[Ginny series] Go-based web background development to implement a simple user system

Implement a simple user system

Now that the code is written, you will find that we already have a short program (only 60 lines!), but can implement a basic background interface and interact with the database! This is really exciting! Then keep this enthusiasm, let's implement a basic user system!

Before that, we have to tidy up our code (although it only has 60 lines):

3.1 Start to organize our code structure

Our main.goyears now includes several parts: a statement routing, establish a database connection, as well as a handler, but these things are put together will feel a bit chaotic. So let's build a good catalog!

The rebuilt directory structure is as follows:

├── handler
│   ├── handler.go
│   ├── login
│   └── register
│       └── register.go
├── model
│   ├── init.go
│   └── user.go
├── router
│   └── router.go
└── main.go

Then we explain the role of each part:

• handler
