Angular2使用外部json配置文件进行异步引导

/** Create dummy XSRF Strategy for Http. */
const XRSF_MOCK = provide(XSRFStrategy,{ provide: XSRFStrategy,useValue:  new FakeXSRFStrategyService() });

/** Create new DI. */
var injector = ReflectiveInjector.resolveAndCreate([ConfigService,HTTP_PROVIDERS,XRSF_MOCK]);

/** Get Http via DI. */
var http = injector.get(Http);

/** Http load config file before bootstrapping app. */
http.get('./config.json').map(res => res.json())
    .subscribe(data => {

        /** Load JSON response into ConfigService. */
        let jsonConfig: ConfigService = new ConfigService();
        jsonConfig.fromJson(data);

        /** Bootstrap AppCOmponent. */
        bootstrap(AppComponent,[...,provide(ConfigService,{ useValue: jsonConfig })
    ])
    .catch(err => console.error(err));
});

这工作得很好,但很难改变与RC6一起工作.

我正在尝试以下方法,但很难修改带有加载数据的预定义AppModule：

const platform = platformBrowserDynamic();

if (XMLHttpRequest) { // Mozilla,Safari,...
  request = new XMLHttpRequest();
} else if (ActiveXObject) { // IE
  try {
    request = new ActiveXObject('Msxml2.XMLHTTP');
  } catch (e) {
    try {
      request = new ActiveXObject('Microsoft.XMLHTTP');
    } catch (e) {
      console.log(e);
    }
  }
}
request.onreadystatechange = function() {
  if (this.readyState === 4 && this.status === 200) {
    var json = JSON.parse(this.responseText);
    let jsonConfig: ConfigService = new ConfigService();
    jsonConfig.fromJson(json);
    /**** How do I pass jsConfig object into my AppModule here?? ****/
    platform.bootstrapModule(AppModule);
  }
};

// Open,send.
request.open('GET','./config.json',true);
request.send(null);
