After modifying the domain name.Attachments such as pictures are no longer displayed. Please ask why it is a security problem or for what purpose not to save these materials in a relative path?Novice doesn't understand
also.I searched the Internet for a solution to this problem.Most of them modify the database
I also found this problem. This is because the attachment address has an IP address. I recently used the 80x86 image docker version and found no such problem
