1.定義好pay.wxml

<view class='btn_box'>
          <navigator target='miniProgram' extra-data='{{extraData}}' path='pages/index/index' app-id='wxbd687630cd02ce1d' hover-class="none">
            <view class='btn_btn nor_linear_bg'>開通免密支付</view>
          </navigator>
        </view>
 

2.設定好pay.js引數處理

var util = require('../../utils/util.js');
const app = getApp();
Page({

  onShow: function (options) {
    console.log(options,'pay.js start');
        
  },
  data:{
      extraData:'',
      localCity:''
  },
  onLoad: function() {
      this.setData({
          extraData:util.getextraData(),
          localCity:wx.getStorageSync(util.key.cityName) || app.globalData.baseInfo.cityName
      })
  }
})
 

繫結免密簽證引數設定：

function getextraData() {
  const app = getApp();
  var extraDataValue = {
    appid: app.globalData.baseInfo.appId,
    mch_id: app.globalData.baseInfo.mchId,
    sub_mch_id: app.globalData.baseInfo.subMchId,
    notify_url: app.globalData.baseInfo.notifyUrl,
    contract_code: config.contractCode,
    contract_display_account: app.globalData.baseInfo.contractDisplayAccount,
    plan_id: app.globalData.baseInfo.planId,
    request_serial: config.requestSerial,
    timestamp: config.timestamp,
    sub_appid: app.globalData.baseInfo.subAppId
  };
  var extraDataSortValue = getSort(extraDataValue);
  var signValue = getSign(extraDataSortValue, app.globalData.baseInfo.appSecret);
  extraDataValue['sign'] = signValue;
  log(TAG, "signSign=[" + signValue + "]length=" + String(signValue).length);
  return extraDataValue;
}
 

例如：

3.app.js中 處理繫結後返回值

onShow: function (options) {
    let that = this;
    var bindStatus = wx.getStorageSync(util.key.bindStatus) || 0;
      if (options.scene == 1038) {
        var errorCode = options.referrerInfo && options.referrerInfo.extraData && options.referrerInfo.extraData.return_code ? options.referrerInfo.extraData.return_code:'';
        if (errorCode == 'SUCCESS') {
          var appid = options.referrerInfo.appId;
          var contractId = options.referrerInfo.extraData.contract_id;
          console.log("簽約成功");
          that.globalData.baseInfo.appid = appid;
          that.globalData.baseInfo.contractId = contractId;
          that.globalData.baseInfo.contractIds = contractId;
          that.globalData.baseInfo.bindStatus = 1;
          wx.setStorageSync(util.key.bindStatus, 1);
          
          //add by wupeng for jump scan
          //認證繫結後通過navigateBack跳轉到首頁scan可以直接退出
          var pagelist = getCurrentPages();
          var len = pagelist.length;
          var init = 0;
          var index = 0;
          for (var i = 0; i < len; i++) {
            if (pagelist[i].route.indexOf("scan/scan") >= 0) {//看路由裡面是否有首頁
              init = 1;
              index = i;
            }
          }
          if (init == 1) {
            wx.navigateBack({
              delta: len - index - 1
            });
          } else {
            wx.reLaunch({
              url: "../scan/scan"//這個是預設的單頁
            });
          }
          //end add by wupeng 20180921


        } else {
          var msg = options.referrerInfo.extraData.return_msg;
          wx.showModal({
            title: errorCode,
            content: msg,
          });
          console.log(TAG + ':簽約失敗');
        }
      }
    // }
  },
