如何在C＃中使用HttpWebRequest發送Cookie

Question

我用6個文本框制作了簡短的程序，並手動填寫了cookie。 現在，我希望我的程序對特定的URL進行操作，就好像它已登錄一樣。

我該怎么辦？ 我嘗試了此操作，但收到未登錄的http響應。

            string url = "myurl string";
            Uri target = new Uri(url);
            CookieContainer gaCookies = new CookieContainer();
            gaCookies.Add(new Cookie("__utma", textBox1.Text) { Domain= target.Host});
            gaCookies.Add(new Cookie("__utmb", textBox2.Text) { Domain = target.Host });
            gaCookies.Add(new Cookie("__utmc", textBox3.Text) { Domain = target.Host });
            gaCookies.Add(new Cookie("__utmz", textBox4.Text) { Domain = target.Host });
            gaCookies.Add(new Cookie("cookiename1", textBox5.Text) { Domain = target.Host });
            gaCookies.Add(new Cookie("cookiename2", textBox6.Text) { Domain = target.Host });
            HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(url);
            HttpWebResponse response = (HttpWebResponse)myReq.GetResponse();
            Stream receiveStream = response.GetResponseStream();
            StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);
            textBox7.Text = readStream.ReadToEnd();

您需要設置HTTP請求的cookie容器。 創建HtppWebRequest之后，添加以下行。

myReq.CookieContainer = gaCookies
