Using middleware

  1. func main() {
  2.     // Creates a router without any middleware by default
  3.     r := gin.New()
  5.     // Global middleware
  6.     // Logger middleware will write the logs to gin.DefaultWriter even if you set with GIN_MODE=release.
  7.     // By default gin.DefaultWriter = os.Stdout
  8.     r.Use(gin.Logger())
  10.     // Recovery middleware recovers from any panics and writes a 500 if there was one.
  11.     r.Use(gin.Recovery())
  13.     // Per route middleware, you can add as many as you desire.
  14.     r.GET("/benchmark", MyBenchLogger(), benchEndpoint)
  16.     // Authorization group
  17.     // authorized := r.Group("/", AuthRequired())
  18.     // exactly the same as:
  19.     authorized := r.Group("/")
  20.     // per group middleware! in this case we use the custom created
  21.     // AuthRequired() middleware just in the "authorized" group.
  22.     authorized.Use(AuthRequired())
  23.     {
  24.         authorized.POST("/login", loginEndpoint)
  25.         authorized.POST("/submit", submitEndpoint)
  26.         authorized.POST("/read", readEndpoint)
  28.         // nested group
  29.         testing := authorized.Group("testing")
  30.         testing.GET("/analytics", analyticsEndpoint)
  31.     }
  33.     // Listen and serve on 0.0.0.0:8080
  34.     r.Run(":8080")
  35. }
