在redis中我们一般存储string、list、hash类型的值，对应的方法分别为 db.StringGet(“key”)、db.ListRange、db.HashGetAll 如果取list类型值时使用了string的方法就会报WRONGTYPE Operation against a key holding the wrong kind of value错误。

redis报错WRONGTYPE Operation against a key holding the wrong kind of value,Redis,redis,redis读string,redis读list、hash

redis-cli命令窗口

#读取string类型的值
get "qwer"
#读取list hash表中data的值
hget "c:System.String,k:InternalMenuJson" data
#读取list hash表中所有的值
hgetall "c:System.String,k:InternalMenuJson"
