Any working sample code of using http GET-request?

2

libcurl provides and example they describe as Simple https GET

There is also a httpGet sample app that’s part of Legato.

Trying to run HttpGet sample gives:
Jan 6 00:20:39 | supervisor[654]/supervisor T=main | app.c CreateFileLink() 1485 | Could not stat file at ‘/etc/resolv.conf’. No such file or directory
Jan 6 00:20:39 | supervisor[654]/supervisor T=main | app.c CreateFileLink() 1588 | Failed to create link at ‘/etc/resolv.conf’ in app ‘httpGet’.

Propably I have something wrong with my environment, how to find resolv.conf? ( im using Win DS, module 7702)

Hi All,

I need some quick help on this. This app is not working.
This is the legato version 18.07.0-2-g3d867cd9_8cbd288d69eeddef221f1c21dd15683d_modified using on WP7608 module.

Actually, it was working earlier. I had developed a POST functionality. Even that is also not working.

Did anyone try this on the recent 18.07.0 release?
Did something happen on the DataServices in 18.07.0?

Need help urgently. Going for a demo this weekend.
Here is the log.

@dfrey, will you be able to throw some light on this?

Thanks
