我是使用 FB JS SDK 的新手，所以请多多包涵。
我目前正在尝试为网站设置 facebook 登录。我遇到的问题是，当我单击登录按钮并输入我的登录详细信息时，facebook 仅在我使用创建应用程序的帐户时才返回用户信息。当我使用不同的帐户时，response.authResponse 返回“未知”状态，我觉得这很不寻常。
我在这里提到的主要功能是this.loginUser。
我还注意到，当我在帐户上输入我的详细信息时，我在 facebook 上创建了该应用程序会通知我该应用程序想要访问...详细信息但是当我使用其他帐户时，登录面板将在登录提交时消失，而不是请求许可。
这是我的代码：
var FBUser = function(options) {
this.userInfo = null;
var that = this;
/* **********************************************

this.options = $.extend({
signInBtn: null,
messageContainer: null,
accountContainer: null
}, options);

this.init = function (){
//Load FB JS SDK
this.checkIfLoggedIn();
//Bind event handlers
this.bindEventHandlers();
};
//Check if user is already logged in, if so return data
this.checkIfLoggedIn = function(){
// Additional init code here
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
console.log("You logged in before so were retrieving your info...");
// the user is logged in and has authenticated your app
var uid = response.authResponse.userID;
var accessToken = response.authResponse.accessToken;
that.userInfo = response;
that.showUserInfo();
// connected
} else if (response.status === 'not_authorized') {
alert("not connected");
// not_authorized
} else {
// not_logged_in
}
});
};
//Run event handlers to window
this.bindEventHandlers = function() {
if(that.options.signInBtn !== null){
//Trigger fb Login
$(document).on("click", that.options.signInBtn, function(){
console.log("triggered get login");
that.loginUser();
});
}else{
console.log("Btn ID's are null");
}
};
//Trigger FB login
this.loginUser = function(){
FB.login(function(response) {
console.log("RESPONSE IS: ");
console.log(response);
if (response.authResponse) {
var access_token = FB.getAuthResponse()['accessToken'];
console.log('Access Token = '+ access_token);
console.log('Welcome! You just logged in. Fetching your information.... ');
that.userInfo = response;
that.showUserInfo();
} else {
// sign out
console.log('User does not grant extended permissions');
}
}, {scope: 'email, read_friendlists, user_birthday, user_location'});
};
//Show user info
this.showUserInfo = function (){
var info = this.userInfo;
if(this.userInfo){
FB.api('/me', function(info) {
console.log('Good to see you, ' + info.name);
console.log("USER DATA IS: ");
console.log(info);
//Append user info
if(that.options.messageContainer){
$(that.options.accountContainer).show();
$(that.options.messageContainer).html(info.name)

$(that.options.signInBtn).hide();
}else{
console.log("Login button is null");
}
});
}
};
//Log user out
this.FBLogout = function(){
FB.logout(function(response) {
console.log("user is now logged out");
$(that.options.signInBtn).show();
$(that.options.accountContainer).hide();
});
};
return this.init();
