我正在尝试编写一些代码来抓取网页。我正在使用 spynner 获取 html 代码并将其传递给比萨

运行 python 代码时我没有看到任何错误，但是生成的 pdf 都是错误的。

这是我使用的代码 -

import os
import sys
import ho.pisa as pisa
import spynner

import logging
class PisaNullHandler(logging.Handler):
    def emit(self, record):
        pass


url = 'http://www.google.com'

br = spynner.Browser()

br.load(url)

pathToWrite = './google.html.pdf'

htmlCode = br.html

pdfFile = file(pathToWrite, "wb+")
try:
    logging.getLogger("ho.pisa").addHandler(PisaNullHandler())
    pdfStatus = pisa.CreatePDF(htmlCode.encode("utf-8"), pdfFile, encoding="utf8" )
    if not pdfStatus.err:
        pdfFile.flush()
    else:
        print 'Failed with error ' + pdfStatus.error
except Exception as e:
    print 'pdf creation failed with error ' + str(e)

我试图从 spynner 保存 html 并通过 xhtml2pdf 运行它。我收到以下错误 -
