GetString safely extracts a string from a nested map path. Usage: GetString(data, "user", "name") is equivalent to data["user"].(map[string]interface{})["name"].(string)

(m map[string]interface{}, keys ...string)

// Usage: GetString(data, "user", "name") is equivalent to
// data["user"].(map[string]interface{})["name"].(string)
func GetString(m map[string]interface{}, keys ...string) string {
	if len(keys) == 0 {
		return ""
	}
	v := navigate(m, keys[:len(keys)-1])
	if v == nil {
		return ""
	}
	s, _ := v[keys[len(keys)-1]].(string)
	return s
}

// GetFloat safely extracts a float64 (the default JSON number type).
