逆向过程 


请求方式:POST

逆向参数

        sign zzbd8c72309rdslvlnjwk8pthj2lw462f12d2

过程分析

根据XHR断点方式可快速进入发包内容

 向上找入口函数, 折叠可知该函数【B】存在我们需要的参数

// queryString 参数1 _
if (e.url = C({
     _: Date.now()
}, e.url)


// queryString 参数2 sign
e.url = C({
    sign: i
}, e.url)

那么定位到这里可知,只需要定位到参数【i】即可完成本次逆向

var i, o = n(147).default;
i = "GET" === e.type.toUpperCase() ? o(e.data.data) : o(e.data),

断点调试

断点可知:

【e.data】 POST请求参数

 【o】方法则为 webpack导出后执行  ****************

                    r += "0123456789abcdef".charAt(e >>> 4 & 15) + "0123456789abcdef".charAt(15 & e);

        var i = n._getSecuritySign;
        delete n._getSecuritySign,
        e.default = i
    }
    .call(this, n(110))
}

由调试可知方法: n(110)  ===  window

, function(t, e) {
    var n;
    n = function() {
        return this
    }();
    try {
        n = n || new Function("return this")()
    } catch (r) {
        "object" === typeof window && (n = window)
    }
    t.exports = n
}

扣取代码

断点单步进入【o】内部

快速折叠方法 后拉到文件最顶部可知该方式为 webpack 加载

(window.webpackJsonp = window.webpackJsonp || []).push([[0], [, function(t, e, n) {

 那么回到调取执行方法部内,我们发现 加载函数【n(110)】打上断点,或在上下函数中找方法【n】进行断点进入
