[jira] [Updated] (CAMEL-21339) Client request validation and empty body

["Olivier Jacquemart (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CAMEL-21339?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Olivier Jacquemart updated CAMEL-21339:
---------------------------------------
    Description: 
If you enable the client request validation at a global level, and have a GET rest endpoint, there is no need for a body validation.

The problem is if the client sends the Content-type aplication/json. The Content-Type is not needed tbut I got the issue because a client sends this header all the time and I can't change it.

I faced the issue while upgrading an application from 3.20.6 to 4.8.0. I

Here are curl examples:
{code:java}
# succeeds
$ curl localhost:8080/api/hello
{"message":"hello world"}

# fails
$ curl -H "Content-Type: application/json" localhost:8080/api/hello
Invalid JSon payload.{code}
 

In the problematic case, the [DefaultRestClientRequestValidator|https://github.com/apache/camel/blob/main/core/camel-support/src/main/java/org/apache/camel/support/processor/DefaultRestClientRequestValidator.java] will try to deserialize the json against an empty string and will fail because it's not a valid json.
