Compared with the prior art, the invention has the beneficial effects that:
1. after the user logs in the blockchain management system, the background service is restarted, the front-end operation is not influenced, an operator does not feel about the recovery of the user login session, the user login session is recovered from the mysql database, and the user login session failure caused by the restarting of the back-end service is avoided.
2. The server performance is improved, the user login session in the memory is checked preferentially, and the user login session in the mysql database is checked again, so that the database is prevented from being excessively stressed under the condition of high concurrency when the database is directly read each time.
3. The advantages of the user login session in the memory and the persistent user login session in the mysql database are combined, and the advantages of the user login session and the persistent user login session are integrated, so that high-quality service is provided for the user.
Drawings
FIG. 1 is a flow chart of a blockchain user session caching method that can improve server performance.
Detailed Description
Referring to fig. 1, in an embodiment of the present invention, a blockchain user session caching method capable of improving server performance includes the following steps:
step 1: invoking a blockchain management system login interface in a blockchain management system on a browser, and verifying login user information and a user login password;
step 2: after confirming that the login user information is background backup user information and the login password is correct, using sessionID as a credential to store the user information into a login session of a memory and a mysql database, and simultaneously feeding back the logged user information to a browser page for displaying the page and controlling the authority of a blockchain management system (the login process, namely the blockchain management system, creates the user session after confirming the user information and the password are correct, stores the session information into the memory and the mysql database, and returns the session ID to a browser operation page);
step 3: when a user wants to log in again due to improper operation or closing of a login page, acquiring a background sessionID from a browser page, acquiring a user login session from a memory by using sessionID credentials, and directly returning the login session to the browser page and passing login verification when the acquisition is successful;
step 4: when no user login session of sessionID exists in the memory, acquiring the user session from the mysql database by sessionID, if the acquisition is successful, recovering the login session in the memory, simultaneously returning the login session to a browser page, and passing login verification, if the acquisition of the user login session in the mysql database fails, failing the user login session or having no login information;
step 5: and setting a timing task for the MySQL database, and periodically executing to store the user information in the memory into MySQL.
Further, the sessionID is randomly generated according to a rule, for example, the beegosessionID_xxxx is used as a prefix, and a section of random number is added;
taking the session ID as a credential, user information and login information including login time, IP and expiration time are stored in a memory and mysql database.
Further, the browser page stores user information in the form of a cookie.
Further, the specific operation in step 5 is as follows: the user login session in the circulating memory is firstly obtained through the sessionID and the user information, after the login session is successfully obtained, whether the login session is out of date is checked, the validity period is refreshed in the validity period, and the user is directly returned after the validity period is exceeded.
Application example 1:
the user accesses the blockchain management system on the browser, and the current page of the blockchain management system is closed because other emergency matters need to be processed, and when the user returns to process the business of the blockchain management system, the user needs to log in again;
the invention solves the problem that the user can continue to operate only by opening the previous operation page without logging in again;
the implementation process comprises the following steps: the method comprises the steps of obtaining a session ID of a blockchain management system from a cookie in a browser, namely a session ID, attaching the session ID when the blockchain management system calls a back-end interface, and recovering a session through the session ID in background service of the blockchain management system.
