Question

我想获得facebook好友列表，但我的回复是null。我正在使用javascript sdk。加法总之，我得到了朋友的号码。但没有得到数据。

这是我的代码： -

getAcceptedIssuers().

任何人都可以告诉我，我在哪里犯错？

Answer 1

你FB.init（）是否正确？

您是否在developer.facebook页面中为您的应用添加了正确的权限？

然后你会错过一些信息，例如你在朋友列表和范围中想要的字段：

     FB.login(function(response) {
       if (response.authResponse) {
            FB.api('/me/friends', {fields: 'XXXXX'}, function(response) {
               console.log(response);
            });
        } else
        {
            console.log('Authorization failed.');
        }
     },{scope: 'friends'});

Answer 2

您永远无法获取朋友的电话号码，因为他们不会通过图谱API公开。见https://developers.facebook.com/docs/graph-api/reference/user#Reading

此外，您应该坚持使用Fb文档中的示例，请参阅

从FB复制的示例代码：

<!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      : '{your-app-id}',
    cookie     : true,  // enable cookies to allow the server to access 
                        // the session
    xfbml      : true,  // parse social plugins on this page
    version    : 'v2.4' // use version 2.4
  });

  // 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?fields=id,name,friends', 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,user_friends" onlogin="checkLoginState();">
</fb:login-button>

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

</body>
</html>

Answer 3

在Android SDK上，您必须添加类似

的权限

        LoginButton loginButton = (LoginButton) findViewById(R.id.loginButton);
    loginButton.setReadPermissions(Arrays.asList("email", "user_friends"));

良好的编程。

Answer 4

试一下

FB.api（'/ me / friends'，{fields：'id，name，picture'}，

功能（响应）{

的console.log（响应）;

}）;

Facebook Graph API返回空数据
