再次 urllib.error.HTTPError: HTTP Error 400: Bad Request [英] Again urllib.error.HTTPError: HTTP Error 400: Bad Request

问题描述

嗨！我试图打开通常在浏览器中打开的网页，但python只是发誓不想工作.

Hy! I tried to open web-page, that is normally opening in browser, but python just swears and does not want to work.

import urllib.request, urllib.error
f = urllib.request.urlopen('http://www.booking.com/reviewlist.html?cc1=tr;pagename=sapphire')

另一种方式

import urllib.request, urllib.error
opener=urllib.request.build_opener()
f=opener.open('http://www.booking.com/reviewlist.html?cc1=tr;pagename=sapphi
re')

两个选项都给出了一种错误:

Both options give one type of error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python34\lib\urllib\request.py", line 461, in open
    response = meth(req, response)

urllib.error.HTTPError: HTTP Error 400: Bad Request

有什么想法吗?

推荐答案

此 URL 似乎在执行用户代理字符串检查.如果我将 Firefox 中的用户代理字符串调整为 Python-urllib/2.7，它会因您看到的 Bad Request 而失败.

This URL seems to be doing user agent string checking. If I adjust my user agent string in Firefox to Python-urllib/2.7, it fails with the Bad Request you are seeing.

当您使用 urllib 时，您可以按照此教程

As you are using urllib, you can adjust the User Agent following this tutorial

from urllib.request import FancyURLopener

class MyOpener(FancyURLopener):
    version = 'My new User-Agent'   # Set this to a string you want for your user agent

myopener = MyOpener()
page = myopener.open('http://www.booking.com/reviewlist.html?cc1=tr;pagename=sapphire')
