Nestjs:无法在同一个控制器中实现多个 GET 方法

Nestjs: Cant implement mutiple GET methods in same controller

我这里有一些奇怪的问题。我有 2 种获取方法,一种是通过 companyId 获取员工列表,通过 staffId 获取员工详细信息。第二种方法 getStaffById 不起作用。如果我注释掉第一个 get 方法 getStaffByCompanyId,第二个按预期工作。看起来第一个 get 方法阻塞了第二个方法。我错过了什么吗?

@Controller('staff')
@ApiTags('Staff')
export class StaffController {
  constructor(private staffService: StaffService) {}

  @Get(':companyId')
  @ApiResponse({
    status: HttpStatus.OK,
    description: 'Return staffs by id',
  })
  @ApiResponse({
    status: HttpStatus.UNAUTHORIZED,
    description: 'Unauthorized',
    type: Error,
  })
  @ApiResponse({
    status: HttpStatus.UNPROCESSABLE_ENTITY,
    description: 'Get particular staff details',
    type: Error,
  })
  @ApiResponse({
    status: HttpStatus.INTERNAL_SERVER_ERROR,
    description: 'Internal server error',
    type: Error,
  })
  @ApiResponse({
    status: HttpStatus.BAD_GATEWAY,
    description: 'Internal communication error',
    type: Error,
  })
  @ApiOperation({
    operationId: 'getStaffByCompanyId',
    summary: 'Get staff list that attach to the company',
  })
  async getStaffByCompanyId(@Param('companyId') companyId: string): Promise<IStaff[]> {
    return await this.staffService.getStaffByCompanyId(companyId);
  }

  @Get(':staffId')
  @ApiResponse({
    status: HttpStatus.OK,
    description: 'Return staff by id',
  })
  @ApiResponse({
    status: HttpStatus.UNAUTHORIZED,
    description: 'Unauthorized',
    type: Error,
  })
  @ApiResponse({
    status: HttpStatus.UNPROCESSABLE_ENTITY,
    description: 'Get particular staff details',
    type: Error,
  })
  @ApiResponse({
    status: HttpStatus.INTERNAL_SERVER_ERROR,
    description: 'Internal server error',
    type: Error,
  })
  @ApiResponse({
    status: HttpStatus.BAD_GATEWAY,
    description: 'Internal communication error',
    type: Error,
  })
  @ApiOperation({
    operationId: 'getStaffById',
    summary: 'Get staff profile details',
  })
  async getStaffById(@Param('staffId') staffId: string): Promise<IStaff> {
    return await this.staffService.getStaffById(staffId);
  }
}


Express(Nest 最有可能在后台为您使用的)无法区分

app.get('/:companyId', (req, res, next) => {})

app.get('/:staffId', (req, res, next) => {})

因为它只能看到将有一个请求,其中某种通用参数作为字符串传入,所以虽然您可能知道 companyIdC 开头staffIdS 开头,无法告诉 Express,因此,也无法告诉 Nest 告诉 Express。你能做的最好的事情就是在你的路由中添加一个前缀,比如 /comapny/:companyId/staff/:staffId,以确保它们保持分开。
