重复登录怎么解决比如两台设备同时登录一个账号

Answer 1

There are two types of solutions. The first type is proactive. When your second client logs in, the first client is notified to log out. This requires a long connection between the client and the server.
The second type is passive. When the client logs in, it will obtain a token, and every subsequent operation will bring the token. The token will be updated each time it logs in. Therefore, when the second logs in, the token of the first login will be used. It will be invalid, log out at this time
