我想从 http://tisv.freeway.gov.tw/ 下载高速公路车流的资料 下载资料的连结是 http://tisv.freeway.gov.tw/roadlevel_info.xml.gz 使用python 3.4，程式码如下 import urllib.request url = 'http://tisv.freeway.gov.tw/roadlevel_info.xml.gz' username = xxxxxxx password = xxxxxxx auth_handler = urllib.request.HTTPBasicAuthHandler() auth_handler.add_password(None, url, username, password) opener = urllib.request.build_opener(auth_handler) urllib.request.install_opener(opener) result = opener.open(url) 程式码是从 https://docs.python.org/3/library/urllib.request.html#examples 里的Use of Basic HTTP Authentication复制下来 只有在最後一行我把urlopen改成opener.open 但是跑了之後依然出现 HTTP Error 401 以下是error Traceback (most recent call last): File "<stdin>", line 26, in <module> File "/usr/lib/python3.4/urllib/request.py", line 461, in open response = meth(req, response) File "/usr/lib/python3.4/urllib/request.py", line 571, in http_response 'http', request, response, code, msg, hdrs) File "/usr/lib/python3.4/urllib/request.py", line 499, in error return self._call_chain(*args) File "/usr/lib/python3.4/urllib/request.py", line 433, in _call_chain result = func(*args) File "/usr/lib/python3.4/urllib/request.py", line 579, in http_error_default raise HTTPError(req.full_url, code, msg, hdrs, fp) urllib.error.HTTPError: HTTP Error 401: Authorization Required 关於HTTP认证的部份，我完全没有概念，所以我想请问要怎麽解决这个问题？ 还有相关的知识要去哪里才能找到，我完全不知从何下手 帐号、密码我确定是对的，从浏览器上都可以下载 先谢谢大家了。 --
