How to make url parameter values ​​change randomly

冲恋城

Hello everyone, I have another question about url.
For example, the url I requested is http://127.0.0.1:7777/app/test.jsp?sid=aed0000dfsdf
I want to find a way to process the sid in this url, so that it will be displayed differently in the IE address bar every time I request, that is, find an algorithm to make it always change randomly.
My most important purpose is that when someone pastes the obtained address directly in the url address bar, it cannot enter the system.
See if everyone has any good methods and suggestions, thank you

If it is impossible to enter the system,
I have to judge the session, it seems like this

Putting a mark in the session is the positive solution

Achieve your purpose and add a judgment to prevent external theft chain will not be over.

It doesn't need to deal with sid, just add login verification in your program.
Direct access to http://127.0.0.1:7777/app/test.jsp address is not verified whether you have logged in, if you do not log in, you can not directly enter the system.

1. Determine the login session.
2. The server time passed when logging in. Then add a custom or random encoding of the time when returning the url parameter, and then check it on the server side, for example, to judge the time difference.
3. Simply do not use the url parameter, and use a method such as session instead.

How to achieve it depends on your specific needs
