Connect to the database
Get the value passed by the post method of modifying the page, and the time is obtained by timestamp
Execute the modification statement. If it succeeds, it will prompt that the modification is successful and jump to the background article management page. If it fails, it will prompt that the article modification failed and jump to the article management page.
