QtWebKit解析js页面

WekKit官网：http://www.webkit.org/

QtWebKit官网及安装：http://trac.webkit.org/wiki/QtWebKit#GettingInvolved



QtWebKit Class Reference:http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qtwebkit.html

QtWebKit也可以在PyQt4的安装中顺带安装（/article/9720264.html 46条）

1.用python的urllib库从服务端读取web页面（html+js）

#encoding=utf-8

import urllib, urlparse

if __name__ == '__main__':
baseUrl = 'http://s.weibo.com/weibo/'
wordList = ['python','c++','钓鱼岛', '博圣云峰', '加勒比海盗', '海贼王', '2012', '世界末日', '地球']
for index in range(len(wordList)):
url = urlparse.urljoin(baseUrl, urllib.quote(urllib.quote(wordList[index])))
print url
conn = urllib.urlopen(url)
data = conn.read()
f = file('/tmp/%s' % (wordList[index]), 'w')
f.write(data)
f.close()

2.用QtWebKit解析web页面（html+js）

#!/usr/bin/env python
#encoding=utf-8

import sys
from PyQt4.QtGui import *
from PyQt4.QtCore import *
from PyQt4.QtWebKit import *
import time

class Render(QWebPage):
def __init__(self):
self.wordList = ['python','c++','钓鱼岛', '博圣云峰', '加勒比海盗', '海贼王', '2012', '世界末日', '地球']
self.index = 0
self.app = QApplication(sys.argv)
QWebPage.__init__(self)
self.loadFinished.connect(self._loadFinished)
self.mainFrame().setHtml(file('/tmp/%s'%self.wordList[self.index], 'r').read())
self.app.exec_()

def _loadFinished(self, result):
file('/home/dongsong/桌面/%s.html'%self.wordList[self.index],'w').write(unicode(self.mainFrame().toHtml()).encode('utf-8'))
self.index += 1
if self.index >= len(self.wordList):
self.app.quit()
else:
self.mainFrame().setHtml(file('/tmp/%s'%self.wordList[self.index], 'r').read())

page = Render()

PS:可以用self.mainFrame().load(QUrl('http://s.weibo.com/python')直接访问页面并解析（html+js），上述示例只是为了演示如何解析已经读取到的pageData
