示例1: preCheckCommand
// buf, shouldClose, handled, err
func preCheckCommand(req *redis.Request) ([]byte, bool, bool, error) {
var reply []byte
shouldClose := false
if req.Len() == 0 {
return reply, false, true, BadCommandError
}
cmd := req.Name()
switch cmd {
case "PING":
reply = []byte("+PONG\r\n")
case "QUIT":

shouldClose = true
case "SELECT":
//支持 select,但是到後台全部都用的 db 0
//hia hia hia hia 沒辦法。。。
