dotnet core api version

출처 : https://dotnetcoretutorials.com/2017/01/17/api-versioning-asp-net-core/

Install-Package Microsoft.AspNetCore.Mvc.Versioning

1	Install-Package Microsoft.AspNetCore.Mvc.Versioning

startup.cs

public void ConfigureServices(IServiceCollection services)
{
 // ApiVersioning을 추가
 services.AddApiVersioning(options =>
 {
     // 클라이언트에 Api 버전을 통지
     options.ReportApiVersions = true;
     // 이것이 없으면 클라이언트 측에서 에러가 나온다
     options.AssumeDefaultVersionWhenUnspecified = true;
     // Api의 default 버전을 1.0으로 설정
     options.DefaultApiVersion = new ApiVersion(1, 0);
 });
}

public void ConfigureServices(IServiceCollection services)

{

// ApiVersioning을 추가

services.AddApiVersioning(options =>

{

// 클라이언트에 Api 버전을 통지

options.ReportApiVersions = true;

// 이것이 없으면 클라이언트 측에서 에러가 나온다

options.AssumeDefaultVersionWhenUnspecified = true;

// Api의 default 버전을 1.0으로 설정

options.DefaultApiVersion = new ApiVersion(1, 0);

});

}

출처에 보면 여러가지 방식(Url Query Based Versioning, URL Path Based Versioning, Http Header Based Versiong) 등이 있으나…

역시 익숙한 방식은

[ApiVersion("1.0")]
[Route("api/{version:apiVersion}/home")]
public class HomeV1Controller : Controller
{
	[HttpGet]
	public string Get() => "v1";
}
[ApiVersion("2.0")]
[Route("api/{version:apiVersion}/home")]
public class HomeV2Controller : Controller
{
	[HttpGet]
	public string Get() => "v2";
}

[ApiVersion("1.0")]

[Route("api/{version:apiVersion}/home")]

public class HomeV1Controller : Controller

{

[HttpGet]

public string Get() => "v1";

}

[ApiVersion("2.0")]

[Route("api/{version:apiVersion}/home")]

public class HomeV2Controller : Controller

{

[HttpGet]

public string Get() => "v2";

}

혹은

[ApiVersion("1.0")]
[ApiVersion("2.0")]
[Route("v{version:apiVersion}/[controller]")]
public class HomeController : Controller
{
 [HttpGet]
 public string Get() => "v1";

 // Api 버전을 덮어 쓰기
 [HttpGet, MapToApiVersion("2.0")]
 public string GetV2() => "v2";
}

[ApiVersion("1.0")]

[ApiVersion("2.0")]

[Route("v{version:apiVersion}/[controller]")]

public class HomeController : Controller

{

[HttpGet]

public string Get() => "v1";

// Api 버전을 덮어 쓰기

[HttpGet, MapToApiVersion("2.0")]

public string GetV2() => "v2";

}

/v1/Home, /v2/Home 의 형식으로 call 가능함
