Okay so you need to get the access_tokenof a user in JavaScript. Here you go:

好的，所以您需要access_token在 JavaScript 中获取用户的 。干得好：

1. Start reading the JavaScript SDK documentation

2. Something like the below will get you started:

   <div id="fb-root"></div>
   <script>
   window.fbAsyncInit = function() {
       FB.init({
           appId      : 'YOUR_APP_ID', // App ID
           channelUrl : '//WWW.YOUR_DOMAIN.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
       });
       // this shouldn't be called directly, but instead should be initiated with a user click event
       FB.login(function(response) {
           if (response.authResponse) {
               console.log('Access Token: ' + response.authResponse.accessToken);
           } else {
               console.log('User cancelled login or did not fully authorize.');
           }
       });
   
   };
   
   // 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>
   

3. As mentioned in the documentation:

   Calling FB.login results in the JS SDK attempting to open a popup window. As such, this method should only be called after a user click event, otherwise the popup window will be blocked by most browsers.

4. NEVEREVERask for the user password nor give it to ANYapplication if it asks you! and if it does, report it to Facebook directly!

5. It's "JavaScript" not "Java Script" :-)

1. 开始阅读JavaScript SDK 文档

2. 像下面这样的东西会让你开始：

   <div id="fb-root"></div>
   <script>
   window.fbAsyncInit = function() {
       FB.init({
           appId      : 'YOUR_APP_ID', // App ID
           channelUrl : '//WWW.YOUR_DOMAIN.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
       });
       // this shouldn't be called directly, but instead should be initiated with a user click event
       FB.login(function(response) {
           if (response.authResponse) {
               console.log('Access Token: ' + response.authResponse.accessToken);
           } else {
               console.log('User cancelled login or did not fully authorize.');
           }
       });
   
   };
   
   // 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>
   

3. 如文档中所述：

   调用 FB.login 会导致 JS SDK 尝试打开一个弹出窗口。因此，该方法只能在用户单击事件后调用，否则弹出窗口将被大多数浏览器阻止。

4. NEVER EVER索要用户密码也不给任何应用程序，如果问你！如果是，请直接向 Facebook 报告！

5. 它是“JavaScript”而不是“Java Script”:-)
