Using middleware

func main() {
  // Creates a router without any middleware by default
  router := gin.New()

  // Global middleware
  // Logger middleware will write the logs to gin.DefaultWriter even if you set with GIN_MODE=release.
  // By default gin.DefaultWriter = os.Stdout
  router.Use(gin.Logger())

  // Recovery middleware recovers from any panics and writes a 500 if there was one.
  router.Use(gin.Recovery())

  // Per route middleware, you can add as many as you desire.
  router.GET("/benchmark", MyBenchLogger(), benchEndpoint)

  // Authorization group
  // authorized := router.Group("/", AuthRequired())
  // exactly the same as:
  authorized := router.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
  router.Run(":8080")
