$ _SERVER ['QUERY_STRING'] python中的等效

Question

我是一名PHP開發人員，我曾在PHP中使用$_SERVER['QUERY_STRING']獲取查詢字符串。

這是什麼Python 2.7語法？

import web 
import speech_recognition as sr 
from os import path 

urls = (
    '/voice', 'Voice' 
) 
app = web.application(urls, globals()) 


class Voice:   
    def GET(self): 
    WAV_FILE = path.join(path.dirname(path.realpath("C:\Python27")),'wavfile.wav') 

    r = sr.Recognizer() 
    with sr.WavFile("C:\Python27\wavfile.wav") as source: 
    audio = r.record(source) # read the entire WAV file 
    output = r.recognize_google(audio) 
    return output 



if __name__ == "__main__": 
    app.run() 

Answer 1

http://webpy.org/cookbook/input

user_data = web.input() 

或者使用圖書館裏urlparse：

https://docs.python.org/2/library/urlparse.html

from urlparse import urlparse 

o = urlparse('http://www.cwi.nl:80/%7Eguido?x=y') 

Answer 2

import urlparse 
url = 'http://example.com/?q=abc&p=123' 
par = urlparse.parse_qs(urlparse.urlparse(url).query) 

Answer 3

假設你正在使用web.py（你的代碼提示），你可以使用web.ctx.query（包括?）或web.ctx.env['QUERY_STRING']，這不：

import web 

urls = (
    '/', 'index', 
) 

class index: 
    def GET(self): 
     return "web.ctx.env['QUERY_STRING']: {}".format(
      web.ctx.env['QUERY_STRING']) 

if __name__ == '__main__': 
    app = web.application(urls, globals()) 
    app.run() 

見cookbook entry on ctx爲更多。
