Question

我刚刚启动了一个ASP.NET MVC Web应用程序，它使用Angular作为其UI组件。将必要的配置文件发送到我的项目中（例如package.json和systemjs.config.js）。创建测试页Index.cshtml以测试app.component.ts模板。在我的localhost下运行时，应用程序正在运行。我可以看到从模板中呈现自定义标记<user-app>的页面。

但问题是，当我将Web应用程序部署到IIS（开发服务器）时，我遇到了以下HTTP404: NOT FOUND - The server has not found anything matching the requested URI (Uniform Resource Identifier)。

这是应用package.json文件

应用systemjs.config.js文件

    /**

(function (global) {
    System.config({
        paths: {

        // map tells the System loader where to look for things
        map: {

            rxjs: {
                defaultExtension: 'js'
            }
        }
    });
})(this);

app.component.ts文件

    import { Component } from '@angular/core';

@Component({
    selector: 'user-app',
    template: `
        <div>
            <nav class='navbar navbar-inverse'>
                <div class='container-fluid'>
                    <ul class='nav navbar-nav'>

            </div>
        </div>
    `
})
export class AppComponent {}

main.ts文件

    import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';

platformBrowserDynamic().bootstrapModule(AppModule);

app.module.ts文件

    import { NgModule } from '@angular/core';
import { APP_BASE_HREF } from '@angular/common';
import { BrowserModule } from '@angular/platform-browser';
import { ReactiveFormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';
import { AppComponent } from './app.component';
import { routing } from './app.routing';
import { HomeComponent } from './Components/home.component';

@NgModule({
    imports: [BrowserModule, ReactiveFormsModule, HttpModule, routing],
    declarations: [AppComponent, HomeComponent],
    providers: [{ provide: APP_BASE_HREF, useValue: '/' }],
    bootstrap: [AppComponent]
})
export class AppModule {}

和app页面_Layout.cshtml文件

    <!DOCTYPE html>
<html>
<head>
    <base href="/" />
    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>@ViewBag.Title - Control Systems Management</title>
    @Styles.Render("~/Content/css")
    @Scripts.Render("~/bundles/modernizr")
    <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/systemjs/dist/system.src.js"></script>
    <script src="~/systemjs.config.js"></script>
    <script>
        //SystemJS.config({
        //    baseURL: '.'
        //});

        System.import('app').catch(function (err) {
            console.error(err);
        });
    </script>
</head>
<body>
    <div class="container body-content">
        @RenderBody()
    </div>

    @Scripts.Render("~/bundles/jquery")
    @Scripts.Render("~/bundles/bootstrap")
    @RenderSection("scripts", required: false)
</body>
</html>

同样在IIS中，我已经配置了一个应用程序，并在ControlSystem下将其命名为Default Web Site。查看http error，服务器找不到main.js，因为它被认为是相对路径（例如http://myDomain/controlsystem/app/main.js）。我尝试了几种方法来配置systemjs.config.js，但它没有成功。

这是我的visual studio项目中的.ts个文件的文件夹结构

我在网上做了一些关于如何解决这个问题的研究，但我找不到类似的问题。如果有，请指导我这样的参考。

我非常擅长Angular并在线浏览以了解所有这些相关的配置设置。

非常感谢任何帮助。

Answer 1

为了可能遇到此问题的其他开发人员的利益。幸运的是，我找到了解决方案。

这是一个非常简单的解决方案。在_Layout.cshtml内<head>部分，将<base href="~/" />作为第一个元素。

根据此文档https://angular.io/guide/router，<base href="/">告诉Angular路由器URL的静态部分是什么。然后，路由器仅修改URL的剩余部分。在我的情况下，我不得不把~“代替”以使其相对。

希望这会有所帮助。

如何配置systemjs.config.js以在IIS中使用相对路径？
