Asp.net核心2.2多个获取请求

问题描述

我使用本教程从核心2.2开始 []，提交序列号并更改颜色但风格相同。



一切顺利，直到我想要过滤选择，所以我需要第二次（和第三次）GET。使用Postman我得到一个重复的GET错误

https：// localhost：44334 / api / userdetails？FleetID = 1



Startup.cs中没有路由



我尝试过：



控制器以
开头

 [路线（api / [控制器]）] 
 [ApiController] 
 public class UserDetailsController：ControllerBase 
 {
 DAL.UserDetails dsUserDetails = new UserDetails（）; 
 
 [HttpGet] 
 public ActionResult< IEnumerable< UserDetailsDB>> GetUsers（）
 {
 IEnumerable< UserDetailsDB> lResult = dsUserDetails.UserDetailsList（）; 
返回lResult.ToList（）; 
} 

带有额外过滤器的第二个GET - 这个的装饰或GET的调用语法

 [HttpGet] 
 public ActionResult< IEnumerable< UserDetailsDB>> GetUserForFleet（[FromQuery] int FleetID）
 {
 IEnumerable< UserDetailsDB> lResult = dsUserDetails.UserDetailsForFleet（FleetID）; 
返回lResult.ToList（）; 
} 

解决方案

I used this tutorial to start with core 2.2 Tutorial: Create a web API with ASP.NET Core MVC | Microsoft Docs[^], filed off the serial numbers and changed the colour but the same style.

All went well until I wanted to get a filtered selection so I need a second (and third) GET. Using Postman I get a duplicate GET error with
https://localhost:44334/api/userdetails?FleetID=1

There is no routing in the Startup.cs

What I have tried:

Controller starts with

[Route("api/[controller]")]
[ApiController]
public class UserDetailsController : ControllerBase
    {
		DAL.UserDetails dsUserDetails = new UserDetails();

		[HttpGet]
		public ActionResult<IEnumerable<UserDetailsDB>> GetUsers()
		{
			IEnumerable<UserDetailsDB> lResult = dsUserDetails.UserDetailsList();
			return lResult.ToList();
		}

Second GET with additional filter - what is the decoration for this or the calling syntax for the GET

[HttpGet]
public ActionResult<IEnumerable<UserDetailsDB>> GetUserForFleet([FromQuery] int FleetID)
{
  IEnumerable<UserDetailsDB> lResult = dsUserDetails.UserDetailsForFleet(FleetID);
  return lResult.ToList();
}
