创建一个gin-code-read的项目

cd $GOPATH/src/github.com/gin-code-read
go mod init
go get github.com/gin-gonic/gin

创建main.go

package main

import "github.com/gin-gonic/gin"

func main() {
	r := gin.Default()
	r.GET("ping", func(ctx *gin.Context) {
		ctx.JSON(200, gin.H{"message": "pong"})
	})

	r.Run()

}

利用go-callvis查看调用栈

安装go-callvis

go install github.com/ofabry/go-callvis

查看调用栈

go-callvis main.go

访问localhost:7878

点击gin，会跳到对应的调用栈 http://localhost:7878/?f=github.com/gin-gonic/gin
