Beego模板用法-创建beeblog

1、创建beeblog项目

➜  go pwd
/Users/daixuan/qbox/go
➜  go bee new 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"] = "[email protected]"
    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

  

    
Welcome to Beego
    

      Beego is a simple & powerful Go web framework which is inspired by tornado and sinatra.
    
  
  

    

      Official website:
      {{.Website}} /
      Contact me:
      {{.Email}}
      {{.User}}
    
  
  

  

  {{if .TrueCond}}
    true condition
  {{end}}
  

  

  {{if .FalseCond}}
  {{else}}
    false condition.
  {{end}}
  

  

  {{.User.Name}}; {{.User.Age}}; {{.User.Sex}}
  

  

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

  

  {{.User.Name}}; {{.User.Age}}; {{.User.Sex}}
  
    这段代码可以修改为如下，效果相同：
  

  {{with .User}}
  {{.Name}}; {{.Age}}; {{.Sex}}
  {{end}}
  

➜ beeblog bee run beeblog
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：
 

  {{.Nums}}
  

  

  {{range .Nums}}
  {{.}}
  {{end}}
  

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：
  

  {{$tplVar := .TplVar}}
  {{$tplVar}}
  

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"]="
hello beego
" 

index.tpl中添加：
  

  {{.Html}}
  

访问：http://localhost:8080/ 返回：

hello beego

，怎么以html格式显示呢？

    index.tpl中：
    

  {{.Html}}
  
    修改为如下即可：
      

  {{str2html .Html}}
  

再访问：http://localhost:8080/ 结果：
