FB通过网络应用程序登录后空白白屏？ [英] blank white screen after FB login via web app?

问题描述

我已经尝试按照FB移动网络入门指南：
https://developers.facebook.com/docs/guides/mobile/web/
为我的iPhone上全屏打开的网络应用程序。

I have tried following the FB mobile web "getting started guide" at: https://developers.facebook.com/docs/guides/mobile/web/ for a web app that I open full-screen on my iphone.

，但是当我尝试使用打开的fb登录页面登录时，点击登录按钮后，我会看到一个空白的白色屏幕。用户登录了..我知道这是因为如果我关闭并重新打开我的网络应用程序，我检查登录状态，并尝试获取一些用户信息，它的工作正常...

but when I try to login using the fb login page that opens up, I get a blank white screen after I click the "login" button. The user IS logged in though.. I know this because if I close and reopen my web app, I check the login status and try to get some user info, and it works fine...

当我在桌面的Chrome或iPhone的Safari中尝试相同的网络应用程序时，登录过程就可以...只能从全屏网络应用程序中打破。

When I try the same web app in my desktop's chrome or my iphone's safari, the login process is ok... it break only from within the full screen web app.

任何想法？我只是按照FB的示例代码： - （

any ideas?? I'm merely following the sample code from FB :-(

谢谢。

推荐答案

我找到了一个解决方法的问题...似乎有一个无证的'redirect_uri'属性我可以在login（）方法中使用，例如

I have found a workaround to the issue... seems there is an undocumented 'redirect_uri' attribute I can use in the login() method, e.g.

login({scope:'email', redirect_uri:'where_to_go_when_login_ends'})

它记录了fb桌面SDK，所以我给它一个工作，当我说一种，我的意思是在网络移动，似乎可以，但如果你试图运行它在桌面浏览器中，登录弹出窗口将重定向到登录弹出窗口中的给定url - 不在其父窗口中。

It IS documented for fb desktop SDKs, so I gave it a go and it sort of works. When I say "sort of", I mean that on web mobile, it seems ok, but if you try to run it in a desktop browser, the login popup will redirect to the given url within the login popup - not within its parent window.

我希望这样够好，不会导致任何副作用，我真的不能告诉，但这是我在此期间缺乏其他选项：^）

I hope this is good enough and does not cause any side effects, I really can't tell. But this is what I'll use in the meantime for lack of other options :^)
