WeChat applet implements SMS login in action

WeChat applet implements SMS login in action

The project requires the addition of SMS login and face recognition login functions. Let's implement the SMS login function below

1. Interface effect preview

2.uView installation

uView official website: https://www.uviewui.com
Take npm installation as an example, execute: npm install uview-ui

3.uView configuration

3.1 Introduction in main.js

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

3.2 Introduction to uni.scss

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

3.3 Introduction in App.vue

<style lang="scss">
	/* Note that it should be written in the first line, and the lang="scss" attribute should be added to the style tag*/
	@import "uview-ui/index.scss";
</style>

3.4 Configuration in pages.json

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

Note that if there are other configurations in easycom, it may cause the uView style to fail to load.

4. SMS login interface

<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="Mobile number"
                   prop="phone"
                   label-width="150">
        <u-input :border="border"
                 placeholder="Please enter your phone number"
                 v-model="model.phone"
                 type="number"></u-input>
      </u-form-item>
      <u-form-item :label-position="labelPosition"
                   label="Verification code"
                   prop="code"
                   label-width="150">
        <u-input :border="border"
                 placeholder="Please enter the verification code"
                 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">Login</button>
      </view>
    </u-form>
    <u-verification-code seconds="60"
                         ref="uCode"
                         @change="codeChange"></u-verification-code>
  </view>
</template>

5. Click to get the verification code interface

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}`);
				});
		}

Methods encapsulated in UtilTools

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

hostAddress:'xxxx',

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

Click the Get Verification Code button to call the backend interface. The backend interface encapsulates the method of calling Alibaba Cloud SMS and sends a fixed template information to the currently passed mobile phone number. The verification code can be randomly generated by the backend and written into the template.
