An example of an AI chatbot conversation about Gin middleware in web development.
What is Gin middleware and how does it work?
Gin middleware is a function that can intercept requests and responses in a Gin web application. It allows you to execute code before or after the main handler.
Can you give me an example of a middleware function?
Sure! A simple logging middleware could look like this: func Logger() gin.HandlerFunc { return func(c *gin.Context) { log.Println(c.Request.Method, c.Request.URL) c.Next() } }.
How do I apply this middleware to my routes?
You can apply it globally using r.Use(Logger()) or to specific routes like r.GET("/path", Logger(), handlerFunc).
What are some common use cases for middleware?
Common use cases include logging, authentication, error handling, and request validation.
