Ethereum JSON-RPC

1 Ethereum RPC APIs

1) Standard APIs

2) Geth Specific APIs

2 Ethereum RPC

1) HTTP-RPC：手动启动
--rpc
--rpcaddr
--rpcport
--rpcapi
--rpccorsdomain
2) WS-RPC：手动启动
--ws
--wsaddr
--wsport
--wsapi
--wsorigins
3) IPC-RPC：自动启动
--ipcdisable
--ipcapi
--ipcpath
注：出于安全考虑，接口默认开放API子集，通过相应参数可以进行配置。

3 HTTP-RPC 调用实例

# 运行以太坊私有链节点并配置参数
docker run -it -d --name eth-noderpc -p 30303:30303 -p 8545:8545 --net eth-network --ip  172.25.0.10 ethereum:3.0 --rpc --rpcaddr "0.0.0.0" --rpcapi "admin,debug,eth, miner,net,personal,shh,txpool,web3" --nodiscover --networkid 15
注：

--rpc 启用HTTP-RPC服务

--rpcaddr 服务监听接口，默认“localhost”

--rpcapi 配置可使用的api接口，默认“eth, net, web3”
