某單位組織員工開展健步走活動(dòng)，由于策略限制，必須使用傳統(tǒng)計(jì)步器或者手機(jī)APP的方式記錄行走步數(shù)，且APP必須始終處于運(yùn)行狀態(tài)方能計(jì)步，這種不合理的方式嚴(yán)重影響了客戶體驗(yàn)，但是這一切的一切都沒法改變，所以想著能不能通過修改數(shù)據(jù)包的方式完成步數(shù)的刷新上傳。

使用Charles對(duì)上傳的數(shù)據(jù)進(jìn)行分析

由于是通過手機(jī)APP的記錄并上傳行走步數(shù)，因此采用比較易用和好用的Charles抓包工具對(duì)APP上傳的數(shù)據(jù)包進(jìn)行分析
為了避免被某APP發(fā)現(xiàn)，此處隱藏掉APP的網(wǎng)站鏈接和目錄

通過不斷的下拉刷新該APP的步數(shù)可以看出，發(fā)生變動(dòng)的有三個(gè)網(wǎng)站鏈接，繼續(xù)尋找與步數(shù)記錄相關(guān)的數(shù)據(jù)包可以發(fā)現(xiàn)，它存在于IHttpServletDataService下
進(jìn)一步查看數(shù)據(jù)包

通過查看數(shù)據(jù)包內(nèi)容發(fā)現(xiàn)，整個(gè)步數(shù)的刷新是通過ReqMessageBody以及commond兩個(gè)字段組成的Form提交完成的

Form表單內(nèi)容分析

展開ReqMessageBody的內(nèi)容（使用json數(shù)據(jù)格式方便進(jìn)行查看）

大致判斷步數(shù)主要由stepNumber字段控制，walkdate為計(jì)步日期，同時(shí)listhour列表中包含了每個(gè)計(jì)步小時(shí)周期內(nèi)的具體步數(shù)，雖然不知道具體的含義，但是已經(jīng)不影響數(shù)據(jù)的修改和上傳了

使用requests模擬POST表單提交

到現(xiàn)在我們就找到了影響數(shù)據(jù)步數(shù)的數(shù)據(jù)字段，下面使用python模擬數(shù)據(jù)交互過程

導(dǎo)入需要的類和庫文件

import requests import urllib import json import datetime import time import random

通過分析可以得出，真正標(biāo)識(shí)一個(gè)用戶或者設(shè)備的是deviceserial，這個(gè)可以通過ReqMessageBody看出，同時(shí)為了真實(shí)偽裝POST報(bào)文信息，對(duì)headers進(jìn)行相應(yīng)設(shè)置

url = '網(wǎng)站鏈接' headers = {'User-Agent' : 'Dalvik/2.1.0 (Linux; U; Android 8.0.0; MHA-TL00 Build/HUAWEIMHA-TL00)','Content-Type' : 'application/x-www-form-urlencoded; charset=UTF-8','Content-Length' : '2000','Connection' : 'keep-alive'} today = (datetime.datetime.now() - datetime.timedelta(days = 0)) yesterday = (datetime.datetime.now() - datetime.timedelta(days = 1)) str_today = today.strftime("%Y%m%d") str_yesterday = yesterday.strftime("%Y%m%d")

表頭中設(shè)置了User-Agent和Content-Type等關(guān)鍵信息，同時(shí)使用datetime函數(shù)以及strftime函數(shù)獲取格式化為20180910格式的當(dāng)前日期
為了模擬步數(shù)的真實(shí)性，使用random.randint函數(shù)獲取每個(gè)小時(shí)時(shí)段內(nèi)的隨機(jī)步數(shù)

hour6_1number = random.randint(500,1500)hour6_2number = random.randint(500,1500)hour7_1number = random.randint(500,1500)hour7_2number = random.randint(500,1500)hour8_1number = random.randint(500,1500)hour8_2number = random.randint(500,1500)hour10_1number = random.randint(500,1500)hour10_2number = random.randint(500,1500)hour12_1number = random.randint(500,1500)hour12_2number = random.randint(500,1500)hour13_1number = random.randint(500,1500)hour13_2number = random.randint(500,1500)hour18_1number = random.randint(500,1500)hour18_2number = random.randint(500,1500)hour19_1number = random.randint(500,1500)hour19_2number = random.randint(500,1500)hour20_1number = random.randint(500,1500)hour20_2number = random.randint(500,1500)hour21_1number = random.randint(500,1500)hour21_2number = random.randint(500,1500)
