print htmlContent

另外要用到的两个类是WeiboSearch.py和WeiboEncode.py。
WeiboEncode.py代码如下：

#coding=utf-8
import urllib
import base64
import rsa
import binascii
def PostEncode(userName, passWord, serverTime, nonce, pubkey, rsakv):
"Used to generate POST data"
encodedUserName = GetUserName(userName)#用户名使用base64加密
encodedPassWord = get_pwd(passWord, serverTime, nonce, pubkey)#目前密码采用rsa加密
postPara = {
'entry': 'weibo',
'gateway': '1',
'from': '',
'savestate': '7',
'userticket': '1',
'ssosimplelogin': '1',
'vsnf': '1',
'vsnval': '',
'su': encodedUserName,
'service': 'miniblog',
'servertime': serverTime,
'nonce': nonce,
'pwencode': 'rsa2',
'sp': encodedPassWord,
'encoding': 'UTF-8',
'prelt': '115',
'rsakv': rsakv,
'url': 'http://weibo.com/ajaxlogin.php?framelogin=1&callback=parent.sinaSSOController.feedBackUrlCallBack',
'returntype': 'META'
}
postData = urllib.urlencode(postPara)#网络编码
return postData

def GetUserName(userName):
"Used to encode user name"
userNameTemp = urllib.quote(userName)
userNameEncoded = base64.encodestring(userNameTemp)[:-1]
return userNameEncoded

def get_pwd(password, servertime, nonce, pubkey):
rsaPublickey = int(pubkey, 16)
key = rsa.PublicKey(rsaPublickey, 65537) #创建公钥
message = str(servertime) + '\t' + str(nonce) + '\n' + str(password) #拼接明文js加密文件中得到
passwd = rsa.encrypt(message, key) #加密
passwd = binascii.b2a_hex(passwd) #将加密信息转换为16进制。
return passwd

WeiboSearch.py

#coding=utf-8
import re
import json
def sServerData(serverData):#解析得到serverTime，nonce等
"Search the server time & nonce from server data"
p = re.compile('\((.*)\)') #re.compile 可以把正则表达式编译成一个正则表达式对象
jsonData = p.search(serverData).group(1) #查找
data = json.loads(jsonData) #对encodedjson进行decode，得到原始数据，需要使用json.loads()函数
serverTime = str(data['servertime'])
nonce = data['nonce']
pubkey = data['pubkey']#
rsakv = data['rsakv']#
print "Server time is:", serverTime
print "Nonce is:", nonce
return serverTime, nonce, pubkey, rsakv

def sRedirectData(text):
p = re.compile('location\.replace\([\'"](.*?)[\'"]\)')
loginUrl = p.search(text).group(1)
print 'loginUrl:',loginUrl
return loginUrl

目前该爬虫可以自动登录，以及调用新浪微博的普通API。但是批量取回他人的微博需要高级授权，目前正在申请。
