taro3.x：获取用户信息登录

获取sessionKey及解密数据：

import api from '@services/api'
import app from '@services/request'
import storage from '@utils/storage'

export const fetchSessionKey = (code: string) => {
    return new Promise((resolve) => {
        app.request({
            url: app.apiUrl(api.getSessionKeyByCode),
            data: {
                code
            }
        }).then((result: any) => {
            storage.setItem('session_key', result.session_key, 'login')
            resolve(result)
        })
    })
}

interface IDecryptParam {
    sessionKey: string
    encryptedData: string
    iv: string
}

export const fetchDecryptData = (decryptParam: IDecryptParam) => {
    return new Promise((resolve) => {
        app.request({
            method: 'POST',
            url: app.apiUrl(api.decryptData),
            data: decryptParam
        }, { loading: false }).then((result: any) => {
            resolve(result)
        })
    })

}

登录界面：

import React, { useState } from 'react'
import Taro from '@tarojs/taro'
import { View, Text, Button } from '@tarojs/components'

import storage from '@utils/storage'
import { fetchSessionKey, fetchDecryptData } from '@services/login'
import NavBar from '@components/navbar/index'
import './index.scss'

const Login = () => {
    const navData = {
        title: '',
        back: true,
        color: '#000000',
        backgroundColor: '#ffffff'
    }
    const [loginCode, setLoginCode] = useState<string>('')

    Taro.setNavigationBarColor({
        frontColor: navData.color,
        backgroundColor: navData.backgroundColor
    })

    const handleLogin = () => {
        Taro.login({
            success: function (res) {
                if (res.code) {
                    setLoginCode(res.code)
                }
            }
        })
    }

    const getUserInfo = (e) => {
        const errMsg = e.detail.errMsg
        if (errMsg === 'getUserInfo:ok') {
            fetchSessionKey(loginCode).then((result: any) => {
                fetchDecryptData({
                    sessionKey: result.session_key,
                    encryptedData: e.detail.encryptedData,
                    iv: e.detail.iv
                }).then((result: any) => {
                    const user = {
                        nickName: result.nickName,
                        avatarUrl: result.avatarUrl,
                    }
                    storage.setItem('user', user, 'login')
                    Taro.navigateBack({
                        delta: 1
                    })
                })
            })
        }
    }

    const handleLoginByPhone = () => {
        Taro.navigateTo({
            url: '/login/phone/index'
        })
    }

    return (
        <View className="login">
            <NavBar {...navData} />
            <View className="login-header">
                <Text className="title">房产在线</Text>
                <Text className="small">Fczx.com</Text>
            </View>
            <View className="login-content">
                <View className="login-memo">
                    <View className="cut-line"></View>
                    <Text className="desc">推荐使用登录方式</Text>
                </View>
                <Button
                    className="btn btn-primary"
                    openType="getUserInfo"
                    onGetUserInfo={getUserInfo}
                    onClick={handleLogin}
                >
                    <Text>微信登录</Text>
                </Button>
                <View className="btn btn-plain" onClick={handleLoginByPhone}>
                    <Text>手机快捷登录</Text>
                </View>
            </View>
        </View>
    )
}

export default Login

 

检查sessionKey是否有效 ：

Taro.checkSession({
  success: function () {
    //session_key 未过期，并且在本生命周期一直有效
  },
  fail: function () {
    // session_key 已经失效，需要重新执行登录流程
    Taro.login() //重新登录
  }
})

拨打电话功能：

const handlePhoneCall = () => {
        Taro.makePhoneCall({
            phoneNumber: '1340000' //仅为示例，并非真实的电话号码
          })
    }
