JSON Question

Converting []uint8/[]byte to hash table GoLang

My server sends a JSON response which looks like shown below

{"SortAs": "SGML","GlossTerm": "Standard Generalized Markup Language","Acronym": "SGML","Abbrev": "ISO 8879:1986"}

But My Go program receives it as type []uint8 . Also the size JSON sent from the server is not of definite size , it varies . How do i convert it into a Hash table containing key/value pair again ?

Note that byte is an alias for uint8. Having said that what you want is a simple json unmarshal:

js := []byte(`{"SortAs": "SGML","GlossTerm": "Standard Generalized Markup Language", "Acronym": "SGML","Abbrev": "ISO 8879:1986"}`)

m := map[string]interface{}{}
if err := json.Unmarshal(js, &m); err != nil {

Output (wrapped):

map["SortAs":"SGML" "GlossTerm":"Standard Generalized Markup Language"
    "Acronym":"SGML" "Abbrev":"ISO 8879:1986"]

Try it on the Go Playground.
