Outlook Javascript API-window.open在Outlook 2016桌面/Windows中不起作用 [英] Outlook Javascript API - window.open not working from Outlook 2016 Desktop/Windows

问题描述

我有一个用新的JavaScript API编写的Office加载项，其中有一个JS函数，该函数经过一些逻辑后便会使用window.open(url, '_blank')

I have an Office Add-In written in the new JavaScript API, inside of it, I have a JS function which after some logic opens a web app in a new window using window.open(url, '_blank')

当在localhost托管加载项中的Outlook Web的加载项窗格中以及在heroku上部署后，都可以使用它.

It works when called from the add-in pane in Outlook Web in both, localhost hosted add-in, as well as after deployment on heroku.

但是，当从命令(功能区上的加载项按钮)调用该加载项时，该加载项仅在主机托管在localhost上时有效，当我将其部署在heroku上后，在功能区中显示命令，执行JS逻辑，但是window.open不执行任何操作.

However when called from a command (add-in button on ribbon) it works only when the add-in is hosted on localhost, after I deploy it on heroku, the add-in works, shows commands in the ribbon, performs the JS logic, but window.open does nothing.

看起来，打开新窗口的唯一方法是使用Office.context.ui.displayDialogAsync，但即使这样，它也只能在页面与加载项源于同一来源时起作用.

Looks like the only way to open a new window is by using Office.context.ui.displayDialogAsync but even then it works only if the page is on the same origin as the add-in code.

我认为存在一些安全限制，但是为什么将其托管在localhost上时又可以工作呢?有什么方法可以使用新的Javascript API在Outlook中的命令中打开浏览器窗口吗?

I would think that there are some security restrictions, but why then it worked when hosted on localhost? Is there any way, to open a browser window from a command in Outlook using the new Javascript API?

推荐答案

我的经验是，window.open在不同平台上并非始终可靠，这迫使您使用Office.context.ui.displayDialogAsync.如前所述，如果您尝试打开不在您的域中的页面，就会大惊小怪.我发现有几种方法可以解决此问题，具体取决于您的使用场景:

My experience with this has been that window.open is not consistently reliable across the different platforms, which sort of forces you to use Office.context.ui.displayDialogAsync. As you mentioned, it fusses at you if you try to open a page that's not on your domain. I've found there's a couple of ways around this that might be viable depending on your usage scenario:

1. 您可以更新清单的<AppDomains>部分，以包括要打开窗口的站点.此部分是一种白名单.
2. 您可以指向您域中的一个页面，该页面的主要目的是将您重定向到其他地方.我没有遇到重定向窗口的限制，只是打开了它.我将这种方法与qstring参数一起使用，以根据需要控制重定向.

1. You can update the <AppDomains> section of your manifest to include the site you want to open up the window to. This section acts as a sort of white list.
2. You can point to a page within your domain that's soul purpose is to redirect you somewhere else. I haven't run into restrictions on redirecting the window, just opening it. I use this method along with qstring parameters to control the redirect as needed.
