get my infomation.but i didn't get it .Please help me.

 if (Request.QueryString["Code"] != null)

Hi there!

If you are using ASP.NET/A webserver as a base for your project, you cannot use 
the NativeApplicationFlow as that one will only work for client-based 
applications. It won't allow a specific Callback URI.

We don't have an ASP.NET example for the shopping api per se, but you can 
easily use the Tasks-API example by just replacing the "TasksService" with the 
"PlusService":

http://code.google.com/p/google-api-dotnet-client/source/browse/Tasks.ASP.NET.Si
mpleOAuth2/Default.aspx.cs?repo=samples

Hope this helps!

You will need to enable the appropriate services in the Google API Console, 
which can be found by going to the link below and clicking on "Services":

  https://code.google.com/apis/console/

Also, on a side note: Which API are you currently trying to access? The error 
message seems to come from the Tasks API. If you intent to use the Google+ API, 
you will have to use the PlusService instead.

thanks!

I want to use Google+ API. I just want to created a web page to call 'OAuth 2.0 
to Access Google APIs' and want to get my infomation with Google+API. Please 
see below code:

---------------------------------------step one
// page load,use below code to Redirect to goole and google will call 
//Callback URL to my project.

            List<string> scopes = new List<string>();
            scopes.Add("https://www.googleapis.com/auth/plus.me");
            scopes.Add("https://www.googleapis.com/auth/userinfo.email");
            var state = new AuthorizationState(scopes);
            state.Callback = new Uri("http://localhost:3877/WEB/Default2.aspx");

            Uri ur = provider.RequestUserAuthorization(state);// this.provider.RequestUserAuthorization(state);
            string requestUrl = ur.ToString();

             requestUrl += "&access_type=offline";
             requestUrl += "&approval_prompt=force";

             requestUrl += "&state=" + provider.ClientIdentifier + "_" + provider.ClientSecret;
            //Plese see below post URL
            this.Response.Redirect(requestUrl);
--------------------------------step two
after the google return to my web project:

if (Request.QueryString["Code"] != null)
        {
            //I can get the code from google api callback url
            string authCode = Request.QueryString["Code"].ToString();       
            if (!string.IsNullOrEmpty(authCode))
            {

                List<string> scopes = new List<string>();
                scopes.Add("https://www.googleapis.com/auth/plus.me");
                scopes.Add("https://www.googleapis.com/auth/userinfo.email");
                var state = new AuthorizationState(scopes);
                state.Callback = new Uri("http://localhost:3877/WEB/Default2.aspx");
                // i can get the accesstoke and refreshtoken
                stat = provider.ProcessUserAuthorization(authCode, state);

                // but in these. i can't get the oAuth2Auth , plese 
                // see   GetAuthentication function
                var oAuth2Auth = new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthentication);

                // get user profile
                var objService = new PlusService(oAuth2Auth);
                var me = objService.People.Get("me").Fetch();
            }
        }

=============> your saied:  "you cannot use the NativeApplicationFlow as that 
one will only work for client-based applications. It won't allow a specific 
Callback URI.
"

var oAuth2Auth = new OAuth2Authenticator<NativeApplicationClient>(provider, 
GetAuthentication);
// get user profile
var objService = new PlusService(oAuth2Auth);
var me = objService.People.Get("me").Fetch();

if i want to use PlusService to get my infomation how to get the 
"oAuth2Auth"(plase see above code) and don't use NativeApplicationClient ? 
Please help me thanks!!!

The (unchecked) code which can be found at the URL below demonstrates how you 
can use the Google+ API with ASP.NET using the WebServerFlow:

GoogleCodeExporter commented 9 years ago 
There are several possible issues for this error. Try checking those things:

(a) Have you entered your client secret and client ID in the 
ClientCredentials.cs file or when creating the authenticator? Make sure the 
values entered are equal to those displayed on the API Console.

(b) If you are running the ASP.NET sample make sure that you created a client 
id+secret set which is also configured as a Web-Application, not as an Native 
Application. You can create multiple client id/secret sets if you require both 
kinds of applications.

(c) Enable the "Google Plus" service in your API Console Access Tab

(d) Make sure you are using a valid access token. Access Tokens only stay valid 
for about two hours, and old ones might get invalidated once you re-request a 
new access token using the same client id/secret set. If the problem persists, 
debug the code and make sure the access token you just acquired when clicking 
"Authenticate" on your ASP.NET page gets passed into the Authenticator when 
clicking "Fetch Info".

I have read this thread and implements all like above. I still got 401 error, I 
use this to access latitude API. I had checked client Id and secret, all were 
same as my console. My authenticator was also WebServerClient type, Latitude 
API had been turned on. Token had been acquired correctly and the expiration 
time still 1 hour left. Is anyone have a solution for this? I was in urgent, 
cause of client demanded.

Hi, when we use this code for Google Task

/******************
  _service = New TasksService(CreateAuthenticator())

   Dim response As TasklistsResource = _service.Tasklists

   Return ShowTaskslists(response.List(100).Fetch())

*******************/

we got below error and after that this error also got when add task in loop

I planned on adding a sample for the plus API to the samples/ repository (as 
shown in the codereview CL), but didn't get any chance to do it. So for the 
moment I am just changing the status back.

Eu estou usando o Google Prediction e Preciso de autenticar para fazer minhas

          // Display the header and initialize the sample.
            CommandLine.EnableExceptionHandling();
            CommandLine.DisplayGoogleSampleHeader("Tasks API");

            // Register the authenticator.
            // Get the auth URL:
            //IAuthorizationState state = new AuthorizationState(new[] { TasksService.Scopes.Tasks.GetStringValue() });

            var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description);
            FullClientCredentials credentials = new FullClientCredentials();
            credentials.ApiKey = "AIzaSyCrNndiZazK3zbJxdZu6cSfVCLLuN5FFog";

            var service = new TasksService(auth);
            TaskLists results = service.Tasklists.List().Fetch();
      }

só que quando eu solicito a autenticação ele retorna esse erro:

Your main/setup method looks ok, although the 'state' variable seems to be 
unused/misplaced here. Can you show your GetAuthorization method? The 
authorization will only be added if the GetAuthorization method returns a 
non-null IAuthorizationState.

Original comment by mlinder...@gmail.com on 7 Aug 2012 at 6:34

GoogleCodeExporter commented 9 years ago 
a sim segue o modelo do:

        private static IAuthorizationState GetAuthorization(NativeApplicationClient arg)
        {

            // Get the auth URL:
            IAuthorizationState state = new AuthorizationState(new[] { TasksService.Scopes.Tasks.GetStringValue() });

            state.Callback = new Uri(NativeApplicationClient.OutOfBandCallbackUrl);
            Uri authUri = arg.RequestUserAuthorization(state);

            // Request authorization from the user (by opening a browser window):
            Process.Start(authUri.ToString());

            string authCode = null;

            // Retrieve the access token by using the authorization code:
            return arg.ProcessUserAuthorization(authCode, state);
        }

Espero que veja o que está de errado, pois eu já tentei tudo!

That is definitely where things go wrong. AuthCode should not be null, 
otherwise you won't be able to get a valid refresh & access token. Have a look 
at this implementation of the GetAuthorization method, and try using it:

http://code.google.com/p/google-api-dotnet-client/source/browse/Tasks.CreateTask
s/Program.cs?repo=samples

The AuthorizationMgr used by this code can be found here:

Hi there,
I am using google api sample code. I can successfully get all the tasklist as 
well as task using asp.net but when I want to insert  a task using the 
following code(where listID is a valid tasklist id):
_service.Tasks.Insert(new Task { Title = "Party for DL2" }, listID).Fetch();

I got the following error:
Google.Apis.Requests.RequestError
Invalid Credentials [401]
Errors [
    Message[Invalid Credentials] Location[Authorization - header] Reason[authError] Domain[global]
]

please help me.
