python：打印有关BadStatusLine错误的信息

执行以下python脚本后，我收到BadStatusLine。我如何打印有关BadStatusLine的详细信息？python：打印有关BadStatusLine错误的信息

#!/usr/bin/python 

import urllib 
import urllib2 
import httplib 


try: 
    # NoActiveDevsPerQtr 
    request = urllib2.Request('http://127.0.0.1:8090') 

    request.add_header('Accept',  'text/csv') 
    request.add_header('User-Agent', 'python-script') 

    request.add_data(""" 
     <? xml version="1.0"?> 
     <log_query> 
      <querytype>ListPerQtr</querytype> 
      <year>2014</year> 
      <quarter>3</quarter> 
     </log_query> 
    """) 


    response = urllib2.urlopen(request) 
    content = response.read() 
    print content 

except httplib.BadStatusLine as e: 
    print e

打印e不打印任何东西。

您能否显示正在抛出的实际错误？ – 2014-10-30 15:10:18

可能[dupe]（http://stackoverflow.com/questions/1767934/why-am-i-getting-this-error-in-python-httplib）？ – Noelkd 2014-10-30 15:34:32

源（“httplib.py”）表示，这在它提出“BadStatusLine一种情况：

按照要求，当我删除除了httplib.BadStatusLine是如下被抛出的实际错误'：

 if not line: 
     # Presumably, the server closed the connection before 
     # sending a valid response. 
     raise BadStatusLine(line)

也许你正在碰到这种情况，暗示该行为空或空。

这看起来像一个疲惫的程序员决定;定义另一个例外情况会更好，比如'NoStatusLine'
