部署到天蓝色的Google身份验证不起作用

Question

I am authenticating using Google. The below code works fine when I run it locally whereas it throws an error when I deploy it to azure:

 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**

I also tried

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);

And again this worked locally, but when I deployed it to azure it didn't work

The redirect url is like below:

https://sample.com/Home/User?code=4/uQB37PKUFlID8dSLFFTsYLEDdHWWOprWaMtpa6YasdxxxxxxxxxxH8OQVxg3UZMoDc&scope=email%20profile%20https://www.googleapis.com/auth/userinfo.profile%20https://www.googleapis.com/auth/userinfo.email

I get the below error message and stack trace

Answer 1

It might be related to the redirect URL not being in the approved list at the Google side, whereas the localhost used when you run locally is.

Take a look at OAuth 2.0 >> Web applications (ASP.NET MVC) for more information.

Hope it helps!
