gweb

golang web 轻框架

最轻量的包装,灵活极易扩展,采用流行的MVC框架思想。

支持特性:

  • 子路径独立拦截器和控制器
  • 添加子控制器
  • 支持RESTful,OPTIONS,GET,HEAD,POST,PUT,DELETE,TRACE,CONNECT
  • 支持 {id}/path 路径映射
  • 内置返回类型有:ViewResult,HTMLResult,JsonResult,TextResult,RedirectToUrlResult,ImageResult,ImageBytesResult
  • 内置模板函数,除了golang的函数,还增加了IncludeHTML,Split,FromJSONToMap,FromJSONToArray,CipherDecrypter,CipherEncrypter,Int2String,Uint2String,Float2String,ToJSON

安装:

go get github.com/nbvghost/gweb

配制文件说明:

默认配制文件信息: {"ViewDir":"view","ResourcesDir":"resources","DefaultPage":"index","JsonDataPath":"data.json","HttpPort":":80","HttpsPort":":443","ViewSuffix":".html","ViewActionMapping":true,"TLSCertFile":"","TLSKeyFile":""}]

  • ViewDir:视图文件夹名
  • ResourcesDir:资源文件夹名
  • DefaultPage:默认文件名
  • JsonDataPath:json 数据文件,这个文件在所有视图文件中可以读取到,可用于程序业务配制信息一块。
  • HttpPort:http 端口
  • HttpsPort:https 端口
  • ViewSuffix:视图文件后缀
  • TLSCertFile,TLSKeyFile: https 证书文件

使用例子:

package main

import (
	"github.com/nbvghost/gweb"
	"github.com/nbvghost/gweb/conf"
	"net/http"
	"net/url"
	"time"
)

//拦截器
type InterceptorManager struct {
}

//拦截器 方法,如果 允许登陆 返回true
func (this InterceptorManager) Execute(context *gweb.Context) (bool, gweb.Result) {
	if context.Session.Attributes.Get("admin") == nil { //判断当前 session 信息
		redirect := "" // 跳转地址
		if len(context.Request.URL.Query().Encode()) == 0 {
			redirect = context.Request.URL.Path
		} else {
			redirect = context.Request.URL.Path + "?" + context.Request.URL.Query().Encode()
		}
		//http.Redirect(Response, Request, "/account/login?redirect="+url.QueryEscape(redirect), http.StatusFound)
		return false, &gweb.RedirectToUrlResult{Url: "/account/login?redirect=" + url.QueryEscape(redirect)}
	} else {
		return true, nil
	}
}

type User struct {
	Name string
	Age  int
}

//index路由控制器
type IndexController struct {
	gweb.BaseController
}

func (c *IndexController) Apply() {
	c.Interceptors.Add(&InterceptorManager{}) //拦截器


	// 添加index地址映射
	//访问路径示例:http://127.0.0.1:80/index
	c.AddHandler(gweb.ALLMethod("index", func(context *gweb.Context) gweb.Result {
		return &gweb.HTMLResult{}
	}))

	//访问子路径示例:http://127.0.0.1:80/wx/
	wx := &WxController{}
	wx.Interceptors = c.Interceptors //使用 父级 拦截器
	c.AddSubController("/wx/", wx)   // 添加子控制器,相关的路由定义在 WxController.Apply() 里

}

//account路由控制器
type AccountController struct {
	gweb.BaseController
}

func (c *AccountController) Apply() {

	//访问路径示例:http://127.0.0.1:80/account/login
	c.AddHandler(gweb.GETMethod("login", func(context *gweb.Context) gweb.Result {

		user := &User{Name: "user name", Age: 12}

		context.Session.Attributes.Put("admin", user)

		redirect := context.Request.URL.Query().Get("redirect")

		return &gweb.RedirectToUrlResult{Url: redirect}
	}))

}

// /wx 路由控制器
type WxController struct {
	gweb.BaseController
}

func (c *WxController) Apply() {

	//访问路径示例:http://127.0.0.1:80/wx/44545/path
	c.AddHandler(gweb.GETMethod("{id}/path", func(context *gweb.Context) gweb.Result {

		user := context.Session.Attributes.Get("admin").(*User)

		return &gweb.HTMLResult{Name: "wx/path", Params: map[string]interface{}{"User": user, "Id": context.PathParams}}
	}))
	//访问路径示例:http://127.0.0.1:80/wx/info
	c.AddHandler(gweb.GETMethod("info", func(context *gweb.Context) gweb.Result {

		user := context.Session.Attributes.Get("admin").(*User)

		return &gweb.HTMLResult{Params: map[string]interface{}{"User": user}}
	}))

}
func main() {

	//初始化控制器,拦截 / 路径
	index := &IndexController{}
	index.NewController("/", index)

	//初始化控制器,拦截 /account 路径
	account := &AccountController{}
	account.NewController("/account", account)

	httpServer := &http.Server{
		Addr:         conf.Config.HttpPort,
		Handler:      http.DefaultServeMux,
		ReadTimeout:  60 * time.Second,
		WriteTimeout: 60 * time.Second,
		//MaxHeaderBytes: 1 << 20,
	}

	//启动web服务器
	gweb.StartServer(http.DefaultServeMux,httpServer, nil)

	//也可用,内置函数,gweb只是简单的做一个封装的
	//err := http.ListenAndServe(conf.Config.HttpPort, nil)
	//log.Println(err)
}
