from http.server import BaseHTTPRequestHandler, HTTPServer
PORT_NUMBER = 31337
class myHandler(BaseHTTPRequestHandler):
#Handler for the GET requests

self.send_response(200)

try:

print('Started httpserver on port %s' % PORT_NUMBER)
server.serve_forever()
except KeyboardInterrupt:
print('^C received, shutting down the web server')
server.socket.close()
@brammittendorff many thanks in advance for the Python3 version, but there is a small mistake regarding the exploit:
It must use:
self.send_header('Content-type','text/html;/json')
instead of
self.send_header('Content-type','text/html')
Tested on Tor 7.5.2
Thanks!
@jorgeluengar you are right, fixed my comment thanks!
