器中。在第二个函数的末尾，respontring字符串向我发送主页的html源页面而不是之前的那个页面。而在第一个帖子请求中的响应字符串（当我之前尝试过它）发送给我一个好的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]=toto@gmail.com";
    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;
    Console.WriteLine(responseString);
}

这是我的功能之前推出的那个：

var url_add_to_cart = link_general + doc.DocumentNode.SelectSingleNode("//form").Attributes["action"].Value;
var url_checkout = link_general + "/checkout.json";

    SendRequest_add_to_cart(url_add_to_cart, data_style_id, size);
    SendRequest_checkout(url_checkout);

如果有人有想法帮助我，那就太好了！非常感谢你！

感谢@Hesam Fraridmehr，答案是：

添加：＆amp;到这样的行： -postData + =“＆amp; style =”+ data_style_id;
