This article mainly explains "how to design the login module of Java". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to design the login module of Java.
Client side login module:
Make a preliminary test of the information entered in the Flying Q login information interface. If an error is found, all the input data is cleared so that the user can enter it again. If no errors are found, go to the main interface. The types of errors are:
1. Input data does not match
The account does not exist in the account database.
The password does not match the password of the corresponding account
2 input data cannot be empty
If (account is empty)
{
Please enter your account number and log in again.
}
Else if (account length is less than 6 or for 20)
{
Please enter the correct account number, which can be digits or Email address.
}
Else if (password is empty)
{
Please enter your password and log in again
}
Else
{
Notify the server that the account number is: xxx password: xxx request to log in
}
Server side:
Receive data and store it in loginpot
Determine whether the received password and the password in the server are the same. If the password is the same, the login is successful and a series of messages are sent (see below). If the password is different, the login failure is returned. If you log in with the same account, a kill instruction is sent to * * clients. After confirming that * clients are offline, the second client can log in.
