Sending "Set-Cookie" in a Python HTTP server

Question

How do I send the "Set-Cookie" header when working with a BaseHTTPServerRequestHandler, and Cookie? BaseCookie and children don't provide a method to output the value to be passed into send_header(), and *Cookie.output() does not provide a HTTP line delimiter.

Which Cookie class should I be using? Two have survived into Python3, what are the differences?

Answer 1

Use C = http.cookie.SimpleCookie to hold the cookies and then C.output() to create the headers for it.

Example here

The request handler has a wfile attribute, which is the socket.

req_handler.send_response(200, 'OK')
req_handler.wfile.write(C.output()) # you may need to .encode() the C.output()
req_handler.end_headers()
#write body...
