使用gin web框架開發，使用 github.com/gin-contrib/pprof 包
import "github.com/gin-contrib/pprof" pprof.Register(router)
輸出圖片相關格式需要先安裝graphviz,graphviz安裝地址如下
https://graphviz.org/download/
web運行起來后，通過命令行執行命令
查看內存使用情況：
go tool pprof http://ip:port/debug/pprof/heap
提醒：如果進入（pprof）模式，輸入web命令，提示錯誤信息為failed to execute dot. Is Graphviz installed? Error: exec: "dot": executable file not found in %PATH%，可能的原因如下：
1. 一個可能是沒有安裝上面的工具
2. 沒有把graphviz/bin目錄配置到path環境變量
3. 如果使用goland等IDE工具打開的terminal，請移步cmd窗口
