发布订阅EventPattern

@MessagePattern: 基于rpc比较喜欢用，一个菠萝一个坑

// 网关
@Get('/hello')
async getHello(): Promise<any> {
  const pattern = 'sum';
  const payload = [1, 2];
  // this.client.emit(pattern,payload)没有返回值
  const it = await this.client.send<number[]>(pattern, payload);
  return `收到返回值: ${it}`;
}

// 服务
@EventPattern('sum')
sum(data: number[]): number {
  return (data || []).reduce((a, b) => a + b);
}
