大多數APP里面返回的是json格式數據,或者一堆加密過的數據 。這里以超級課程表APP為例,抓取超級課程表里用戶發的話題。
1、抓取APP數據包
表單:
表單中包括了用戶名和密碼,當然都是加密過了的,還有一個設備信息,直接post過去就是。
另外必須加header,一開始我沒有加header得到的是登錄錯誤,所以要帶上header信息。
2、登錄
登錄代碼:
import urllib2from cookielib import CookieJarloginUrl = ‘http://120.55.151.61/V2/StudentSkip/loginCheckV4.action’headers = {‘Content-Type’: ‘application/x-www-form-urlencoded; charset=UTF-8’,
‘User-Agent’: ‘Dalvik/1.6.0 (Linux; U; Android 4.1.1; M040 Build/JRO03H)’,‘Host’: ‘120.55.151.61’,‘Connection’: ‘Keep-Alive’,‘Accept-Encoding’: ‘gzip’,‘Content-Length’: ‘207’,}loginData =
‘phoneBrand=Meizu&platform=1&deviceCode=868033014919494&account=FCF030E1F2F6341C1C93BE5BBC422A3D&phoneVersion=16&password=A55B48BB75C79200379D82A18C5F47D6&channel=MXMarket&phoneModel=M040&versionNumber=7.2.1&’cookieJar = CookieJar()opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookieJar))req = urllib2.Request(loginUrl, loginData, headers)loginResult = opener.open(req).read()print loginResult
登錄成功 會返回一串賬號信息的json數據
和抓包時返回數據一樣,證明登錄成功
3、抓取數據
用同樣方法得到話題的url和post參數
下見最終代碼,有主頁獲取和下拉加載更新??梢詿o限加載話題內容。
