加载块模块失败：升级到 Angular 7答案

【问题标题】：Loading chunk module failed: Upgrade to angular 7加载块模块失败：升级到 Angular 7

【问题描述】：

我的应用程序托管在 IIS 上。升级到 Angular 7 后，我收到错误“加载块模块失败”。它似乎不是从 dist/ 文件夹中获取文件，而是试图从根文件夹中获取。 .js 文件正在 dist/ 文件夹中创建。

这是我的 index.html：

<!doctype HTML>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>ABClth</title>
  <base href="/">

  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="icon" type="image/x-icon" href="favicon.ico">
</head>
<body>
  <app-root></app-root>
</body>
</html>

这是我的 angular.json 文件：

  },

}

这是我的 ts.config 文件。

【解决方案1】：

尝试设置公共路径：

publicPath: '/vuebundles/',

/vuebundles/ 将是您的应用程序文件夹名称。当您在 iis 中的站点下托管 Angular 应用程序时，您必须指定公共路径。

另一种方法是您可以使用 iis URL 重写扩展并在 web.config 文件中添加以下规则：

<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="/MyApp/" />
    
      </rule>

    </rules>

  </rewrite>

</system.webServer>

</configuration>
