使用urllib2请求URL时,为什么会出现"HTTP错误405:方法不允许"？

Question

我在python中使用urllib2和urllib库

假设我有以下代码

import urllib2
import urllib

url = 'http://ah.example.com'
half_url = u'/servlet/av/jd?ai=782&ji=2624743&sn=I'

req = urllib2.Request(url, half_url.encode('utf-8'))
response = urllib2.urlopen(req)
print response

当我运行上面的代码时,我收到以下错误

Traceback (most recent call last):
  File "example.py", line 39, in <module>
    response = urllib2.urlopen(req)
  File "/usr/lib64/python2.7/urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib64/python2.7/urllib2.py", line 398, in open
    response = meth(req, response)
  File "/usr/lib64/python2.7/urllib2.py", line 511, in http_response
    'http', request, response, code, msg, hdrs)
  File "/usr/lib64/python2.7/urllib2.py", line 436, in error
    return self._call_chain(*args)
  File "/usr/lib64/python2.7/urllib2.py", line 370, in _call_chain
    result = func(*args)
  File "/usr/lib64/python2.7/urllib2.py", line 519, in http_error_default
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib2.HTTPError: HTTP Error 405: Method Not Allowed

任何人都可以让我知道这里发生了什么,为什么它不起作用

您正在呼叫的服务器告诉您,您尝试呼叫的URL不允许使用POST方法.

通过传入URL的路径部分作为Request对象数据参数,您将使其成为POST而不是GET.

我怀疑你想发送一个GET请求:

req = urllib2.Request(url + half_url.encode('utf-8'))
