HATEOAS的Angular2支持

import { Injectable } from '@angular/core';
import { HttpClient, HttpEvent, HttpInterceptor, HttpHandler, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';

@Injectable()
export class HATEOASInterceptor implements HttpInterceptor {
  constructor(private http: HttpClient) {}

  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    return next.handle(req).pipe(
      map(event => {
        if (event instanceof HttpResponse) {
          // 解析API响应，提取超链接信息
          const links = event.headers.get('Link');
          // 处理超链接信息，转换为可用的资源和操作
          // ...
        }
        return event;
      })
    );
  }
}

// 在Angular模块中注册拦截器
@NgModule({
  providers: [
    { provide: HTTP_INTERCEPTORS, useClass: HATEOASInterceptor, multi: true }
  ]
})
export class AppModule { }
