Param：

  • node (string, required)

  • command (string, required)

addnode "node" "add|remove|onetry"

Attempts add or remove a node from the addnode list. Or try a connection to a node once.

Arguments:
1. "node"     (string, required) The node (see getpeerinfo for nodes)
2. "command"  (string, required) 'add' to add a node to the list, 'remove' to remove a node from the list, 'onetry' to try a connection to the node once
