我正在处理 asp.net core(2.1) angular 项目,在这里我将参数从 angular 服务传递到 web API,但我没有在 API 中获取这些值。

下面是我的代码,当我为 Web API 使用单独的项目时,它运行良好。现在,由于我在 asp.net 核心项目本身中创建了一个控制器,因此我无法在 API 参数列表中获取发布的值。

我是否需要添加/更改一些设置以获取从角度服务到 API 调用的值?

角服务:

getSortedPagedResults(filters): Observable<any> {
        debugger;
        return this._http.post(this.myAppUrl + 'api/Employee/EmployeesServerSide', filters);  
      }

接口:

[HttpPost]
    [Route("api/Employee/EmployeesServerSide")]
    public IEnumerable<Users> EmployeesServerSide(Filters filters)
    {
        return objemployee.GetUsersServerSide(filters);
    }

在您的 API 端使用FromBody

public IEnumerable<Users> EmployeesServerSide([FromBody] Filters filters)

}
