  1. 打开第三方小程序

    1. navToCiss(){
    2.  console.log("hi");
    4.  let url = ""
    5.  my.navigateToMiniProgram({
    6.    appId: '2021001166643246',
    7.    path: "pages/sign/sign?q=" + encodeURIComponent(url),
    8.    extraData: {
    10.    },
    11.    success(){},
    12.    fail(){}
    13.  });
    14. }

  2. 获取第三方小程序返回值

     //app.js
 App({
   onShow(options){
     console.log("onShow", options);
     if(options.referrerInfo){
       console.log("第三方小程序返回", options.referrerInfo.extraData.returnObj);
     }

  3. 接收参数

    Page({
  onLoad: function (options) {
     console.log("onLoad 初始化数据: ", options)
     let that = this
     let data = {}
     if (options.q) {
         // 1. 线上小程序主动传参
         data = signUtil.getUrlParam(decodeURIComponent(options.q));
         console.log("1. 参数载体-小程序页面传参: options.q");
     }
 }
})

  4. 返回调用方

     let that = this
 console.log(that.scene)
 console.log("返回小程序")
 // 返回小程序
 my.navigateBackMiniProgram({
     // 目标小程序可在 App.onLaunch()、App.onShow() 中获取到这份数据
     extraData: that.extraData,
     success: (res) => {
         console.log(JSON.stringify(res))
     },
     fail: (res) => {
         console.log(JSON.stringify(res))
     }
 });
