hmget & hmset

1. 基本語法

(1) hmset(hkey ,subkey, value[, subkey, value, ...], callback)

hkey一次設置多組subkeyvalue的鍵值對資料。

(2) hmget(hkey , subkey[, subkey, ...],callback)

回傳hkey底下多組subkey對應的資料內容。

const dict = { 
    name: 'Brooks Hatlen', 
    gender: 'M', 
    age: '73' 
};

client.hmset('user:2', dict);
client.hmget('user:2', 'name', 'age', (err, vals) => {
    console.log(vals);
});
[ 'Brooks Hatlen', '73' ]
