Question

我在网站上登录facebook时收到错误。

我收到此错误：sdk.ErrorHandling

当我删除登录功能时它工作得很好，我认为我在登录功能方面有一些问题。

任何人都可以帮我写一下如何写facebook的登录功能

这是我的代码：

function login() {
        oldToken = FB.getAccessToken();
        FB.login(function (response) {
            if (response.authResponse && response.authResponse.accessToken != oldToken) {
            if (fbdone == false) {
                GetUserData();
                fbdone = true;
            }
            }
        }, {
            auth_type: 'reauthenticate', scope: 'email,user_friends,public_profile'
        });

我正在犯这个错误
