使用HttpCode装饰器

通常 post 请求会返回 201 状态码

@HttpCode(HttpStatus.OK)

// auth.service.ts
import { Body, Controller, HttpCode, HttpStatus, Post } from '@nestjs/common';
import { AuthService } from './auth.service';
import { AuthDto } from './dto';

@Controller('auth')
export class AuthController {
  constructor(private authService: AuthService) {}

  @HttpCode(HttpStatus.OK)
  @Post('signin')
  signin(@Body() dto: AuthDto) {
    return this.authService.signin(dto);
  }
}
