[OpenSIPS-Users] Asynchronous operation for REST queries

[Ramachandran, Agalya (Contractor)]

Hi Bogdan/Liviu,

Further debugging I got some info that I can share with you so that you can help me out easily.
Instead of calling rest_put asynchronously I have tried to call rest_post async . I could able to see that HTTP request went out(from wireshark traces) and I got 4xx response for the same.
With my code changes in place and when I call rest_put, am not seeing HTTP request sent out.
Assuming rest_put only is not working, there should be some libcurl stuffs not handled properly in 'start_async_http_req' for 'REST_CLIENT_PUT' case.
Am attaching the files I have modified. Can you please take a look guide me here.

And regarding the below error, am not seeing it every time now. It's coming now and then. Sometimes in my debug I could able to see the async_start and async_resume has executed for rest_put as well.
But the HTTP request never went to the destination.
Please let me know if you need more information on this.

Regards,
Agalya

Hi Bogdan/Liviu,

Please help on this async() to get worked at config file.
Am using rest_put() and I have added the needed functions and declarations for the same as like rest_post().

Am getting the below error if I enable debug logs.
Seems, w_async_rest_put function is called and after that it didn't process the async(rest_put)).
Do we need to configure anything specific when async() is called in config file?

Hi Liviu,

I have downloaded 2.1.4 version if opensips and trying to use rest_put call in async mode.

I have added the necessary code for rest_put () similar to rest_post() in rest_methods.c, rest_methods.h and rest_client.c

If I just call, rest_put from config file, without async it works fine. I could see rest_put() is called and do the necessary steps.

And am trying to call async from config file as,
 async(rest_put("http://***url*** <http://***url***%20> ", "$fU,$tU,$ci ", "application/json", "$var(body)", "$var(ct)", "$var(rcode)"),resume_put);

But I never see rest_put() is called. Rather am getting below error continuously.

Am I missing something here? I am sure it is a small thing. Do we need to do anything else before calling async in the script?

Agalya

Hi Agalya,

1.11 has no async support at core level. If you need that, you will have to use 2.1+

Async rest_put() is currently not implemented, but its logic would be fairly similar to the GET and POST counterparts.

Hi team,

We are using opensips1.11.3 version for our project.
I have a question here. Right now we are using a REST API call from config file for our project requirement and it is in synchronous mode currently.
