ASP.NET Core - 尝试创建一个按 ID 删除多条记录的端点

Question

我正在尝试创建一个应该删除多个 ID 的端点。它应该匹配deleteRoom(ids: number[])。您可以在下面看到我尝试过的内容，但它与 angular 的请求不匹配。

deleteRoom(ids: number[]) {
  return this.httpClient.delete(`${this.actionUrl}?id=${ids.toString()}`);
}

public class RoomsController : ApiControllerBase
{
    [HttpGet]
    public async Task<ActionResult<IList<RoomDto>>> GetRooms()
    {
        var result = await Mediator.Send(new GetRoomsQuery()).ConfigureAwait(false);

        return Ok(result);
    }

    [HttpGet("available")]
    public async Task<ActionResult<IList<RoomDto>>> GetAvailableRooms(
        [FromQuery] DateTime from,
        [FromQuery] DateTime to,
        [FromQuery] int? departmentId,
        [FromQuery] RoomType? roomType)
    {
        var query = new GetAvailableRoomsQuery
        {
            From = from,
            To = to,
            DepartmentId = departmentId,
            RoomType = roomType
        };

        var result = await Mediator.Send(query).ConfigureAwait(false);

        return Ok(result);
    }


    [HttpPost]
    public async Task<ActionResult<int>> Create(CreateRoomCommand command)
    {
        return await Mediator.Send(command).ConfigureAwait(false);
    }

    [HttpPut("{id:int}")]
    public async Task<ActionResult> Update(int id, UpdateRoomCommand command)
    {
        if (id != command.Id) return BadRequest();

        await Mediator.Send(command).ConfigureAwait(false);

        return NoContent();
    }

    [HttpDelete("{id:int}")]
    public async Task<ActionResult> Delete(int id)
    {
        await Mediator.Send(new DeleteRoomCommand {Id = id}).ConfigureAwait(false);

        return NoContent();
    }

    [HttpDelete("{ids}")]
    public async Task<ActionResult> Delete(int[] ids, DeleteRoomsCommand command)
    {
        await Mediator.Send(command).ConfigureAwait(false);

        return NoContent();
    }
}

Answer 1

在get request中有两种方式使用多个id

1. 路线值

你的网址应该是这样的（你可以用别的东西代替“，”）

http:\\....\deleteRooms\1,2,3,4

动作应该是这样的

[HttpGet("DeleteRooms/{ids}")] //or httpdelete
public ActionResult DeleteRooms(string ids)
{
  string[] roomIds = ids.split(",");
  ...
}

1. 查询字符串

http:\\....\deleteRooms?ids=1&ids=2&ids=3&ids=4

动作可以是

[HttpGet("DeleteRooms")] //or httpdelete
public ActionResult DeleteRooms(int[] ids)
{
   ...
}

Answer 2

如果您注意到，在您的 API 代码中，您需要一个整数，但您传递的是一个逗号分隔的数字（它是一个字符串）

[HttpDelete("{id:int}")]
public async Task<ActionResult> Delete(int id)
{

一种选择是将int 更改为string 并在控制器代码中进行字符串拆分。

public async Task<ActionResult> Delete(string ids)
{
  // split ids into array of int values. "1,2" into [1,2] using string.split
