JS端调用Facebook API

1. 申请Facebook账号

2.登陆http://developers.facebook.com/申请APPID

3.一定要对你申请的APP设置Site URL 和Site Domain，如果你需要调试，可以设置为http://localhost/和localhost

4.在页面中引用JS， <script src="//connect.facebook.net/en_US/all.js"></script>

5.现在就可以调用API了，在调用API之前，必须要进行初始化

调用如下函数进行初始化：

FB.init({            appId: '447540288619439', // App ID            channelUrl: 'http://example.com/channel.html', // Channel File            status: true, // check login status            cookie: true, // enable cookies to allow the server to access the session            xfbml: true,  // parse XFBML            oauth : true        });

登陆：

        function Test() {//            FB.api('/me', function (response) {//                alert('Your name is ' + response.name);            //            });            FB.login(function (response) {                if (response.authResponse) {                    alert('Welcome!  Fetching your information.... ');                    FB.api('/me', function (response) {                        alert('Good to see you, ' + response.name + '.');                    });                } else {                    alert('User cancelled login or did not fully authorize.');                }            }, { scope: 'email,user_location,offline_access,publish_stream' });        }

发布消息：要成功发布消息，必须让APP取得发送权限，注意上面登陆代码中的publish_stream

function PostTest() {            var picurl = "http://102.mlsimages.movoto.com/064/12048664_0.jpg";            var body = 'Hello every one, this is my house!';            FB.api('/me/feed', 'post', { message: body, picture:picurl }, function (response) {                debugger;                if (!response || response.error) {                    alert('Error occured');                } else {                    alert('Post ID: ' + response.id);                }            });        }
