[英]GooglePlus Authentication in Windows Phone 8.1
I am writing a Windows Phone 8.1 App (WINRT) . 我正在编写Windows Phone 8.1应用程序(WINRT) 。 How to do GooglePlus Authentication (SignIn via GooglePlus) in Windows Phone 8.1 App** without using MVVM/MVC**?
在不使用MVVM / MVC **的情况下如何在Windows Phone 8.1 App **中进行GooglePlus身份验证(通过GooglePlus登录) ?
I used Web Authentication via Webbrowser control in Windows Phone 8.0 App but Windows Phone 8.1 WebView Control does not have Navigating event . 我在Windows Phone 8.0应用程序中通过Webbrowser控件使用了Web身份验证,但Windows Phone 8.1 WebView控件没有导航事件 。
Can anyone help me? 谁能帮我?

//Request User info.
HttpClient httpClient = new HttpClient();
string response = await httpClient.GetStringAsync(new Uri("https://graph.facebook.com/me?access_token=" + access_token));
JsonObject value = JsonValue.Parse(response).GetObject();

}
}
}
But giving me error: The remote procedure call failed. 但给我错误: 远程过程调用失败。 (Exception from HRESULT: 0x800706BE)
(来自HRESULT的异常:0x800706BE)
I'd start with WebAuthenticationBroker
. 我将从
WebAuthenticationBroker
开始。 It's a sort of wrapper around WebView
you use for all OAuth. 这是用于所有OAuth的
WebView
的包装。
