说明

验证码服务可自行去申请，不过好像是要企业才能申请，这里
结合uview组件库+mockjs在本地实现发送并获取验证码

配置

验证码组件u-verification-code官网不再维护，但不影响使用可在uniapp直接配置。

在项目pages.json文件中配置好路径

"easycom": {
		"^u-(.*)": "@/uview-ui/components/u-$1/u-$1.vue"
	},

mockjs使用

根目录创建mock文件夹，分别创建mock/index.js,mock/code.json

index.js

import Mock from 'mockjs'
import code from './code.json'
Mock.mock('/mock/code',{code:200,data:code,msg:"获取验证码成功"})

code.json

[
  "1234","4553","2346","9765","4567","4589","0087","4538","8796"
]

封装axios，创建请求api

根目录下创建utils

utils/mockRequest.js

import axios from '@/js_sdk/gangdiedao-uni-axios'
//根据自身情况引入axios

// 创建自定义接口服务实例
const http = axios.create({
	baseURL: '/mock',//根据个人后端情况，修改此处baseURL
	timeout: 6000, // 不可超过 manifest.json 中配置 networkTimeout的超时时间
	withCredentials: true,
	headers: {
		'Content-Type': 'application/json',
		//'X-Requested-With': 'XMLHttpRequest',
	},
})

// 拦截器 在请求之前拦截   添加token
http.interceptors.request.use(config => {
	//请求前有关处理逻辑
	return config
})
// 响应后的拦截
http.interceptors.response.use(response => {
    //响应拦截处理逻辑
	return response;
}, error => {
	
	return Promise.reject(error.message)
})

export default http

根目录创建api文件夹

api/index.js

import mockRequest from '@/utils/mockRequest.js'

//验证码
export const getCode = () => mockRequest.get('/code')

main.js注册全局api

import * as API from '@/api/index.js'
Vue.prototype.$API = API

前端调用

template

<u-input style="width: 300rpx" v-model="code" placeholder="请输入验证码" />
<view class="bd-primary xs orange br60 flex row-center" @click="sendSmsFun" hover-class="none">
  <!-- 获取验证码 -->
  <u-verification-code unique-key="register" ref="uCode" @change="codeChange">
  </u-verification-code>
  <view class="xs">{{codeTips}}</view>
</view>

script

async sendSmsFun() {
        // if (!this.$refs.uCode.canGetCode) return
        if (!this.registerForm.mobilePhoneNumber) {
          this.$common.errorToShow('请填写手机号信息～');
          return;
        }
        console.log("111");
        const {
          data: res
        } = await this.$API.getCode()
        console.log(res);
        if (res.code == 200) {
          this.$common.successToShow(res.msg)
          this.$refs.uCode.start();
          //获取随机验证码
          var random = Math.floor(Math.random() * 9)
          this.code = res.data[random]
        }
      },

codeChange(tip) {
        this.codeTips = tip
      },

效果
