JavaScript Console¶

Interactive Use: The Console¶

连接:

$ geth console
$ geth attach

指定ipc连接:

# geth attach /some/custom/path.ipc
# geth attach http://191.168.1.1:8545
# geth attach ws://191.168.1.1:8546

注:

默认不打开rcp端口, 可以用
1. geth结点启动时指定: --rpcapi and --wsapi
2. 使用命令 admin.startRPC and admin.startWS.
   > admin.startRPC("127.0.0.1", 8545)
  true
  > admin.startWS("127.0.0.1", 8546)
  true

Non-interactive Use: Script Mode¶

简单实例:

$ geth attach --exec "eth.blockNumber"

复杂实例:

$ geth attach http://geth.example.org:8545 --exec 'loadScript("/tmp/checkbalances.js")'
$ geth attach http://geth.example.org:8545 --jspath "/tmp" --exec 'loadScript("checkbalances.js")'
