【问题描述】：
我正在尝试调用 facebook oauth login。一旦弹出与 facebook 登录页面一起出现，它不会再次重定向到同一应用程序。
<html>
<head>
<script type="text/javascript" src="/mp/struts/js/base/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="/mp/maincommon/static/js/all.js"></script>
<script type="text/javascript">
function onFaceBookAuth(user){
var id = user['id'];
var firstName = user['first_name'];
var lastName = user['last_name'];
var email = user['email'];
var params = "applicantId="+id+"&firstName="+firstName+"&lastName="+lastName;
var xmlhttp;
if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
}
else {// code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
var response = xmlhttp.responseText;
if(response.indexOf("new") != -1){
$('#applicantId').val(id);
$('#fbfirstName').val(firstName);
$('#fblastName').val(lastName);
$('#fbemail').val(email);
$('#applicantRegisterForm').submit();
}
else{
window.location = 'applicantHome.jsp?applicantId='+id;
}
}
};
xmlhttp.open("POST", "login?mode=2", true);
xmlhttp.setRequestHeader("Content-type",
"application/x-www-form-urlencoded");
xmlhttp.send(params);
}
function fbAsyncInit(){
FB.init({appId: '307292312637177', status: true, cookie: true, xfbml: true});
FB.getLoginStatus(function(response) {
var stringArr=JSON.stringify(response);
if (response.status == 'connected') {
fbLoginStatus = true;
showLogoutText();
}
else if (response.status == 'not_authorized') {
fbLoginStatus = false;
}
else {
// the user isn't even logged in to Facebook.
fbLoginStatus = false;
}
});
FB.Event.subscribe('auth.login', function(response) {
FB.api('/me', function(user) {
if (user) {
if(user.id!=undefined){
onFaceBookAuth(user);
}
}
});
});
FB.Event.subscribe('auth.logout', function(response) {
});
FB.api('/me', function(user) {
if (user) {
if(user.id!=undefined){
onFaceBookAuth(user);
}
}
});
};
</script>
</head>
<body>
<div id="facebookLogin" class="fb-login-button" onclick="fbAsyncInit()" data-scope="email">
Login with Facebook</div>
</body>
</html>
弹出窗口来输入 facebook 凭据。但是，之后它不会重定向回同一个应用程序。
这个问题与“appId”有关吗？因为我给了随机数，我不知道给“appId”什么。如何为我的应用获取 appId？
提前致谢
