how to collect http body params

[cxbiao]

My Skywalking version is 7.0.0
I know plugin.springmvc.collect_http_params can only collect http get params and post params (application/x-www-form-urlencoded)
but can't collect application/json params。

I want to know how to collect body params in content-type (application/json)。

if there are any optional plugin can implement my requirement,please tell me。
Thanks！

No, we don't have that. Because the plugin would affect all HTTP request, collecting the body is super dangerous. I would recommend you to use our application toolkit API in your own filter, and tag the value into the span.

This explanation should not by us. Read how servlet and http stream work.
