ethereum-rpc-demo demonstrate how to write your own RPC server base on the rpc framework provided by go-ethereum # Dependency install: `go get github.com/ethereum/go-ethereum` # Run run: `go run main.go` if server start successfully, you will get: ``` RPC HTTP endpoint opened url http://127.0.0.1:9010 cors vhosts ``` our service is registered in rpc server under the namespace `kfchen` # Test use curl to post data to RPC server ### kfchen_echo ``` curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"kfchen_echo","params":["ping"],"id":67}' http://127.0.0.1:9010 ``` Result: ``` {"jsonrpc":"2.0","id":67,"result":"ping from echo"} ``` ### kfchen_getPerson ``` curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"kfchen_getPerson","params":[{"name":"robert"}],"id":67}' http://127.0.0.1:9010 ``` Result: ``` {"jsonrpc":"2.0","id":67,"result":{"desc":"good man","name":"kfchen"}} ``` ### rpc_modules Namespace `rpc` is registered by ethereum rpc server itself when it started. We can use it to retrieve some meta info about rpc server itself. ``` curl -H "Content-Type: application/json" -X POST --data '{"jsonrpc":"2.0","method":"rpc_modules","params":[],"id":67}' http://127.0.0.1:9010 ``` Result: ``` {"jsonrpc":"2.0","id":67,"result":{"kfchen":"1.0","rpc":"1.0"}} ``` We can see `kfchen namespace` and `rpc namespace` # See Also [Ethereum JSON-RPC Wiki](https://github.com/ethereum/wiki/wiki/JSON-RPC)
