如何在shell中curl一个带变量的post请求

有时候，我们想在一个shell中，执行一段脚本，循环post一段json数据，而且body里面的字段名和值都可以是一个变量应该怎么做？


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}'
