Python HTTP 错误 505 : HTTP Version Not Supported

Question

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)。

我一直收到这个错误:

    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？

Answer 1

您构造的 URL 不是有效的 URL。你发送的是

GET /v1/public/yql?q=select * from geo.places where text ='I'&diagnostics=true HTTP/1.1
Accept-Encoding: identity
Host: query.yahooapis.com
Connection: close
User-Agent: Safari/7.0.2

URL 中不应有空格，例如您必须进行正确的 URL 编码(用“+”等替换空格)。我想 requests 只是为您修复了错误的 URL。
