So I've got the following bit of JSON and I want to pull out the "$t" value under "token". Continue for Go code...
{
"@encoding": "iso-8859-1",
"@version": "1.0",
"service": {
"auth": {
"expiresString": {
"$t": "2013-06-12T01:15:28Z"
},
"token": {
"$t": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
},
"expires": {
"$t": "1370999728"
},
"key": {
"$t": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}
}
}
I have the following snippet of Go code that unmarshals the json into an interface. Then I work my way down to the "$t" value of "token". This approach does work, but it's ugly.
My question: is there a faster way to access that value than by converting each map into an interface? I'm very new to Go and am not aware of many of the useful features of interfaces and maps.
var f interface{}
jerr := json.Unmarshal(body, &f)
m := f.(map[string]interface{})
ser := m["service"].(map[string]interface{})
a := ser["auth"].(map[string]interface{})
tok := a["token"].(map[string]interface{})
token := tok["$t"]
fmt.Fprintf(w, "Token: %v
", token)
Thanks in advance!
