python – UnicodeDecodeError：’utf8’编解码器无法解码位置34的字节0xc3：意外的数据结束

我的代码看起来像这样：

from urllib import FancyURLopener
import os

class MyOpener(FancyURLopener): #spoofs a real browser on Window
   version = 'Mozilla/5.0 (Windows; U; Windows NT 5.1; it; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11'

print "What is the webaddress?"
webaddress = raw_input("8::>")

print "Folder Name?"
foldername = raw_input("8::>")

if not os.path.exists(foldername):
    os.makedirs(foldername)

def urlpuller(start,page):
   while page[start]!= '"':
      start += 1
   close = start
   while page[close]!='"':
      close += 1
   return page[start:close]

myopener = MyOpener()

response = myopener.open(webaddress)
site = response.read()

nexturl = ''
counter = 0

while(nexturl!=webaddress):
   counter += 1
   start = 0

   for i in range(len(site)-35):
       if site[i:i+35].decode('utf-8') == u'<img id="imgSized" class="slideImg"':
         start = i + 40
         break
   else:
      print "Something's broken,chief. Error = 1"

   next = 0

   for i in range(start,8,-1):
      if site[i:i+8] == u'<a href=':
         next = i
         break
   else:
      print "Something's broken,chief. Error = 2"

   nexturl = urlpuller(next,site)

   myopener.retrieve(urlpuller(start,site),foldername+'/'+foldername+str(counter)+'.jpg')

print("Retrieval of "+foldername+" completed.")

当我尝试使用我正在使用的网站运行它时,它会返回错误：

Traceback (most recent call last):
  File "yada/yadayada/Python/scraper.py",line 37,in <module>
    if site[i:i+35].decode('utf-8') == u'<img id="imgSized" class="slideImg"':
  File "/usr/lib/python2.7/encodings/utf_8.py",line 16,in decode
    return codecs.utf_8_decode(input,errors,True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xc3 in position 34: unexpected end of data

当指向http://google.com时,它工作得很好.

<Meta http-equiv="Content-Type" content="text/html; charset=utf-8">

但是当我尝试使用utf-8进行解码时,正如您所看到的,它不起作用.

有什么建议？
