客户有需求，要短信或者其它场景中的链接静态H5页面，触发打开自家的小程序，官方也提供了 静态网站 H5 跳小程序技术文档（https://developers.weixin.qq.com/miniprogram/dev/wxcloud/guide/staticstorage/jump-miniprogram.html ），不过里面只描述跳转到小程序本身绑定的云开发环境，那么是多个小程序共享的云开发环境如何实现跳转呢，该文档并没有说。
为每个小程序购买一个云开发环境当然是可以，然而，成本似乎似乎太高，不合算，为了给客户节省成本，就给一个小程序买了云开发环境，按照跨账号环境共享设置，实现共享给同主体下的不同小程序（参考：https://developers.weixin.qq.com/miniprogram/dev/wxcloud/guide/resource-sharing/）。
接下来我把最终结果和解决方案，贴出来共享。
场景：首先同公司名下有4个小程序：A、B、C、D，只为A小程序购买了最基础的云开发环境19块，开通静态网站，添加跨账号共享功能，实现访问同一个静态H5页面携带不同参数，打开B、C、D不同小程序的指定页面，无论是微信里还是在手机浏览器均可以跳转。
实现代码：
1、云函数public编写（参考并改进 https://developers.weixin.qq.com/miniprogram/dev/wxcloud/guide/staticstorage/jump-miniprogram.html ）
// 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) {
case 'getUrlScheme': {
return getUrlScheme(event)
}
}
return 'action not found'
}
async function getUrlScheme(event) {
if(event.appid) {
var clb = cloud.openapi({ appid: event.appid });
} else{
var clb = cloud.openapi;
}
return clb.urlscheme.generate({
jumpWxa: {
path: event.path,
query: event.query,
},
// 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),
})
}
2、静态H5页面：jump.html

调用方式：https://xxxx.xxx.xxx/jump.html?id=1&path=my/xwt-apply/xwt-apply (修改成你云环境静态网页的域名)
id=1 表示jump.html页面中小程序B，path 表示小程序B中的具体页面。
你可以尝试修改成自己的，实现传参跳转到不同小程序页面。希望对你有帮助！
