How can I parse the following JSON structure in Go

Question

In Go, how can I parse the next JSON? I know to use structfor parsing, but the keys are different for each record, also they are not fixed, they can be more or less.

{
  "consul": [],
  "docker": [],
  "etcd": ["etcd"],
  "kubernetes": ["secure"],
  "mantl-api": [],
  "marathon": ["marathon"],
  "mesos": ["agent", "follower", "leader", "master"],
  "mesos-consul": [],
  "zookeeper": ["mantl"]
}

Thanks for the help!

Answer 1

If json values ​​are always []string, you can convert them using

json.Unmarshal(value, &map[string][]string)

But if not, the best way to do this is Unmarshal JSON in the map [string] {} interface and check each type of field you want.

Answer 2

Cancel JSON on map type: map[string][]string

var m map[string][]string
if err := json.Unmarshal(data, &m); err != nil {
    // handle error
}
