Hi ,
I have requirement to simulate http server on particular port 
we have an application which sends req to that simulated server for that port 
I need to get that request 
read the request body 
Validate the request body
and send response back to the appln from the simulated server based on the validation 

I want to do all this in robot framework 

I'm using BaseHTTPServer module to simulate the server 
my code is as follows 

#!/usr/bin/python
import sys
simulator_server_ip=sys.argv[1]
simulator_server_port=sys.argv[2]

from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler
from SocketServer import ThreadingMixIn
import threading


class Handler(BaseHTTPRequestHandler):

    def do_POST(self):
        print "getting data section"
        content_len = int(self.headers.getheader('content-length', 0))
        self.req_body = self.rfile.read(content_len)
        return self.req_body


    def sendresponse_code(self,code):
        print "response section"
        self.send_response(code)
        self.end_headers()
        message =  threading.currentThread().getName()
        self.wfile.write(message)
        self.wfile.write('\n')
        return

class ThreadedHTTPServer(ThreadingMixIn, HTTPServer):
    """Handle requests in a separate thread."""

if __name__ == '__main__':
    server = ThreadedHTTPServer((simulator_server_ip,int(simulator_server_port)), Handler)
    req,c_a=server.get_request()
    hlr=Handler(req,c_a,server.server_address)
    print hlr.req_body      # this is the request body which needs to be validated outside the code
    resp_code=input("send the code:")  # based on the validation I need to send the response which is handled from outside 
    hlr.sendresponse_code(resp_code)

</code>

when I run the above code , in send_response section it is failing and 
I'm getting the following error 

getting data section
{"push-message":"json_data_too_many_parameters_so_not_pasting_the_Data"}
send the code:200

can some one Please check and let me know what is wrong with the code

Hi, this is for tracking bugs in the Python interpreter and standard library, not asking for help debugging your own code. There's no reason (yet) to believe this error is a bug in Python, you need to debug it first to ensure it is not a bug in your own code before posting it as a bug here.

If you need help debugging your code, try the python-list@python.org mailing list.

If you find that it is not a bug in your code, please re-open this issue.
