How to curl a post request with variables in the shell

Sometimes, we want to execute a script in a shell, post a piece of json data in a loop, and the field name and value in the body can be a variable. What should we do?


test.sh

id=1111
name="ct"
curl http://192.1.13.100:8888/dataservice/knowledge/createKP  -H "Accept: application/json"  -H "Content-Type: application/json"  -d '{"kpId":"'"$id"'","kpName":"'"$name"'","description":"desc","path":"0-1-","sort":1,"version":1,"parentKPId":
1}'
