Golang框架Gin入门实战–(3)HTML模板渲染及模板语法(上)
package main
import "github.com/gin-gonic/gin"
type Article struct {
Title string
Content string
}
func main() {
r := gin.Default()
//加载模板
r.LoadHTMLGlob("templates/**/*")
//前台
r.GET("/", func(c *gin.Context) {
c.HTML(200, "default/index.html", gin.H{
"title": "首页",
"msg": "我是msg",
"score": 89,
"hobby": []string{"吃饭", "睡觉", "写代码"},
"newsList": []interface{}{
&Article{
Title: "新闻标题111",
Content: "新闻详情111",
},
&Article{
Title: "新闻标题222",
Content: "新闻详情222",
},
},
"testSlice": []string{},
"news": &Article{
Title: "新闻标题",
Content: "新闻内容",
},
})
})
r.GET("/news", func(c *gin.Context) {
news := &Article{
Title: "新闻标题",
Content: "新闻详情",
}
c.HTML(200, "default/news.html", gin.H{
"title": "新闻页面",
"news": news,
})
})
//后台
r.GET("/admin", func(c *gin.Context) {
c.HTML(200, "admin/index.html", gin.H{
"title": "后台首页",
})
})
r.GET("/admin/news", func(c *gin.Context) {
c.HTML(200, "admin/news.html", gin.H{
"title": "新闻页面",
})
})
r.Run()
}在demo目录下创建templates文件夹
再在templates文件夹创建两个admin、default文件夹
在这里插入图片描述
templates/admin/index.html
{{define "admin/index.html"}}

<!--相当于给模板定义一个名称 define-end成对出现-->
{{define "default/index.html"}}

{{$t := .title}}
<!-- 定义变量 -->

<!-- 条件判断 -->
{{if ge .score 60}}

<p>不及格</p>
{{end}}
{{if gt .score 90}}
<p>优秀</p>
{{else if gt .score 80}}
<p>良好</p>
{{else if gt .score 60}}

<!-- 循环遍历数据 -->
