Question

因为我已经搜索了很多东西，让朋友们使用脚本或php来计算。但我无法得到实际的结果。大多数结果只会显示这些东西。

截至2014年7月22日星期二，我们现在在/v2.2/me/friends的回复中的摘要属性中返回total_count字段。

但我不知道如何让朋友们数数。请帮助我，我浪费了一整天才能得到这个。

我已尝试使用以下代码让我的朋友们计算

<!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      : 'My app Id',
    cookie     : true,  // enable cookies to allow the server to access 
                        // the session
    xfbml      : true,  // parse social plugins on this page
    version    : 'v2.4' // use version 2.2
  });

  // 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 + '!';
    });
  }
</script>

<!--
  Below we include the Login Button social plugin. This button uses
  the JavaScript SDK to present a graphical Login button that triggers
  the FB.login() function when clicked.
-->

<fb:login-button scope="public_profile,email" onlogin="checkLoginState();">
</fb:login-button>

<div id="status">
</div>

</body>
</html>

在FB.api('/me', function(response) {中它将返回我的用户ID和名称，我尝试使用FB.api('/me/friends', function(response) {它返回一个空数组..

请帮帮我..

要获取版本2+的朋友列表，FB已添加了额外的权限user_friends，您必须要求用户访问他的朋友列表。根据您上面的代码，您似乎没有权限。将user_friends添加到范围参数。

所以你的登录按钮参数应该是这样的

<fb:login-button scope="public_profile,email,user_friends" onlogin="checkLoginState();">
</fb:login-button>

提示：您可以使用以下网址检查您是否拥有该权限。

GET /{user-id}/permissions

如果你已经获得了许可，而且你的回复是空的，因为从版本2 + /me/friends返回用户的朋友，他们也在使用你的应用，如果你的应用相对较新你的朋友可能正在使用该应用程序。

您可能需要阅读Facebook上的upgrade guide以更好地了解它。
