Facebook发布到墙不工作

Question

我正在为我的应用开发Facebook发布到墙功能。我正在使用Facebook Javascript SDK。但是，当我通过单击链接调用postToFeed（）函数时，它可以与iframe完美协作。但是，如果我想以某种其他方式加载（例如body onload），则iframe会显示错误“发生错误，请稍后再试”。我已经提供了带有FB.ui的access_token，它可以消除会话问题，但是如果不点击链接，仍然无法工作。以下是我的代码：

<div id='fb-root'></div> 
    <script src='http://connect.facebook.net/en_US/all.js'></script> 
    <p><a onclick='postToFeed(); return false;'>Post to Feed</a></p> 
    <p id='msg'></p> 
    <?php 
    $token_url = "https://graph.facebook.com/oauth/access_token?client_id=MY_CLIENT_ID&client_secret=MY_CLIENT_SECRET&grant_type=client_credentials&redirect_uri=MY_REDIRECT_URI"; 
    $token = file_get_contents($token_url); 

     ?> 

    <script> 
    FB.init({appId: "MY_APP_ID", status: true, cookie: true}); 

    function postToFeed() { 

    // calling the API ... 
    var obj = { 
     method: 'stream.publish', 
     display: 'iframe', 
     access_token: '<?php echo $token;?>', 
     link: 'https://developers.facebook.com/docs/reference/dialogs/', 
     picture: 'http://fbrell.com/f8.jpg', 
     name: 'Facebook Dialogs', 
     caption: 'Reference Documentation', 
     description: 'Using Dialogs to interact with users.' 
    }; 

    function callback(response) { 
     document.getElementById('msg').innerHTML = "Post ID: " + response['post_id']; 
    } 

    FB.ui(obj, callback); 
    } 

</script> 

我的应用程序现在处于沙盒模式。但我想这不是问题。请帮助我。谢谢

您的方法似乎不正确。您可能不会使用Facebook上的最新示例。参见：https://developers.facebook.com/docs/reference/dialogs/feed/

// calling the API ... 
var obj = { 
    method: 'feed', 
    link: 'https://developers.facebook.com/docs/reference/dialogs/', 
    picture: 'http://fbrell.com/f8.jpg', 
    name: 'Facebook Dialogs', 
    caption: 'Reference Documentation', 
    description: 'Using Dialogs to interact with users.' 
}; 

function callback(response) { 
    if (response && response.post_id) { 
    document.getElementById('msg').innerHTML = "Post ID: " + response.post_id; 
    } else { 
    alert('Post was not published.'); 
    }  
} 

FB.ui(obj, callback);
