实现一个 http router 库玩玩。。。

資深大佬 : guonaihong 3

brouter

项目一开始时只是一个新的尝试，看能否性能比 httprouter 更快。

项目地址

https://github.com/antlabs/brouter

demo

package main  import (     "fmt"     "net/http"     "log"      "github.com/antlabs/brouter" )  func Index(w http.ResponseWriter, r *http.Request, _ brouter.Params) {     fmt.Fprint(w, "Welcome!n") }  func Hello(w http.ResponseWriter, r *http.Request, ps brouter.Params) {     fmt.Fprintf(w, "hello, %s!n", ps.ByName("name")) }  func main() {     router := brouter.New()     router.GET("/", Index)     router.GET("/hello/:name", Hello)      log.Fatal( http.ListenAndServe(":8080", router)) }

测试结果
