angular7post提交的例子

  postDemo() {
    const params = new HttpParams();
    params.set('aaa', '111111');
    params.set('bbb', '22222');

    this._httpClient.post('http://127.0.0.1:12345/snap/timer', params).
    subscribe(
      (res) => {
        console.log(res);
      },
      (err) => {
        console.log(err);
      }
    );
  }

 

服务器注意跨域配置，类似echo的

c.Response().Header().Set("Access-Control-Allow-Origin", "*")
