Geth allows me to define & load my own custom JavaScript functions with --preload flag or require() on Geth console.
But is there way to access my functions via RPC interface?
Like :
curl -H "Content-Type: application/json" \
--data '{"jsonrpc":"2.0","method":"mycustom_function()","params":[],"id":123}'
I've seen i can open access to more management APIs with --rpcapi eth,web3,admin,eth,miner but it doesnt work for my custom functions.
--preload is an easy way to add commonly used functions and objects to geth console. You cannot access them using RPC interface.
For example, if you are interacting with a contract deployed at address addr with ABI abi, you can create a file with MyContract = web3.eth.contract(abi).at(0x1) and preload it using --preload. So you can simply access your contract method using MyContract object inside geth console.
