I have created web api method to insert some data. It works fine anonymously. But when I decorate the method with [Authorize] , I recieve message like "Message": "Authorization has been denied for this request." jwt bearer token was entered with the request.I run the function using Postman. Should I add any class to validate the bearer token?
[Authorize]
[Route("customer")]
public String customer(APICustomer APICustomer1)
{
try
{
insert_Customer(APICustomer1.custid, APICustomer1.custname, APICustomer1.status);
}
catch (Exception ex)
{
}
return "1";
}
Authentication is the process of validating user credentials and authorization is the process of checking privileges for a user to access specific modules in an application.

I am developing a C# Web Api (.NET Framework) and would like to use in parallel the AAD authentication (already working correctly) and Google Authentication. This means, my clients (javascript or just Postman) should fetch the token, include it in the Authorization header (Bearer token) and be able to execute the API methods.
However, it seems that the token I am generating with Postman is not accepted by my C# Web Api. I am always getting a HTTP 401. The AAD (Windows Azure Active Directory) works seamlessly.
Using a C# Web Api (.Net Framework 4.6.1), including Microsoft.Owin.Security.Google Nuget package v.4.0.1.
I have created the Oauth client on the google developer console, got my client ID and client secret. Also I have set up the redirect URI there.
I am using Postman Oauth2 authorization, setting following parameters:
Grant type: implicit
Callback URL: my url
AUth URL: https://accounts.google.com/o/oauth2/v2/auth
Client ID: 65xxxxxmyclientid.apps.googleusercontent.com
scope: openid email profile
Then I can log in with my google account, give consent to use the scopes, and am getting the token like this:
Access Token
ya29.Gls7....
This token is then sent as Authorization header like "Bearer ya29.Gls7...."
Startup.Auth
public void ConfigureAuth(IAppBuilder app)
{
app.UseWindowsAzureActiveDirectoryBearerAuthentication(
new WindowsAzureActiveDirectoryBearerAuthenticationOptions
{
Tenant = ConfigurationManager.AppSettings["ida:Tenant"],
TokenValidationParameters = new TokenValidationParameters
{
ValidAudience = ConfigurationManager.AppSettings["ida:Audience"]
},
});
app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
{
ClientId = ConfigurationManager.AppSettings["GoogleClientId"],
ClientSecret = ConfigurationManager.AppSettings["GoogleClientSecret"],
});
}
ValuesController
public class ValuesController : ApiController
{
[Authorize]
// GET api/values/5
public string Get(int id)
{
return "value";
}
}
Every time I call the API using Postman, I am getting a 401, even though the bearer token is included in the request authorization header.
HTTP GET https://localhost:44385/api/values/1
Edit: There is no custom code from my side which would validate the token. I assumed that is being done automatically by the library. In fact, this is done automatically for AAD tokens, but not in the case of Google Oauth.
I expect to get inside the code of the controller method, having at least the identity name set with the google account name/email.
What am I missing to be authenticated inside my controller method with google account?
When User Sign In Gmail account via Oauth2 protocol and finish it, my server get authorization code and I make exchange this code for refresh token and access token, everything works as planned but I need to get email address too. I mean if user logged in as helloworld#gmail.com, somehow with authorization code I would like to know this address, may I somehow to know it?
This is endpoint where I exchange authorization code on access token and refresh token:
public OAuth2AccessToken oauth(String authorizationCode) {
AuthorizationCodeResourceDetails resource = new AuthorizationCodeResourceDetails();
resource.setUserAuthorizationUri(userAuthorizationUri);
resource.setAccessTokenUri(accessTokenUri);
resource.setClientId(clientId);
resource.setClientSecret(clientSecret);
resource.setPreEstablishedRedirectUri(redirectUrl);
resource.setScope(scopes);
resource.setUseCurrentUri(false);
AccessTokenRequest request = new DefaultAccessTokenRequest();
request.setPreservedState(new Object());
request.setAuthorizationCode(authorizationCode);
AuthorizationCodeAccessTokenProvider provider = new AuthorizationCodeAccessTokenProvider();
OAuth2AccessToken accessToken = provider.obtainAccessToken(resource, request);
return accessToken;
}
I don't have WebSecurityConfigurerAdapter for OAuth2
If the user's email address is not already provided in the id_token part of the oauth2 response, you can use the Gmail API Users.getProfile operation, using the special value "me" as the userId to refer to the authenticated user.
See: https://developers.google.com/gmail/api/v1/reference/users/getProfile
That should give you a response like:
{
"emailAddress": -string-,
"messagesTotal": -integer-,
"threadsTotal": -integer-,
"historyId": -unsigned long-
}
i have created a laravel socialte setup .and it was working before perfectly now its showing error(below).
1)i have changed client_secret
2)created a new oauth credentials
still not working
public function redirectToGoogle()
{
return Socialite::driver('google')->redirect();
}
public function handleGoogleCallback()
{
$user = Socialite::driver('google')->stateless()->user();
$user->getId(); // 1472352
$user->getNickname(); // "overtrue"
$name= $user->getName(); // "安正超"
$emailid= $user->getEmail();
$pic= $user->getAvatar(); // "anzhengchao#gmail.com"
return->redirect('welcome');
}
i have created env file with client_secret and client id
"""
Client error: `POST https://accounts.google.com/o/oauth2/token` resulted in a `400 Bad Request` response:\n
{\n
"error" : "invalid_grant",\n
"error_description" : "Code was already redeemed."\n
}\n
"""
When Google return the Authentication Code code to your Socialite, it can only be used to exchange to Access Token once. Doing more than once will result in the error Code was already redeemed.
The flow should be:
User click the login button on your website
You redirect user to Google and Google is asking user to login/grant you access
If successful, Google redirects back to you with a one-time-use Authentication Code?code=.....
Socialite use the ?code and exchange it with Google to get user's Access Token. This can only be done once per flow.
You can now request user details using the access token requested in step 4.

i have implemented GoogleAuthorizationCodeFlow scenario from google api client dotnet and tutorial to get token from what my client sent to server as a code. but when i call flow.ExchangeCodeForTokenAsync , I get the following error :
{"Error:\"invalid_grant\", Description:\"\", Uri:\"\""}
I read google authorization invalid_grant and gusclass oauth 2 using google dotnet api client libraries but they didn't help me and. I think it must be very simple but I don't know why it doesn't work.
For client side , I have used Satellizer and this is my server Codes:
public bool PostExchangeAccessToken(GoogleClientAccessCode code)
{
string[] SCOPES = { "email" };
IAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets()
{
ClientSecret = "******",
ClientId = "********.apps.googleusercontent.com"
},
Scopes = SCOPES
});
try
{
TokenResponse token;
token = flow.ExchangeCodeForTokenAsync("*****#gmail.com", Newtonsoft.Json.JsonConvert.SerializeObject(code), "https://localhost:44301/",
CancellationToken.None).Result;
}
catch (Exception ex)
{
throw ex;
}
return true;
}
what is the problem?
On Github I found that I must use the Token from the client and use
GoogleAuthorizationCodeFlow.Initializer()
to create my UserCredential object.
You can check your google developer console settings.(Authorized redirect URIs)
Credentials => OAuth 2.0 client IDs => Your Application Settings => Authorized redirect URIs
You must add url. ("https://localhost:44301/")
My code :
flow.ExchangeCodeForTokenAsync("me", authCode, redirectUri, CancellationToken.None).Result;
Authorized redirect URIs
For use with requests from a web server. This is the path in your application that users are redirected to after they have authenticated with Google. The path will be appended with the authorization code for access. Must have a protocol. Cannot contain URL fragments or relative paths. Cannot be a public IP address.
I'm hoping someone can help with this:
I have a web api secured with Azure AD Bearer Authentication, where I have two web clients that can successfully authenticate on the web api using bearer tokens from AD. The Web API and both web applications are configured as applications in AD. I've tried to use ADAL for Cordova for accessing the web api a iOS/Android app but it's returning 401.
ClaimsPrincipal.Current.Identity.IsAuthenticated is returning false.
I'm using the client id for the native application I've setup in Azure AD, and I'm receiving the token but this token is invalid. After I've parsed the token on jwt.io, everything seems correct but I've noticed the token doesn't have a header.
I've added permissions to access the Web Api and sign in and access AD as the user.
The code I'm using in Cordova is below, the authority I'm using is the same as the other apps that are working. Where resource is the app Id for the Web Api in AD, and client id is the client id for the native app in Azure Ad.
// Attempt to authorize user silently
AuthenticationContext.acquireTokenSilentAsync(resource, clientId)
.then(function (result) {
sessionService.logIn(result.idToken);
console.log(result);
deferred.resolve();
}, function () {
// We require user credentials so triggers authentication dialog
AuthenticationContext.acquireTokenAsync(resource, clientId, redirectUri)
.then(function (result) {
console.log(result);
sessionService.logIn(result.idToken);
deferred.resolve();
}, function (err) {
console.log("Failed to authenticate" + err);
deferred.reject("failed to authenticate");
});
});
I've also tried using result.accessCode, which also doesn't work.
StartUp.Auth.cs in Web Api:-
app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
app.UseWindowsAzureActiveDirectoryBearerAuthentication(
new WindowsAzureActiveDirectoryBearerAuthenticationOptions
{
Tenant = ConfigurationManager.AppSettings["ida:Tenant"],
TokenValidationParameters = new TokenValidationParameters {
ValidAudiences = Audiences
}
});
}
Can anyone help please?
Thanks
You appear to be sending the wrong token to the API - you are supposed to send result.accessToken. See https://github.com/Azure-Samples/active-directory-cordova-multitarget/blob/master/DirSearchClient/js/index.js for an example.
