facebook 在滚动时加载 xd_proxy.php
大家好，有人知道 facebook 上的 iframe 应用程序不断加载 xd_proxy.php 是怎么回事吗？我没有注意到这是一个新的或现有的问题，因为我的应用程序屏幕已修复，今天，当我更改一些代码时，我用鼠标滚动屏幕，发现 xd_proxy 正在滚动时加载（无论使用鼠标滚轮， kb箭头，滚动条..），我在谷歌和堆栈溢出中搜索了一些帖子，但没有运气，他们都无法解决它，我尝试添加channelurl，重新排列javascript...等，但没有运气好，请帮忙，提前致谢。

现在，这已在 Facebook 的错误跟踪器中记录为错误。解决这个问题的最好方法就是投票！

Facebook 本周修复了我们一直在等待的 JS SDK 中的一个错误，因此我们计划从旧的 JS SDK 切换到新的，但在最终测试期间也遇到了这个问题。看起来窗口位置正在被报告回来。
有人知道这是否是新的以及它的具体用途是什么？可以禁用吗？想知道这会对不同环境下的性能产生什么影响。
Facebook fixed a bug we have been waiting on in their JS SDK this week so we were planning on switching from the old JS SDK to the new but during final testing came across this as well. Looks like window location is being reported back.
Anyone know if this is new and what exactly it is used for? Can it be disabled? Wonder what this would do to performance across different environments.
在使用 de JS SDK 调用 window.fbAsyncInit 中的 FB.init 后，就会开始发生这种情况。它传递客户端的高度和宽度，并作为canvasPage.update 类型的滚动参数。这可能（但我不知道）与今年早些时候的一个错误有关，当时 iframe 中的应用程序没有调整大小，类似于解决方法。
This starts happening after FB.init in window.fbAsyncInit is called with de JS SDK. It is passing height and width of the client and scroll as parameters with type canvasPage.update. It might, but I do not know, have something to do with a bug earlier this year when apps in iframes weren't resizing, something like a work around.
我今天也才注意到这一点，最初认为这是由于 FB.Canvas.setAutoResize() 被偷偷调用，但不，滚动似乎已绑定到此更新。
I just noticed this today as well, and initially thought it was due to FB.Canvas.setAutoResize() being called surreptitiously, but nope, it seems like scroll has been bound to this update.
