1. base64 & aes 加密
   base64.StdEncoding.DecodedLen
   returns the maximum length in bytes of the decoded data 导致密文长度异常解密失败

// base64编码
cipherTextBase64 := make([]byte, base64.StdEncoding.EncodedLen(len(cipherText)))
base64.StdEncoding.Encode(cipherTextBase64, cipherText)

// base64解码
cipherText := make([]byte, base64.StdEncoding.DecodedLen(len(cipherTextWithBase64)))
_, err := base64.StdEncoding.Decode(cipherText, cipherTextWithBase64)

// 如何解决

n, err := base64.StdEncoding.Decode(cipherText, cipherTextWithBase64)
cipherText[:n]
