最最重要的步骤就是配置静态网站！！！
微信参考文档（下载这里的html按标注替换自己的小程序appid）：
https://developers.weixin.qq.com/miniprogram/dev/wxcloud/guide/staticstorage/jump-miniprogram.html
在设置静态网站这步走了很多弯路，是以记录一下，使用mac开发，在App Store下载的‘微信开发者工具’中没有找到静态网站配置项，到官网重新下载一个：https://developers.weixin.qq.com/miniprogram/dev/devtools/download.html
打开微信开发者工具，刚下载的版本：1.05.2103190，点击云开发，这里没开通的按步骤开通一下

开通好静态网站后，修改html内容上传到文件管理中, 点击文件右侧的详情按钮，即可看到下载地址，复制到微信里访问就可以看到跳转按钮。
以下代码中有以下内容必须替换
小程序 AppID：填入你的小程序 AppID
云开发环境 ID：填入你的开通了静态网站托管的云开发环境 ID
小程序原始账号 ID：填入要跳转的小程序原始账号 ID（gh_ 开头）
小程序页面路径：填入要跳转到的小程序的页面路径
小程序名称：填入要跳转到的小程序名称
