BaseHTTPServer and do_POST method

[rocksportrocker]

Hi,

I am trying to implement a local server for storing and retrieving
numerical data.
So I use BaseHTTPServer as follows:

---------------------------------------------------------
from BaseHTTPServer import *

class Handler(BaseHTTPRequestHandler):

def do_POST(self):

print "POST"
self.send_response(200)


httpd = HTTPServer(("",8000), Handler)
httpd.serve_forever()
---------------------------------------------------------

For testing I use:

---------------------------------------------------------

import httplib


data = "123456789o" * 100

conn = httplib.HTTPConnection("localhost:8000")
print conn.request("POST", "/", data)

---------------------------------------------------------------

Executing this client, the server says:

error(10053, 'Software caused connection abort')

If I add "conn.getresponse()" at the end of the test script, the
message disapears, but the server hangs.

Where is my mistake ?

Greetings, Uwe.

I don't get that error. On the server, I get the output:

POST
localhost - - [27/Feb/2008 06:49:13] "POST / HTTP/1.1" 200 -

and on the client I get:

None

I don't know what's causing the second line of output on the server.

In my case the server says:

If I ommit send_response() in do_POST() I get no
errormessage. That is an acceptable solution for me.

If you don't add that line, the client process exits and drops the
connection, and the server detects that situation when it tries to send
the response to a dead socket.
The server "hangs" because you told it to "serve_forever"; it's waiting
for the next request. Use Ctrl-C to stop it.
You may find easier to use urllib or urllib2 to write the client.
