使用Iris将HTTP转发到https

I'm trying to figure out how to get my golang app build with ìris`and the https://iris-go.com/v10/recipe#Secure57 library to achieve that. The application is hosted on GCE with a working ssl loadbalancer.

Here is my app:

s := secure.New(secure.Options{
        AllowedHosts:            []string{"mydomain.io"},
        SSLRedirect:             true,
        SSLTemporaryRedirect:    false,
        SSLHost:                 "",
        SSLProxyHeaders:         map[string]string{"X-Forwarded-Proto": "https"},
        STSSeconds:              315360000,
        STSIncludeSubdomains:    true,
        STSPreload:              true,
        ForceSTSHeader:          false,
        FrameDeny:               true,
        CustomFrameOptionsValue: "SAMEORIGIN",
        ContentTypeNosniff:      true,
        BrowserXSSFilter:        true,
        ContentSecurityPolicy:   "default-src *; style-src *; https://fonts.googleapis.com/css?family=Roboto+Mono:400,100,300italic,300,100italic,400italic,500,500italic,700,700italic&subset=latin,cyrillic",
        PublicKey:               ``,
        IsDevelopment:           false,
    })

    app := iris.New()
    app.Use(s.Serve)
    app.Use(recover.New())

When I type mydomain.io into the browser it won't forward it to https. What is missing?

there is no case to use the secure middleware here, you just want a second web server to redirect all :80 to :443, Iris has example for that as well, take a look at: https://github.com/kataras/iris/blob/master/_examples/http-listening/listen-tls/main.go#L22

// to start a new server listening at :80 and redirects
// to the secure address, then:
target, _ := url.Parse("https://127.0.1:443")
go host.NewProxy("127.0.0.1:80", target).ListenAndServe()

// start the server (HTTPS) on port 443, this is a blocking func,
// you can use iris.AutoTLS for letsencrypt if you want so.
app.Run(iris.TLS("127.0.0.1:443", "mycert.cert", "mykey.key"))

Have fun!
