python – 打印来自QNetworkCookie,PyQt4的cookie

导读：我正在尝试存储我从网站获得的所有cookie而不是打印它们. 请帮助我让它工作,因为我认为我不存储任何东西,这就是我没有输出任何东西的原因. 我正在谷歌网站上测试这个代码,我很确定他们一旦到达那里就会存储cookie. 所以我正在尝试获取所有可用的cookie并打印

我正在尝试存储我从网站获得的所有cookie而不是打印它们.
请帮助我让它工作,因为我认为我不存储任何东西,这就是我没有输出任何东西的原因. 我正在谷歌网站上测试这个代码,我很确定他们一旦到达那里就会存储cookie. 所以我正在尝试获取所有可用的cookie并打印它们.这是代码： #! /usr/bin/env python2.7
from PyQt4.QtCore import *
from PyQt4.QtGui import *
from PyQt4.QtNetwork import *
from PyQt4.QtWebKit import *
import sys,os,simplejson,signal
class MainWindow(QMainWindow):
def __init__(self):
QMainWindow.__init__(self)
self.tabs = QTabWidget()
self.setCentralWidget(self.tabs)
self.settings = QSettings()
self.numberOfTabs = 0
self.cookies = QNetworkCookieJar()
self.cookies.setAllCookies([QNetworkCookie.parseCookies(c)[0] for c in self.get('cookiejar')])
def put(self,key,value):
self.settings.setValue(key,simplejson.dumps(value))
self.settings.sync()
def get(self,key):
v = self.settings.value(key)
return simplejson.loads(unicode(v.toString()))
def addNewTab(self,url=QUrl('')):
self.numberOfTabs += 1
self.tabs.setCurrentIndex(self.tabs.addTab(Tab(QUrl(url)),'%s'%str(self.numberOfTabs)))
self.setCookies()
return self.tabs.currentWidget()
def setCookies(self):
self.put('cookiejar',[str(c.toRawForm()) for c in self.cookies.allCookies()])
print self.get('cookiejar')
class Tab(QWebView):
def __init__(self,url):
QWebView.__init__(self)
self.load(url)
if __name__ == '__main__':
app = QApplication(sys.argv)
browser = MainWindow()
browser.addNewTab('https://google.com')
browser.show()
if signal.signal(signal.SIGINT,signal.SIG_DFL):
sys.exit(app.exec_())
app.exec_()
解决方法
你应该在检查cookie之前等待loadFinished,无论如何,也许这样的东西适合你,在这里我重新实现QNetworkCookieJar并完成从那里存储和加载cookie的所有工作：
