Re: [mh] RoomMe

Thank you for making my comment more useful! :)

One other suggestion, wrap the decode_json in a eval loop. MH will hard crash if the json received is malformed.

If you are creating a library, you need to give the sub the main context (ie sub main::my_new_sub), from what I recall the http_server.pl doesn’t see subroutines out of the main scope.

There are no parameters being passed to the sub.  However, inside the sub, I am creating a local hash of the body of the web request with the following:

Take a look at main::razberry_push in the razberry package, and I think I parse post data in the json_server.pl. (It’s been a while since I’ve looked at the json server code)
