核心代码就两处

main.js

拦截关于websocket的js文件把请求转给本地代理服务器

// 拦截请求
this.webContents.session.webRequest.onBeforeRequest((details, callback) => {

    // 在这里进行请求处理，例如修改请求 URL、添加请求头等
    if (
        /^https:\/\/.+?webcast\/douyin_live\/\d+.+\.js$/.test(details.url)
    ) {
        callback({ redirectURL: `http://localhost:${replaceWsPort}/${details.url}` });
        return
    }
    
    // 继续请求
    callback({ cancel: false });
});

replaceWs.js

本地代理服务拿到js文件，对js文件修改加hook

// http拿到js文件内容
return fetch(url).then(res => res.text()).then(text => {
    // 是否有ws字样
    if (!text.includes('new WebSocket')) return text
    // 开始替换数据
    // 替换onError
    text = text.replaceAll(/(\{.+?\("socket error",(.+?)\),)/g, '$1typeof window.emitClose == \'function\' && window.emitClose(\'error\',$2),')
    // 替换onClose
    text = text.replace(/(\{.+?\("socket closed",(.+?)\),)/, '$1typeof window.emitClose == \'function\' && window.emitClose(\'close\',$2),')
    // 替换onOpen td("socket established"),
    text = text.replace(/(\{.+?\("socket established"\),)/, '$1typeof window.emitOpen == \'function\' && window.emitOpen(),')
    // 替换onMessage ;eu || tM("no payload can be decoded, maybe cannot find idl", eo);
    text = text.replace(/;([a-zA-Z]+)?\|\|.+?\("no payload can be decoded, maybe cannot find idl",[a-zA-Z]+\);/, ';if(typeof window.emitMessage == \'function\'){window.emitMessage($1);}return {method:\'\'};')
    // 替换stop函数
    // text = text.replace(/\{[a-zA-Z]+?\("socket terminating"\),/, '{return;')
    text = text.replaceAll(/stop\(\)\s*\{/g, 'stop(){return;')
    // 替换 "visible"
    text = text.replaceAll(/"visible"/g, '"_visible_"')
    // 替换暂停 pause() {
    text = text.replaceAll(/pause\(\)\s*\{/g, 'pause() {return;')
    return text
})

然后你懂得...
