背景
去年年末,离过年的工夫还剩几天,产品部的忽然跑过来问能不能年前做完而后上线一个小程序,利用过年的流量,引流一波。
工夫紧,工作急。并且公司还在开源节流,精简服务器。这个我的项目也就过年这段时间跑跑的,过后就是废除状态。综合种种,于是提出试试小程序的云开发。
小程序云开发劣势
无需搭建服务器,疾速构建小程序,免登录、免鉴权调用微信凋谢服务,按量计费, 还有内容治理(CMS), 小我的项目用云开发在适宜不过了。
这个我的项目除了失常的展现外,还用到以下性能
- 动态网站 H5 跳小程序任意页面
- 客服音讯主动回复
- 订阅音讯推送
以上联合小程序云开发不必后盾参加进来,前端也能很容易的实现起来。
先看看大家比较关心的费用问题
右边是费用,左边是拜访人数,
能够看到每天大略 800-1000 人数的拜访,费用也就几分钱,这还是在开明了内容治理(CMS)状况下的数据。所以对于费用这一块齐全能够打消这个顾虑
动态网站 H5 跳小程序任意页面
老规矩先看文档 https://developers.weixin.qq.com/miniprogram/dev/wxcloud/guide/staticstorage/jump-miniprogram.html
能力
能够在微信外部浏览器的 H5 跳转小程序,也能够在微信内部浏览器或其余局部 App(如企业微信、QQ 等)跳转微信小程序。
依据文档我这里改成了能够跳首页以及任意详情页面

云函数
// 云函数入口文件
const cloud = require('wx-server-sdk')
cloud.init({env: 'id'})
// 云函数入口函数
exports.main = async (event, context) => {const wxContext = cloud.getWXContext()
switch (event.action) {
case 'getUrlScheme': {return getUrlScheme(event)
}
}
return 'action not found'
}
async function getUrlScheme(event) {
let path = '/pages/index/index'
let query = ''
if (event.id) {
path = '/pages/detail/index'
query = 'id=' + event.id
}
return cloud.openapi.urlscheme.generate({
jumpWxa: {
path: path, // <!-- replace -->
query: query,
},
// 如果想不过期则置为 false,并能够存到数据库
isExpire: false,
// 一分钟有效期
expireTime: parseInt(Date.now() / 1000 + 60),
})
}
把云函数部署下来,动态 H5 页面上传到云开发的动态网站里
在 网站配置
里找到域名,就能够 H5 跳小程序了。
