我想创建一个使用Http模块发送请求的简单辅助函数。
using UnityEngine;
using System.Collections;
//Add this class to your world game object and store your globals here
public class GlobalContext : MonoBehaviour{
}
public class BaseClass : MonoBehaviour {
private GlobalContext world;
void Start() {
//find the cabinet object in your scene
world= transform.root.GetComponent<GlobalContext>();
}
}
但我不知道如何将Http作为依赖注入。

我会创建一个扩展Http
的HTTP拦截器:
import { Http, Request, RequestOptionsArgs, Response, XHRBackend, RequestOptions, ConnectionBackend, Headers } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/catch';
import 'rxjs/add/operator/do';
import 'rxjs/add/operator/finally';
import 'rxjs/add/observable/timer';
export class HttpService extends Http {
constructor(backend: ConnectionBackend, defaultOptions: RequestOptions) {
super(backend, defaultOptions);
}
request(url: string | Request, options?: RequestOptionsArgs): Observable<Response> {
return this.intercept(super.request(url, options));
}
get(url: string, options?: RequestOptionsArgs): Observable<Response> {
return this.intercept(super.get(url, options));
}
post(url: string, body: any, options?: RequestOptionsArgs): Observable<Response> {
return this.intercept(super.post(url, body, options));
}
put(url: string, body: any, options?: RequestOptionsArgs): Observable<Response> {
return this.intercept(super.put(url, body, options));
}
delete(url: string, options?: RequestOptionsArgs): Observable<Response> {
return this.intercept(super.delete(url, options));
}
intercept(observable: Observable<Response>): Observable<Response> {
return observable
.finally(() => {
serverLog(...) <-- log here
});
}
}
将其导入您的模块,如下所示:
@NgModule({
imports: [
BrowserModule,
HttpModule
],
declarations: [AppComponent, LoadingComponent],
providers: [
{
provide: Http,
useFactory: (backend: XHRBackend, options: RequestOptions) => {
return new HttpService(backend, options);
},
deps: [XHRBackend, RequestOptions]
}
],
bootstrap: [AppComponent],
})
export class AppModule { }
