python - 使用 python 点击​​ http url 获取 IOError

Question

我尝试按如下方式进行操作

import urllib
second_query="http://example.com"
pw = urllib.urlopen(second_query)
pw = pw.read()
print pw

我正在尝试点击 jira api - http://example.com但我收到以下错误

Traceback (most recent call last):
      File "abc.py", line 7, in <module>
        pw = urllib.urlopen(second_query)
      File "/abc/xyz/pqr/thirdparty/python/2.6/lib/python2.6/urllib.py", line 87, in urlopen
        return opener.open(url)
      File "/abc/xyz/pqr/thirdparty/python/2.6/lib/python2.6/urllib.py", line 203, in open
        return getattr(self, name)(url)
      File "/abc/xyz/pqr/thirdparty/python/2.6/lib/python2.6/urllib.py", line 358, in open_http
        return self.http_error(url, fp, errcode, errmsg, headers)
      File "/abc/xyz/pqr/thirdparty/python/2.6/lib/python2.6/urllib.py", line 371, in http_error
        result = method(url, fp, errcode, errmsg, headers)
      File "/abc/xyz/pqr/thirdparty/python/2.6/lib/python2.6/urllib.py", line 683, in http_error_401
        errcode, errmsg, headers)
      File "/abc/xyz/pqr/thirdparty/python/2.6/lib/python2.6/urllib.py", line 381, in http_error_default
        raise IOError, ('http error', errcode, errmsg, headers)
    IOError: ('http error', 401, 'Unauthorized', <httplib.HTTPMessage instance at 0x138e26c8>)

请提出解决方案。

Answer 1

通过阅读错误，可以清楚地看出您没有所需的授权:

IOError: ('http error', 401, 'Unauthorized', <httplib.HTTPMessage instance at 0x138e26c8>

您必须以某种方式提供必要的凭据...但是我很确定 Jira 提供了高级 API 来使用其工具，因此您不必使用低级方法。
