1. Capture APP data packets
For details of the method, please refer to this blog post: http://my.oschina.net/jhao104/blog/605963
Get the address of the Super Curriculum Login : http://120.55.151.61/V2/StudentSkip/loginCheckV4.action
Form:
The form includes the user name and password, which of course are encrypted, and there is also a device information, which is directly posted in the past.
In addition, the header must be added. At first, I got a login error without adding the header, so I have to bring the header information.
2. Login
Login code:
import urllib2
from cookielib import CookieJar
loginUrl = '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
Successful login will return a string of json data of account information
Just like the data returned when capturing packets, it proves that the login is successful.
3. Capture data
Use the same method to get the url and post parameters of the topic
The practice is the same as the simulated login website. For details, see: http://my.oschina.net/jhao104/blog/547311
See the final code below, with home page fetching and pull-down loading updates. Topic content can be loaded infinitely.
