創建ValueV1和ValueV2兩個測試控制器
<code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
namespace WebApiVersion.Controllers
{
[ApiVersion("1.0",Deprecated =true)]
[Route("api/values")]
[ApiController]
public class ValuesV1Controller : ControllerBase
{
[HttpGet]
public IEnumerable<string> Get()
{
return new string[] { "Value1 from Version 1", "value2 from Version 1" };
}
}
}/<string>/<code>

接口默認返回設置的為2.0，現在請求1.0接口，使用Header方式
<code> [ApiVersionNeutral]
[Route("api/[controller]")]
[ApiController]
public class HealthCheckController : ControllerBase
{
public string Get()
{
return "Good";
}
}/<code>
