python3.5 urllib.request.urlopen报错

问题描述

问 题

小白想自学python爬取网页信息，但是代码写了第二行就老是报错，度娘了很久感觉不是很能get,求大神点拨！

import urllib.request

Target = "http://www.tmsf.com/newhouse/property_330181_287055905_price.htm"
url = urllib.request.urlopen(Target)-----报错行
page = url.read()
url.close()
fp = open("grab.txt","wb")
fp.write(page)
fp.close()

报错信息
Traceback (most recent call last):

url = urllib.request.urlopen(Target)

return opener.open(url, data, timeout)

return self._call_chain(*args)

result = func(*args)

File "C:UsersjqhAppDataLocalProgramsPythonPython35liburllibrequest.py", line 589, in http_error_default

raise HTTPError(req.full_url, code, msg, hdrs, fp)

urllib.error.HTTPError: HTTP Error 403: Forbidden

解决方案

http 403 是对方网站返回的信息，你的代码没问题。

我用你的代码在python3.6.1下作了测试，可以正常运行，页面内容保存在grab.txt中。
