I am using following cgi script written in python for running an HTTP server. Its working fine. do_POST function is being invoked on making post request. However I am not able to receive the post variables on server side. I am trying to fetch post variables by these statements(found them here):
postData = cgi.FieldStorage()
fname = postData.getvalue("fname")
when I print fname and postData. I get following output:
FieldStorage(None, None, [])
None
The full script is:
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
import SocketServer
import cgi
class S(BaseHTTPRequestHandler):
def _set_headers(self):
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers()
def do_GET(self):
self._set_headers()
self.wfile.write("<html><body><h1>hi!</h1></body></html>")
def do_HEAD(self):
self._set_headers()
def do_POST(self):
self._set_headers()
postData = cgi.FieldStorage()
print postData
print postData.getvalue("fname")
self.wfile.write("<html><body><h1>POST!</h1></body></html>")
def run(server_class=HTTPServer, handler_class=S, port=80):
server_address = ('', port)
httpd = server_class(server_address, handler_class)
print 'Starting httpd...'
httpd.serve_forever()
if __name__ == "__main__":
from sys import argv
if len(argv) == 2:
run(port=int(argv[1]))
else:
run()
I have tried to make post request in following two ways.
1) curl -d "fname=bar&lname=baz" http://localhost
2) By using following HTML page:
<form action="http://localhost" method="post">
First name: <input type="text" name="fname"><br>
Last name: <input type="text" name="lname"><br>
<input type="submit" value="Submit">
</form>
In both ways the client receives the correct response, but the post variables are not accessible on server side. Any help is appreciated.
