Where is a basic example?

[Serhioromano]

Do I miss anything? I can't find a basil example just connect and set value and then get the same value. Without pool or cluster. I cannot figure out even how to connect to DB.

I know that for someone pro in Golang that all is obvious, but I am first week Go developer and not everything is obvious and I need examples.

The examples in godoc cover this pretty well.
https://godoc.org/github.com/gomodule/redigo/redis#pkg-examples

Here's how to establish a new connection:

And this snippet shows you how to first write and then read a string:

Thank you. What I want is to get list rows that have keys p_1:*

Here is my code

       conn, err := redis.DialURL("redis://172.17.0.1:6379")
	defer conn.Close()

	if err != nil {
		panic(err.Error())
	}

	res, err := conn.Do("KEYS", "p_1:*")

	if err != nil {
		panic(err.Error())
	}

	res, err = redis.Values(conn.Do("MGET", res))
	if err != nil {
		panic(err.Error())
	}

	fmt.Println(res)

res has something that looks like array of byte when I get keys. But I cannot get those keys values.

Look at the docs that I linked to in my earlier post, when reading a string with "GET" you should use the conversion function redis.String() to convert the bytes result into a Golang string.

[Serhioromano]

First, let me say how I am thankful for your time.

I looked at docs but I can't get it. When I get keys I have a result. But when I MGET I have nil

I do not use GET. I use KEYS and that supposed to return array so perhaps I have to convert KEYS to something else.

Could you look at my code and tell what is missing?

You want:

	keys, err := redis.Strings(conn.Do("KEYS", "p_1:*"))
	if err != nil {
		panic(err.Error())
	}

	for _, k := range keys {
		fmt.Println(k)
	}

[Serhioromano]

@stevenh yes that ш can do. ш can list of keys. I cannot convert this list to appropriate format to use MGET

[stevenh]

no conversion needed just pass the result using variadic expansion e.g.

vals, err := redis.Values(conn.Do("HGET", keys...))
