function photos(){

     FB.api( "/{839506469483059}/photos", function (response) { if (response && !response.error) {
  var photos_name =  document.getElementById("statusq").innerHTML = response.picture;
      }
    }
);
}

Answer 1

试试这个：

FB.api("/839506469483059/photos", ...

在回调中放置console.log(response)以查看任何错误或数据。你会得到一系列图片，所以“response.picture”肯定是错的。

ID似乎不公开，我认为它是用户个人资料的专辑。在这种情况下，您需要先授权具有user_photos权限的用户。

以下是一个示例：http://www.devils-heaven.com/facebook-javascript-sdk-login/

编辑：由于ID似乎是用户ID，您应该添加一些字段以获取更多数据，并且您不应该使用ID而是“我”：

FB.api('/me/photos', {fields: 'picture'}, ...

确保使用user_photos进行授权，否则您将获得一个空数组。

javascript代码：

<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      : '<put your api key here>',
    cookie     : true,  // enable cookies to allow the server to access 
                        // the session
    xfbml      : true,  // parse social plugins on this page
    version    : 'v2.5' // use graph api version 2.5
  });

  // 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,email,hometown,last_name,location,middle_name,first_name,gender,picture,birthday', function(response) {
      console.log(response);
      document.getElementById('status').innerHTML =
        'Thanks for logging in, ' + response.name + '!';

    FB.logout(function(response) {
        // Person is now logged out
        console.log('LOGOUT',response)
        });
    });
  }

  function Login()
    {

        FB.login(function(response) {
           if (response.authResponse) 
           {
                testAPI();
            } else 
            {
             console.log('User cancelled login or did not fully authorize.');
            }
         },{scope: 'email,user_photos,user_videos'});


    }
</script>

  Below we include the Login Button social plugin. This button uses
  the JavaScript SDK to present a graphical Login button that triggers
