golang Iris – function to view
// Default template funcs are:
//
// - {{ urlpath "myNamedRoute" "pathParameter_ifNeeded" }}
// - {{ render "header.html" }}
// and partial relative path to current page:
// - {{ render_r "header.html" }}
// - {{ yield }}
// - {{ current }}
// Register a custom template func:
tmpl.AddFunc("greet", func(s string) string {
return "Greetings " + s + "!"
})golang iris return directly template html

type HelloController struct{}
var helloView = mvc.View{
Name: "hello/index.html",
Data: map[string]interface{}{
"Title": "Hello Page",
//"MyMessage": "Welcome to my awesome website",
},
}
func (c *HelloController) Get() mvc.Result {
return helloView
}Golang Iris – ctx.ViewData(key,value) alternative for HTML output
@krokite I don’t know if this is the best way, but this is how I do it and it works:
ctx.ViewData("content", template.HTML("<p>This is HTML content.</p><br><h3>Another String</h3>"))
or create a tmpl func:
tmpl := iris.HTML(...)
tmpl.AddFunc("html", func(text string) template.HTML {
return template.HTML(text)
})
ctx.ViewData("text", "<p>This is HTML content.</p><br><h3>Another String</h3>")
{{html .text}}
Don’t forget to import the "html/template" package.

}

println("After the mainHandler")
}
func mainHandler(ctx iris.Context) {
println("Inside mainHandler")
// take the info from the "before" handler.
info := ctx.Values().GetString("info")
// write something to the client as a response.
ctx.HTML("<h1>Response</h1>")
ctx.HTML("<br/> Info: " + info)
ctx.Next() // execute the "after".
