Question

在facebook js sdk app development ..我需要找到从收件箱发送的facebook消息的数量。我正在使用的代码是

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
   <body>

<script>

  function statusChangeCallback(response) {
console.log('statusChangeCallback');
console.log(response);

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.';
}


}



  function checkLoginState() {
FB.getLoginStatus(function(response) {
  statusChangeCallback(response);
    });
}

  window.fbAsyncInit = function() {
  FB.init({
appId      : '289533237896176',
cookie     : true,  // enable cookies to allow the server to access 
                    // the session
xfbml      : true,  // parse social plugins on this page
version    : 'v2.0' // use version 2.0
  });

  };


  (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'));


  function testAPI() {
console.log('Welcome!  Fetching your information.... ');
FB.api('/me/inbox',function(response) {  for (var i=0;i<response.data.length;i++) {
var thread = response.data[i];

for (var j=0;j<thread.comments.data.length;j++) {
    var comment = thread.comments.data[j].message;

    console.log(comment);


}
}



}



);


}

</script>

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

<div id="status">

<div id="fb-root"></div>

</div>

</body>

</html>

这个脚本成功检索了前10条消息的数量..我需要的是显示总共的消息数量。

Facebook自动将分页应用于返回项目列表的所有API请求。如果未指定页面大小，FB将应用其默认大小。从您的示例看，每页看起来有10个项目。要移至下一页，您应使用response.paging.next字段 - 它包含由FB生成的准备使用的URL以访问下一页。如果您到达最后一页，response.paging字段将为空。

此外，如果您想将页面大小调整为例如每页50个项目，您可以limit=50添加到您的请求中。代码如下：

FB.api('/me/inbox?limit=50', ...
