Simple Python Webserver to save file

Question

I'm trying to make a simple python webserver to save text that is Posted to a file called store.json which is in the same folder as the python script. Here is half of my code, can someone tell me what the rest should be?

import string,cgi,time
from os import curdir, sep
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
#import pri

class StoreHandler(BaseHTTPRequestHandler):
def do_GET(self):
    try:
        if self.path == "/store.json":
            f = open(curdir + sep + "store.json") #self.path has /test.html
            self.send_response(200)
            self.send_header('Content-type','text/json')
            self.end_headers()
            self.wfile.write(f.read())
            f.close()
            return
        return
    except IOError:
        self.send_error(404,'File Not Found: %s' % self.path)
def do_POST(self):
    //if the url is 'store.json' then
    //what do I do here?

def main():
    try:
        server = HTTPServer(('', 80), StoreHandler)
        print 'started...'
        server.serve_forever()
    except KeyboardInterrupt:
        print '^C received, shutting down server'
        server.socket.close()
if __name__ == '__main__':
    main()

Here's the general idea:

from os import curdir
from os.path import join as pjoin

from http.server import BaseHTTPRequestHandler, HTTPServer

class StoreHandler(BaseHTTPRequestHandler):
    store_path = pjoin(curdir, 'store.json')

    def do_GET(self):
        if self.path == '/store.json':
            with open(self.store_path) as fh:
                self.send_response(200)
                self.send_header('Content-type', 'text/json')
                self.end_headers()
                self.wfile.write(fh.read().encode())

    def do_POST(self):
        if self.path == '/store.json':
            length = self.headers['content-length']
            data = self.rfile.read(int(length))

            with open(self.store_path, 'w') as fh:
                fh.write(data.decode())

            self.send_response(200)


server = HTTPServer(('', 8080), StoreHandler)
server.serve_forever()

$ curl -X POST --data "one two three four" localhost:8080/store.json
$ curl -X GET localhost:8080/store.json    
one two three four%
