Alternative of coder.extr​insic(webw​rite) in Simulink when running model on hardware

I am using the following code in my Simulink model which is running on raspberry pi hardware:

coder.extrinsic('webwrite');  
 url = 'http://alnnovative.com/rts.alnnovative.com/security.php';
response = webwrite(url, "marium", "post");

When I searched through web, I found out that in external mode, code has to generated and coder.extrinsic does not generate code in external mode. So what alternative can I use in this case?

Same here. Also looking for an alternative for webwrite on arduino.

tried manually reverse engineering on the webwrite function but thats syssiphus. Maybe a third Party input for C or C++ could help. Found this: https://whoshuu.github.io/cpr/introduction.html#get-requests
