By default, RPC API
listens on 20336
port.
The following option can be used to change the port at which the client side RPC API
listens:
Copy ontology --rpcport 1024
The following option can be used to stop the client side RPC
service:
Copy ontology --disable-rpc
Remote Procedure Call (RPC), also known as function call or subroutine call, are used on one machine on a network to request services from another machine without the need of detailed network information.
Interface definition
The JSON-RPC
interface definition is as follows:
Request parameters
The structure of the request message is as follows:
Method list
Get the hash of the highest block for the current node
height or blockhash,[verbose]

Verbose can be 0 or 1, response is different
Get block hash by block height
Get the current number of connections for the node
Returns the corresponding transaction information based on the specified hash value.
