我以爲它會幫助你,如果你想使用JavaScript SDK爲此請複製此代碼:
<DOCTYPE html>
<html>
<head>
<title>Facebook Login JavaScript Example</title>
<meta charset=」UTF-8″>
</head>
<body>
<script>
// This is called with the results from from FB.getLoginStatus().
function statusChangeCallback(response) {
console.log(‘statusChangeCallback’);
console.log(response);
// The response object is returned with a status field that lets the
// app know the current login status of the person.
// Full docs on the response object can be found in the documentation
// for FB.getLoginStatus().
if (response.status === ‘connected’) {
// Logged into your app and Facebook.
testAPI();
} else if (response.status === ‘not_authorized’) {
// The person is logged into Facebook, but not your app.
document.getElementById(‘status’).innerHTML = ‘Please log ‘ +
‘into this app.';
} else {
// The person is not logged into Facebook, so we’re not sure if
// they are logged into this app or not.
document.getElementById(‘status’).innerHTML = ‘Please log ‘ +
‘into Facebook.';
}
}
// This function is called when someone finishes with the Login
// Button. See the onlogin handler attached to it in the sample
// code below.
function checkLoginState() {
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
}
window.fbAsyncInit = function() {
FB.init({
appId : ‘{your-app-id}’,// plaste your app id
cookie : true, // enable cookies to allow the server to access
// the session
xfbml : true, // parse social plugins on this page
version : ‘v2.1′ // use version 2.1
});
// These three cases are handled in the callback function.
FB.getLoginStatus(function(response) {
statusChangeCallback(response);
});
};
// Load the SDK asynchronously
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = 「//connect.facebook.net/en_US/sdk.js」;
fjs.parentNode.insertBefore(js, fjs);
}(document, ‘script’, ‘facebook-jssdk’));
// Here we run a very simple test of the Graph API after login is
// successful. See statusChangeCallback() for when this call is made.
function testAPI() {
console.log(‘Welcome! Fetching your information…. ‘);
FB.api(‘/me’, function(response) {
console.log(‘Successful login for: ‘ + response.name);
document.getElementById(‘status’).innerHTML =
‘Thanks for logging in, ‘ + response.name + ‘!';
});
}
</script>
<fb:login-button scope=」public_profile,email」 onlogin=」checkLoginState();」>
</fb:login-button>
<div id=」status」>
</div>
</body>
</html>
我發現從AU腳本seful教程,如果你正在考慮編輯這個答案,請參閱本教程Facebook Login Integration with website
我有一個問題,有關當用戶在facebook上簽名againg時得到有關用戶的舊信息。我使用PHP從我的數據庫中獲取舊信息。但是安全呢?如果我只使用facebook id,任何人都可以使用facebook id來獲取信息。 – tasomaniac
