SMPP to HTTP (intercept?)

[Alex]

Hello,

I red that SMPP to HTTP is not possible in current Jasmin project. As a solution, I saw "interceptor" which can be linked to a script. This would allow me to handle incoming SMPP messages inside my platform (HTTP call or direct DB insert).

The main question I have is about DLR. Is there a DLR generator (best would be an HTTP DLR API)?

What I want: (my customers) -> SMPP (Jasmin) -> HTTP (my platform)

but this is not possible so I think of:   (my customers) -> SMPP (Jasmin) -> Interceptor (Jasmin) -> Python script -> HTTP(my platform)

This should work for SMS-MT sending but the question is about DLR.

I would like to have (my platform) -> HTTP(Jasmin) -> SMPP (my customers)  to return them DLRs.

Can it be done through current Jasmin?

PS:

- my current country carriers doesn't have SMPP, they use exotic APIs so I absolutely need to go inside my platform

- my customers (some of them) absolutely need SMPP to route traffic to my direct routes

- I'm only talking about MT, MO doesn't exist in my current country (on carrier API side)

Thanks!

The way you want to do it is possible, but some points to take care of:

• Interception occurs before routing, so if you have multiple http upstreams, you'll need to implement a sort of routing logic inside your interceptor script,
• Forwarding DLRs is simple, you'll need to inject message in RabbitMQ, Jasmin will take it in charge and push it through smpp to your client,

I think it's simpler you do the following:

Client --------> Jasmin ----------> SMPP Simulator (it can be another Jasmin instance, or even SMPPSim from Logica)

1. Consume messages going to smpp simulator (through RabbitMQ) and push them through http, your script will be very simple,
2. Get DLR from your platform and publish it to RabbitMQ

Hi zoufou,

Thanks for your answer.

• ok for interception, if I get user it's enough (routing is done inside my platform)
  
• for the DLR part, is there some doc about DLR injection? I noticed that jasmin doc is very light so if you have some extra doc (with samples for ex), it would be a great help :)

Thanks!

This discussion will help you, it is an example of implementing logics on top of Jasmin's async messaging.

have you tried to implement through interceptor?

[Alex]

well, i'm not familiar with python so I tried to find for some existing scripts ;)

also i'm worried about dlr injection since it seems a bit complex.

if you have some sample scripts i'm interested :)

I tried interceptor to handle the first part of my SMPP to HTTP project.

However, interception is not working. I have the following information which should mean it works.

tail /var/log/jasmin/interceptor.log

I've configured it with "python2(..../interceptor.py)".

interceptor.py script :

routable.pdu.params['source_addr'] = 'ALEX'

(I tried several code, for example the one to set logger but none worked so I'm wondering if it is due to CentOS7 or if there is missing settings.)

I'm setting interceptor without filter, is it ok? I wish to intercept ALL MT traffic to my script (to call my URL).

Thank you!

Hi Alex, you can set the logging level to DEBUG in the interceptor and check what's happening.

[Alex]

I set to DEBUG and got following log

2015-12-09 11:59:47 DEBUG    15383 Running [smpp_status = 0

]

Where can i see the script error? Or the fact the script has been called?

Thanks!

[Alex]

The script works when I try in bash but doesn't seem to be called as there is neither log or error.

interceptor.py

"This is how logging is done inside interception script"

import logging

# Set logger

logger = logging.getLogger('logging-example')

if len(logger.handlers) != 1:

    hdlr = logging.FileHandler('/var/log/jasmin/some_file.log')

    formatter = logging.Formatter('%(asctime)s %(levelname)s %(message)s')

    hdlr.setFormatter(formatter)

    logger.addHandler(hdlr)

    logger.setLevel(logging.DEBUG)

logger.info('TEST')
