uni-app开发小程序一键登录的实现方式？

<script setup lang="ts">
// import { postLoginWxMinAPI, postLoginWxMinSimpleAPI } from '@/services/login'
// import { useMemberStore } from '@/stores'
// import type { LoginResult } from '@/types/member'
import { onLoad } from '@dcloudio/uni-app'

// #ifdef MP-WEIXIN
// 获取 code 登录凭证
let code = ''
onLoad(async () => {
  const res = await wx.login()
  code = res.code
})

// 获取用户手机号码
const onGetphonenumber: UniHelper.ButtonOnGetphonenumber = async (ev) => {
  const { encryptedData, iv } = ev.detail
  const res = await postLoginWxMinAPI({ code, encryptedData, iv })
  loginSuccess(res.result)
}
// #endif

// 模拟手机号码快捷登录（开发练习）
const onGetphonenumberSimple = async () => {
  const res = await postLoginWxMinSimpleAPI('13123456789')
  loginSuccess(res.result)
}

const loginSuccess = (profile: LoginResult) => {
  // 保存会员信息
  const memberStore = useMemberStore()
  memberStore.setProfile(profile)
  // 成功提示
  uni.showToast({ icon: 'success', title: '登录成功' })
  setTimeout(() => {
    // 页面跳转
    // uni.switchTab({ url: '/pages/my/my' })
    uni.navigateBack()
  }, 500)
}
