在python2中创建AWS SES SMTP凭证

Question

我正在从我的iam accesskey和secretkey创建SES SMTP凭据。我参考了这个文档来创建SES SMTP凭据

但是代码为python2和python3生成不同的SES SMTP凭据，但python3密钥是有效的。在使用python2执行脚本时，我如何获得相同的键下面是我的脚本，它返回accesskey和SES SMTP信用。我从秘密管理器

获得Iam访问密钥和秘密密钥

signature_and_version = bytes([VERSION]) + signature
smtp_password = base64.b64encode(signature_and_version)
print(smtp_password)
return smtp_password.decode('utf-8')
def get_keys():
accesskey, secretkey = get_secretmanager() 
mailsecret = calculate_key(secretkey, "us-west-2")
return accesskey, mailsecret
print(get_keys())

任何帮助都是非常感激的，谢谢你

经过大量的调试，我发现bytes([VERSION])在python3和python2中都不工作，这就是为什么它为2和3返回2个不同的值我的简单修复是将十六进制0x04的字节值硬编码为b'x04'

signature_and_version = b'x04' + signature

确保以字符串return accesskey, str(mailsecret)返回值，因为在python2中它以unicode返回。
