}

curl -H "Accept-Encoding: gzip,deflate" --compressed http://localhost:8080/raw

raw data

curl -H "Accept-Encoding: gzip,deflate" --compressed http://localhost:8080/json?pretty=y

Template Example

package main

import (
	"fmt"
	"github.com/hslam/handler/render"
	"github.com/hslam/mux"
	"log"
	"net/http"
)

type Student struct {
	Name    string
	Age     int32
	Address string
}

var studentTemplate = `
This is a Student Template:
Name: {{.Name}};
Age:{{.Age}};
Address: {{.Address}}.
`

var studentTemplateOne = `
<br>Name	-	{{.Name}}<br/>
<br>Age		-	{{.Age}}<br/>
<br>Address	-	{{.Address}}<br/>
`

var studentTemplateTwo = `
<html><body>
<table style='width:100%'>

	<tr><td align='center'>Age</td><td align='center'>{{.Age}}</td><tr>
	<tr><td align='center'>Address</td><td align='center'>{{.Address}}</td><tr>

</body></html>
`

func main() {
	r := render.NewRender()
	r.Parse(studentTemplate)
	r.ParseTemplate("1", studentTemplateOne)
	r.ParseTemplate("2", studentTemplateTwo)
	r.GzipAll().DeflateAll().Charset("utf-8")
	m := mux.New()
	m.HandleFunc("/template", func(w http.ResponseWriter, req *http.Request) {
		r.Execute(w, req, Student{"Mort Huang", 18, "Earth"}, http.StatusOK)
	}).All()
	m.HandleFunc("/template/:name", func(w http.ResponseWriter, req *http.Request) {
		params := m.Params(req)
		_, err := r.ExecuteTemplate(w, req, params["name"], Student{"Mort Huang", 18, "Earth"}, http.StatusOK)

		}
	}).All()
	log.Fatal(http.ListenAndServe(":8080", m))
}

curl -H "Accept-Encoding: gzip,deflate" --compressed http://localhost:8080/template

This is a Student Template:
Name: Meng Huang;
Age:18;
