IIS 上托管的 Angular 2:HTTP 错误 404 [英] Angular 2 Hosted on IIS: HTTP Error 404

问题描述

我有一个简单的应用程序，其中一个组件需要来自 url 的某些参数.应用程序中只有一个路由:

I have simple app with one component that expects certain parameters from url. there is only one route in the application:

const appRoutes: Routes = 
                       path: 'hero/:userId/:languageId',component: HeroWidgetComponent }];

在 Index.html 中，我在标题 <base href="/">

In the Index.html, I have this in the header <base href="/">

我正在使用 webpack 并且应用程序在开发环境中运行良好，浏览 url 时:http://localhost:4000/hero/1/1.

I am using webpack and the application runs fine on development environment, when browsing the url: http://localhost:4000/hero/1/1.

但是，在构建用于生产的应用程序并获取分发文件时，然后将其托管在 IIS 上.尝试浏览相同的网址时出现以下错误:

However, when building the app for production and getting the distribution files, then hosting that on IIS. I get the following Error when trying to browse the same url:

HTTP Error 404.0 - Not Found
The resource you are looking for has been removed, had its name changed, or is temporarily unavailable.

如果我删除所有路由并在 IIS 上浏览:http:localhost:4200，应用程序工作正常.

The application works fine if I remove all the routing and just browse: http:localhost:4200 on the IIS.

推荐答案

我们必须通过添加重写规则让 IIS 回退到 index.html.

We have to make IIS fall back to index.html by adding a rewrite rule.

第 1 步:安装IIS URL重写模块

第 2 步:向 web.config 添加重写规则

Step 2: Add a rewrite rule to web.config

   <?xml version="1.0" encoding="utf-8"?>
    <configuration>
      <system.webServer>
        <rewrite>
          <rules>
            <rule name="AngularJS Routes" stopProcessing="true">
              <match url=".*" />
              <conditions logicalGrouping="MatchAll">
                <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />   
              </conditions>
              <action type="Rewrite" url="/" />
            </rule>
          </rules>
        </rewrite>
      </system.webServer>
    </configuration>
