[Wiphat101]

Hi, everyone
I want to get values ​​from Ui in the format [{"x":758,"y":128},{"x":772,"y":491}] using Cgi. What are the steps?
"acap-sdk version" : 3.5
"schemaVersion" : 1.3
thank

Could you please explain it more.

[Wiphat101]

Yes, correct

[Cacsjep]

did you see this ? https://github.com/AxisCommunications/acap-native-sdk-examples/tree/main/web-server-using-fastcgi

[Wiphat101]

I have seen this but do you have a way to use it with the opc-ua-colorchecker-acap example? Because I am using CGI data transmission from this example.

OK, did you See this ? https://github.com/AxisCommunications/opc-ua-colorchecker-acap/blob/2dab70f13a359b5072275413fbd4700629c8c77a/src/opcuacolorchecker.cpp#L497 i think you need to add an new cgi path to your manifest and then add in the request handler where you check against the new cgi path like here: https://github.com/AxisCommunications/opc-ua-colorchecker-acap/blob/2dab70f13a359b5072275413fbd4700629c8c77a/src/opcuacolorchecker.cpp#L514

Here in manifest you need to add the new cgi path: https://github.com/AxisCommunications/opc-ua-colorchecker-acap/blob/2dab70f13a359b5072275413fbd4700629c8c77a/manifest.json#L21

If I want to get the polygon drawing position from the front end using an array variable, what should I do? Because of this value There will be at least 4 sets: [x1,y1... x4,y4]

Just mentioning that it should be possible to convert the color checker example to use ACAP Native SDK and FastCGI.
In ACAP Native SDK you also have a supported JSON library jansson that could perhaps be used by the CGI for polygon data.
It's a bit of work to do it of course.
