題目1：抓取所有（5頁）機票的價格，並計算所有機票價格的平均值，填入答案。

由於專注點並不在js逆向上，所以js逆向可能並不不好. 各位看官看看就好了喲~

初步分析

進入網站, 習慣性的開啟了F12, 直接給debug住, 這裡直接用Conditional breakpoints

不知道是什麼的同學參考這篇文章.https://blog.csdn.net/Qiled/article/details/109610726 搜尋Conditional breakpoints即可.

在這裡插入圖片描述
抓包可以很容易的猜到，這題的考點就是這個m值. 把m值解決了,就啥都解決了~

關鍵點定位

通過callstack可以定位到以下程式碼

var m=oo0O0(timestamp.toString())+window.f;
var list={"page":window.page,"m":m+'丨'+timestamp/1000}

在這裡插入圖片描述

初次嘗試

已經知道 oo0O0 函式是關鍵, 那麼我們可以通過控制檯來拿到這個函式程式碼

oo0O0 + ''

自然而然的就把程式碼統統都吐了出來

function oo0O0(mw) {
    window.b = '';
    for (var i = 0, len = window.a.length; i < len; i++) {
        console.log(window.a[i]);
        window.b += String[document.e + document.g](window.a[i][document.f + document.h]() - i - window.c)
    }
    var U = ['W5r5W6VdIHZcT8kU', 'WQ8CWRaxWQirAW=='];
    var J = function(o, E) {
        o = o - 0x0;
        var N = U[o];
        if (J['bSSGte'] === undefined) {
            var Y = function(w) {
                var m = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789+/='
                  , T = String(w)['replace'](/=+$/, '');
                var A = '';
                for (var C = 0x0, b, W, l = 0x0; W = T['charAt'](l++); ~W && (b = C % 0x4 ? b * 0x40 + W : W,
                C++ % 0x4) ? A += String['fromCharCode'](0xff & b >> (-0x2 * C & 0x6)) : 0x0) {
                    W = m['indexOf'](W)
                }
                return A
            };
            var t = function(w, m) {
                var T = [], A = 0x0, C, b = '', W = '';
                w = Y(w);
                for (var R = 0x0, v = w['length']; R < v; R++) {
                    W += '%' + ('00' + w['charCodeAt'](R)['toString'](0x10))['slice'](-0x2)
                }
                w = decodeURIComponent(W);
                var l;
                for (l = 0x0; l < 0x100; l++) {
                    T[l] = l
                }
                for (l = 0x0; l < 0x100; l++) {
                    A = (A + T[l] + m['charCodeAt'](l % m['length'])) % 0x100,
                    C = T[l],
                    T[l] = T[A],
                    T[A] = C
                }
                l = 0x0,
                A = 0x0;
                for (var L = 0x0; L < w['length']; L++) {
                    l = (l + 0x1) % 0x100,
                    A = (A + T[l]) % 0x100,
                    C = T[l],
                    T[l] = T[A],
                    T[A] = C,
                    b += String['fromCharCode'](w['charCodeAt'](L) ^ T[(T[l] + T[A]) % 0x100])
                }
                return b
            };
            J['luAabU'] = t,
            J['qlVPZg'] = {},
            J['bSSGte'] = !![]
        }
        var H = J['qlVPZg'][o];
        return H === undefined ? (J['TUDBIJ'] === undefined && (J['TUDBIJ'] = !![]),
        N = J['luAabU'](N, E),
        J['qlVPZg'][o] = N) : N = H,
        N
    };
    eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), '\x27' + mw + '\x27'));
    return ''
}

然後把程式碼放到瀏覽器去執行一下.不用想，絕對是會報錯的！
在這裡插入圖片描述
報錯的是 window.a.length , 那麼我們就去看看window.a是個啥~

window.a='isMRQsxrU]xtDhMbZ‹JrrdƒvˆxP„ii......' // 此處省略許許多多的字串

補充到瀏覽器上, 除錯又報出缺少document.e,f等錯誤. 繼續補全

document.e='fromC';document.f='charCo';document.g='harCode';document.h='deAt';

繼續除錯

// Uncaught DOMException: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.
eval(atob(window['b'])[J('0x0', ']dQW')](J('0x1', 'GTu!'), '\x27' + mw + '\x27'));

在猿人學的官網上執行下程式碼atob(window['b'])拿到資料

怎麼樣， 很熟悉的MD5.

然後再看看 J('0x1','GTu!')是什麼.瀏覽器執行一下。

                    T[A] = C,
                    b += String['fromCharCode'](w['charCodeAt'](L) ^ T[(T[l] + T[A]) % 0x100])
                }
                return b
            };
            J['luAabU'] = t,
            J['qlVPZg'] = {},
            J['bSSGte'] = !![]
        }
        var H = J['qlVPZg'][o];
        return H === undefined ? (J['TUDBIJ'] === undefined && (J['TUDBIJ'] = !![]),
        N = J['luAabU'](N, E),
        J['qlVPZg'][o] = N) : N = H,
        N
    };

再次執行

J('0x1','GTu!')
// "mwqqppz"

那麼，其實下面的程式碼可以分割成


eval(
atob(window['b'])[J('0x0', ']dQW')] // replace
    (
        J('0x1', 'GTu!'), // "mwqqppz"
        '\x27' + mw + '\x27' // mw 是傳入的時間
    )

);

等價於

"上面的md5程式碼".replace( "mwqqppz",mw )

最後我們還驚奇的發現,這個oo0O0方法返回的是空. 但是別忘記了window.f

var m=oo0O0(timestamp.toString())+window.f;
var list={"page":window.page,"m":m+'丨'+timestamp/1000};

在window.b的程式碼中， 可以看到這麼一行程式碼

window.f = hex_md5(mwqqppz)

然而我們上面已經把mwqqppz替換成了時間戳。 結果就出來了~

總結流程

第一題其實就是

  1. 把 var timestamp=Date.parse(new Date()); wm = timestamp.toString()這個wm進行一個md5 加密
  2. 再拼湊一番~ m + '丨'+timestamp/1000
