通过JavaScript打开Facebook的连接窗口? [英] Opening facebook connect window via javascript?

问题描述

当某人尝试通过Facebook登录到我的网站时，他被重定向到一个页面，在该页面上他可以看到所有请求的权限，然后单击以允许/禁止它们.

When someone tries to login to my site via facebook, he's redirected to a page where he sees all the requested permissions and click to allow / disallow them.

有什么办法可以通过javascript在不让用户离开我的网站的情况下将页面作为分层窗口打开?例如，当Facebook连接窗口悬停在其上方时，我的网站将处于后台.

Is there any way to have this page open up as a layered window through javascript without having the user leave my website? E.g so my website would be in the background while the facebook connect window hovers above it.

有什么想法吗?

推荐答案

答案是否定的.另外，由于Facebook为该页面提供了分帧器，因此您无法在IFrame中加载登录页面.

The answer is no. Also, you can't load the login page within an IFrame since Facebook has a frame breaker for that page.

您正在谈论的页面称为 OAuth对话框.默认情况下，由于"display"参数设置为"page"(其他值包括:popup，iframe，touch和wap)，请求用户登录到您的应用将导致页面重定向.您想要的是在显示设置为"iframe"的情况下调用此对话框.但是，文档状态:如果指定iframe，则必须具有有效的access_token."并且，要获得access_token，用户需要首先登录到您的应用程序.因此，您将无法在嵌入式IFrame中显示登录页面.

The page you're talking about is called the OAuth dialog. By default, requesting users to login to your app will cause a page redirect since the "display" parameter is set to "page" (other values include: popup, iframe, touch, and wap). What you want is to invoke this dialog with display set to "iframe". However, the documentation states: "If you specify iframe, you must have a valid access_token." And, to get an access_token, the user needs to first login to your app. For that reason, you won't be able show the login page within an embedded IFrame.

但是，一旦用户使用基本权限集授权了您的应用，您就可以通过对话框的显示模式将其提示为"iframe"来提示该用户其他权限(因为您具有access_token).

However, once a user authorizes your app with a basic permission set, you may prompt that user for additional permissions with the dialog's display mode to "iframe" (since you have the access_token).
