我正在尝试从pisa实用程序转换html2pdf。请检查下面的代码。我收到了一些我无法弄清楚的错误。
Traceback (most recent call last):
File "dewa.py", line 27, in <module>
html = html.encode(enc, 'replace')
UnicodeDecodeError: 'ascii' codec can't decode byte 0xd9 in position 203: ordinal not in range(128)
请在此处查看代码。
from cStringIO import StringIO
from grab import Grab
from grab.tools.lxml_tools import drop_node, render_html
from grab.tools.text import remove_bom
from lxml import etree
import grab.error
import inspect
import lxml
import os
import sys
import xhtml2pdf.pisa as pisa
enc = 'utf-8'
filePath = '~/Desktop/dewa'
##############################
g = Grab()
g.go('http://www.dewa.gov.ae/arabic/aboutus/dewahistory.aspx')
html = g.response.body
html = html.replace('bgcolor="EDF389"', 'bgcolor="#EDF389"')
''' clear page '''
html = html.encode(enc, 'replace')
print html
f = file(filePath + '.html' , 'wb')
f.write(html)
f.flush()
f.close()
''' Save PDF '''
pdfresult = StringIO()
pdf = pisa.pisaDocument(StringIO(html), pdfresult, encoding = enc)
f = file(filePath + '.pdf', 'wb')
f.write(pdfresult.getvalue())
f.flush()
f.close()
pdfresult.close()
答案 0 :(得分:2)
如果您检查此行返回的对象类型:
html = g.response.body
你会看到不是是一个unicode对象:
print type(html)
...
<type 'str'>
所以当你走到这一行时:
html = html.encode(enc, 'replace')
您正在尝试重新编码已编码的字符串(导致错误)。
要解决此问题,请将代码更改为:
# decode the dowloaded data
html = g.response.body.decode(enc)
# html is now a unicode object
html = html.replace('bgcolor="EDF389"', 'bgcolor="#EDF389"')
print html
# encode as utf-8 before writing to file (no need for 'replace')
html = html.encode(enc)
