system.import的Angular 2错误路径(' app')

我有一个带有angular2元素的项目asp.net-mvc。用于启动iis应用程序,该应用程序在Home文件夹中启动index.cshtml(从主控制器启动)。所以,我修改了angular,如下所示,索引文件:

<!DOCTYPE html>
<html>
<head>
    <title>Angular QuickStart</title>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link href="~/styles.css" rel="stylesheet" />
    <!-- Polyfill(s) for older browsers -->
    <script src="~/node_modules/core-js/client/shim.min.js"></script>
    <script src="~/node_modules/zone.js/dist/zone.js"></script>
    <script src="~/node_modules/reflect-metadata/Reflect.js"></script>
    <script src="~/node_modules/systemjs/dist/system.src.js"></script>
    <script src="~/systemjs.config.js"></script>
    <script>
      System.import('app').catch(function(err){ console.error(err); });
    </script>
</head>
<body>
    <my-app>Loading AppComponent content here ...</my-app>
</body>
</html>

现在,当我启动应用程序System.import('app')时,找不到应用程序文件夹,因为请执行此操作:

  

zone.js:1382 GET http://localhost/app/main.js 404(未找到)

但是,如果我手动调用家庭控制器,请正确显示路径:

  

http://localhost/my_virtual_path/app/main.js

为什么会这样? 我可以更改system.import以查看相对于项目级别的路径吗?

为了完整性,这是system.config.js

/**
 * System configuration for Angular samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    paths: {
      // paths serve as alias
        'npm:': 'node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
        app: 'app',

      // angular bundles
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      '@angular/common': 'npm:@angular/common/bundles/common.umd.js',

      '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',

      // other libraries
      'rxjs':                      'npm:rxjs',
      'angular-in-memory-web-api': 'npm:angular-in-memory-web-api/bundles/in-memory-web-api.umd.js',

      // librerie di terze parti
      'angular2-datatable': 'npm:angular2-datatable',
      'lodash': 'npm:lodash/lodash.js',
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        main: './main.js',
        defaultExtension: 'js'
      },
      rxjs: {
        defaultExtension: 'js'
      },


      'angular2-datatable': {
          main: 'index.js',
          defaultExtension: 'js'
      },

    }
  });
})(this);

首先,我强烈建议您不要使用asp.net mvc或类似的应用程序。不需要它。您可以将它用作休息服务(asp.net web api)。无论如何,我认为这个问题来自应用程序路径(IIS应用程序) 所以你需要将这个标签添加到html文件头:

<head>
<base href="/my_virtual_path/">
