1、创建beeblog项目

➜  go pwd
/Users/daixuan/qbox/go
➜  go bee new beeblog

drwxr-xr-x  10 daixuan  staff   320 Jul 29 17:20 beeblog

2、自定义数据结构

➜  beeblog vim /Users/daixuan/qbox/go/src/beeblog/controllers/default.go
package controllers

import (
    "github.com/astaxie/beego"
)

type MainController struct {
    beego.Controller
}

func (c *MainController) Get() {
    c.Data["Website"] = "beego.me"
    c.Data["Email"] = "astaxie@gmail.com"
    c.TplName = "index.tpl"
    c.Data["TrueCond"] = true
    c.Data["FalseCond"] = false
//添加一个结构
    type u struct{
        Name string
        Age int
        Sex string
    }
    user := &u{
        Name: "Joe",
        Age: 20,
        Sex: "Male",
    }
    c.Data["User"] = user
}

➜  beeblog vim /Users/daixuan/qbox/go/src/beeblog/views/index.tpl
<body>
  <header>
    <h2 class="logo">Welcome to Beego</h2>
    <div class="description">
      Beego is a simple & powerful Go web framework which is inspired by tornado and sinatra.
    </div>
  </header>
  <footer>
    <div class="author">
      Official website:
      <a href="http://{{.Website}}">{{.Website}}</a> /
      Contact me:
      <a class="email" href="mailto:{{.Email}}">{{.Email}}</a>
      <a class="email" href="mailto:{{.User}}">{{.User}}</a>
    </div>
  </footer>
  <div class="backdrop"></div>
  <div>
  {{if .TrueCond}}
    true condition
  {{end}}
  </div>

  <div>
  {{if .FalseCond}}
  {{else}}
    false condition.
  {{end}}
  </div>

  <div>
  {{.User.Name}}; {{.User.Age}}; {{.User.Sex}}
  </div>

  <script src="/static/js/reload.min.js"></script>
</body>

3、with end使用

注意:为了解决循环嵌套的问题,可以使用with end的方式

  <div>
  {{.User.Name}}; {{.User.Age}}; {{.User.Sex}}
  </div>
    这段代码可以修改为如下,效果相同:
  <div>
  {{with .User}}
  {{.Name}}; {{.Age}}; {{.Sex}}
  {{end}}
  </div>

访问:http://localhost:8080/

4、range使用

default.go 添加:
    nums := []int{1,2,3,4,5,6,7,8,9,0}
    c.Data["Nums"] = nums

index.tpl中添加:
 <div>
  {{.Nums}}
  </div>

  <div>
  {{range .Nums}}
  {{.}}
  {{end}}
  </div>

访问:http://localhost:8080/

5、自定义模板

default.go 添加:
    c.Data["TplVar"] = "hey guys"

index.tpl中添加:
  <div>
  {{$tplVar := .TplVar}}
  {{$tplVar}}
  </div>

访问:http://localhost:8080/

6、beego内置模板函数使用,以字符串转html模板函数

beego中写的任意html的代码,它都会自动编码

default.go 添加:
        c.Data.["Html"]="<div>hello beego</div>" 

index.tpl中添加:
  <div>
  {{.Html}}
  </div>

访问:http://localhost:8080/ 返回:<div>hello beego</div>,怎么以html格式显示呢?

    index.tpl中:
    <div>
  {{.Html}}
  </div>
    修改为如下即可:
      <div>
  {{str2html .Html}}
  </div>

再访问:http://localhost:8080/ 结果:
