使用中间件

func main() {
    // 创建一个不包含中间件的路由器
    r := gin.New()

    // 全局中间件
    // 使用 Logger 中间件
    r.Use(gin.Logger())

    // 使用 Recovery 中间件
    r.Use(gin.Recovery())

    // 路由添加中间件，可以添加任意多个
    r.GET("/benchmark", MyBenchLogger(), benchEndpoint)

    // 路由组中添加中间件
    // authorized := r.Group("/", AuthRequired())
    // exactly the same as:
    authorized := r.Group("/")
    // per group middleware! in this case we use the custom created
    // AuthRequired() middleware just in the "authorized" group.
    authorized.Use(AuthRequired())
    {
        authorized.POST("/login", loginEndpoint)
        authorized.POST("/submit", submitEndpoint)
        authorized.POST("/read", readEndpoint)

        // nested group
        testing := authorized.Group("testing")
        testing.GET("/analytics", analyticsEndpoint)
    }

    // Listen and serve on 0.0.0.0:8080
    r.Run(":8080")
