In general to get value from map you have to do something like this:

package main

import "fmt"

func main() {
    m := map[string]string{"foo": "bar"}
    value, exists := m["foo"]
    // In case when key is not present in map variable exists will be false.
    fmt.Printf("key exists in map: %t, value: %v \n", exists, value)
}

Result will be:

key exists in map: true, value: bar
