This verification code is quite magical. It can be displayed and used normally if you follow the tutorial. If you change the directory and put the downloaded source code, it will not be displayed if it has not been modified.
Also put it in the secondary directory Afterwards, the verification code can be displayed normally when opening the page. Once refreshed, it will no longer be displayed. If the username or password is filled in incorrectly, the verification code will not be displayed after refilling. It will prompt that the verification code is incorrect. How do I debug this?
