相对路径在 angular 中不起作用

Question

当我在“http://localhost/overview”时，模块是沿着这个路径加载的：

http://localhost/app/modules/overview/overview.module.js

但是当我转到 http://localhost/overview/users 页面然后按 F5（刷新页面）时，出现错误：

Error: Unexpected token <
  Evaluating http://localhost/overview/app/modules/overview/overview.module

错误发生是因为URL不正确，他应该是http://localhost/app/modules/overview/overview.module.

如何让它正常工作？

这是项目结构：

这是 systemjs tsconfig:

{
  "compileOnSave": true,
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [ "es2015", "dom" ],
    "noImplicitAny": false,
    "suppressImplicitAnyIndexErrors": true
  }
}

这是 systemjs 配置：

(function (global) {
    System.config({
        baseURL: "/",
        paths: {
            'npm:': '/node_modules/'
        },

        },
        packages: {
            app: {
                main: './bootstrap.js',
                defaultExtension: 'js'
            },
            rxjs: {
                defaultExtension: 'js'
            }
        }
    });
})(this);

更新

应用-routing.module:

import {RouterModule, Routes} from "@angular/router";
import {NgModule} from "@angular/core";
import {LoginFormComponent} from "./modules/auth/login-form/login-form.component";

const routes :Routes = [
    {path: "auth", component: LoginFormComponent},
    {path: "overview", loadChildren: "./app/modules/overview/overview.module#OverviewModule"}
];

@NgModule({
    imports: [RouterModule.forRoot(routes)],
    exports: [RouterModule]
})
export class AppRoutingModule{

}

概述。routing.module:

import {RouterModule, Routes} from "@angular/router";
import {NgModule} from "@angular/core";
import {OverviewComponent} from "./overview/overview.component";

const routes :Routes = [
    {path: "", component: OverviewComponent, children:[
        {path: "users", loadChildren: "/app/modules/users/users.module#UsersModule"}
    ]}
];

@NgModule({
    imports: [RouterModule.forChild(routes)],
    exports: [RouterModule]
})
export class OverviewRoutingModule{

}

用户-routing.module:

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import {UsersListComponent} from "./users-list/users-list.component";
import {UserElementComponent} from "./user-element/user-element.component";

const routes: Routes = [
    {path: "", component: UsersListComponent},
    {path: ":id", component: UserElementComponent},
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class UsersRoutingModule { }

在我使用的组件 module.id 中，查找示例 overview.component.ts:

@Component({
    selector: "overview",
    moduleId: module.id,
    templateUrl: "./overview.component.html",
    providers:[
        OverviewService
    ]
})
export class OverviewComponent implements OnInit {

    constructor(private overviewService :OverviewService) {}

    public ngOnInit() {
        let data = this.overviewService.getOverview();
        Log.info(data);
    }

}

Answer 1

您在用户模块的路径中有前导 /。

改成这样：

 {path: "users", loadChildren: "app/modules/users/users.module#UsersModule"}

Answer 2

在您的模块路由中，它不会从您的 AppRouting 延迟加载中获取 "overview"。你会认为它应该，但事实并非如此。

将您的路线更改为：

const routes :Routes = [
        {path: "overview", component: OverviewComponent, pathMatch: 'full' }, 
        {path: "overview/users", loadChildren: "app/modules/users/users.module#UsersModule"}
    ]}
];

和

const routes: Routes = [
    {path: "overview/users", component: UsersListComponent},
    {path: "overview/users/:id", component: UserElementComponent},
];

做了一些改动。将所有延迟加载放入 AppRoutingModule 中，并添加了一个包装器 class，因此 Overview 部分可以有自己的 router-outlet。您可以看到在它们之间单击如何与概览和概览 2
