1. Grab APP data package
Please refer to this blog post for detailed methods: http://my.oschina.net/jhao104/blog/605963
Get the login address of the super curriculum: http://120.55.151.61/V2/StudentSkip/loginCheckV4.action
Form:
The form includes the user name and password. Of course, they are all encrypted. There is also a device information. Direct post is used to be.
In addition, header must be added. What I didn't add at the beginning is the login error, so I need 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
After successful login, a string of json data of account information will be returned
It is the same as the data returned during packet capturing to prove the success of login
3. Grab data
Get the url and post parameters of the topic in the same way
It's the same as a simulated Login site. See: http://my.oschina.net/jhao104/blog/547311
See the final code below, there are home page access and drop-down loading updates. Topic content can be loaded infinitely.
