部署到 Azure 时，Google 身份验证不起作用

Question

我正在使用 Google 进行身份验证。下面的代码在我本地运行时可以正常工作，而当我将其部署到 azure 时会引发错误：

 HttpWebRequest webRequest = 
(HttpWebRequest)WebRequest.Create("https://accounts.google.com/o/oauth2/token");
                    webRequest.Method = "POST";
                    Parameters = "code=" + code + "&client_id=" + googleplus_client_id + "&client_secret=" + googleplus_client_secret + "&redirect_uri=" + googleplus_redirect_url + "&grant_type=authorization_code";
                    byte[] byteArray = Encoding.UTF8.GetBytes(Parameters);
                    webRequest.ContentType = "application/x-www-form-urlencoded";
                    webRequest.ContentLength = byteArray.Length;
                    Stream postStream = webRequest.GetRequestStream();
                    postStream.Write(byteArray, 0, byteArray.Length);
                    postStream.Close();
                    WebResponse response = webRequest.GetResponse();//**Error Occurs here**

我也试过

var values = new NameValueCollection();
var resp = client.UploadValues("https://accounts.google.com/o/oauth2/token?" + Parameters, values );
var responseString = Encoding.Default.GetString(resp);
serStatus = JsonConvert.DeserializeObject<GooglePlusAccessToken>(responseString);

这再次在本地工作，但是当我将它部署到天蓝色时它不起作用

重定向网址如下：

我收到以下错误消息和堆栈跟踪

Answer 1

这可能与重定向 URL 不在 Google 端的批准列表中有关，而在本地运行时使用的 localhost 是。

查看OAuth 2.0 >> Web applications (ASP.NET MVC) 了解更多信息。

希望对你有帮助！
