javascript - Angular Http参数未发送

我正在尝试使用以下方法发出获取请求：

    let ht = new HttpHeaders({
    'Content-Type': 'application/json',
    'Authorization': 'my-auth-token',
    'params': '{where:{id: 1}}'
});
return this.http.get(environment.apiUrl + route, {headers: ht});

请求通过但未发送参数，谁能告诉我我在做什么错？

最佳答案

您必须使用来自http的HttpParams将额外的参数发送到api调用。

import {HttpHeaders, HttpParams } from '@angular/common/http';

let ht = new HttpHeaders({
    'Content-Type': 'application/json',
    'Authorization': 'my-auth-token',
});

//Create new HttpParams
let p= new HttpParams().
         set("param1",p1).
         set("param2", p1);

return this.http.get(environment.apiUrl + route, {headers: ht, params: p});
