Angular2 提供

Question

我今天将我的项目升级到 Angular RC 到 Final，但我在转换时遇到了问题 =>

provide(Http, {
   useFactory: (xhrBackend: XHRBackend, requestOptions: RequestOptions, accountEventService: AccountEventsService) => {
       return new HmacHttpClient(xhrBackend, requestOptions, accountEventService);
   },
   deps: [XHRBackend, RequestOptions, AccountEventsService],
   multi: false
}

我尝试在最终版本中使用相同的代码，但我没有找到解决方案。

感谢您的帮助

Answer 1

语法已更改为对象字面量，例如：

{provide: Http, 
   useFactory: (xhrBackend: XHRBackend, requestOptions: RequestOptions, accountEventService: AccountEventsService) => {
       return new HmacHttpClient(xhrBackend, requestOptions, accountEventService);
   },
   deps: [XHRBackend, RequestOptions, AccountEventsService],
   multi: false
}
