Question

我有一个奇怪的问题。我有一些pyqt-4代码设置来绘制和捕获指定网址的图像。这是代码：

def save_page(webpage, output):
    global error
    global AWSError
    # Set the size of the (virtual) browser window
    webpage.setViewportSize(webpage.mainFrame().contentsSize())
    # Paint this frame into an image
    image = QImage(webpage.viewportSize(), QImage.Format_ARGB32)
    painter = QPainter(image)
    webpage.mainFrame().render(painter)
    painter.setOpacity(opacity)
    painter.setPen(QtCore.Qt.blue)
    painter.setFont(QtGui.QFont('arial', 15))
    painter.drawText(image.rect(), QtCore.Qt.AlignVertical_Mask | QtCore.Qt.AlignRight , WaterMarktxt + ' ' + str(now.strftime(" %d. %B %Y %I:%M%p")))
    painter.end()

    image.save(ImageDestinationPath + "/" + output + ".png")

现在我为applciation指定了多个url并且它们处理得非常好但是当我处理http://www.google.com（它重定向到https）时出现错误。这是堆栈。请注意图片ID = 0000..1适用于Google，图片ID = 0000 ..适用于所有其他网址。

正如您所看到的，它无法为谷歌形成图像，而对于几乎所有其他网址都成功。任何具体原因？它与我指定的图像容量或图像大小有关吗？
