Functions

func IsTokenExpiredError

func IsTokenExpiredError(err error) bool

func Sign

func Sign(key []byte, method jwt.SigningMethod, claims jwt.MapClaims, options ...jwt.TokenOption) (string, error)

Sign 生成JWT字符串.

@param key 密钥（secret） @param method e.g. jwt.SigningMethodHS256 || jwt.SigningMethodHS384 || jwt.SigningMethodHS512

func SignWithCaesar

func SignWithCaesar(caesarShift int, key []byte, method jwt.SigningMethod, claims jwt.MapClaims, options ...jwt.TokenOption) (cipherText string, err error)

func Verify

func Verify(tokenString string, keyFunc jwt.Keyfunc, options ...jwt.ParserOption) (jwt.MapClaims, error)

Verify 验证JWT字符串.

PS: 如果 token 过期（根据"exp"，有的话），会返回 error（可以通过 IsTokenExpiredError 判断）.

@param keyFunc 此函数的第一个返回值为密钥(secret)

e.g.
func(token *jwt.Token) (interface{}, error) {
	// Don't forget to validate the alg is what you expect:
	if _, ok := token.Method.(*jwt.SigningMethodHMAC); !ok {
		return nil, fmt.Errorf("unexpected signing method: %v", token.Header["alg"])
	}

	// hmacSampleSecret is a []byte containing your secret, e.g. []byte("my_secret_key")
	return key, nil
}

func VerifyWithCaesar

func VerifyWithCaesar(caesarShift int, cipherText string, keyFunc jwt.Keyfunc, options ...jwt.ParserOption) (jwt.MapClaims, error)
