500 error with urllib.request.urlopen

问题:

The following code:

   req = urllib.request.Request(url=r"http://borel.slu.edu/cgi-bin/cc.cgi?foirm_ionchur=im&foirm=Seol&hits=1&format=xml",headers={'User-Agent':' Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0'})    handler = urllib.request.urlopen(req) 

is giving me the following exception:

Traceback (most recent call last):   File "C:/Users/Foo/lang/old/test.py", line 46, in <module>     rip()   File "C:/Users/Foo/lang/old/test.py", line 36, in rip     handler = urllib.request.urlopen(req)   File "C:\Python32\lib\urllib\request.py", line 138, in urlopen     return opener.open(url, data, timeout)   File "C:\Python32\lib\urllib\request.py", line 375, in open     response = meth(req, response)   File "C:\Python32\lib\urllib\request.py", line 487, in http_response     'http', request, response, code, msg, hdrs)   File "C:\Python32\lib\urllib\request.py", line 413, in error     return self._call_chain(*args)   File "C:\Python32\lib\urllib\request.py", line 347, in _call_chain     result = func(*args)   File "C:\Python32\lib\urllib\request.py", line 495, in http_error_default     raise HTTPError(req.full_url, code, msg, hdrs, fp) urllib.error.HTTPError: HTTP Error 500: Internal Server Error 

but it works fine in my browser, whats the issue?

The server is rather b0rken. It responds with a 500 error in the browser as well.

You can catch the exception and still read the response:

import urllib.request from urllib.error import HTTPError  req = urllib.request.Request(url=r"http://borel.slu.edu/cgi-bin/cc.cgi?foirm_ionchur=im&foirm=Seol&hits=1&format=xml",headers={'User-Agent':' Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0'}) try:     handler = urllib.request.urlopen(req) except HTTPError as e:     content = e.read()
