The code below renders the initial page, which has a form in it. On submission of that form, I want to render a results page. The form submits and is handled, but all I see is a blank html document.
I don't want to only display an html page, but render it as some of the content will come from my golang code on form submission.I am trying to do this using templating ( from a template ) where designated lines in the <body></body> are the values of Golang variables.
I would greatly appreciate it if someone could help me figure out how to render a results page.
package main
import (
//"fmt"
"net/http"
"github.com/zenazn/goji"
"github.com/zenazn/goji/web"
"html/template"
"io/ioutil"
)
type Page struct {
Title string
Body []byte
}
func (p *Page) save() error{
filename := p.Title + ".txt"
return ioutil.WriteFile(filename, p.Body, 0600)
}
func loadPage(title string) (*Page, error){
filename := title + ".txt"
body, err := ioutil.ReadFile(filename)
if err != nil{
return nil, err
}
return &Page{Title: title, Body: body}, nil
}
func renderTemplate(w http.ResponseWriter, tmpl string, p *Page){
t, _ := template.ParseFiles("Projects/Go/src/web/site/" + tmpl + ".html")
t.Execute(w, p)
}
func editHandler(w http.ResponseWriter, r *http.Request){
title := r.URL.Path[len("/edit/"):]
p, err := loadPage(title)
if err != nil{
p = &Page{Title: title}
}
renderTemplate(w, "edit", p)
}
func viewHandler(w http.ResponseWriter, r *http.Request){
title := r.URL.Path[len("/ask"):]
p, _ := loadPage(title)
renderTemplate(w, "ask", p)
}
func response(c web.C, w http.ResponseWriter, r *http.Request){
//name := r.FormValue("name")
//fmt.Fprintf(w, "Hello, %s!", name)
http.HandleFunc("/ask", viewHandler)
http.HandleFunc("/edit/", editHandler)
//http.HandleFunc("/save", saveHandler)
http.ListenAndServe("8000", nil)
}
func serveSingle(filename string) func(w http.ResponseWriter, r *http.Request) {
return func(w http.ResponseWriter, r *http.Request) {
http.ServeFile(w, r, filename)
}
}
func main() {
goji.Get("/", serveSingle("Projects/Go/src/web/site/index.html"))
goji.Handle("/ask", response)
goji.Serve()
}
file structure:
root/Projects/Go/src/web/site/edit.html
root/Projects/Go/src/web/site/index.html
root/Projects/Go/src/web/site/view.html
index.html's body:
<form action="ask" method="get">
<input type="text" name="q" />
</form>
view.html's body:
<form action="ask" method="get">
<input type="text" name="q" />
</form>
<h1 class="abTitle">{{printf "%s" .Body}}</h1>
view.html and edit.html are the exact same.
