想使用python爬取京东的快递信息，现在需要解决的首要问题是使用python模拟浏览器登陆，遇到了下面的问题。

_t _ntNBMNX ({"username":"\u8bf7\u60a8\u518d\u6b21\u767b\u5f55","_t":"_ntaLJJS"})

所有代码如下。

import urllib import urllib2 import cookielib import re import socket from bs4 import BeautifulSoup def Navigate(url, data={}): tryTimes = 0 while True: if (tryTimes > 20): print 'try many time ..' break try: if (data == {}): req = urllib2.Request(url) else: req = urllib2.Request(url, urllib.urlencode(data)) req = urllib2.urlopen(req).read() tryTimes = tryTimes + 1 except socket.error: print 'connection failure' else: break return req def func(): try: cookie = cookielib.CookieJar() cookieProc = urllib2.HTTPCookieProcessor(cookie) except: raise else: opener = urllib2.build_opener(cookieProc) opener.addheaders = [('User-Agent', 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11')] urllib2.install_opener(opener) url = "https://passport.jd.com/uc/login" login = Navigate(url) loginSoup = BeautifulSoup(login,"html.parser") # looking for uuid uuid = loginSoup.find_all("form")[0].find_all("input")[0]['value'] #print uuid clrName=loginSoup.find_all("form")[0].find_all("input")[6]['name'] clrValue=loginSoup.find_all("form")[0].find_all("input")[6]['value'] # look rand prama.. ###clr = loginSoup.find_all("span", "clr")[0] ###clrName = clr.find_next_siblings("input")[0]['name'] ###clrValue = clr.find_next_siblings("input")[0]['value'] print clrName,clrValue ### url = "http://passport.jd.com/uc/loginService" myurl = 'http://127.0.0.1:5000' #loginurl = 'https://passport.jd.com/new/misc/js/login2016.js' # print url postData = { 'loginname': 'my-username', 'nloginpwd': 'my-password', 'loginpwd': 'my-password', ## 'machineNet':'', ## 'machineCpu':'', ## 'machineDisk':'', str(clrName):str(clrValue), 'uuid': uuid, 'authcode': '' } passport = Navigate(url, postData) print passport
