This is a misunderstanding caused by habitual thinking, perhaps because you're accustomed to data being passed in JSON format.

The PojoGreeter interface definition explicitly specifies the parameter type as String. Therefore, the method receives a string as data. In the implementation class PojoGreeterImpl, the received parameter is simply concatenated. Hence, the response you obtained is completely correct.

Below is the result obtained by calling the operation using the TriPojoClient from the provided sample, and the response matches yours exactly.

How should a single string parameter be passed in an http request?

This is a peculiar issue. If you've configured the Triple protocol, you should be using it for communication instead of using another protocol like HTTP.

http call also uses the triple protocol ；dubbo version : 3.3.0-beta.2

For single-parameter services, the application/json mode cannot be used. You can use text/plain, application/x-www-form-urlencoded, or application/x-www-form-urlencoded

dubbo's parameter bind not the same as spring mvc, i think this is not a problem.

The json body process first tries to take the body and decode it to the target type, and if it matches, it doesn't try to decode the json.
