只有https页面的Python抓取javascript网页才会失败

sey*_*ood 12 python ssl https pyqt pyqt5

我正在使用PyQt5来抓取网页,这对于http:// URL非常有用,但对于https:// URL则完全没有.

我脚本的相关部分如下:

class WebPage(QWebPage):
    def __init__(self):
        super(WebPage, self).__init__()

        self.timerScreen = QTimer()
        self.timerScreen.setInterval(2000)
        self.timerScreen.setSingleShot(True)
        self.timerScreen.timeout.connect(self.handleLoadFinished)

        self.loadFinished.connect(self.timerScreen.start)


    def start(self, urls):
        self._urls = iter(urls)
        self.fetchNext()

    def fetchNext(self):
        try:
            url = next(self._urls)
        except StopIteration:
            return False
        else:
            self.mainFrame().load(QUrl(url))
        return True

    def processCurrentPage(self):
        url = self.mainFrame().url().toString()
        html = self.mainFrame().toHtml()

        #Do stuff with html
        print('loaded: [%d bytes] %s' % (self.bytesReceived(), url))

    def handleLoadFinished(self):
        self.processCurrentPage()
        if not self.fetchNext():
            qApp.quit()

对于安全页面,脚本返回空白页面.回来的唯一html就是<html><head></head><body></body></html>.

我有点失落.我是否缺少与处理安全URL相关的设置?

使用PyQt4进行测试并使用HTTPS正常打开页面

import sys
from PyQt4.QtGui import QApplication
from PyQt4.QtCore import QUrl
from PyQt4.QtWebKit import QWebView

class Browser(QWebView):
    def __init__(self):
        QWebView.__init__(self)
        self.loadFinished.connect(self._result_available)

    def _result_available(self, ok):
        frame = self.page().mainFrame()
        print(frame.toHtml())

if __name__ == '__main__':
    app = QApplication(sys.argv)
    view = Browser()
    view.load(QUrl('https://www.google.com'))
    app.exec_()
