Redis keys are presented as strings, not objects - node.js

Question

I want to get data from Redis session with nodejs - but i can't get the inner values of the objects....
this is a simple router
router.get('/page-user', function (req, res) {
console.log(redis_model.prototype.getAll());
})
and here is the model
redis_model.prototype.getAll = function () {
client.keys('*', function (err, keys) {
if (err) return console.log(err);
for(var i = 0, len = keys.length; i < len; i++) {
console.log(keys[i]);
}
});
};
So i'm getting
users
id:users
session:php:cf5myWFkDNEPwiRLpi6M1P6LqX1UPFtj //object
user:{58}
I'm trying to fetch data from the session key and i'm getting Undefined , like this:
redis_model.prototype.getAll = function () {
client.keys('*', function (err, keys) {
if (err) return console.log(err);
console.log(keys['session']); // tried also keys.session
});
};
The part that i can't figure out is why i get Type String for all the keys - like here:
redis_model.prototype.getAll = function () {
client.keys('*', function (err, keys) {
if (err) return console.log(err);
console.log(typeof keys[i]); result : //string,string, string,string
});
};
I've tried HGETALL to get the keys as objects but i still get undefined :
redis_model.prototype.getAll = function () {
client.hgetall("session",function(data){console.log(data)});
};
Here is a screenshot of the redis db...

Answer 1

Client.keys("*",function(err,keys){})
This just returns all the keys present in the redisDB which are basically strings
Instead you can use
client.get('key',function(err,data){})
inorder to get the result as an object it should be stored as a hash i.e
client.hmset("session",{'php':'cf5myWFkDNEPwiRLpi6M1P6LqX1UPFtj'}
client.hgetall("session",function(data){console.log(data.php)})
the above code gives you the value assigned to php.

Got it....
redis_model.prototype.getAll = function () {
client.get('session:php:VfAPTh_NLpBrcq3VGHTC8uT7c-sF4bQd', function(err,
result){
var foo = (JSON.parse(result))['user'];
console.log( foo);
});
};
