小程序确认收货

//点击确认收货按钮。
wx.openBusinessView({
  businessType: 'weappOrderConfirm',
  extraData: {
    merchant_id: merchant_id,
    merchant_trade_no: order_no,
    transaction_id: transaction_id
  },
  success() {
    
  },
  fail() {
    
  },
  complete() {
  }
});

首页app.js里的onShow

onShow(options) {
    if(options.referrerInfo && options.referrerInfo.extraData && options.referrerInfo.extraData.req_extradata){
      let t_status = options.referrerInfo.extraData.status
      let req_extradata = options.referrerInfo.extraData.req_extradata
      if(t_status=="success"){
        
      }
    }
}
