首先奉上我的项目目录结构

   return t.Format("2006-01-02 15:04:05")
}

func Println(str1 string,str2 string) string{
   //fmt.Println(str1,str2)
   return str1+"---------"+str2
}

func main()  {
   r := gin.Default()

   //自定义模板函数 注意要办这个函数放在加载模板前
   r.SetFuncMap(template.FuncMap{
      "UnixToTime":UnixToTime,
      "prt":Println,
   })

   //加载模板放在配置路由上面
   r.LoadHTMLGlob("view/**/*")

   //配置加载静态文件目录
   r.Static("/static","./static")
   //前端
   r.GET("/", func(c *gin.Context) {
      c.HTML(http.StatusOK,"web/index.html",gin.H{
         "title":"首页sss",
         "sort" : 55,

   })

   r.Run()
}

web/index.html

{{ define "web/index.html" }}




    
    
    
    
    


    
    {{template "public/page_header.html" .}}

    
{{.title}}

    {{$t := .title}}

    
{{$t}}

    
    {{if ge .sort 60}}
        
及格
    {{else}}
        
不及格
    {{end}}

    
    {{range $key,$value := .list}}
        
key=>{{$key}}-----value=>{{$value}}
    {{end}}
    

    
    {{range $key,$value := .newlist}}
        
key=>{{$key}}-----value.Title=>{{$value.Title}}-------value.Content=>{{$value.Content}}
    {{end}}

    

    


    

    {{len .title}}

    
    
原样输出：{{.date}}
    
自定义函数输出：{{UnixToTime .date}}

    
自定义函数prt输出：{{prt .title .title}}

    


    {{template "public/page_footer.html" .}}





{{ end }}

public/page_footer.html

{{ define "public/page_footer.html" }}

    
    

        我是一个公共的底部
    

{{ end }}

public/page_header.html

{{ define "public/page_header.html" }}

    
    

        我是一个公共的标题
    

{{ end }}
