DQ（v3.0.220723)网页加载速度优化

wuxiandianzi · 发表于 2023-12-23 21:24:16

大家有没有发现一个问题：

setTimeout(function() {
var appid = '';
var channelname = window.location.hostname;
if (!!window.navigator.userAgent.match(/AppleWebKit.*Mobile.*/)) {
appid = '500D36509CE649E88446FB4E7A51B221'; // h5
} else {
appid = '4F323A1D5F444BF69C7C4E10704AEA2F'; // pc
}
var url = 'http://sdk.talkingdata.com/app/h5/v1?appid=' + appid + '&vn=' + 'v3.0.220113' + '&vc=' + 'v3.0.220113' + '&td_channelid=' + channelname;
if ( window.location.protocol.indexOf('https') != -1 ) {
url = 'https://jic.talkingdata.com/app/h5/v1?appid=' + appid + '&vn=' + 'v3.0.220113' + '&vc=' + 'v3.0.220113' + '&td_channelid=' + channelname;
}
var talkingdata = document.createElement('script');
talkingdata.type = 'text/javascript';
talkingdata.async = true;
talkingdata.src = url;
document.getElementsByTagName('body')[0].appendChild(talkingdata);
window.sessionStorage.setItem('__TD_td_channel', window.location.hostname.replace(/./g, '_'));
var tdjs = document.createElement('script');
tdjs.type = 'text/javascript';
tdjs.async = true;
tdjs.src = 'https://jic.talkingdata.com/app/h5/v1?appid=750AEE91CF4446A19A2D12D5EE32F725';
document.getElementsByTagName('body')[0].appendChild(tdjs);
var dzqjs = document.createElement('script');
dzqjs.type = 'text/javascript';
dzqjs.async = true;
dzqjs.src = '/js/dzq.js';
document.getElementsByTagName('body')[0].appendChild(dzqjs);
}, 2000);

复制代码

这个引用有153个，涉及文件78个
仔细阅读发现，这个function 是判断客户端的浏览器类型，以及针对不同浏览器创建不同的js文件

试想一下，如果离线或者网络不通情况下，是不是会延迟网络加载速度，虽然代码里写的是异步访问，但是随着时间的推移，网络后台缓存会不断尝试连接并报错！

不知道开发者当时的设计思路，为什么不调用本地的js呢？而且78个文件中都有这个调用，为什么不引用一个公共函数？

昨天我翻电脑，找到了官方最后一个版本的安装包，尝试修改了其中的js文件调用，现在只有上面代码中提到的2个链接，经过试验发现，正常安装，而且页面打开速度很快

刚刚尝试把代码中的js文件保存到本地，修改成本地调用后，现在打开首页速度稳定在0.05秒，可怕不？

对了还有一个大家不知道的代码：

img.src = "https://discuzq-0gxi1bn2969fa48d.service.tcloudbase.com/access?" + pt + "&dn=" + encodeURIComponent(window.location.hostname.replace(/\./g, "_"));

复制代码

这个是引用的图片，居然是一个点，每次开页面都回访问，不知道官方是统计访问次数还是？不得而知。

还是那句话，接触discuz已经10多年了，没有感情是不可能的，虽然DQ停止了维护，但是不能把摊子直接甩掉吧？很伤感情。

复制代码

http://sdk.talkingdata.com/app/h5/v1?appid=500D36509CE649E88446FB4E7A51B221&vn=v3.0.220113&vc=v3.0.220113&td_channelid=127.0.0.1

复制代码

访问上面这个地址会返回这个：

var appid = '500D36509CE649E88446FB4E7A51B221';
var vn = 'v3.0.220113';
var vc = 'v3.0.220113';
var TDBaseUrl = 'http://sdk.talkingdata.com/app/h5/v1/websdk';
var TDRequestUrl = 'http://h5data.talkingdata.net/app/v1';
function createScriptTd(url) {
var _head = document.getElementsByTagName('head')[0];
var _script = document.createElement('script');
_script.type = 'text/javascript';
_script.src = url;
_head.appendChild(_script)
};
createScriptTd(TDBaseUrl + '/js/sdk_release.js');
if (!window['JSON'] || typeof JSON !== 'object') {
createScriptTd(TDBaseUrl + '/js/json2.js')
};
window["TDAPP"] = {};
window["TDAPP"].onEvent = function (id, label, params) {
if (arguments.length > 0) {
try {
var opts = {
count: 1,
start: new Date().getTime()
};
if (id != undefined) {
opts["id"] = typeof id != "string" ? JSON.stringify(id) : id
}
if (label != undefined) {
opts["label"] = typeof label != "string" ? JSON.stringify(label) : label
} else {
opts["label"] = ""
}
if (params != undefined) {
var isJson = function (obj) {
var isjson = typeof(obj) == "object" && Object.prototype.toString.call(obj).toLowerCase() == "[object object]" && !obj.length;
return isjson
};
if (isJson(params)) {
opts["params"] = params
} else {
opts["params"] = {
params: ""
}
}
}
var eventName = "__TD_td-init-event";
var ev = localStorage[eventName];
if (ev) {
var ca = JSON.parse(ev);
ca.push(opts);
localStorage.setItem(eventName, JSON.stringify(ca));
return
};
localStorage.setItem(eventName, "[" + JSON.stringify(opts) + "]")
} catch (e) {}
}
};

复制代码

注意上述代码中会执行创建以下js文件：
TDRequestUrl=http://h5data.talkingdata.net/app/v1

TDBaseUrl=http://sdk.talkingdata.com/app/h5/v1/

http://sdk.talkingdata.com/app/h5/v1/websdk/js/sdk_release.js
http://sdk.talkingdata.com/app/h5/v1/websdk/js/js/json2.js

经过合并后会得到sdk_release.js，那么是否可以在此处直接根据条件引用本地js呢？

同理访问：

https://jic.talkingdata.com/app/h5/v1?appid=750AEE91CF4446A19A2D12D5EE32F725

复制代码

会返回：

var appid = '750AEE91CF4446A19A2D12D5EE32F725';
var vn = '';
var vc = '';
var TDBaseUrl = 'https://jic.talkingdata.com/app/h5/v1/websdk';
var TDRequestUrl = 'https://h5.udrig.com/app/v1';
function createScriptTd(url) {
var _head = document.getElementsByTagName('head')[0];
var _script = document.createElement('script');
_script.type = 'text/javascript';
_script.src = url;
_head.appendChild(_script)
};
createScriptTd(TDBaseUrl + '/js/sdk_release.js');
if (!window['JSON'] || typeof JSON !== 'object') {
createScriptTd(TDBaseUrl + '/js/json2.js')
};
window["TDAPP"] = {};
window["TDAPP"].onEvent = function (id, label, params) {
if (arguments.length > 0) {
try {
var opts = {
count: 1,
start: new Date().getTime()
};
if (id != undefined) {
opts["id"] = typeof id != "string" ? JSON.stringify(id) : id
}
if (label != undefined) {
opts["label"] = typeof label != "string" ? JSON.stringify(label) : label
} else {
opts["label"] = ""
}
if (params != undefined) {
var isJson = function (obj) {
var isjson = typeof(obj) == "object" && Object.prototype.toString.call(obj).toLowerCase() == "[object object]" && !obj.length;
return isjson
};
if (isJson(params)) {
opts["params"] = params
} else {
opts["params"] = {
params: ""
}
}
}
var eventName = "__TD_td-init-event";
var ev = localStorage[eventName];
if (ev) {
var ca = JSON.parse(ev);
ca.push(opts);
localStorage.setItem(eventName, JSON.stringify(ca));
return
};
localStorage.setItem(eventName, "[" + JSON.stringify(opts) + "]")
} catch (e) {}
}
};

如果把引用改为访问本地的两个js文件，是不是速度会快很多很多？
试验发现，验证了猜想。

其实原版的DQ3 还有很多js文件调用，统统改为本地文件，不管网络问题还是离线问题，而且首页和编辑器很快可以代开。
这里班门弄斧了，DQ 需要优化的地方太多了，DQ的初衷是为了配合腾讯云的产品吧，所以一切都需要联网，我还停留在discuz那种思维中，这里犯了错误。

你好，最近正好碰到网页加载突然变慢的情况。版本就是3.0 220723 ，印象中只是在尝试SEO设置的设置过SSR功能，不知道会不会跟这个有关？朋友，能帮我查下原因么，我是完全的技术小白，但是使用discuzQ搭建的网站已经稳定运行1年。https://discuz.spaceguests.com ，哪位高人能帮我看看，分析下加载速度慢的原因么？

对的，不过是一年操作的了，也不是记得十分清楚，可以使用xbuilder或者微信开发者工具。我现在这几天貌似速度又正常了，还挺奇怪的。
