Fetching HTTP GET variables in Python

问题

I'm trying to set up a HTTP server in a Python script. So far I got the server it self to work, with a code similar to the below, from here.

from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer

class MyHandler(BaseHTTPRequestHandler):
    def do_GET(self):
        print("Just received a GET request")
        self.send_response(200)
        self.send_header("Content-type", "text/html")
        self.end_headers()

        self.wfile.write('Hello world')

        return

    def log_request(self, code=None, size=None):
        print('Request')

    def log_message(self, format, *args):
        print('Message')

if __name__ == "__main__":
    try:
        server = HTTPServer(('localhost', 80), MyHandler)
        print('Started http server')
        server.serve_forever()
    except KeyboardInterrupt:
        print('^C received, shutting down server')
        server.socket.close()

However, I need to get variables from the GET request, so if server.py?var1=hi is requested, I need the Python code to put var1 into a Python variable and process it (like print it). How would I go about this? Might be a simple question to you Python pros, but this Python beginner doesn't know what to do! Thanks in advance!

回答1:

urlparse.parse_qs()

print urlparse.parse_qs(os.environ['QUERY_STRING'])

Or if you care about order or duplicates, urlparse.parse_qsl().

Import in Python 3: from urllib.parse import urlparse

回答2:

Import urlparse and do:

def do_GET(self):
    qs = {}
    path = self.path
    if '?' in path:
        path, tmp = path.split('?', 1)
        qs = urlparse.parse_qs(tmp)
    print path, qs
