[otrs] Generic REST Interface TicketUpdate function with python

27 Nov 2014

      hi guys,

im playing around with the new REST Interface struggling to find out how 
to pass valid data to the TicketUpdate function. I can read the
TicketData with the TicketGet function without any problems, but fail
to update any ticket information.

I have registered the WS as following:
...

Debugger:
  DebugThreshold: debug
  TestMode: '0'
Description: ''
FrameworkVersion: 4.0.1
Provider:
  Operation:
    TicketGet:
      Description: ''
      MappingInbound:
        Type: Simple
      MappingOutbound:
        Type: Simple
      Type: Ticket::TicketGet
    TicketUpdate:
      Description: ''
      MappingInbound:
        Type: Simple
      MappingOutbound:
        Type: Simple
      Type: Ticket::TicketUpdate
  Transport:
    Config:
      KeepAlive: ''
      MaxLength: '20000000'
      RouteOperationMapping:
        TicketGet:
          Route: /TicketGet/:TicketID
        TicketUpdate:
          RequestMethod:
          - POST
          Route: /TicketUpdate/:TicketID
    Type: HTTP::REST
RemoteSystem: ''
Requester:
  Transport:
    Type: '
And i try to access the TicketUpdate Function via python, short
snipped like this:

<imports>
...
ticketdata = dict(
        UserLogin='username',
        Password='username',
        Data=dict(
            Ticket=dict(
                Title='changeme'
                ))
        )
url = 'http://myotrs/otrs/nph-genericinterface.pl/Webservice/Test/TicketUpdate/1001...'
r = requests.post(url, params=ticketdata)
print r.content
And the TicketUpdate function returns like:
...
{"TicketNumber":"2014112680000111","TicketID":"10017"}
but does not change anything in the Ticket and does not
error out.

Looking at the debugger it seems clear that not all data
is passed in my post request:
...
Incoming data before mapping (2014-11-27 10:41:34, debug)
$VAR1 = {
  'Data' => 'Ticket',
  'Password' => 'username',
  'RequestMethod' => 'POST',
  'TicketID' => '10017',
  'UserLogin' => 'username'
};
Incoming data after mapping (2014-11-27 10:41:34, debug)
$VAR1 = {
  'Data' => 'Ticket',
  'Password' => 'username',
  'RequestMethod' => 'POST',
  'TicketID' => '10017',
  'UserLogin' => 'username'
};
but i struggle to find out how to pass it rightfully?
Passing a json.dumps() generated data string will error
out and urlencoding seems not the right way. Can someone
give me a pointer here? Thanks!
