如果只有telnet（而不是’redis-cli’），则需要使用Redis二进制安全统一协议在键名中使用空格，例如：
telnet localhost 6379*2$3GET$17field with spaceshello (this is Redis answer if "field with spaces" contains value "hello")Explanation:*2 = Number of arguments (first arg is "GET" and second is "field with spaces")$3 = length of first argument ("GET" contains 3 bytes)$17 = length of second argument ("field with spaces" contains 17 bytes)有关Redis二进制安全协议的更多信息：http :
