You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: map_claims.go
    path of file: ./repos/kubeedge/vendor/github.com/golang-jwt/jwt
    
    the code of the file until where you have to start completion: package jwt

import (
	"encoding/json"
	"errors"
	// "fmt"
)

// Claims type that uses the map[string]interface{} for JSON decoding
// This is the default claims type if you don't supply one
type MapClaims map[string]interface{}

// VerifyAudience Compares the aud claim ag
    
func (m MapClaims) VerifyAudience(cmp string, req bool) bool {
	var aud []string
	switch v := m["aud"].(type) {
	case string:
		aud = append(aud, v)
	case []string:
		aud = v
	case []interface{}:
		for _, a := range v {
			vs, ok := a.(string)
			if !ok {
				return false
			}
			aud = append(aud, vs)
		}
	}
	return verifyAud(aud, cmp, req)
}
