出于运营的需要,我们需要将页面的流转信息,用户点击分布,错误,页面渲染情况发送到后端
小程序编译阶段,会将所有事件转换为一个全局的dispatchEvent方法,因此我们可以这里做统一的日志的收集
<div onclick="dispatchEvent" data-beacon-uid="clickForVibration" class="item" data-click-uid="e1765" data-class-uid="c1321">
<text>震动</text>
</div>
如果我们发现这事件类型是click/tap/change/blur, 我们就会为这些元素添加一个data-beacon-uid
, 值为default,(如果你已经写了,它就不会添加),然后在dispatchEvent执行app.js的全局对象的onCollectLogs
方法,让用户整理成一个对象,放到一个数组中, 并尝试使用onReportLogs
自动发送;
//dispatchEvent的源码
export function dispatchEvent(e) {
const instance = this.reactInstance;
if (!instance || !instance.$$eventCached) {
return;
}
const eventType = toLowerCase(e.type);
const app = _getApp();
const target = e.currentTarget;
const dataset = target.dataset || {};
const eventUid = dataset[eventType + 'Uid'];
const fiber = instance.$$eventCached[eventUid + 'Fiber'] || {
props: {},
type: 'unknown'
};
if (app && app.onCollectLogs && /click|tap/.test(eventType) ) {
app.onCollectLogss(dataset, eventType, fiber && fiber.stateNode);
}
//....略
}
当用户退出APP时,会进入onHide事件,这时我们就会上传剩余的所有日志
因此用户只需要在app.js定义好这两个事件,框架帮你搞定日志上传。下面是示例:
import React from '@react';
import './pages/index/index';
import './pages/demo/base/index';
import './pages/demo/native/index/index';
import './app.scss';
function computeXpath(node){ //通过xpath实现自动埋点
var xpath = [];
while (node.parentNode){
var index = node.parentNode.children.indexOf(node);
var tag = node.type == 'div' ? 'view': node.type;
xpath.unshift(tag+'['+index+']');
node = node.parentNode;
}
return '/page/'+ xpath.join('/');
}
function computeCompressedXpath(node){ //压缩后的xpath
var xpath = [];
while (node.parentNode){
var index = node.parentNode.children.indexOf(node);
xpath.unshift(index);
node = node.parentNode;
}
return xpath.join('/');
}
var openChange = false;
class Global extends React.Component {
static config = {
window: {
backgroundTextStyle: 'light',
navigationBarBackgroundColor: '#0088a4',
navigationBarTitleText: 'mpreact',
navigationBarTextStyle: '#fff'
}
};
// 全局数据
globalData = {
ufo: 'ufo'
};
onCollectLogs(dataset, eventType, node){ //这里会在框架的dispatchEvent自动调起,实现自动理点
var beaconId = dataset.beaconUid;
if( beaconId == 'default' && node ){
beaconId = computeCompressedXpath(node);
}
if (eventType === 'input') {//input事件触发太频繁了,我们只想收集一次
if (openChange) return;
openChange = true;
setTimeout(() => {
openChange = false;
}, 1000);
}
var otherData = dataset.xxx//data-xxxx
var otherData2 = dataset.xxx2;
var timeStamp = new Date - 0;
var path = React.getCurrentPage().props.path;//页面路径
var logs = this.globalData.logs || (this.globalData.logs = [])
logs.push({
pid: beaconId,
path: path,
timeStamp: timeStamp
action: eventType
});
if(logs.length > 20){
var uploadLogs = logs.splice(0, 10);//截取前十条;
if(this.onReportLogs){
this.onReportLogs(uploadLogs)
}
}
};
onHide(){
this.onReportLogs(); //微信,支付宝,百度
};
onDistory(){
this.onReportLogs(); //快应用
};
onReportLogs(logs){ //自己实现
if(!logs){
var existLogs = this.globalData.logs
if(!Array.isArray(existLogs) || existLogs.length == 0){
return
}
logs = existLogs;
this.globalData.logs = [];
}
if(!logs.length){
return
}
var buildType = this.globalData.buildType;// wx, bu, ali
var info = this.globalData.systemInfo | React.api.getSystemInfornSync();
var { brand, model, version, platform} = info ;//获取手机品牌,手机型号, 微信版本号, 客户端平台;
React.api.request({
url: "/fdsfdsf/sdfds",
type: 'GET',
data: {
logs, //logData
buildType,//wx, bu, ali, quick, tt, qq
brand, //commonData
model, //commonData
version,//commonData
platform,//commonData
//other
}
})
},
onLaunch() {
console.log('App launched');
}
}
export default App(new Global());
在common目录下
import React from '@react'
//此方法用于手动埋点
function createLog(dataset, eventType){
var app = React.getApp();
if(typeof app.onCollectLogs === 'function' ){
app.onCollectLogs(dataset, eventType, null)
}
}
