The server is rather b0rken. It responds with a 500 error in the browseras well.
服务器相当b0rken。它也在浏览器中响应 500 错误。
You can catch the exception and still read the response:
您可以捕获异常并仍然读取响应：
import urllib.request
from urllib.error import HTTPError
req = urllib.request.Request(url=r"http://borel.slu.edu/cgi-bin/cc.cgi?ftheitroadm_ionchur=im&ftheitroadm=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()
