不使用gocli直接写

package main

import (
    "github.com/gogf/gf/frame/g"
    "github.com/gogf/gf/net/ghttp"
)

func main() {
    s := g.Server()

    // 使用原生的模板引擎gview模块来实现模板管理
    v := g.View()
    // 设置解析变量分隔符
    v.SetDelimiters("[[", "]]")
    // 添加当前模板引擎对象的模板目录路径
    v.AddPath("./templates")

    // 返回html文本
    s.BindHandler("/", func(r *ghttp.Request) {
        r.Response.Write("<h1>hello</h1>")
    })

    // 返回JSON
    s.BindHandler("/json", func(r *ghttp.Request) {
        var data = struct{
            Name string `json:"name"`
            Age int `json:"age"`
        }{
            "admin",
            23,
        }
        r.Response.WriteJson(data)
    })

    // 返回XML
    s.BindHandler("/xml", func(r *ghttp.Request) {
        var data = struct{
            Name string `json:"name"`
            Age int `json:"age"`
        }{
            "admin",
            23,
        }
        r.Response.WriteXml(data)
    })

    // 返回HTML
    s.BindHandler("/html", func(r *ghttp.Request) {
        r.Response.WriteTpl("index.html")
    })

    s.Run()
}
