微信小程序实现短信登录的方法_F11 - 专业站长和开发者的学习网站

1.界面效果预览

2.uView安装

uView官网：
以npm安装为例,执行：npm install uview-ui即可

3.uView配置

3.1 main.js中引入

import uView from "uview-ui";
Vue.use(uView);

3.2 uni.scss中引入

@import 'uview-ui/theme.scss';

3.3 App.vue中引入

<style lang="scss">
    /* 注意要写在第一行，同时给style标签加入lang="scss"属性 */
    @import "uview-ui/index.scss";
</style>

3.4 pages.json中配置

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

注意如果easycom中还有别的配置有可能会导致uView样式无法加载

4.短信登录界面

<template>
  <view class="wrap">
    <view class="login">
      <view class="login-logo">
        <image src="../../../../static/img/logo.png"
               mode=""></image>
      </view>
      <view class="form-view"></view>
    </view>

    <u-form :model="model"
            ref="uForm">
      <u-form-item :rightIconStyle="{ color: '#888', fontSize: '32rpx' }"
                   :label-position="labelPosition"
                   label="手机号码"
                   prop="phone"
                   label-width="150">
        <u-input :border="border"
                 placeholder="请输入手机号"
                 v-model="model.phone"
                 type="number"></u-input>
      </u-form-item>
      <u-form-item :label-position="labelPosition"
                   label="验证码"
                   prop="code"
                   label-width="150">
        <u-input :border="border"
                 placeholder="请输入验证码"
                 v-model="model.code"
                 type="text"></u-input>
        <u-button slot="right"
                  type="success"
                  size="mini"
                  @click="getCheckNum">{{ codeTips }}</u-button>
      </u-form-item>

      <view class="bot-view">

        <button class="btn btn-submit"
                @click="doLogin">登录</button>
      </view>
    </u-form>
    <u-verification-code seconds="60"
                         ref="uCode"
                         @change="codeChange"></u-verification-code>
  </view>
</template>

5.点击获取验证码接口

import utilTools from '../../../../utils/UtilTools.js';
import { isMobile } from '../../../../utils/validate.js';
    getCheckNum() {
            let obj = utilTools.getParams();
            obj.method = 'xxx';
            obj.message = JSON.stringify({ mobile_phone: this.model.phone });
            this.$Api.getDataFromWeb(obj).then(data => {
                    if (!!data && data['success'] == 'true') {
                        this.$refs.uCode.start();
                    } else {
                        this.$Api.messHint(`${data.detail}`);
                    }
                })
                .catch(err => {
                     this.$Api.messHint(`${err.errMsg}`);
                });
        }

UtilTools中封装的方法

import Request from './request.js';
const request = new Request().http;

hostAddress:'xxxx',

getDataFromWeb:function(data){
        return request(`${this.hostAddress}`,data,'POST')
    }

点击获取验证码按钮，调用后端接口，后端接口封装了调用阿里云短信的方法，向当前传入的手机号中发送固定的模板信息，验证码可由后端随机生成写入到模板中。
