Beego模板用法-创建beeblog[通俗易懂]

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"] = "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>
    <h1 class="logo">Welcome to Beego</h1>
    <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>

➜ 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：
 <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：
