Channel URL Facebook

提问by Federico Capello

I'm implementing the facebook login in my website wich is in the form of mysite.anotherdomain.org . I did all explained in the Documentation of the Javascript SDK but, since I have some problems, I'm wondering if the error comes from the channel url.

我正在以 mysite.anotherdomain.org 的形式在我的网站上实现 facebook 登录。我在 Javascript SDK 的文档中做了所有解释，但是，由于我遇到了一些问题，我想知道错误是否来自频道 url。

What should I exactly write for the channel file?

我应该为频道文件写什么？

Thanks in advance!

提前致谢！

The channel file basically fixes certain cross-domain issues for certain browsers. The following are the three that Facebook has identified:

频道文件基本上修复了某些浏览器的某些跨域问题。以下是 Facebook 确定的三个：

Pages that include code to communicate across frames may cause Social Plugins to show up as blank without a channelUrl.

包含跨帧通信代码的页面可能会导致社交插件在没有 channelUrl 的情况下显示为空白。

if no channelUrl is provided and a page includes auto-playing audio or video, the user may hear two streams of audio because the page has been loaded a second time in the background for cross domain communication.

如果没有提供 channelUrl 并且页面包含自动播放的音频或视频，则用户可能会听到两个音频流，因为页面已在后台第二次加载以进行跨域通信。

a channel file will prevent inclusion of extra hits in your server-side logs. If you do not specify a channelUrl, you should remove page views containing fb_xd_bust or fb_xd_fragment parameters from your logs to ensure proper counts.

频道文件将防止在您的服务器端日志中包含额外的点击。如果未指定 channelUrl，则应从日志中删除包含 fb_xd_bust 或 fb_xd_fragment 参数的页面浏览量以确保正确计数。

All you need inside the file is

您只需要在文件中

<script src="//connect.facebook.net/en_US/all.js"></script>
