如何使用Cookie容器執行多個發布請求C＃

Question

我正在嘗試在同一會話上執行2個發布請求，但是第二個請求總是給我主頁的html源代碼...

這兩個函數的作用完全相同：執行發布請求並將其添加到Cookie容器中。 在第二個函數的末尾，響應字符串向我發送了主頁的html源頁面，而不是以前的頁面。 而第一個發布請求中的responsetring（在我之前嘗試過的時候）向我發送了很好的html源頁面。

這是我的代碼：

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);
}

這是我的職能部門，它是之前啟動的部門：

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);

如果有人有幫助我的想法，那就太好了！ 非常感謝你！

感謝@Hesam Fraridmehr，這是答案：

在這樣的行中添加：＆：-postData + =“＆style =” + data_style_id;
