<template><view class="mainContent"><image class="closeImg" @click="onCloseClick"src="quicklogin_close.png"></image><view class="centerLayout"><image class="logoImg" src="quicklogin_logo.png"mode="scaleToFill"/><view class="phoneTxt">188****8888</view><view class="serviceTxt">天翼账号提供认证服务</view><button class="btnLogin" open-type="getPhoneNumber" @getphonenumber="getPhoneNumber">本机号码一键登录</button><view class="other" @click="onOtherLoginClick">其他登录方式</view></view><view class="agreementLayout"><u-checkbox-group v-model="checked" placement="column" @change="onCheckboxChange"><u-checkbox size="30rpx" activeColor="#ff1b1b" :name="true"></u-checkbox></u-checkbox-group><view class="agreementTxt">我已阅读并同意外卖狮<text style="color: #F72124;font-weight: bold"@click="NavTo('/packageB/pages/Agreement/userAgreement')">用户协议</text>和<text style="color: #F72124;font-weight: bold"@click="NavTo('/packageB/pages/Agreement/concealAgreement')">隐私政策</text>并使用本机号码登录</view></view></view>
</template><script setup>
import {Back, NavTo, SwcTo} from "@/utlis/uni_api";
import {getCurrentInstance, ref} from "vue";
import {wxGetPhoneNumber, wxPhoneNumberLogin} from "@/utlis/innerface/userLogin";const checked = ref("")
let code = ""
let {proxy} = getCurrentInstance();//微信获取手机号信息
const getPhoneNumber = (datas) => {console.log(datas)//微信小程序返回的相关数据uniLogin(datas)
}const uniLogin = (datas) => {uni.login({provider: 'weixin',success: res => {console.log(res)code = res.codelet params = {code: code,iv: datas.detail.iv,encryptedData: datas.detail.encryptedData}//请求后台,获取手机号和codewxGetPhoneNumber(params, proxy).then(res => {userLogin(res.code,res.phoneNumber)}).catch((err) => {console.log("wxGetPhoneNumber err = ", err)})}});
}//关闭
const onCloseClick = () => {Back()
}//一键号码登录
const userLogin = (sCode,phoneNumber) => {let params = {code: sCode,phoneNumber: phoneNumber}//后台登录wxPhoneNumberLogin(params, proxy).then(res => {uni.setStorageSync('token', res.data.accessToken)uni.setStorageSync('activityShowType', true)setTimeout(() => {SwcTo('/pages/Home/home')}, 200)}).catch((err) => {console.log("wxPhoneNumberLogin err = ", err)})
}//其他号码登录
const onOtherLoginClick = () => {NavTo('/packageB/pages/Login/Login')
}//复选框选中监听
const onCheckboxChange = (e) => {console.log(e)
