Gin-Gonic with hero example

[borowiak]

Hi everyone, I wrote code for Hero template system example and
I merged it with Gin framework, I didn't see any like this in documentation, I think this can be useful for someone else.
I based my code en 2 basic examples.
I don't sure where post this, so I opened a issues
please feel free to write any suggestion.

@gin-gonic

`package main

import (
"bytes"
"fmt"
"ginapp/template"
"io"
"net/http"

"github.com/gin-gonic/gin"
)

func main() {
router := gin.Default()
router.GET("/someDataFromReader", func(c *gin.Context) {
var buffer bytes.Buffer
var reader io.Reader
contentType := "text/html , utf8"

extraHeaders := map[string]string{
	"accept-ranges": "bytes",
}

var userList = []string{
	"Alice",
	"Bob",
	"Tom",
}

template.UserList(userList, &buffer)

nRead := int64(len(buffer.Bytes()))
reader = bytes.NewReader(buffer.Bytes())

fmt.Println(nRead)

c.DataFromReader(http.StatusOK, nRead, contentType, reader, extraHeaders)

})
router.Run(":8080")
}
`

This works for me.

func (c CoreController) Pages(c *gin.Context) {
	var userList = []string{
		"Alice",
		"Bob",
		"Tom",
	}

	buffer := new(bytes.Buffer)
	views.UserList(userList, buffer)

	c.Data(c.HttpStatus, "text/html; charset=utf-8", buffer.Bytes())
}
