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 ) ;
} ) ;
}
출처에 보면 여러가지 방식(Url Query Based Versioning, URL Path Based Versioning, Http Header Based Versioning) 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" ;
}
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" ;
}
/v1/Home, /v2/Home 의 형식으로 call 가능함
