rpc.org">JSON-RPC is a lightweight RPC mechanism using
JSON as a data language for request and reply messages. It is rapidly becoming a standard in web development, where it is used to make RPC requests over HTTP. RabbitMQ provides an AMQP transport binding for JSON-RPC in the form of the
JsonRpcClient
class. JSON-RPC services are self-describing - each service is able to list its supported procedures, and each procedure describes its parameters and types. An instance of JsonRpcClient retrieves its service description using the standard
system.describe
procedure when it is constructed, and uses the information to coerce parameter types appropriately. A JSON service description is parsed into instances of
ServiceDescription
. Client code can access the service description by reading the
serviceDescription
field of
JsonRpcClient
instances.
