Middleware mainly refers to the interception of HTTP requests and some processing before the request arrives, such as data processing, permission control, authentication and so on.

R := gn.default (), Logger() and Recovery() are used globally for both middleware. If you don’t want to use either middleware, you can use r := gn.new ().

Middleware notation, which returns gin.HandlerFunc

func RequestInfos() gin.HandlerFunc {
  return func(Context *gin.Context){
  path := context.FullPath()
  method := context.Request.Method
  。。。。
  }
}

Added global middleware so RequestInfos() is executed first for every HTTP request

r.Use(requestInfos())

A single route is used, and RequestInfos() is executed when accessing the /benchmark route.

r.GET("/benchmark", requestInfos(), benchEndpoint)

Used in routing groups, middleware is used when accessing /test/ ABC

r := gin.Default()
v := r.Group("/test")
v.Use(requestInfos())
{
  v.POST("/abc", benchEndpoint)
}

How do I make the middleware execute after the request is executed

func RequestInfos() gin.HandlerFunc {
return func(context *gin.Context){
path := context.FullPath()
method := context.Request.Method
context.Next()
// after the request is executed
}
}
