如果用户没有登录到Facebook，则FB.getLoginStatus不会触发 [英] FB.getLoginStatus doesn't fire if the user is not logged in to Facebook

问题描述

我正在Facebook上整合Facebook应用程序，并尝试获取用户的FB会话。据我所知，一个常见的使用情况如下。

1. 调用 FB.init（） code>


2. 调用 FB.getLoginStatus 给它一个适当的回调。

我运行了以下代码（应用程序ID）。

 < div ID = FB-根 >< / DIV> 
< script src =http://connect.facebook.net/en_US/all.js>< / script> 
< script type =text / javascript> 
<！ -  
 
函数init（）{
 FB.init（{
 appId：'9999999999999'，
 status：true，/ /检查登录状态
 cookie：true，//启用Cookie以允许服务器访问会话
 xfbml：true，//解析XFBML 
 channelUrl：'http://127.0.0.1 ：8888 / channel.html'，//自定义渠道
 oauth：true //启用OAuth 
}）; 
 alert（'去调用FB.getLoginStatus'）; 
 
 FB.getLoginStatus（function（response）{
 alert（'whoo hoo !!! getLoginStatus called the callback'）; 
}）; 
} 
 init（）; 
 //  - > 
< / script> 
  

如果用户已经在同一浏览器会话中登录到Facebook，那么一切都按预期方式运行 - 返回人口稠密的 _response.authResponse _ 。但是，如果用户没有登录到Facebook，则不会触发回调。检查浏览器网络日志，我看到Facebook返回以下响应（请求从 http://www.facebook.com/dialog/oauth ？）。

应用程序错误：获取您请求的应用程序的数据时出现问题。申请可能无效，或可能有暂时的毛刺。请稍后再试。

我在Chrome和Firefox（Mac）上检查过。

解决方案

原因是最近的一个 bug ，这只影响沙箱模式。我关闭了沙箱模式，它的工作就像一个魅力。

I am working on a Facebook application which is integrated with Facebook and am trying to get the user's FB session. As far as I understand, a common usage scenario is as follows.

1. call FB.init()
2. call FB.getLoginStatus giving it an appropriate callback.

I ran the following code (the application id).

<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script type="text/javascript">
    <!--

    function init(){
        FB.init({
            appId  : '9999999999999',
            status : true, // check login status
            cookie : true, // enable cookies to allow the server to access the session
            xfbml  : true, // parse XFBML
            channelUrl : 'http://127.0.0.1:8888/channel.html', // custom channel
            oauth  : true // enable OAuth
        });
        alert('going to call FB.getLoginStatus ');

        FB.getLoginStatus(function(response) {
            alert('whoo hoo!!! getLoginStatus called the callback');
        });
    }
    init();
    //-->
</script>

If the user is already logged in to Facebook in the same browser session then everything works as expected - returning the populated _response.authResponse_. However, if the user is not logged in to Facebook the callback is not triggered at all. Checking the browsers network log, I see that Facebook returns the following response (request from http://www.facebook.com/dialog/oauth?).

Application Error: There was a problem getting data for the application you requested. The application may not be valid, or there may be a temporary glitch. Please try again later.

I checked this on Chrome and Firefox (Mac).

Ben's comment had the answer.

Thanks Ben - you saved me lots of frustration.

解决方案

The cause is a recent bug which only affects sandbox mode. I switched off sandbox mode, and it worked like a charm.
