angular部署到iis出现404解决方案

angular应用部署在iis上时，刷新出现404

解决方案：

安装 iis URL Rewrite 模块，配置urlrewrite如下：

在 src 目录下增加web.config，内容如下：

<configuration>
<system.webServer>
  <rewrite>
    <rules>
      <rule name="Angular 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>

配置 web.config 自动打包

修改 angular-cli.json文件(angular2-5)

  "apps": [
        {
       "root": “src”,
       "ourDir": “dist”,
       "assets": [
          “assets”,
          “favicon.ico”,
          “web.config”
          ],

修改 angular.json 文件(angular6)

        “build”: {
       "options”: {
         . . . 
         "assets": [
            “src/assets”,
            “src/favicon.ico”,
            “src/web.config”
             ],
