1. Background introduction

Mini Program URL Scheme and URL Link are addresses generated by the WeChat Mini Program background and are suitable for opening any page of the Mini Program from text messages, emails, web pages outside WeChat, etc. Therefore, the applicability is extremely strong. It can complement the technology of scanning QR code on WeChat and carrying parameters to jump to the specified page of the mini program.

If opened outside WeChat, users can click on the browser page to enter the mini program. After each independent URL Link is accessed by a user, only this user can access and open the corresponding applet again, and other users cannot open the applet through the same URL Link again. The maximum validity period can be set to 30 days.

2. Code implementation

// 这里是前端代码实现了整个逻辑，生产项目应该后端接口封装好，前端调用，传递参数
const getUrlLink = () => {
    uni.request(
      {
        url:`https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=appid&secret=secret`,
        method: 'GET',
        success: ((res:any) =>{
          console.log(res)
          uni.request(
            {
              url:'https://api.weixin.qq.com/wxa/generate_urllink?access_token=' + res.data.access_token,
              method: 'POST',
              data: {
                access_token: wx.getStorageSync('token'),
                path: 'pages/XXX/index',
                query: ''
              },
              success: ((res:any) => {
                console.log(res2)
                // 访问微信中间页面，点击进入小程序，携带参数访问微信小程序指定页面
                location.href = res2.data.url_link
              })
            }
          )
