Nestjs에서 Request Header validate 처리 방법
Validate Headers 를 참고해서 처리 했습니다.
validateCustomDecorators 옵션을 true롤 꼭 설정 해야 합니다.
// main.ts
async function bootstrap() {
 // ... 
 app.useGlobalPipes(
 new ValidationPipe({
 validateCustomDecorators: true // <-- Add this to allow the validation pipe to work with our custom decorator
 })
 );
 // ...
}
bootstrap();
// request-header.decorator.ts
export const RequestHeaders = createParamDecorator(
 async (property: string | number | symbol, ctx: ExecutionContext) => {
 const headers = ctx.switchToHttp().getRequest().headers;
 if (
 typeof property === 'string' ||
 typeof property === 'number' ||
 typeof property === 'symbol'
 ) {
 return headers[property];
 }
 return headers;
 },
);
// refresh-header.dto.ts
export class RefreshHeaderDTO {
 @IsString()
 @IsDefined()
 @Expose({ name: 'authorization' })
 authorization: string;
}
// app.controller.ts
@Controller()
export class AppController {
 constructor(private readonly appService: AppService) {}
 ApiOperation({ summary: '사용자 토큰 만료시 refresh 토큰으로 호출' })
 @Post('/refresh')
 refresh(@RequestHeaders() headers: RefreshHeaderDTO) {
 return this.userService.tokenRefresh(
 headers.authorization.split('Bearer ')[1],
 );
 }
}
