将文件上传到服务器的正确/正确方法是什么？

Question

What is the correct/proper way to upload files to a server? I'm only talking about small files such as images, text files, and excel/word files.

I know that I can upload images to the database using BLOB. But what about the others?

I have a table called "Ticket" which contains information such as date created, ticket number, caller, attachment , and etc.

I'm having problems on how to upload an attachment to a server.

Answer 1

The first option should be uploading the image to a file server and stored the file id or uuid in your ticket table, or a OneToMany table stores all attachments.

Always void using BLOB to store image binary in database. Database has this capability doesn't mean it's a good way to use it.

If you are working on a small project, you may not see the problem. If the concurrent is relatively high,

Imagine you store the files in the database, even all are just images, whenever you retrieve the tickets, the a-few-MB image will be in the memory. It's a waste of server memory.

If you are using some ORM to retrieve the list, which will be worst and your server can be easily OutOfMemory.

One more thing is that if your system has Web Application Firewall in front, it's also advisable to separate file upload with normal form submission.
