我使用了 facebook 文档中的示例,但在授予 facebook 连接权限后,我无法从用户对象获取任何用户信息。用户已定义,但其所有属性均为空。这是我的代码:
<html>
<head>
<title>My Facebook Login Page</title>
</head>
<body>
<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({
appId : '161718123880158', // App ID
channelUrl : '', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true, // parse XFBML
logging : true
});
FB.api('/me', function(user) {
if (user) {
var image = document.getElementById('image');
image.src = 'http://graph.facebook.com/' + user.id + '/picture';
var name = document.getElementById('name');
name.innerHTML = user.name
}
});
};
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
</script>
<div class="fb-login-button" scope="email,user_checkins">Login with Facebook</div>
<div align="center">
<img id="image"/>
<div id="name"></div>
</div>
</body>
</html>
名称和空图像的输出为 undef
