1：获取包
go get github.com/feixiao/httpprof2：进入所在目录，获取依赖
govendor sync
3：编译运行example
go build
4：外部项目添加使用，只需要参考example的使用即可
func Index(w http.ResponseWriter, r *http.Request, _ httprouter.Params) {
fmt.Fprint(w, "Welcome!\n")
}
func Hello(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
fmt.Fprintf(w, "hello, %s!\n", ps.ByName("name"))
}
func main() {
router := httprouter.New()
// 在原来的httprouter的使用基础只是添加了这一句代码
router = httpprof.WrapRouter(router)
router.GET("/", Index)
router.GET("/hello/:name", Hello)
log.Fatal(http.ListenAndServe(":8080", router))
}
