我发现对于Tornado的用户来说没有答案:

key = self.request.query_arguments.get("key", None)

此方法必须在派生自以下处理程序的处理程序中工作:

tornado.web.RequestHandler

当无法找到所请求的键时，此方法将返回None。这为您节省了一些异常处理。

3.4 . for Python >

from urllib import parse
url = 'http://foo.appspot.com/abc?def=ghi'
query_def=parse.parse_qs(parse.urlparse(url).query)['def'][0]

import cgitb
cgitb.enable()

import cgi
print "Content-Type: text/plain;charset=utf-8"
print
form = cgi.FieldStorage()
i = int(form.getvalue('a'))+int(form.getvalue('b'))
print i

在纯Python中:

def get_param_from_url(url, param_name):
    return [i.split("=")[-1] for i in url.split("?", 1)[-1].split("&") if i.startswith(param_name + "=")][0]

def getParams(url):
    params = url.split("?")[1]
    params = params.split('=')
    pairs = zip(params[0::2], params[1::2])
    answer = dict((k,v) for k,v in pairs)

希望这能有所帮助

在原始python中解析它:

path = '/some_path?k1=v1&k2=v2&k3=v3'
_, query_string = path.split('?')
params  = dict(param.split('=') for param in query_string.split('&'))
print(params)

输出:

{'k1': 'v1', 'k2': 'v2', 'k3': 'v3'}
