将多个参数传递给 DELETE 请求 c# web API

Question

我的问题是如何将多个参数传递给 DELETE 请求。

我的控制器class如下，

namespace MYAPI1.Controllers
{
    public class TaskController : ApiController
    {
        // DELETE: api/Task/5
        [Route("api/Task/id1/id2/{id3}")]
        public void Delete(int id,int id2, string id3)
        {
            TaskPersistent tp = new TaskPersistent();
            tp.deleteTask(id,id2,id3);
        }
    }
}

TaskPersistent.class如下，

public class TaskPersistent
{
    public void deleteTask(int id, int id2, string id3)
    {

        try
        {
            string sqlString = "DELETE from devproj WHERE (DeveloperID, ProjectID, WorkDate) =  VALUES ('" + id + "', '" + id2 + "', '" + id3 + "');";
            MySql.Data.MySqlClient.MySqlCommand cmd = new MySql.Data.MySqlClient.MySqlCommand(sqlString, conn);
            cmd.ExecuteNonQuery();
            long x = cmd.LastInsertedId;

        }
        catch (Exception x)
        {
            Console.WriteLine(x);
        }

    }

}

我尝试像这样使用邮递员来使用它，http://localhost:10927/api/Task?id1=1&id2=5&id3="2018-03-14" 但是这不起作用，请帮我解决这个问题。

Answer 1

尝试以下方法

    [Route("api/Task/{id:int}/{id2:int}/{id3}")]
    public void Delete(int id,int id2, string id3)
    {
        TaskPersistent tp = new TaskPersistent();
        tp.deleteTask(id,id2,id3);
    }

通过以下方式调用：http://localhost:10927/api/Task/1/2/"2018-03-14"

--- 或 ---

    [Route("api/Task")]
    public void Delete(int id,int id2, string id3)
    {
        TaskPersistent tp = new TaskPersistent();
        tp.deleteTask(id,id2,id3);
    }

通过以下方式调用：http://localhost:10927/api/Task?id=1&id2=2&id3="2018-03-14"

尝试传递视图模型：

public class YourViewModel {
     public int Id1 { get; set;} 
     public int Id2 { get; set;} 
     public string Id3 { get; set;} 

   }

然后

[HttpPost]
[Route("api/Task")]
 public void Delete([FromBody] YourViewModel model)
 {
     TaskPersistent tp = new TaskPersistent();
     tp.deleteTask(model.Id1, model.Id2, model.Id3);
 }

这样您就不必在查询字符串中指定参数。但是你必须确保请求头有：

'Content-Type: application/json'

更新： 如果您需要尝试一下，这就是您在使用 JQuery:

时需要从客户端调用它的方式

var myModel= { Id1:1, Id2:11 Id3:"test" }
$.ajax({
    type: 'POST',
    url: 'http://localhost:10927/api/Task',
    data: JSON.stringify(myModel),
    contentType: 'application/json;',
    dataType: 'json',
    success: function(data){  }
});

[HttpDelete]
public async Task<IActionResult> Delete(List<string> ids)
{
  await _mapService.RemoveAsync(ids);
  var ret = CreatedAtAction(nameof(Delete), new { ids = ids }, ids);

  return ret;
}

Curl

curl -X 'DELETE' \
  'https://localhost:44307/api/Map' \
  -H 'accept: */*' \
  -H 'Content-Type: application/json' \
  -d '[
  "623b35de9f6cedc3a22f7b37",
"623b35de9f6cedc3a22f7b38"
