花费了两天时间，修改过数次，终于把这个功能封装成了一个独立的工具。
任何小程序都可在不修改原代码的情况下直接镶入使用！！！
步骤：
1. 在小程序 app.js 的平级目录创建一个 js ， 命名为 userTrajectory.js。点击下载
userTrajectory.js 实现的代码是把 ‘存储用户在当前小程序的操作日志。然后传给后端’ 封装起来。
2.在 app.js 内引用 userTrajectory.js ，并且把当前对象赋值给 userTrajectory.js 。示例代码：
var userTrajectory = require('./userTrajectory.js');
App({ onLaunch: function(options) { //获取用户操作轨迹 userTrajectory.initUserTrajectory.apply(this, []); }})
3.在小程序内调用它。使用代码示例：
Page({ data: { }, onLoad: function (options) { //opType = '操作类型', opEvent = '操作事件',opEventId = '操作事件ID',opnEventDetail = '操作事件详情' getApp().getUserTrajectory(1, 'onLoad', 'pages/index_0', '进入小程序首页');//获取用户轨迹 }})
4.完成。用户操作轨迹的日志 log：
传给后端的数据参数说明：
参数 参数说明
pagePath 页面路径
intoId 进入小程序的场景值ID
originId 来源ID
userToken 用户标识
upTime 上传信息的时间戳
userTrajectoryArr 用户操作轨迹的数组
userTrajectoryArr 数组内的对象（用户在小程序里面进行的所有操作都保存在这）：
参数 参数说明
opTime 操作的时间戳
opType 操作类型
opEvent 操作事件
opEventId 操作事件ID
opnEventDetail 操作事件详情
opType - 操作类型详细说明：
1.页面跳转 2.支付 3.分享小程序 4.跳转小程序
5.页面内点击 6.自定义 7.用户输入 8.拨打客服电话
996.小程序显示 997.小程序隐藏 998.小程序销毁 999.进入小程序调用示例：
getApp().getUserTrajectory(1, 'onLoad', 'pages/index_0', '进入小程序首页');//获取用户轨迹数据格式示例： appQuery:{}intoId:1001originId:undefineduserToken:o3XPM4q-4F1IfEYDnBFt2tLZHQ5EupTime:1546499501918userTrajectoryArr: [ {"opTime":1546499472740,"opType":6,"opEvent":"Require","opEventId":"pages/OrderList/orderHistory/orderHistory_10","opnEventDetail":"订单记录页面请求订单接口","params1":"","params2":"","params3":""},{"opTime":1546499495706,"opType":999,"opEvent":"AppOnLaunch","opEventId":"app.js_0","opnEventDetail":"小程序启动","params1":"","params2":"","params3":""},{"opTime":1546499495814,"opType":996,"opEvent":"AppOnShow","opEventId":"app.js_1","opnEventDetail":"小程序显示","params1":"","params2":"","params3":""},{"opTime":1546499495876,"opType":1,"opEvent":"onLoad","opEventId":"pages/index_0","opnEventDetail":"进入小程序首页","params1":"","params2":"","params3":""},{"opTime":1546499498787,"opType":1,"opEvent":"navigate","opEventId":"pages/index_3","opnEventDetail":"跳转到订单记录页面","params1":"","params2":"","params3":""},{"opTime":1546499499417,"opType":1,"opEvent":"onLoad","opEventId":"pages/OrderList/orderHistory/orderHistory_0","opnEventDetail":"进入订单记录首页","params1":"","params2":"","params3":""},{"opTime":1546499499454,"opType":6,"opEvent":"Require","opEventId":"pages/OrderList/orderHistory/orderHistory_10","opnEventDetail":"订单记录页面请求订单接口","params1":"","params2":"","params3":""},{"opTime":1546499501042,"opType":6,"opEvent":"Require","opEventId":"pages/OrderList/orderHistory/orderHistory_10","opnEventDetail":"订单记录页面请求订单接口","params1":"","params2":"","params3":""},{"opTime":1546499501478,"opType":6,"opEvent":"Require","opEventId":"pages/OrderList/orderHistory/orderHistory_10","opnEventDetail":"订单记录页面请求订单接口","params1":"","params2":"","params3":""} ]
