代码案例

package main

import (
	"fmt"
	"net/http"
	_ "net/http/pprof"
)

func main(){
	for i := 0; i < 5; i++ {
		go func() {
			select {
			default:
				return
			}
		}()
	}
	go func() { select {} }()  // 泄漏协程
	if err := http.ListenAndServe(":8080", nil); err != nil {
		fmt.Println("start pprof failed")
	}
}
