java restful路由算法,go-restful实现restful接口

之前一直使用使用beego和原生的http来实现http接口，其中beego在路由上也提供了灵活的注册方式，但是最近在看kubernetes源码的时候发现内部使用的是

以下例子作为初步尝试，后续在项目在逐步使用

package main

import (

"github.com/emicklei/go-restful"

"github.com/emicklei/go-restful-swagger12"

"io"

"log"

"net/http"

)

func main(){

wsContainer := restful.NewContainer()

// 跨域过滤器

cors := restful.CrossOriginResourceSharing{

ExposeHeaders: []string{"X-My-Header"},

AllowedHeaders: []string{"Content-Type", "Accept"},

AllowedMethods: []string{"GET", "POST"},

CookiesAllowed: false,

Container: wsContainer}

wsContainer.Filter(cors.Filter)

// Add container filter to respond to OPTIONS

wsContainer.Filter(wsContainer.OPTIONSFilter)

config := swagger.Config{

WebServices: restful.DefaultContainer.RegisteredWebServices(), // you control what services are visible

WebServicesUrl: "http://localhost:8080",

ApiPath: "/apidocs.json",

ApiVersion: "V1.0",

// Optionally, specify where the UI is located

SwaggerPath: "/apidocs/",

SwaggerFilePath: "D:/gowork/src/doublegao/experiment/restful/dist"}

swagger.RegisterSwaggerService(config, wsContainer)

//swagger.InstallSwaggerService(config)

u := UserResource{}

u.RegisterTo(wsContainer)

log.Print("start listening on localhost:8080")

server := &http.Server{Addr: ":8080", Handler: wsContainer}

defer server.Close()

log.Fatal(server.ListenAndServe())

}

type UserResource struct{}

func (u UserResource) RegisterTo(container *restful.Container) {

ws := new(restful.WebService)

//设置匹配的schema和路径

ws.Path("/user").Consumes("*/*").Produces("*/*")

//设置不同method对应的方法，参数以及参数描述和类型

//参数:分为路径上的参数,query层面的参数,Header中的参数

ws.Route(ws.GET("/{id}").

To(u.result).

Doc("方法描述：获取用户").

Param(ws.PathParameter("id", "参数描述:用户ID").DataType("string")).

Param(ws.QueryParameter("name", "用户名称").DataType("string")).

Param(ws.HeaderParameter("token", "访问令牌").DataType("string")).

Do(returns200, returns500))

ws.Route(ws.POST("").To(u.result))

ws.Route(ws.PUT("/{id}").To(u.result))

ws.Route(ws.DELETE("/{id}").To(u.result))

container.Add(ws)

}

func (UserResource) SwaggerDoc() map[string]string {

return map[string]string{

"": "Address doc",//空表示结构本省的描述

"country": "Country doc",

"postcode": "PostCode doc",

}

}

func (u UserResource) result(request *restful.Request, response *restful.Response) {

io.WriteString(response.ResponseWriter, "this would be a normal response")

}

func returns200(b *restful.RouteBuilder) {

b.Returns(http.StatusOK, "OK", "success")

}

func returns500(b *restful.RouteBuilder) {

b.Returns(http.StatusInternalServerError, "Bummer, something went wrong", nil)

}
