Python HTTP错误505：不支持HTTP版本

sql

我有以下代码：

import re
from re import sub

import cookielib
from cookielib import CookieJar
import urllib2
from urllib2 import urlopen

cj = CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
opener.addheaders=[('user-agent' , 'Safari/7.0.2')]

def check(word):
    try:
        query = "select * from geo.places where text ='"+word+"'"
        sourceCode=opener.open('http://query.yahooapis.com/v1/public/yql?q='+query+'&diagnostics=true').read()
        print sourceCode
    except Exception, e:
        print str(e)
        print 'ERROR IN MAIN TRY'

myStr = ['I','went','to','Boston']
for item in myStr:
        check(item)

我正在尝试查询select * from geo.places where text = 'Boston'（例如）。

我不断收到此错误：

    HTTP Error 505: HTTP Version Not Supported
    ERROR IN MAIN TRY

什么会导致此错误，我该如何解决？

不知道出了什么问题，但是当我尝试使用requests库执行相同的操作时，它会起作用：

>>> import requests
>>> word = "Boston"
>>> query = "select * from geo.places where text ='"+word+"'"
>>> query
"select * from geo.places where text ='Boston'"
>>> baseurl = 'http://query.yahooapis.com/v1/public/yql?q='
>>> url = baseurl + query
>>> url
"http://query.yahooapis.com/v1/public/yql?q=select * from geo.places where text ='Boston'"
>>> req = requests.get(url)
>>> req
<Response [200]>
>>> req.text
u'<?xml version="1.0" encoding="UTF-8"?>\n<query xmlns:yahoo="http://www.yahooapis.com/v1/base.rng" yahoo:count="10" yahoo:created="2014-05-17T21:12:52Z" yahoo:lang="en-US"><results><place xmlns="http://where.yahooapis.com/v1/schema.rng" xml:lang="en-US" yahoo:uri="http://where.yahooapis.com/v1/place/2367105"><woeid>2367105</woeid><placeTypeName code="7">Town</placeTypeName><name>Boston</name><country code="US" type="Country" woeid="23424977">United States</country><admin1 code="US-MA" type="State" woeid="2347580">Massachusetts</admin1><admin2 code="" type="County" woei....

请注意，两者之间存在差异，我的代码简单得多，它不适用于Cookie，并且不会伪装Safari浏览器。

如果您需要将Cookie与一起使用requests，则可以在其中找到很好的支持。
