[zeromicro/go-zero]框架没有接入pprof 进行性能剖析吗?

go-zero 如何接入 pprof 工具，我这简单总结了下： https://laomiao.site/go-zero-%E5%A6%82%E4%BD%95%E6%8E%A5%E5%85%A5-pprof

有内置的，看 core/prof 包

好的，我看看，谢谢

这个就不需要了，删掉

//我根据博主文档整理一份完整demo，goctl1.3.5生成的API
package main

    flag.Parse()

你好，使用kill -usr2 后 打不开trace.pprof文件，其他文件可以打开

go tool pprof core-1-trace-1201111253.pprof core-1-trace-1201111253.pprof: parsing profile: unrecognized profile format failed to fetch any source profiles

我是这样实现的，创建/ProjectName/api/internal/handler/monitor.go文件，然后在里面增加pprof相关的Handler，最后在main里面handler.RegisterMonitorHandler(server, ctx)导入就好啦。

package handler

import (
    "github.com/zeromicro/go-zero/rest"
    "net/http"
    "net/http/pprof"
    "ticket_saas/api/internal/svc"
)

func RegisterMonitorHandler(server *rest.Server, serverCtx *svc.ServiceContext) {
    server.AddRoutes(
        rest.WithMiddlewares(
            []rest.Middleware{},
            []rest.Route{
                {
                    Method:  http.MethodGet,
                    Path:    "/debug/pprof",
                    Handler: pprof.Index,
                },
                {

                    Handler: pprof.Handler("allocs").ServeHTTP,
