Cookies無法在Windows Phone上使用WebClient正常工作

Question

我的問題是，當我使用新的Web客戶端將URL發送到WebService時，它要求我登錄，在搜索了此問題后，我發現您需要保存Cookie，但它不能與我一起使用。

根據您的要求，這是完整的代碼

    public partial class MainPage : PhoneApplicationPage

            string baseuri = "http://IP in the comment/vertexweb10/webservice.svc/login?username=%22user15650%22&password=%22898k%22";
            CookieAwareWebClient wc = new CookieAwareWebClient();

            Uri uri = new Uri(baseuri);
            wc.DownloadStringAsync(uri);
        }

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

            MessageBox.Show(webResponse as string);
            var outerRoot = JsonConvert.DeserializeObject<OuterRootObject>(webResponse);

            if (UserIdVal == -1 || UserIdVal == -207)
                MessageBox.Show("Invalid username or password");
            else if (UserIdVal == -231)
            {
                MessageBox.Show("You must have at least one account");
            }

            else if (webResponse == null || webResponse == "" || UserIdVal < 0)

        }

                cookie = givenContainer;
            }
        }
    }
}

我認為錯誤是在cookie容器中，這是我使用的最后一個cookieaware（我嘗試了超過10個cookie容器代碼）

Answer 1

這是代碼，它的作用是調用第一個Url並在響應良好的情況下獲取響應，它將Cookie復制到sessionCookie變量。 並在第二次通話中使用

在同一頁面的某些位置聲明sessioncookie

public static CookieContainer sessionCookie;

並將其復制到您的按鈕中，單擊

  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();

            }
     }
  }

Answer 2

我已經使用解決了我的問題

request.CookieContainer = cookieJar;

然后我在第二個請求上使用相同的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);
