无法连接到 Windows 商店应用程序中的本地主机 [英] Cannot connect to localhost in windows store application

问题描述

当我在互联网上阅读时，微软阻止了在本地主机 (127.0.0.1) 上为任何端口侦听和接收流量的选项.我希望开发目的是在本地测试我的 2 个服务器/客户端应用程序.我按照这里的说明进行操作:http://msdn.microsoft.com/en-us/library/windows/apps/hh780593.aspx

As i read all over the internet microsoft block the option to listen and recieve traffic on localhost (127.0.0.1) for any port. I want for developing purposus to test my 2 server/client apps locally. I followed the instruction here: http://msdn.microsoft.com/en-us/library/windows/apps/hh780593.aspx

但它不起作用.当我使用调试选项时，我得到:

but it doesnt work. when I use the debug option I am getting:

InternetClient                Not Used and Insecure
InternetClientServer          Not Used and Insecure
PrivateNetworkClientServer    Not Used and Insecure

详细的流量报告

InternetClient                Not Used and Insecure

<小时>

InternetClientServer          Not Used and Insecure

<小时>

PrivateNetworkClientServer    Not Used and Insecure

<小时>

知道为什么它不起作用吗?

any idea why it doesnt work?

推荐答案

我的方案:为内部使用开发了一个 Windows Store 应用程序，在开发机器上运行良好，但是当迁移到另一台机器时，任何 HttpClient 调用都失败了.我在这里遇到了两个问题:

My scenario: Developed an Windows Store App for internal use, ran fine on development machine, however when migrating to another machine any of the HttpClient calls failed. There are two issues I faced here:

1. 与本地机器上的 IIS 通信时 HttpClient 失败

1. HttpClient failure when communicating to IIS on the local machine

HttpClient 失败，当与本地子网上远程机器上的 IIS 通信时

HttpClient failure When communicating to IIS on a remote machine on the local subnet

问题 2 很容易解决，在 Visual Studio 中将应用设置为允许在功能(Package.appxmanifest > Capabilities)下的私有网络(客户端和服务器)"，重新部署，一切正常不错.

Problem 2 was an easy fix, in Visual Studio set the app to allow "Private Networks (Client & Server)" under the capabilities (Package.appxmanifest > Capabilities), redeploy and all is good.

问题 1 很难解决.默认情况下，Visual Studio 在 NetIsolation 中添加一个允许和拒绝本地环回/本地主机访问的异常.您需要在此列表中添加您的应用作为例外，但是 OP 中提供的链接中的信息不起作用，我根本无法使命令起作用，所以我是这样做的:

Problem 1 was difficult to resolve. By default Visual Studio adds an exception in the NetIsolation which permits and denies local loopback/localhost access. You need to add your app as an exception in this list, however the information in the link provided in the OP doesn't work, I couldn't get the command to work at all, so here's how I did it:

(注意确保应用安装在你运行它的机器上)

1. 转到您的注册表，然后按 CTRL+F 找到您的应用(例如，如果它名为 TESTApp1，则在搜索框中输入该应用).
2. 您应该找到一个注册表项，它看起来像一个 guid 后跟一个名称，例如:ac2efce7-a15b-40d0-92db-3abde43a6778_1.0.1.15_neutral__025mzc78q1aqe

获得该名称后，在命令提示符(以管理员身份，以防万一)中运行:CheckNetIsolation.exe LoopbackExempt -s

Once you have that name, in a command prompt (as administrator, just in case) run : CheckNetIsolation.exe LoopbackExempt -s

在输出中，找到您的 GUID.您将在其下方看到 SID，记下此 SID.3) 运行以下命令，在问题机器上输入您的 SID:CheckNetIsolation.exe LoopbackExempt -a -p=SIDHERE

In the output, find your GUID. You will see the SID under it, make a note of this SID. 3) Run the following command, entering in your SID on the problem machine: CheckNetIsolation.exe LoopbackExempt -a -p=SIDHERE

注意:替代步骤 2:您还可以在以下注册表项下找到您的 SID(假设您已安装该应用):

Note: Alternative step 2: You can also find your SID under the following registry key (assuming you have installed the app):

HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Mappings

再次按 CTRL+F 并在那里找到您的应用.

Again, CTRL+F and find your app under there.
