1. Introduction to the Gin framework:

Gin is a web framework written in Go language. It helps developers build high-performance, scalable web applications by providing a set of simple APIs.

The following are some basic functions of the Gin framework and their application scenarios:

1) Express Routing

Application Scenario: Routing is very important in web applications. Gin provides a quick and easy way to define routes, and routes can be easily mapped to handler functions. For example, we can define a route like this:

r.GET("/users/:id", func(c *gin.Context) {   id := c.Param("id")   // query user information according to id })

This route will match all requests starting with /users/ and pass the id parameter to the handler function. This allows us to easily handle a variety of different requests.

For a project, its routing will be more complicated, as follows:

Gin provides an easy and useful way to manage routes. We can group routes and then apply the same middleware to the entire group of routes. For example:

func main() { 
    r := gin.Default() 

    // use middleware 
    r.Use(Logger()) 

    // route grouping 
    v1 :=
