为什么我不能在 NestJS 中映射更多 api？

Question

添加 http://localhost:8080/api/v1/admin (GET) 以使用 NestJS 开发 api，我们添加了 Get 注释并继续开发 api，但未映射 api，如果调用 api，将发生 404notfound 错误。 什么样的问题？

// admin.controller.ts

import { Body, Controller, Get, HttpCode, Post, UseGuards } from '@nestjs/common';
import {
    ApiTags,
    ApiOperation,
    ApiResponse,
  } from '@nestjs/swagger';

import { AdminService } from './admin.service';
import { CreateAdminDto } from './dto/create.admin.dto';
import { LoginAdminDto } from './dto/login.admin.dto';
import { Admin } from 'src/entities/admin.entity';

@Controller('admin')
@ApiTags('관리자 API')
export class AdminController {
constructor(
    private readonly adminService: AdminService
) {}

@Get('/')
@UseGuards(HttpAuthGuard)
@ApiOperation({ summary: '내 정보 보기', description: '내정보 보기' })
@ApiResponse({ status: 200, description: '내 정보 조회 성공' })
public async findOne(@ReqAdmin() admin: Admin): Promise<BaseResponse> {
    const data = await this.adminService.findOneById(admin.id);
    return BaseResponse.object('내정보 조회 성공', { 
        data,
    })
}

@Post('/')
@ApiOperation({ summary: '관리자 생성 API', description: '관리자를 생성한다.' })
@ApiResponse({ status: 201, description: '관리자 생성성공' })
public async create(@Body() createAdminDto: CreateAdminDto) {
    await this.adminService.create(createAdminDto);
    return BaseResponse.object('관리자 생성성공')
}

@Post('/login')
@HttpCode(200)
@ApiOperation({ summary: '관리자 로그인 API', description: '관리자 로그인' })
@ApiResponse({ status: 200, description: '관리자 로그인성공', type: String })
public async login(@Body() loginAdminDto: LoginAdminDto) {
    const token = await this.adminService.login(loginAdminDto);
    return BaseResponse.object('관리자 로그인성공', { 
        'x-access-token': token 
    })
  }
}

// admin.module.ts

import { Module } from '@nestjs/common';
import { TypeOrmModule } from '@nestjs/typeorm';
import { Admin } from 'src/entities/admin.entity';
import { TokenModule } from 'src/token/token.module';

       Admin
     ])
  ],
  providers: [AdminService, TokenService],
  exports: [AdminService],
  controllers: [AdminController]
})
export class AdminModule {}

看起来你已经为你的 api /api/v1添加了前缀

您可以尝试调用http://localhost:8080/api/v1/admin而不是http://localhost:8080/admin
