Xamarin Android Xamarin.Auth - 推特

Question

我在 Xamarin Android 中实现 Twitter 登录时遇到问题。我包含了 Xamarin.Auth 组件，它适用于 Facebook。 Fot twitter auth.Completed 事件未被调用... 我已经在 Twitter 开发门户上创建了示例应用程序。

这是我在应用程序中的代码：

private void LoginTwitter()
    {
        var auth = new OAuth1Authenticator(
                  consumerKey: "3v7rOXkdexGYhQmr3HVhtGgPO",
                  consumerSecret: "mGhRjee87tAp4X0vHUmMIohWoYy0JGg9zFGyin7CigFP64y3j5",
                  requestTokenUrl: new Uri("https://api.twitter.com/oauth/request_token"),
                  authorizeUrl: new Uri("https://api.twitter.com/oauth/authorize"),
                  accessTokenUrl: new Uri("https://api.twitter.com/oauth/access_token"),
                  callbackUrl: new Uri("http://twitter.com")
              );
        auth.AllowCancel = true;
        StartActivity(auth.GetUI(this));
        auth.Completed += (s, eventArgs) =>
        {
            if (eventArgs.IsAuthenticated)
            {

                Account loggedInAccount = eventArgs.Account;
                //save the account data for a later session, according to Twitter docs, this doesn't expire
                AccountStore.Create(this).Save(loggedInAccount, "Twitter");
            }
        };
    }

希望有人帮忙

我认为您需要将 Completed 事件处理上移，因为我认为 StartActivity 正在阻塞。

private void LoginTwitter()
{
    var auth = new OAuth1Authenticator(
              consumerKey: "3v7rOXkdexGYhQmr3HVhtGgPO",
              consumerSecret: "mGhRjee87tAp4X0vHUmMIohWoYy0JGg9zFGyin7CigFP64y3j5",
              requestTokenUrl: new Uri("https://api.twitter.com/oauth/request_token"),
              authorizeUrl: new Uri("https://api.twitter.com/oauth/authorize"),
              accessTokenUrl: new Uri("https://api.twitter.com/oauth/access_token"),
              callbackUrl: new Uri("http://twitter.com")
          );
    auth.AllowCancel = true;
    auth.Completed += (s, eventArgs) =>
    {
        if (eventArgs.IsAuthenticated)
        {

            Account loggedInAccount = eventArgs.Account;
            //save the account data for a later session, according to Twitter docs, this doesn't expire
            AccountStore.Create(this).Save(loggedInAccount, "Twitter");
        }
    };

    StartActivity(auth.GetUI(this));
}

好的，我自己解决了这个问题。创建新的 OAuth1Authenticator 时 CallBack Url 应设置为 mobile.twitter.com 而不是 twitter.com

callbackUrl: new Uri("http://mobile.twitter.com")

之后您将能够获得令牌。

希望对以后的人有所帮助。 :)

编辑：您现在需要使用 http://mobile.twitter.com/home-
