how to set Headers globally

[arpitjindal97]

There are few headers which I want to set on all of my endpoints.

ex: Access-Control-Allow-Origin

I know it can be set individually in the HandlerFunc but is there a way to set them globally ?

Yeh, you maybe use the http middleware and add it into the http router, for example,

func CORS() middleware.Middleware {
    return middleware.NewMiddleware("CORS", 123, func(h interface{}) interface {
        return http.HandlerFunc(func(w ResponseWriter, r *Request) {
            // TODO: Add some headers for the respsone
            w. Header().Set("Access-Control-Allow-Origin", "*")

            h.(http.Handler).ServeHTTP(w, r)
        })
    }
}

router.DefaultRouter.User(CORS())
router.DefaultRouter. RouteManager = ruler.DefaultRouter
ruler.DefaultRouter.Path("/path/to/1").GET(GetHandler)
ruler.DefaultRouter.Path("/path/to/2").POST(PostHandler)

Later, I will port the CORS and Gzip middlewares from ship.

I have added the http middlewares CORS and GZip. You can try v0.0.0-20220822143418-03eab6495b5c and I will tag it with v0.21.0 later. For example

// Use the middleware CORS and GZip.
router.DefaultRouter.Middlewares.Use(middlewares.CORS(123, nil), middlewares.GZip(456, nil))

// Use the rule router to manage the routes, which has been done by default.
// Here is only an example.
router.DefaultRouter.RouteManager = ruler.DefaultRouter

// Add the routes
ruler.DefaultRouter.Path("/path/to/1").GET(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
    // TODO:
}))

ruler.DefaultRouter.Path("/path/to/2").GETFunc(func(w http.ResponseWriter, r *http.Request) {
    // TODO:
})

ruler.DefaultRouter.Path("/path/to/3").GETContext(func(ctx *reqresp.Context) {
    // TODO:
})

ruler.DefaultRouter.Path("/path/to/4").GETContextWithError(func(ctx *reqresp.Context) error {
    // TODO:
    return nil
})
