我已经使用 javascript SDK 在我的网站中集成了 Facebook 登录。除了身份验证对话框，它只对用户显示一次。下次用户登录时，它会重定向而不显示身份验证对话框。我想要每次用户登录时显示身份验证对话框。这是我正在使用的代码
window.fbAsyncInit = function() {
FB.init({
appId : 'xxxxxxxx',
status : true,
cookie : true,
xfbml : true,
oauth : true
});
if (window!=window.top) {
FB.Canvas.setAutoResize();
};
FB.getLoginStatus(function(response) {
if (response.authResponse) {
window.FBlogin = function(){
FB.login(function(response) {
if (response.authResponse) {
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
var query = FB.Data.query('select name,username, email, hometown_location, sex, pic_square from user where uid={0}', response.id);
query.wait(function(rows) {
//document.getElementById('name').innerHTML = '<img src="' + rows[0].pic_square + '" alt="" />';
var name=rows[0].name;
var email=rows[0].email;
var uid=response.id;
var username=rows[0].username;
var pic=rows[0].pic_square;
});
});
}
else {
alert("error");
}
}, {scope: 'email'});
};
}
else {
var authbox = document.getElementById('FBauth');
authbox.innerHTML="";
var a = document.createElement('a');
a.setAttribute("href","javascript:void();");
a.setAttribute("onclick","FBlogin();");
authbox.appendChild(a);
window.FBlogin = function(){
FB.login(function(response) {
if (response.authResponse) {
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
var query = FB.Data.query('select name,username, email, hometown_location, sex, pic_square from user where uid={0}', response.id);
query.wait(function(rows) {
var name=rows[0].name;
var email=rows[0].email;
var uid=response.id;
var username=rows[0].username;
var pic=rows[0].pic_square;
});
});
}
}, {scope: 'email'});
};
}
});
FB.Event.subscribe('auth.login', function () {
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
var query = FB.Data.query('select name,username,email, hometown_location, sex, pic_square from user where uid={0}', response.id);
query.wait(function(rows) {
var name=rows[0].name;
var uid=response.id;
var email=rows[0].email;
var username=rows[0].username;
var pic=rows[0].pic_square;
var page='';
$('<input />').attr({'type':'hidden', 'id':'fbname','value':email}).appendTo('#fbaccess');
});
})
});
FB.Event.subscribe('auth.logout', function(response) {
});
};
