Question

我正在使用ASP.NET Core和AngularJS 2. http查询参数存在问题。无论我尝试什么，参数'quarter'都不会传递给控制器。任何人都知道我在这里失踪了什么？

getBookingsBySaleUnit() {
    let params: URLSearchParams = new URLSearchParams();
    params.set('quarter', '1');
    let requestOptions = new RequestOptions();
    requestOptions.search = params; 

    this.http.get('/api/method', requestOptions).subscribe(result => {
            this.sales = result.json();
        }
      );
  }

Answer 1

这对我有用：

    let params: URLSearchParams = new URLSearchParams();
    params.set('quarter', 1);
    this.http.get('Result/Delete', { search: params })
       .subscribe([...])

Answer 2

您错过了传递参数。请尝试以下代码，其中包含网址中的参数。

getBookingsBySaleUnit() {
    let params: URLSearchParams = new URLSearchParams();
    params.append('quarter', '1');
    let requestOptions = new RequestOptions();
    requestOptions.headers.set('Content-Type', 'application/x-www-form-urlencoded');
    this.http.get('/api/method?'+params.toString(), requestOptions).subscribe(result => {
        this.sales = result.json();
    });
}

如何在AngularJS 2中传递查询参数？
