在控制台中调用FB.init（）错误之前调用FB.getLoginStatus（）

I am trying to check if a user is logged in with my app, but I am getting a "

我正在尝试检查用户是否使用我的应用程序登录，但我收到了“

FB.getLoginStatus() called before calling FB.init().

在调用FB.init（）之前调用FB.getLoginStatus（）。

" error in the console. The setSize appears to work (although not entirely 1710 height but definately around 1500) so I cannot understand why the getLoginStatus() gives the error.

“控制台中的错误.setSize似乎工作（虽然不完全是1710高度，但绝对是1500左右）所以我无法理解为什么getLoginStatus（）会给出错误。

I also double checked with the appID (removed below) and that is definately correct. The script is included via right below my and div

我还用appID（在下面删除）进行了双重检查，这肯定是正确的。脚本包含在我和div的正下方

window.fbAsyncInit = function() {
FB.init({
    appId      : 'APPID', // App ID
    status     : true, // check login status
    cookie     : true, // enable cookies to allow the server to access the session
    oauth      : true, // enable OAuth 2.0
    xfbml      : true  // parse XFBML 
});

FB.Canvas.setSize({width: 520, height: 1710});

FB.Canvas.setAutoResize(100);

FB.getLoginStatus(function(response) {
    if (response.authResponse) {
        // logged in and connected user, someone you know
        alert("?");
    } else {
        // no user session available, someone you dont know
        alert("asd");
    }
});
};

You need to load the api asynchronously. Try removing your <script src="connect.facebook.net/en_US/all.js"></script> and updating your JS to:

您需要异步加载api。尝试删除

<div id="fb-root"></div>
<script>
  window.fbAsyncInit = function() {
    FB.init({
      appId      : 'YOUR_APP_ID', // App ID
      channelURL : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File
      status     : true, // check login status
      cookie     : true, // enable cookies to allow the server to access the session
      oauth      : true, // enable OAuth 2.0
      xfbml      : true  // parse XFBML
    });

    //
    // All your canvas and getLogin stuff here
    //
  };

  // Load the SDK Asynchronously
  (function(d){
     var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
     js = d.createElement('script'); js.id = id; js.async = true;
     js.src = "//connect.facebook.net/en_US/all.js";
     d.getElementsByTagName('head')[0].appendChild(js);
   }(document));
</script>

Oh and check the documentation!

哦，检查文档！

This error will also occur if you don't provide an appId to FB.init. Example:

如果您不向FB.init提供appId，也会发生此错误。例：

    FB.init({
        appId: ''
        , channelUrl: '//domain/channel.html'
        , status: true
        , cookie: true
    });

Will result in:

将导致：

FB.getLoginStatus() called before calling FB.init().

在调用FB.init（）之前调用FB.getLoginStatus（）。
