does http_client source support json body in post method？

[lddlww]

i found http_client source support method， but can't find body parameter when method is post

for example：

curl -u root: \
  --request POST \
  '127.0.0.1:8001/v1/query/' \
  --header 'Content-Type: application/json' \
  --data-raw '{"sql": "SELECT avg(number) FROM numbers(100000000)"}'
