【问题描述】：

我的问题是，当我使用新的 webclient 向 WebService 发送 url 时，它要求我登录，在搜索了这个问题后，我发现你需要保存 cookie，但它对我不起作用。

根据您的要求，这是完整代码

        private void ParseProducts_AsJson(object sender, DownloadStringCompletedEventArgs e)
        {
            string raw = e.Result;
            string webResponse = e.Result;

            MessageBox.Show(webResponse as string);

        }

        class CookieAwareWebClient : WebClient
        {
            [System.Security.SecuritySafeCritical]
            private CookieContainer cookie;

            public CookieContainer Cookie { get { return cookie; } }

            public CookieAwareWebClient()
            {
                cookie = new CookieContainer();
            }

            public CookieAwareWebClient(CookieContainer givenContainer)
            {
                cookie = givenContainer;
            }
        }
    }
}

我认为错误出在 cookie 容器中，这是我使用的最后一个 cookieaware（我已经尝试了 10 多个 cookie 容器代码）

【解决方案1】：

这是代码，它的作用是调用第一个 Url 并获得响应，如果响应良好，它将 cookie 复制到 sessionCookie 变量。并在第二次调用中使用它

在同一页面的某个位置声明 sessioncookie

public static CookieContainer sessionCookie;

然后将其复制到您的按钮单击中

  public static async Task<string> SendRequestGetResponse()
    {
        try
        {
                   var postRequest = (HttpWebRequest)WebRequest.Create("http://74.54.46.178/vertexweb10/webservice.svc/login?username=%22user15650%22&password=%22898k%22");

            postRequest.Method = "GET";
            if (sessionCookie == null)
            {
                postRequest.CookieContainer = new CookieContainer();
            }
            else
            {
                postRequest.CookieContainer = sessionCookie;
            }

            HttpWebResponse postResponse = (HttpWebResponse)await postRequest.GetResponseAsync();

            if (postResponse != null)
            {
                var postResponseStream = postResponse.GetResponseStream();
                var postStreamReader = new StreamReader(postResponseStream);

                string response = await postStreamReader.ReadToEndAsync();

                if (sessionCookie == null)
                {
                    sessionCookie = postRequest.CookieContainer;
                }
            }

        var postRequest1 = (HttpWebRequest)WebRequest.Create("http://74.54.46.178/vertexweb10/webservice.svc/getallsymbols?AccountID=1122336675");              
            postRequest1.Method = "GET";
            if (sessionCookie == null)
            {
                postRequest1.CookieContainer = new CookieContainer();
            }
            else
            {
                postRequest1.CookieContainer = sessionCookie;
            }

            HttpWebResponse postResponse1 = (HttpWebResponse)await postRequest1.GetResponseAsync();

            if (postResponse1 != null)
            {
                var postResponseStream1 = postResponse1.GetResponseStream();
                var postStreamReader1 = new StreamReader(postResponseStream1);

                string response1 = await postStreamReader1.ReadToEndAsync();

            }
     }
  }

【讨论】：

它不起作用，我不知道是什么问题，我认为是因为收到的cookie是httpOnly，请指教
您能否分享您为登录请求和其他请求设置标头（如内容类型、请求类型等）的代码。我已经编辑了我的答案，并包含了我为请求设置标头的部分。
亲爱的 Jagath，这是我使用的完整代码，IP 是 74.54.46.178，我知道它的代码不好，因为我是编程新手，请帮助我这样做
我已经用我的代码编辑了我的答案，因为我得到了成功的回报。
对不起，亲爱的，它不能使用我的代码，你能帮我处理我的代码吗？我的意思是使用类 CookieAwareWebClient : WebClient

【解决方案2】：

我已经使用

解决了我的问题

request.CookieContainer = cookieJar;

然后我在第二个请求中使用相同的 cookieJar

var request = HttpWebRequest.Create(new Uri("http://x.x.x.x/vertexweb10/webservice.svc/getallsymbols?AccountID=1122336675")) as HttpWebRequest;
request.Method = "GET";
request.CookieContainer = cookieJar;
request.BeginGetResponse(ar =>
{
    HttpWebRequest req2 = (HttpWebRequest)ar.AsyncState;
    using (var response = (HttpWebResponse)req2.EndGetResponse(ar))
    {
        using (Stream stream = response.GetResponseStream())
        {
            using (var reader = new StreamReader(stream))
            {




                //the code you need


            }
        }

    }

}, request);
