使用Google登录名在wp8应用程序中对用户进行身份验证

Question

I want to authenticate a user from my wp8 app using users google login credentials. So that I can get profile info of user. I found two articles in web with source code. But I was unable to get what I want.

First code I've found in this Link . But after getting authentication code it didn't have any code to get profile. May be I could not understand.

Second code I've found in this Link . It was following mvvm pattern, so I was totally blank to understand this code.

If anyone have used it properly, please help me. What actually I want that after getting client id and client secret what to do in app to get user's profile info. Helps are appreciated. Thanks in advance.

Here is code

protected override void OnNavigatedTo(NavigationEventArgs e)

{

base.OnNavigatedTo(e);



IDictionary<string, string> parameters = this.NavigationContext.QueryString;



string authEndpoint = parameters["authEndpoint"];

string clientId = parameters["clientId"];

string scope = parameters["scope"];



string uri = string.Format("{0}?response_type=code&client_id={1}&redirect_uri={2}&scope={3}",

    authEndpoint,

    clientId,

    "urn:ietf:wg:oauth:2.0:oob",

    scope);



webBrowser.Navigate(new Uri(uri, UriKind.Absolute));

}

private async void LayoutRoot_Loaded(object sender, RoutedEventArgs e)

{

if(!App.loggedin)

{

    OAuthAuthorization authorization = new OAuthAuthorization(

    "https://accounts.google.com/o/oauth2/auth",

    "https://accounts.google.com/o/oauth2/token");

    TokenPair tokenPair = await authorization.Authorize(

        "YOUR_CLIENT_ID",

        "CLIENT_SECRET",

        new string[] { GoogleScopes.UserinfoEmail });



    // Request a new access token using the refresh token (when the access token was expired)

    TokenPair refreshTokenPair = await authorization.RefreshAccessToken(

        "YOUR_CLIENT_ID",

        "CLIENT_SECRET",

        tokenPair.RefreshToken);

}

}

what to do after getting access token?

This is the code that allows you to view the profile details:

private void LoadProfile(string access_token)
{
    Debug.WriteLine("loading profile");

    RestClient client = new RestClient("https://www.googleapis.com");
    client.Authenticator = new OAuth2AuthorizationRequestHeaderAuthenticator(access_token);
    var request = new RestRequest("/oauth2/v1/userinfo", Method.GET);
    client.ExecuteAsync<Profile>(request, ProfileLoaded);
}
private void ProfileLoaded(IRestResponse<Profile> response)
{
    Profile = response.Data;
}

Just pass in the access_token you got from your prior code and the data should be contained in response.Data
