逆向分析

补环境代理

function get_enviroment(proxy_array) {for (var i = 0; i < proxy_array.length; i++) {handler = '{\n' +'    get: function(target, property, receiver) {\n' +'        console.log("方法:", "get  ", "对象:", ' +'"' + proxy_array[i] + '" ,' +'"  属性:", property, ' +'"  属性类型:", ' + 'typeof property, ' +// '"  属性值:", ' + 'target[property], ' +'"  属性值类型:", typeof target[property]);\n' +'        return target[property];\n' +'    },\n' +'    set: function(target, property, value, receiver) {\n' +'        console.log("方法:", "set  ", "对象:", ' +'"' + proxy_array[i] + '" ,' +'"  属性:", property, ' +'"  属性类型:", ' + 'typeof property, ' +// '"  属性值:", ' + 'target[property], ' +'"  属性值类型:", typeof target[property]);\n' +'        return Reflect.set(...arguments);\n' +'    }\n' +'}'eval('try{\n' + proxy_array[i] + ';\n'+ proxy_array[i] + '=new Proxy(' + proxy_array[i] + ', ' + handler + ')}catch (e) {\n' + proxy_array[i] + '={};\n'+ proxy_array[i] + '=new Proxy(' + proxy_array[i] + ', ' + handler + ')}')}
}
// get_enviroment(proxy_array)

部分补环境代码

History = function () {
}
Object.defineProperties(History.prototype, {[Symbol.toStringTag]: {value: "History",writable: true,enumerable: false,configurable: true}
})
history = {length: 4,scrollRestoration: "auto",state: null,
}
Object.defineProperty(window, 'queueMicrotask', {configurable: true,
enumerable: true,
value: function queueMicrotask(){},
writable: true
})
Object.defineProperty(window, 'structuredClone', {configurable: true,
enumerable: true,
value: function structuredClone(){},
writable: true
})
Object.defineProperty(window, 'crypto', {configurable: true,
enumerable: true,get:function crypto() {return {subtle:{}}},set:undefined
})window.matchMedia = function (val) {console.log('window.matchMedia', arguments)if (val == '(min-width: 1535px)') {return {matches: false,media: val,onchange: null,}}debugger;
}
this.func_set_natvie(window.matchMedia)
Object.defineProperty(window,'DOMParser', {configurable: true,enumerable: false,value: function DOMParser() {},writable: false
})
Object.defineProperty(window,'fetch', {configurable: true,enumerable: false,value: function fetch() {},writable: true
})
扣代码调用加密

_token = decodeURIComponent(atob(env))
_token = window.q3(_token,request_code,false)

结果

总结

 1.出于安全考虑,本章未提供完整流程,调试环节省略较多,只提供大致思路,具体细节要你自己还原,相信你也能调试出来。
