go revel 初探一

1.app/controllers/app.go控制器

package controllers

import "github.com/revel/revel"

type App struct {
    *revel.Controller
}

func (c App) Index() revel.Result {
    str := "传递一个变量到模版看看"
    return c.Render(str)
}

func (c App) Hello(Name string) revel.Result {
    c.Validation.Required(Name).Message("名字必填")
    if c.Validation.HasErrors() {
        c.Validation.Keep()
        c.FlashParams()
        return c.Redirect(App.Index)
    }
    return c.Render(Name)
}

2.app/views/App/Index.html模版文件（对应的controller为app.go文件的Index方法）

{{set . "title" "Home"}}
{{template "header.html" .}}

<header class="hero-unit" style="background-color:#A9F16C">
  <div class="container">
    <div class="row">
      <div class="hero-text">
        <h1>It works 啊哈哈哈! {{.str}}</h1>
        <p></p>
      </div>
    </div>
  </div>
</header>

{{range .errors}}
<p style="color:#c00">{{.Message}}</p>
{{end}}
<form action="/App/Hello" method="GET">
    <input type="text" name="Name" value="{{.flash.Name}}" />
    <input type="submit" value="提交" />
</form>
{{template "footer.html" .}}

app/views/App/Hello.html模版文件（对应的controller为app.go文件的Hello方法）

{{set . "title" "Home"}}
{{template "header.html" .}}

<h1>Hello {{.Name}}</h1>
<a href="/">返回</a>

{{template "footer.html" .}}

3.下面是header.html模版文件<!DOCTYPE html><html>

  <head>
    <title>{{.title}}</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <link rel="stylesheet" type="text/css" href="/public/css/bootstrap.css">
    <link rel="shortcut icon" type="image/png" href="/public/img/favicon.png">
    <script src="/public/js/jquery-1.9.1.min.js" type="text/javascript" charset="utf-8"></script>
    <!-- 往moreStyles和moreScripts中追加样式和js地址，在/public/目录下 -->
    {{append . "moreStyles" "ui-lightness/jquery-ui-1.7.2.custom.css"}}
    {{append . "moreScripts" "js/jquery-ui-1.7.2.custom.min.js"}}
    {{range .moreStyles}}
      <link rel="stylesheet" type="text/css" href="/public/{{.}}">
    {{end}}
    {{range .moreScripts}}
      <script src="/public/{{.}}" type="text/javascript" charset="utf-8"></script>
    {{end}}
  </head>
  <body>
