如何在角度服務中將接口作為參數發送到 HTTP 獲取請求

Question

難以將接口作為 HTTP get 請求的參數傳遞

示例.service.ts

 export interface Product{
    Id:any;
    product : any;
   }

public getProduct(item:Product): Observable<any> {
    const base = this.http.get('/api/getproducts', item);
    const request = base.pipe(
      map((data: TokenResponse) => {
        console.log('display data==>', data);
          return data;
      })
    );
    return request;
  }

樣本.component.ts

 this.ps.getProduct(this.product).subscribe(
      data => {
               console.log("results",data.results)
             });

使用HttpParams傳遞您的參數，如下所示：

const headers = new HttpHeaders().append('header', 'value');
const params = new HttpParams().append('Id', item.ID);
const params = new HttpParams().append('product', item.product);
this.http.get('url', {headers, params});
