Python, HTTPS (SSL), tlslite and POST method (and lots of pain)
yat...@gmail.com
Since quite long time I'm trying to achieve following things:
- for some sort of testing I need webserver with https access
- with POST method implemented
I found something which fits it in nicely written in Python,
connected
my toys and... server hangs in some weird "inter-state" while serving
POST method
Below server code:
-------------------------
#!/usr/bin/python
from SocketServer import *
from BaseHTTPServer import *
from SimpleHTTPServer import *
from tlslite.api import *
import string,cgi,time
from os import curdir, sep
s = open("./server.pem").read()
x509 = X509()
x509.parse(s)
certChain = X509CertChain([x509])
s = open("./server.pem").read()
privateKey = parsePEMKey(s, private=True)
sessionCache = SessionCache()
#class MyHandler(BaseHTTPRequestHandler):
class MyHandler(SimpleHTTPRequestHandler):
def do_POST(self):
global rootnode
try:
ctype, pdict = cgi.parse_header(self.headers.getheader
('content-type'))
form = cgi.FieldStorage(fp = self.rfile,
headers=self.headers,
environ={'REQUEST_METHOD':'POST',
'CONTENT_TYPE':self.headers
['content-type']} )
if ctype == 'multipart/form-data':
if form.has_key('postdata'):
temp_file = open(form['postdata'].filename,'wb')
buffer = form['postdata'].file.read()
temp_file.write(buffer)
temp_file.close()
self.send_response(200)
#set apriopriate header if you want send
something
#self.send_header('Content-type', 'text/plain')
self.send_header('Content-type', 'text/html')
self.end_headers()
#... and send it
#self.wfile.write('OK')
self.wfile.write('<html><body>Post OK.</body></
html>')
except :
pass
class MyHTTPServer(ThreadingMixIn, TLSSocketServerMixIn, HTTPServer):
def handshake(self, tlsConnection):
try:
tlsConnection.handshakeServer(certChain=certChain,
privateKey=privateKey,
sessionCache=sessionCache)
tlsConnection.ignoreAbruptClose = True
return True
except TLSError, error:
print "Handshake failure:", str(error)
return False
httpd = MyHTTPServer(('127.0.0.1', 443), MyHandler)
#httpd = HTTPServer(('127.0.0.1', 80), MyHandler)
httpd.serve_forever()
--------------------
And page which is used to serve POST request:
<html>
<body>
<form method='POST' enctype='multipart/form-data'
action='./'>
File to post: <input type=file name=postdata><br><br>
<input type=submit value=Send>
</form>
</body>
</html>
File is being nicely send to server but as I've mentioned above
server
is halted in some interstate. Only after Ctrl+C terminates it
confirmation of successful transmition is showed in web browser
Choosing to use server without SSL (HTTPServer instead of
MyHTTPServer) makes everything work without glitch.
I would be happy to hear any suggestions
If somebody knows any alternative to achieve similar thing (https +
POST method on server side) it would be enough to get my tests
working.
Thx in advance

sorry for repost - I've made mistake and tried correct it just after
posting by deleting it. If it confuses somebody then again - sorry for
that

So just for other fighting the same thing:
Instead of using tlslite use pyOpenSSL and as a base for your server
you can use:

When you add do_POST method everything works
