Convert Redigo Pipeline result to strings - go

Question

I managed to Pipeline multiple HGETALL commands, but I can't manage to convert them to strings.
My sample code is this:
// Initialize Redis (Redigo) client on port 6379
// and default address 127.0.0.1/localhost
client, err := redis.Dial("tcp", ":6379")
if err != nil {
panic(err)
}
defer client.Close()
// Initialize Pipeline
client.Send("MULTI")
// Send writes the command to the connection's output buffer
client.Send("HGETALL", "post:1") // Where "post:1" contains " title 'hi' "
client.Send("HGETALL", "post:2") // Where "post:1" contains " title 'hello' "
// Execute the Pipeline
pipe_prox, err := client.Do("EXEC")
if err != nil {
panic(err)
}
log.Println(pipe_prox)
It is fine as long as you're comfortable showing non-string results.. What I'm getting is this:
[[[116 105 116 108 101] [104 105]] [[116 105 116 108 101] [104 101 108 108 111]]]
But what I need is:
"title" "hi" "title" "hello"
I've tried the following and other combinations as well:
result, _ := redis.Strings(pipe_prox, err)
log.Println(pipe_prox)
But all I get is: []
I should note that it works with multiple HGET key value commands, but that's not what I need.
What am I doing wrong? How should I do it to convert the "numerical map" to strings?
Thanks for any help

Answer 1

Each HGETALL returns it's own series of values, which need to be converted to strings, and the pipeline is returning a series of those. Use the generic redis.Values to break down this outer structure first then you can parse the inner slices.
// Execute the Pipeline
pipe_prox, err := redis.Values(client.Do("EXEC"))
if err != nil {
panic(err)
}
for _, v := range pipe_prox {
s, err := redis.Strings(v, nil)
if err != nil {
fmt.Println("Not a bulk strings repsonse", err)
}
fmt.Println(s)
}
prints:
[title hi]
[title hello]

Answer 2

you can do it like this:
pipe_prox, err := redis.Values(client.Do("EXEC"))
for _, v := range pipe_prox.([]interface{}) {
fmt.Println(v)
}
