1. 在react的useEffect里使用官方提供的云登录示例见code
2. 在instance.init时出错了：errCode: -601022  | errMsg: 找不到对应的FunctionName

见代码：

useEffect(async () => {

// try {

require('../utils/cloud');

// 公众号基本信息：请修改下列字段使用本示例

const WX_RESOURCE_APPID = 'wxeb151f49f6b2beea'; /* 资源方 AppID */

const WX_RESOURCE_ENVID =

'youhuima-7g2kzr7h9e6d34f7'; /* 资源方云开发环境 ID */

const WX_OFFICIAL_ACCOUNT_APPID = 'wx3e4700970958fcec'; /* 公众号 AppID */

const WX_AUTH_TYPE =

'snsapi_base'; /* 选择需要的授权方式，snsapi_base 或 snsapi_userinfo */

const WX_REDIRECT_URI = 'http://m.youhuima.life/'; /* 回调 URL */

// 示例配置

const isPersistLoginInfo = false; // 是否需要保留登录态信息到 window 中，只有 snsapi_userinfo 方式需要

if (window.wx) {

window.cloud = wx.cloud;

}

var urlSearch = new URLSearchParams(location.search);

var accessToken = urlSearch.get('access_token');

var refreshToken = urlSearch.get('refresh_token');

const checkLoginOptions = {

provider: 'OfficialAccount',

appid: WX_OFFICIAL_ACCOUNT_APPID,

};

if (urlSearch.get('oauthredirect') === '1') {

checkLoginOptions.accessToken = accessToken;

checkLoginOptions.refreshToken = refreshToken;

}

console.log(`checkLogin options: `, checkLoginOptions);

const result = await cloud.checkLogin(checkLoginOptions);

console.log(`checkLogin result: `, result);

if (isPersistLoginInfo) window.checkLoginRes = result;

if (result.errCode === 0 && result.loggedIn) {

console.log(`checkLogin success`);

const instance = (window.instance = new cloud.Cloud({

appid: WX_OFFICIAL_ACCOUNT_APPID,

resourceAppid: WX_RESOURCE_APPID,

resourceEnv: WX_RESOURCE_ENVID,

}));

console.log('--------initial-----', instance);

const initResult = await instance.init();

console.log('--------initial done ----');

// console.log(`instance inited`, initResult);

console.log(`can use cloud instance to access resource now !`);

// const els = [...document.getElementsByClassName('display-none')];

// els.forEach((el) => el.classList.remove('display-none'));

} else {

console.log(

`checkLogin with sdk errCode ${result.errCode} errMsg ${result.errMsg}, will start oauth in 10s`

);

});
