解決Python3 抓取微信賬單信息問題

更新時間：2019年07月19日 10:07:06 作者：alan_山

這篇文章主要介紹了Python3 抓取微信賬單信息,本文通過實例代碼給大家介紹的非常詳細(xì)，具有一定的參考借鑒價值，需要的朋友可以參考下

這段時間有個朋友想導(dǎo)出微信里面的賬單信息，后來發(fā)現(xiàn)微信的反爬蟲還是很厲害的，花了點時間去分析。

一、采用傳統(tǒng)模擬http抓取

抓取的主要URL:https://wx.tenpay.com/userroll/userrolllist，其中后面帶上三個參數(shù)，具體參數(shù)見代碼,其中exportkey這參數(shù)是會過期的，userroll_encryption和userroll_pass_ticket 這兩個參數(shù)需要從cookie中獲得，應(yīng)該是作為獲取數(shù)據(jù)的標(biāo)識，通過抓包也看不出端倪，應(yīng)該是微信程序內(nèi)部生成的，如果使用微信開發(fā)著工具登錄后直接訪問網(wǎng)址有的時候可以訪問返回數(shù)據(jù)，但是只是在較短的時間內(nèi)有效，而且當(dāng)返回會話超時后，繼續(xù)使用網(wǎng)頁訪問就會被限制，一直提示會話超時，應(yīng)該是在網(wǎng)頁和移動端中exportkey有不同的時間和訪問次數(shù)的限制。

之后想通過破解seesion的方式，研究了一下，發(fā)現(xiàn)這是不可能的，想要破解session需要搞定wx.login，而wx.login是微信提供的，想要破解難度應(yīng)該不用我說了。

二、解決exportkey 這個key和Cookie的獲取

需要的工具：

1、安卓/蘋果手機

2、Fiddler（抓包工具）

搞過爬蟲的都知道Fiddler，具體操作就不多說了，設(shè)置好代理和開啟Fiddler后，抓取url中的exportkey和相應(yīng)的Cookie，用于接下來的數(shù)據(jù)抓取。

三、上代碼

代碼寫的不是很好，若有錯誤還望各位大大指正。

因為是幫朋友抓取的，能實現(xiàn)就可以了。之后若有需要再繼續(xù)優(yōu)化代碼吧！
