{"status":"error","err-code":"api-signature-not-valid","err-msg":"Signature not valid: Verification failure [校验失败]","data":null}

first i get accont information by client.AccountClient ,when i recieve the response, i use the same account client instance to get the account balance , this time the response is a error

{"status":"error","err-code":"api-signature-not-valid","err-msg":"Signature not valid: Verification failure [校验失败]","data":null}

but when i change the code like that
`
func (p *Signer) sign(payload string) string {
p.hash.Write([]byte(payload))
result := base64.StdEncoding.EncodeToString(p.hash.Sum(nil))

p.hash.Reset()
return result

}`
then there is no error，but i dont know whether it‘s correct
