Overview ¶
If you want to use it as middleware for the entire controller you can use its router which is just a sub router to add it as you normally do with standard API:
I'll show you 4 different methods for adding a middleware into an mvc application, all of those 4 do exactly the same thing, select what you prefer, I prefer the last code-snippet when I need the middleware to be registered somewhere else as well, otherwise I am going with the first one:
```go // 1
mvc.Configure(app.Party("/user"), func(m *mvc.Application) { m.Router.Use(cache.Handler(10*time.Second)) })
```
```go // 2 // same: userRouter := app.Party("/user") userRouter.Use(cache.Handler(10*time.Second)) mvc.Configure(userRouter, ...) ```
```go // 3 // same: userRouter := app.Party("/user", cache.Handler(10*time.Second)) mvc.Configure(userRouter, ...) ```
```go // 4 // same:
app.PartyFunc("/user", func(r iris.Party){ r.Use(cache.Handler(10*time.Second)) mvc.Configure(r, ...) })
```
If you want to use a middleware for a single route, for a single controller's method that is already registered by the engine and not by custom `Handle` (which you can add the middleware there on the last parameter) and it's not depend on the `Next Handler` to do its job then you just call it on the method:
```go var myMiddleware := myMiddleware.New(...) // this should return an iris/context.Handler
type UserController struct{}
func (c *UserController) GetSomething(ctx iris.Context) { // ctx.Proceed checks if myMiddleware called `ctx.Next()` // inside it and returns true if so, otherwise false. nextCalled := ctx.Proceed(myMiddleware) if !nextCalled { return } // else do the job here, it's allowed }
```
And last, if you want to add a middleware on a specific method and it depends on the next and the whole chain then you have to do it using the `AfterActivation` like the example below:
