nestjs中生成uuid

Posted 2021-06-29 久天.

nodejs中有一个uuid的生成库uuid：https://www.npmjs.com/package/uuid,使用起来非常简单。

快速开始

要创建随机UUID，可以使用npm或者yarn安装uuid库

1.使用npm或者yarn安装uuid

npm install uuid --save

或者

yarn add uuid

2. 服务端创建一个UUID

common.service.ts

import { Injectable } from '@nestjs/common';
import { v4 as uuidv4 } from 'uuid';

@Injectable()
export class DashboardService {
  // 获取uuid
  async getUuid(): Promise<any> {
    try {
      const data = uuidv4()
      return data;
    } catch (error) {
      return {
        code: 503,
        msg: `Service error: ${error}`,
      };
    }
  }
}

common.controller.ts

import { Controller, Get, UseInterceptors } from '@nestjs/common';
import { TransformInterceptor } from 'src/common/httpHandle/transform.interceptor';
import { CommonService } from "./common.service";

@Controller('/rest/common')
export class DashboardController {
  constructor(private readonly commonService: CommonService ) {}

  @Get('op/uuid')
  @UseInterceptors(new TransformInterceptor())
  async getUuid() {
    return await this.commonService.getUuid()
  }
}

3. 前端使用

api.ts

Vue中Axios封装API接口的方法

import request from '@/utils/request';
const DASHBOARD_URL = '/rest/common/op'
/**
 * @description: 允许传入prefix，生成UUID 
 * @param {any} data prefix	选填	String	前置字符
 * @return {*}
 */
export const getUuid = () => {    
  return request({
    url: `${DASHBOARD_URL}/uuid`,
    method: 'get'
  })
}

demo.vue

import { getUuid } from '@/api/workbench'
import { IResp } from '@/api/types'
public async getUuid() {
  const { data }: IResp = await getUuid()
}
