Accessing Restful API

Added by Bert Cuypers about 4 years ago

Hi all,

Which is the best way in Wt to access a (non-Wt) Restful API? Should JS be used, or are there other methods?

Thanks in advance!

Best regards,

Bert

Usually we're doing the communication with APIs server side, using Wt::Http::Client. It's a fairly simple one that suffices for many uses. Other C HTTP client libraries exist if Wt's doesn't suffice though.

Hi Roel,

This is exactly what I needed! Thanks a lot!

Best regards,

Hi Roel,

Is it also possible to use this Wt::Http::Client without any WApplication object existing?

I'd like to have communication with the APIs at night when there are no users connected with my app...

Thanks in advance

Best regards,

Bert

Yes. All the HTTP client needs is an io_service. If you create one with the default constructor inside of a WApplication it will automatically use the io_service of the WServer (and post all of its events to that WApplication).

Use this constructor with an io_service for which at least one thread is running run() to create a Client outside of a WApplication: https://www.webtoolkit.eu/wt/doc/reference/html/classWt_1_1Http_1_1Client.html#a966378bd63f2babf2f8d2beb2783e45e.
