Question

我尝试使用以下代码在Facebook上发布到墙上时发生错误。它有时可以在第一次登录后发布，但以后总是会返回错误。

<?php

  include_once "include/settings.php";
  //include_once "include/messages.php";
  if(isset($_GET["access_token"]))
  {
    $access_token = $_GET["access_token"];
  }

  //$msg = $msg_en;
?>
<script language="javascript">
  function publishToWall(){

    var params = {};

    params['message'] = 'message';

    alert('<?php echo $access_token; ?>');
    FB.api('/me/feed', 'post', { message: 'test' }, function(response) {

        if (!response || response.error) {
            alert('Error occured');
        } else {
            alert('Post ID: ' + response);
        }
    });

  }
</script>

        window.fbAsyncInit = function() {
          FB.init({
            appId  : 'YOUR APP ID',
            status : true, // check login status
            cookie : true, // enable cookies to allow the server to access the session
            xfbml  : true  // parse XFBML
          });
          publishToWall();
        };

        (function() {
          var e = document.createElement('script');
          e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
          e.async = true;
          document.getElementById('fb-root').appendChild(e);
        }());
      </script>
    </body>
</html>

Answer 1

为什么<script>标记在<html>标记之前？将其放在<head>或<body>。

中

FB.api（）发生错误 - FB未定义
