Angular2：将服务器端配置注入服务

我在 ASP.NET Core 中使用 Angular 2.0.0 和 TypeScript。我的目标是根据服务器端变量在我的应用程序中创建 AppConfig 服务。在其他几个答案的帮助下，我能够创建以下代码：

索引.cshtml

<app>
    <i class="fa fa-spin fa-5x fa-spinner"></i>
</app>

<script>
    System.import('/app/main').then((m) => {
        var config = {
            apiUrl: @options.ApiServerUrl
        };

        m.RunApplication(config);
    }, console.error.bind(console));
</script>

应用程序配置.ts

import { Injectable } from "@angular/core";

@Injectable()
export class AppConfig {
    apiUrl: string;
}

main.ts

import { platformBrowserDynamic } from "@angular/platform-browser-dynamic";

import { AppModule } from "./app.module";
import { AppConfig } from "./app.config";

export function RunApplication(config: Object) {

    var appConfig = new AppConfig();
    appConfig.apiUrl = config["apiUrl"];

    console.log('Created config: ', appConfig);

    platformBrowserDynamic()
        .bootstrapModule(AppModule, [{ providers: [{ provide: AppConfig, useValue: appConfig }] }])
        .catch(err => console.error(err));
}

应用程序模块.ts

import { NgModule } from "@angular/core";
import { BrowserModule } from "@angular/platform-browser";
import { HttpModule } from "@angular/http";
import { AppRouting, AppRoutingProviders } from "./app.routes";
import { AppConfig } from "./app.config";
import { AppComponent } from "./app.component";
import { DashboardComponent } from "./dashboard/dashboard.component";
import { DashboardService } from "./dashboard/dashboard.service";

@NgModule({
    declarations: [
        AppComponent,
        DashboardComponent
    ],
    imports: [
        BrowserModule,
        HttpModule,
        AppRouting
    ],
    providers: [
        AppRoutingProviders,
        AppConfig,
        DashboardService
    ],
    bootstrap: [AppComponent],
})
export class AppModule { }

仪表板.service.ts

import { Http } from "@angular/http";
import { Injectable } from "@angular/core";
import { Observable } from "rxjs/Rx";
import "rxjs/add/operator/map";
import { AppConfig } from "../app.config";

@Injectable()
export class DashboardService {

    constructor(private appConfig: AppConfig, private http: Http) {
        console.log('Injected config: ', appConfig);
        console.log('Injected apiUrl: ', appConfig.apiUrl);
    }
}

Chrome 控制台的输出

正如您所看到的，由于某种原因创建并注入AppConfig不一样，并且apiUrl值没有出现在DashboardService。我怀疑错误就在这里：

bootstrapModule(AppModule, [{ providers: [{ provide: AppConfig, useValue: appConfig }] }])

但我对 Angular2 还很陌生，不知道如何修复它。你能指点我问题出在哪里吗？

Your AppConfig提供者在@NgModule()提供者传递给的影子bootstrapModule()

With 如何将从后端渲染的参数传递给 angular2 bootstrap 方法你应该得到你想要的。
