[OpenSIPS-Users] Support for https in async

[Ramachandran, Agalya (Contractor)]

Hi Liviu,

Thank you for response. I have few questions, can you please clarify me on these.


*         Is there is a roadmap in future targeting async() to handle https queries?

*         In start_async_http_request(), why is curl_multi_wait is not used to overcome 1024 fds limitation? and is there plan to use it in future?

*         What is the use of read_fds[] in rest_methods.c and who uses it?

*         Why select() is not used ?


Regards,
Agalya

Hi, Agalya!

We have not done any development in that direction, and I assume it won't work out of the box, as we need to instruct libcurl on where to find the CA certificate before we can expect it to establish the TLS connection. As an alternative, we could add the option of disabling host/peer verifications like here [1]

Hi team,

Have you tried with https://url with async and does that work without issue ?
When I try, resume_async_http_req is called, but crash is occurring at libcurl library. So helpless to debug further.
async(rest_put("https://url"<https://url>, "$fU,$tU,$ci ", "application/json", "$var(body)", "$var(ct)", "$var(rcode)"),resume);

My question is crash occring only in my scenario or  OpenSIPS doesn't support async as https?
Here is my dump just in case for reference.

Hi team,

Just a quick question.. Does async(), method supports https request?
When I try to use https, resume_async_http_req is called, but I never got the response and rather OpenSIPS crashed at libcurl.

Agalya
