HTTP错误409:冲突urllib2 python

Question

我想迭代不同的url api请求列表?get变量(x1，....，xn)。

from urllib2 import urlopen, Request
import pandas as pd
var=[x[0],...,x[n]]
url_list=['http://BLAH/get?var[0]&fmt=csv','http://BLAH/get?var[1]&fmt=csv',...      ...,'http://BLAH/get?var[n]&fmt=csv']
j=0
while j < len(url_list):
    req=Request(url_list[j])
    response=urlopen(req)
    df=pd.read_csv(response)
    print df
    j=j+1**

我已经尝试删除request和response.close()，但我的代码仍然产生冲突错误。

 File "C:UsersAnacondaliburllib2.py", line 127, in urlopen
  return _opener.open(url, data, timeout)
 File "C:UsersAnacondaliburllib2.py", line 410, in open
  response = meth(req, response)
 File "C:UsersAnacondaliburllib2.py", line 523, in http_response
  'http', request, response, code, msg, hdrs)
 File "C:UsersnfitzsimonsAnacondaliburllib2.py", line 448, in error
   return self._call_chain(*args)
 File "C:UsersAnacondaliburllib2.py", line 382, in _call_chain
   result = func(*args)
 File "C:UsersAnacondaliburllib2.py", line 531, in http_error_default
   raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
    rllib2.HTTPError: HTTP Error 409: Conflict

有人有什么建议吗?

如果您只是尝试遍历url列表并在成功请求时打印内容，为什么不尝试一下呢?

#!/usr/bin/env python
try:
    import requests
except ImportError as err:
    print("Woops, you're missing " + str(err))

urls = []
req = requests
for url in urls:
   response =  req.get(url)
   if response.status_code == 200: #Successful request
       print(response.content)
