nodejs中有一个uuid的生成库uuid：[https://www.npmjs.com/package/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][Vue_Axios_API]

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()
    }
