一：创建和配置开发者应用

https://developers.facebook.com

登录开发者（可能要手机验证，身份证严重）-》创建应用（web ）->填写配置，网站网址和应用域名需要一致。

二：页面调用

DOCTYPE html> Facebook Login JavaScript Example // 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}', cookie : true, // enable cookies to allow the server to access // the session xfbml : true, // parse social plugins on this page version : 'v2.8' // use graph api version 2.8 }); // Now that we've initialized the JavaScript SDK, we call // FB.getLoginStatus(). This function gets the state of the // person visiting this page and can return one of three states to // the callback you provide. They can be: // // 1. Logged into your app ('connected') // 2. Logged into Facebook, but not your app ('not_authorized') // 3. Not logged into Facebook and can't tell if they are logged into // your app or not. // // 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 + '!'; }); }

修改以上代码。appId : '{your-app-id}', 填写，你的应用ID。

即可成功调用。

可以根据实际情况做适当调整。如样式，登录提示等
