domain-driven-design - DDD - 在一个 BC 中更新用户密码，然后在另一个 BC 中通过电子邮件发送密码

Question

在我的域中，我有两个有界上下文，一个包含员工，另一个 BC 是电子邮件通信器，我的员工只有在获得批准后才会获得密码，因此此时会向他们发布密码。

这个密码是加密的，所以我想用新的加密密码联系包含员工的 BC，但还要在另一个 BC 中向他们发送一封电子邮件，其中包含一封包含他们的用户名和密码的欢迎电子邮件。

我考虑过为此使用事件，发送一个事件来更新 Employee 实体，另一个发送电子邮件。

这是最好的方法还是有人知道更好的方法？

提前致谢

Answer 1

Assuming the password is being changed by a POST request. * You will check if the current password is correct. * You will verify that the new password is valid and then encrypt it. * Will fire the PasswordWasChanged event * You will have the new password saved in an unencrypted variable, so just pass the new password to a service that will send the email to the user. (This service will be subscribed to listen to the PasswordWasChanged event but you will not need to use it.)

Comments: * It is not advisable to send the password by e-mail; * No way to save the decrypted password in the event.
