前置条件：
非个人已认证小程序
1.在微信开发者工具中点击 云开发->更多->静态网站，开通静态网站
2.创建云函数 微信开发者工具中点击 云开发->云函数->新建
函数名称可随意取 例如：public
3.在原有小程序工程或新建小程序工程，project.config.json文件中添加"cloudfunctionRoot": "static/cloudbase/",
在uni-app中manifest.json->源码视图 "mp-weixin"下添加"cloudfunctionRoot":"static/cloudbase/"
4.在static文件夹下创建cloudbase/public文件夹，这个public为创建云函数时取得名称

5.新建index.js文件
// 云函数入口文件
const cloud = require('wx-server-sdk')
cloud.init()
// 云函数入口函数
exports.main = async (event, context) => {
const wxContext = cloud.getWXContext()
switch (event.action) {
case 'getUrlScheme': {
return getUrlScheme(event.ocd)
}
}
return 'action not found'
}
async function getUrlScheme(ocd) {
return cloud.openapi.urlscheme.generate({
jumpWxa: {
path: '/page/xxx/xxx', // 不能带参数 由query传入
query: 'id=111',//参数可由此传入
},
// 如果想不过期则置为 false，并可以存到数据库
isExpire: false,
// 一分钟有效期
expireTime: parseInt(Date.now() / 1000 + 60),
})
}
6.编译后在public文件夹上点击右键 上传并部署
7.新建index.html文件并上传到静态网站，访问即可
