带有外部json配置文件的Angular2异步引导

我有同样的问题。好像您遇到了我的要点
:-)

至于RC6更新，您应该签出HttpModule源。它显示了最初已被删除的所有提供程序

HTTP_PROVIDERS

function getHttp(): Http {  let providers = [    {      provide: Http, useFactory: (backend: XHRBackend, options: RequestOptions) => {        return new Http(backend, options);      },      deps: [XHRBackend, RequestOptions]    },    BrowserXhr,    { provide: RequestOptions, useClass: baseRequestOptions },    { provide: ResponseOptions, useClass: baseResponseOptions },    XHRBackend,    { provide: XSRFStrategy, usevalue: new NoopcookieXSRFStrategy() },  ];  return ReflectiveInjector.resolveAndCreate(providers).get(Http);}

至于

platform.bootstrapModule(AppModule);

它不是最漂亮的（实际上还不错），但是从[ 这篇文章中]
我发现了一个我什至不知道的可能。看起来您可以在函数 内部 声明模块。

function getAppModule(conf) {  @NgModule({    declarations: [ AppComponent ],    imports:      [ BrowserModule ],    bootstrap:    [ AppComponent ],    providers:    [      { provide: Configuration, usevalue: conf }    ]  })  class AppModule {  }  return AppModule;}

下面是我现在用来测试的内容

import { ReflectiveInjector, Injectable, OpaqueToken, Injector } from '@angular/core';import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';import { BrowserModule } from '@angular/platform-browser';import { NgModule } from '@angular/core';import { Observable } from 'rxjs/Observable';import 'rxjs/add/operator/toPromise';import {  Http, cookieXSRFStrategy, XSRFStrategy, RequestOptions, baseRequestOptions,  ResponseOptions, baseResponseOptions, XHRBackend, BrowserXhr, Response} from '@angular/http';import { AppComponent } from './app.component';import { Configuration } from './configuration';class NoopcookieXSRFStrategy extends cookieXSRFStrategy {  configureRequest(request) {    // noop  }}function getHttp(): Http {  let providers = [    {      provide: Http, useFactory: (backend: XHRBackend, options: RequestOptions) => {        return new Http(backend, options);      },      deps: [XHRBackend, RequestOptions]    },    BrowserXhr,    { provide: RequestOptions, useClass: baseRequestOptions },    { provide: ResponseOptions, useClass: baseResponseOptions },    XHRBackend,    { provide: XSRFStrategy, usevalue: new NoopcookieXSRFStrategy() },  ];  return ReflectiveInjector.resolveAndCreate(providers).get(Http);}function getAppModule(conf) {  @NgModule({    declarations: [ AppComponent ],    imports:      [ BrowserModule ],    bootstrap:    [ AppComponent ],    providers:    [      { provide: Configuration, usevalue: conf }    ]  })  class AppModule {  }  return AppModule;}getHttp().get('/app/config.json').toPromise()  .then((res: Response) => {    let conf = res.json();    platformBrowserDynamic().bootstrapModule(getAppModule(conf));  })  .catch(error => { console.error(error) });
