以網站的截圖與蟒蛇導致空白頁

所以我想用python腳本把一個網站的截圖：以網站的截圖與蟒蛇導致空白頁

#! /usr/bin/python 

import sys 
import time 
from PyQt4.QtCore import *

from PyQt4.QtWebKit import * 

class Screenshot(QWebView): 
    def __init__(self): 
     self.app = QApplication(sys.argv) 
     QWebView.__init__(self) 
     self._loaded = False 
     self.loadFinished.connect(self._loadFinished) 

    def capture(self, url, output_file): 
     self.load(QUrl(url)) 
     self.wait_load() 
     time.sleep(120) 
     # set to webpage size 
     frame = self.page().mainFrame() 
     self.page().setViewportSize(frame.contentsSize()) 
     # render image 
     image = QImage(self.page().viewportSize(), QImage.Format_ARGB32) 
     painter = QPainter(image) 
     frame.render(painter) 
     painter.end() 
#  print 'saving', output_file 
     image.save(output_file) 

    def wait_load(self, delay=0): 
     # process app events until page loaded 
     while not self._loaded: 
      self.app.processEvents() 
      time.sleep(delay) 
     self._loaded = False 

    def _loadFinished(self, result): 
     self._loaded = True 

    s = Screenshot() 
    s.capture('http://csgo-stats.com/maschs/', 'csgo-stats.png')

它幾乎每一頁上工作，但在現場CSGO-統計.com/maschs（這是我的個人資料頁面），它只是一個空白頁面，沒有頁面上的信息。當我在瀏覽器中打開該頁面時，需要幾秒鐘才能加載，並且可以正確顯示所有內容。結果是這樣的： csgo-stats
