WinRT&打包应用程序后，UWP WebView本地主机URL不触发 [英] WinRT & UWP WebView localhost url doesn't fire when app is packaged

问题描述

男孩，我真的很挣扎！

因此，我有一个WinRT Metro应用程序，该应用程序将HTML网页嵌入到该应用程序的Web视图中.在HTML页面中，有一个div，带有指向本地主机URL的href.我正在使用此localhost调用与正在侦听localhost端口上的该URL的.NET桌面应用程序进行通信.

So I have a WinRT Metro application that has an HTML webpage embedded into a webview within the application. In the HTML page there is a div with an href to a localhost url. I'm using this localhost call to communicate with a .NET desktop application that is listening for this url on a localhost port.

当我在Visual Studio(2015年，更新1或2)中构建应用程序(作为调试或发行版)时，该应用程序将按预期工作.我可以单击div，网址被触发，并且通信成功.

When I build the application (as debug or release) in Visual Studio (2015, update 1 or 2), the application works as expected. I can click on the div, the url is fired, and the communication is successful.

但是，当我打包应用程序并将其侧面加载到我的机器上时，该功能无法正常工作.我可以单击div ...，但永远不会触发该网址.

However, when I package the application and sideload it on to my machine, the functionality does not work as expected. I can click on the div...but the url is never fired.

HTML网址示例([...] =已删除代码):

<a href="http://localhost:8123/?Api [...] >Click here</a>

导航到HTML示例的代码背后:

Codebehind Navigating to HTML Example:

this.webView.Navigate(new Uri("ms-appdata:///local/index.html"));

XAML Webview实例化:

XAML Webview Instantiation:

<WebView x:Name="webView" Grid.Row="1" ScriptNotify="webView_ScriptNotify" Grid.Column="1" Visibility="Collapsed"/>

这是我尝试过的事情:

1. 我创建了一个WinRT应用，该应用仅仅包含Web视图和嵌入式HTML页面.功能在构建时有效，但在打包时无效.
2. 我创建了一个仅的UWP应用，该应用包含Web视图和嵌入式HTML页面.功能在构建时有效，但在打包时无效.
3. 我尝试按照

1. I created a WinRT app that only contained the webview and the embedded HTML page. Functionality works when built, but not when packaged.
2. I created a UWP app that only contained the webview and the embedded HTML page. Functionality works when built, but not when packaged.
3. I tried packaging the app outside of Visual Studio using the command line as described here. The functionality does not work.
4. I tried using different versions of Visual Studio 2015. Same results.
5. I tried building/packaging on different machines. Same results.
6. I tried to navigate to google instead of the localhost. Works.
7. I tried to navigate to another html file instead of the localhost. Works.
8. Naturally, I tried the obvious things too like cleaning, changing package name, changing settings in the Visual Studio App Packager, reboots, removing references, etc.

有人曾经经历过吗?打包过程似乎存在某种错误.欢迎任何建议/提示/答案！谢谢！

Has anyone experienced this before? It seems to be some sort of bug with the packaging process. Any suggestions/tips/answers are welcome! Thanks!

以防万一您想知道，此应用程序仅在我工作的公司内部供企业使用，并且不会上载到Windows应用商店.

And just in case you're wondering, this application is intended for enterprise use only within the company I work for and will not be uploaded to the Windows Store.

推荐答案

通常，您无法在UWP应用商店应用中打开回送连接.句号如果您是侧面加载或在企业环境中，则有一种解决方法:

Normally, you can't open a loopback connection in a UWP store app. Full stop. If you're side loading, or in an enterprise environment, there is a workaround:
