Gnip问题-创建作业时- urllib2.URLError

Question

我正在尝试使用Gnip Historical API创建作业。

我对urllib有意见..

import urllib2  
import base64  
import json  
UN = '' # YOUR GNIP ACCOUNT EMAIL ID  
PWD = ''  
account = '' # YOUR GNIP ACCOUNT USER NAME  
def get_json(data):  
    return json.loads(data.strip())  
def post():  
    url = 'https://historical.gnip.com/accounts/' + account + '/jobs.json'  
    publisher = "twitter"  
    streamType = "track"  
    dataFormat = "activity-streams"  
    fromDate = "201510140630"  
    toDate = "201510140631"  
    jobTitle = "job30"  
    rules = '[{"value":"","tag":""}]'  
    jobString = '{"publisher":"' + publisher + '","streamType":"' + streamType + '","dataFormat":"' + dataFormat + '","fromDate":"' + fromDate + '","toDate":"' + toDate + '","title":"' + jobTitle + '","rules":' + rules + '}'  
    base64string = base64.encodestring('%s:%s' % (UN, PWD)).replace('\n', '')  
    req = urllib2.Request(url=url, data=jobString)  
    req.add_header('Content-type', 'application/json')  
    req.add_header("Authorization", "Basic %s" % base64string)  

    proxy = urllib2.ProxyHandler({'http': 'http://proxy:8080', 'https': 'https://proxy:8080'})  
    opener = urllib2.build_opener(proxy)  
    urllib2.install_opener(opener)  
    try:  
        response = urllib2.urlopen(req)  
        the_page = response.read()  
        the_page = get_json(the_page)  
        print 'Job has been created.'  
        print 'Job UUID : ' + the_page['jobURL'].split("/")[-1].split(".")[0]  
    except urllib2.HTTPError as e:  
        print e.read()  

if __name__=='__main__':  
    post()  

这是我得到的错误：

Traceback (most recent call last):
  File "gnip1.py", line 37, in <module>
    post()  
  File "gnip1.py", line 28, in post
    response = urllib2.urlopen(req)  
  File "/home/soundarya/anaconda-new-1/lib/python2.7/urllib2.py", line 154, in urlopen
    return opener.open(url, data, timeout)
  File "/home/soundarya/anaconda-new-1/lib/python2.7/urllib2.py", line 431, in open
    response = self._open(req, data)
  File "/home/soundarya/anaconda-new-1/lib/python2.7/urllib2.py", line 449, in _open
    '_open', req)
  File "/home/soundarya/anaconda-new-1/lib/python2.7/urllib2.py", line 409, in _call_chain
    result = func(*args)
  File "/home/soundarya/anaconda-new-1/lib/python2.7/urllib2.py", line 1240, in https_open
    context=self._context)
  File "/home/soundarya/anaconda-new-1/lib/python2.7/urllib2.py", line 1197, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error [Errno -2] Name or service not known>

我甚至尝试过curl命令：

当我尝试在终端中运行下面的程序时，我得到了错误- ServiceUsername无效。

curl -v -X -uname -d '{"title"："HPT_test_job"，"publisher"："Twitter"，"streamType":"track"，"dataFormat":"activity-streams"，"fromDate":"201401010000"，"toDate":"201401020000 "，"rules":{"value"："twitter_lang:en (希拉里·克林顿或唐纳德)“，"tag"："2014_01_01_snow"}}‘'https://historical.gnip.com/accounts/account_name/jobs.json’

这是确切的输出msg：

检索作业状态时出错：{u‘’serviceUsername‘：u’‘is invalid'} --请验证连接参数和网络连接*

试试这个..。看看有没有帮助

import urllib2
from urllib2.request import urlopen 
u = urlopen ('http:// .........')

Answer 2

如果你使用的是Python3.5，你应该使用库urllib.request，它是urllib2的更新版本。但是，请注意，这会更改代码中的一些内容，包括print (应该放在括号中)和需要将一些字符串结果转换为字节。Here您可以查看适用于Python3.5的所有必需的代码更改
