Hello everyone,
I work on Linux #astra31+ci49-Ubuntu with GNU/Linux.
On my system installed curl 7.68.0 (x86_64-pc-linux-gnu) libcurl/7.68.0 OpenSSL/1.1.1k zlib/1.2.11 brotli/1.0.7 libidn2/2.0.5 libpsl/0.20.2 (+libidn2/2.0.5) libssh2/1.11.0 nghttp2/1.36.0 librtmp/2.3.
From this system I can get the data from some device usung console request to the private https server via the curl command:
curl -k -X GET -H 'Authorization: Bearer nokey' https://<IP-address>:<port>/api/ccu/online
I’ve found, how to get data from this server, using libcurl calls. But I need additionally to POST some data to this server using JSON-format.
Using console request:
curl -k -X POST -d ‘{«1»:0}’ -H ‘Content-type: application/json’ -H ‘Authorization: Bearer nokey’ https://<host>:Port/api/ccu/outputs
I can change some output registers of the device, via this server. Is it possible anyhow using some options of libcurl to POST data to this device in JSON-format, like it is done in the previous curl console command?
Thanks in advance!
