rzrbld/middleware

Community Middleware for the Iris web framework.

This repository provides a way to share any minor handlers for iris web framework. You can view the built'n supported handlers by pressing here.

Installation

Install a middleware, take for example the cors one.

$ go get github.com/iris-contrib/middleware/cors

import as

import "github.com/iris-contrib/middleware/cors"

// [...]

go build

Middleware is just a chain handlers which can be executed before or after the main handler, can transfer data between handlers and communicate with third-party libraries, they are just functions.

Middleware	Description	Example
jwt	Middleware checks for a JWT on the Authorization header on incoming requests and decodes it.	jwt/_example
cors	HTTP Access Control.	cors/_example
secure	Middleware that implements a few quick security wins.	secure/_example
tollbooth	Generic middleware to rate-limit HTTP requests.	tollbooth/_examples/limit-handler
cloudwatch	AWS cloudwatch metrics middleware.	cloudwatch/_example
new relic	Official New Relic Go Agent.	newrelic/_example
prometheus	Easily create metrics endpoint for the prometheus instrumentation tool	prometheus/_example
casbin	An authorization library that supports access control models like ACL, RBAC, ABAC	casbin/_examples
raven	Sentry client in Go	raven/_example
csrf	Cross-Site Request Forgery Protection	csrf/_example

How can I register middleware?

To a single route

app := iris.New()
app.Get("/mypath", myMiddleware1, myMiddleware2, func(ctx iris.Context){}, func(ctx iris.Context){}, myMiddleware5,myMainHandlerLast)

To a party of routes or subdomain

p := app.Party("/sellers", authMiddleware, logMiddleware)

OR

p := app.Party("/customers")
p.Use(logMiddleware)

To all routes

app.Use(func(ctx iris.Context){}, myMiddleware2)

To global, all routes, parties and subdomains

app.UseGlobal(func(ctx iris.Context){}, myMiddleware2)

Can I use standard net/http handler with iris?

Yes you can, just pass the Handler inside the iris.FromStd in order to be converted into iris.Handler and register it as you saw before.

Convert handler which has the form of http.Handler/HandlerFunc

package main

import (
    "github.com/kataras/iris/v12"
)

func main() {
    app := iris.New()

    sillyHTTPHandler := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request){
            println(r.RequestURI)
    })

    sillyConvertedToIon := iris.FromStd(sillyHTTPHandler)
    // FromStd can take (http.ResponseWriter, *http.Request, next http.Handler) too!
    app.Use(sillyConvertedToIon)

    app.Run(iris.Addr(":8080"))
}
