第一步：切换登陆方式

第二步：查看抓包情况

第三步：模拟登陆后抓包

查看发包参数，本次主要处理password这个参数



l是对字符串处理的方法


可以看出先对原密码进行了加密，然后用l方法对密码又进行了处理
将代码添加到浏览器的Overrides,方便改写调试
第四步：改写js并进行分析

var aaa;
!function(n) {
    var r = {};
    function i(t) {
        if (r[t])
            return r[t].exports;
        var e = r[t] = {
            i: t,
            l: !1,
            exports: {}
        };
        return n[t].call(e.exports, e, e.exports, i),
        e.l = !0,
        e.exports
    }
    i.m = n,
    i.c = r,
    i.d = function(t, e, n) {
        i.o(t, e) || Object.defineProperty(t, e, {
            enumerable: !0,
            get: n
        })
    }
    ,
    i.r = function(t) {
        "undefined" != typeof Symbol && Symbol.toStringTag && Object.defineProperty(t, Symbol.toStringTag, {
            value: "Module"
        }),
        Object.defineProperty(t, "__esModule", {
            value: !0
        })
    }
    ,
    i.t = function(e, t) {
        if (1 & t && (e = i(e)),
        8 & t)
            return e;
        if (4 & t && "object" == typeof e && e && e.__esModule)
            return e;
        var n = Object.create(null);
        if (i.r(n),
        Object.defineProperty(n, "default", {
            enumerable: !0,
            value: e
        }),
        2 & t && "string" != typeof e)
            for (var r in e)
                i.d(n, r, function(t) {
                    return e[t]
                }
                .bind(null, r));
        return n
    }
    ,
    i.n = function(t) {
        var e = t && t.__esModule ? function() {
            return t.default
        }
        : function() {
            return t
        }
        ;
        return i.d(e, "a", e),
        e
    }
    ,
    i.o = function(t, e) {
        return Object.prototype.hasOwnProperty.call(t, e)
    }
    ,
    i.p = "/",
    i(i.s = 20)
    aaa=i
}

定义一个全局变量，把加载器赋值到全局变量，查看该变量

控制台打印输出，可以看出导出了59个方法

加密位置

所有代码：
js太多，放图片代替

aaa(50).default();

// console.log(ddd);
function get_pw(mm) {

    var e = "MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCCB81pk1Go/d7K8unYqeB6YyQdDgIRsLji7BxlBfMC2U8/0lyOLxJ6sQb1RmKaILuxN0hRci4zWPfkkPhttWaogq3XABYiDYbx0843ge4D79pG21+qWplw43uHZNs0B6iUChJW1O3DDJPXGwj50L1ySTVt7G7iqsIr9PLZVRSZmQIDAQAB"
    ddd.ec.setPublicKey(e)
    // ddd.loginTicketId = ""
    ddd.publicKey = e
    // ddd.encodeVersion = "2.0"
    console.log(ddd.ec.encrypt(mm))
    return ddd.ec.encrypt(mm)
}

最后一步：模拟请求

import json
import requests
import execjs

headers = {
    "Accept": "application/json, text/plain, */*",
    "Accept-Encoding": "gzip, deflate, br",
    'Accept-Language': 'zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6',
    'Content-Type': "application/json;charset=UTF-8",
    "Host": "clogin.ke.com",
    'Origin': 'https://su.ke.com',
    "Referer": "https://su.ke.com",
    "sec-ch-ua-platform": "Windows",
    'Sec-Fetch-Dest': 'empty',
    'Sec-Fetch-Mode': 'cors',
    'Sec-Fetch-Site': 'same-site',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/102.0.0.0 Safari/537.36',
}

data = {"service": "https://ajax.api.ke.com/login/login/getuserinfo", "version": "2.0"}

# response = requests.post("https://clogin.ke.com/authentication/initialize", headers=headers, data=json.dumps(data))
response = requests.post("https://clogin.ke.com/authentication/initialize", headers=headers, json=data)
# print(response.json())

# 知识点
# 如果参数为JSON数据，可以直接传⼊json参数，它将⾃动编码并将Content-Type的置为application/json

# 如果data传递的参数为字符串，例如【json.dumps(payload)】，则request对参数进⾏url编码,Content-Type的值为None,所以
# data传字符串时，⼀定要在header中指定Content-Type为application/json

# 如果data传递的是字典、元组组成的列表或列表作为值的字典，则request对参数进⾏url编码，Content-Type的值为
# application/x-www-form-urlencoded

password = execjs.compile(js_str).call("get_pw", "asd123456")
