Angular2提供

Question

我今天我的項目升級到RC角到決賽，我必須轉換問題=>

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

我嘗試使用與最終版本相同的代碼，但我不發現了一些解決方案。

感謝的對你有所幫助

Answer 1

的語法已更改爲對象常量，如：

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