4. Router

1) 常规路由
  • 支持GET\POST\HEAD\OPTIONS\PUT\PATCH\DELETE 这几类请求方法
  • 支持HiJack\WebSocket\ServerFile三类特殊应用
  • 支持Any注册方式，默认兼容GET\POST\HEAD\OPTIONS\PUT\PATCH\DELETE方式
  • 支持通过配置开启默认添加HEAD方式
  • 支持注册Handler，以启用配置化
  • 支持检查请求与指定路由是否匹配
1、Router.GET(path string, handle HttpHandle)
2、Router.POST(path string, handle HttpHandle)
3、Router.HEAD(path string, handle HttpHandle)
4、Router.OPTIONS(path string, handle HttpHandle)
5、Router.PUT(path string, handle HttpHandle)
6、Router.PATCH(path string, handle HttpHandle)
7、Router.DELETE(path string, handle HttpHandle)
8、Router.HiJack(path string, handle HttpHandle)
9、Router.WebSocket(path string, handle HttpHandle)
10、Router.Any(path string, handle HttpHandle)
11、Router.RegisterRoute(routeMethod string, path string, handle HttpHandle)
12、Router.RegisterHandler(name string, handler HttpHandle)
13、Router.GetHandler(name string) (HttpHandle, bool)
14、Router.MatchPath(ctx Context, routePath string) bool

接受两个参数，一个是URI路径，另一个是 HttpHandle 类型，设定匹配到该路径时执行的方法；

2) static router

静态路由语法就是没有任何参数变量，pattern是一个固定的字符串。

package main

import (
    "github.com/devfeel/dotweb"
)

func main() {
    dotapp := dotweb.New()
    dotapp.HttpServer.GET("/hello", func(ctx *dotweb.HttpContext) {
        ctx.WriteString("hello world!")
    })
    dotapp.StartServer(80)
}

test： curl http://127.0.0.1/hello

3) parameter router

参数路由以冒号 : 后面跟一个字符串作为参数名称，可以通过 HttpContext的 GetRouterName 方法获取路由参数的值。

package main

import (
    "github.com/devfeel/dotweb"
)

func main() {
    dotapp := dotweb.New()
    dotapp.HttpServer.GET("/hello/:name", func(ctx dotweb.Context) error{
        _, err := ctx.WriteString("hello " + ctx.GetRouterName("name"))
        return err
    })
    dotapp.HttpServer.GET("/news/:category/:newsid", func(ctx dotweb.Context) error{
    	category := ctx.GetRouterName("category")
	    newsid := ctx.GetRouterName("newsid")
        _, err := ctx.WriteString("news info: category=" + category + " newsid=" + newsid)
        return err
    })
    dotapp.StartServer(80)
}

test：
curl http://127.0.0.1/hello/devfeel
curl http://127.0.0.1/hello/category1/1

4) group router
    g := server.Group("/user")
	g.GET("/", Index)
	g.GET("/profile", Profile)

test：
curl http://127.0.0.1/user
curl http://127.0.0.1/user/profile

5. Binder

  • HttpContext.Bind(interface{})
  • Support data from json、xml、Form
type UserInfo struct {
		UserName string `form:"user"`
		Sex      int    `form:"sex"`
}

func(ctx *dotweb.HttpContext) TestBind{
        user := new(UserInfo)
        if err := ctx.Bind(user); err != nil {
        	 ctx.WriteString("err => " + err.Error())
        }else{
             ctx.WriteString("TestBind " + fmt.Sprint(user))
        }
}

6. Middleware

Middleware
  • 支持粒度：App、Group、RouterNode
  • DotWeb.Use(m ...Middleware)
  • Group.Use(m ...Middleware)
  • RouterNode.Use(m ...Middleware)
  • 启用顺序：App -> Group -> RouterNode，同级别下按Use的引入顺序执行
  • Middleware List
  • JWT - example
  • AccessLog - example
  • CROS - example
  • Gzip
  • BasicAuth
  • Recover
  • HeaderOverride
app.Use(NewAccessFmtLog("app"))

func InitRoute(server *dotweb.HttpServer) {
	server.GET("/", Index)
	server.GET("/use", Index).Use(NewAccessFmtLog("Router-use"))

	g := server.Group("/group").Use(NewAccessFmtLog("group"))
	g.GET("/", Index)
	g.GET("/use", Index).Use(NewAccessFmtLog("group-use"))
}

type AccessFmtLog struct {
	dotweb.BaseMiddlware
	Index string
}

func (m *AccessFmtLog) Handle(ctx dotweb.Context) error {
	fmt.Println(time.Now(), "[AccessFmtLog ", m.Index, "] begin request -> ", ctx.Request.RequestURI)
	err := m.Next(ctx)
	fmt.Println(time.Now(), "[AccessFmtLog ", m.Index, "] finish request ", err, " -> ", ctx.Request.RequestURI)
	return err
}

func NewAccessFmtLog(index string) *AccessFmtLog {
	return &AccessFmtLog{Index: index}
}

7. Server Config

HttpServer：
  • HttpServer.EnabledSession 设置是否开启Session支持，目前支持runtime、redis两种模式，默认不开启
  • HttpServer.EnabledGzip 设置是否开启Gzip支持，默认不开启
  • HttpServer.EnabledListDir 设置是否启用目录浏览，仅对Router.ServerFile有效，若设置该项，则可以浏览目录文件，默认不开启
  • HttpServer.EnabledAutoHEAD 设置是否自动启用Head路由，若设置该项，则会为除Websocket\HEAD外所有路由方式默认添加HEAD路由，默认不开启
Run Mode
  • 新增development、production模式
  • 默认development，通过DotWeb.SetDevelopmentMode\DotWeb.SetProductionMode开启相关模式
  • 若设置development模式，未处理异常会输出异常详细信息
  • 未来会拓展更多运行模式的配置

8. Exception

500 error
  • Default: 当发生未处理异常时，会根据RunMode向页面输出默认错误信息或者具体异常信息，并返回 500 错误头
  • User-defined: 通过DotServer.SetExceptionHandle(handler *ExceptionHandle)实现自定义异常处理逻辑
type ExceptionHandle func(Context, error)
404 error
  • Default: 当发生404异常时，会默认使用http.NotFound处理
  • User-defined: 通过DotWeb.SetNotFoundHandle(handler NotFoundHandle)实现自定义404处理逻辑
type NotFoundHandle  func(http.ResponseWriter, *http.Request)

9. Session

Support store in runtime、redis
  • default is disabled, you must use app.HttpServer.SetEnabledSession(true) to enabled it
  • runtime:store in runtime memory
  • redis:store in redis,redis-key named with dotweb:session:xxxxxxxxxxxx
//enabled session
dotapp.HttpServer.SetEnabledSession(true)
//use runtime mode
dotapp.HttpServer.SetSessionConfig(session.NewDefaultRuntimeConfig())
//use redis mode
dotapp.HttpServer.SetSessionConfig(session.NewDefaultRedisConfig("127.0.0.1:6379"))
//use session with DotWeb.Context
ctx.Session().Set(key, value)
