javascript - 如何为每个 API 创建通用的 Nest JS API 响应格式？

问题描述

我是 Nestjs 的新手，一直坚持为所有 API 制作一个通用的响应体。目前，我正在使用地图从集合中获取响应，但不知道如何以下面提到的方式格式化响应。

我目前正在收到如下响应正文-

Response body        
        
[         
  {            
    "userId": "602a0f175bbd45688cd001f4",        
    "firstName": "Gagan",  
    "lastName": "Pandya",  
    "email": "gagankumar.pandya@galaxyweblinks.in",  
    "status": "active"  
  },  
  {
    "userId": "603f3b547508bbd77a3d6fb5",    
    "firstName": "Kunal",    
    "lastName": "Ghosh",    
    "email": "kunal.ghosh@galaxyweblinks.in",    
    "status": "active"    
  }    
]

需要将其设置为-

{
    "statusCode": 200,   
    "message": "User Listing",   
    "data":[    
  {   
    "userId": "602a0f175bbd45688cd001f4",    
    "firstName": "Gagan",   
    "lastName": "Pandya",   
    "email": "gagankumar.pandya@galaxyweblinks.in",   
    "status": "active"    
  },    
  {    
    "userId": "603f3b547508bbd77a3d6fb5",    
    "firstName": "Kunal",    
    "lastName": "Ghosh",     
    "email": "kunal.ghosh@galaxyweblinks.in",      
    "status": "active"    
  }     
]    
}

下面是我的控制器代码 -

  @Get('/users-listing')    
  // @UseGuards(AuthGuard('jwt'))    
 // @Roles('Super Admin')    
  @ApiOperation({ title: 'Lists of users' })    
  @ApiOkResponse({})    
  @HttpCode(HttpStatus.OK)    
  async getAllUsers() {    
    return this.usersService.findAllUsers();    
  }

并请找到 service.ts 文件代码 -

   async findAllUsers(): Promise<User[]> {     
    const users = await this.userModel.find().exec();   
    const usersArr = [];    
    await Promise.all(    
      users.map(async users => {    
        usersArr.push({ userId: users._id, firstName: users.firstName, lastName: users.lastName, email: users.email, status: users.status });    
      }),    
    );    
    return usersArr;    
  }    

    Thanks in advance!
