我记得 FB.init() 有一个 channelUrl 选项，但根据 this page，它似乎不再存在了
此功能是否已弃用？
最佳答案
是的，不再需要 channelUrl。这是博客文章中的引述:
Changed browser requirements for the JavaScript SDK
In order for the JavaScript SDK to be able to communicate with Facebook, we now require either native support for HTML5 postMessage, or support for Flash, minimum version 8.0.24. As part of this change, we are no longer supporting the use of the channelUrl initialization option to provide a fallback mechanism.
关于javascript - Facebook init() 的 channelUrl 参数是否已弃用？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22261080/
