在Linux环境下调试Golang代码,可以使用以下几种常用的调试工具:
Delve
go install github.com/go-delve/delve/cmd/dlv@latest
dlv debug ./debug-demo
(b)reak main.go:10
(c)
ontinue(n)
ext 或 (s)tep
(p)rint variableName
(bt)
GDB
sudo apt-get install gdb
go build -gcflags "-N -l" -o hello-world hello-world.go
gdb ./hello-world
(gdb) break main.go:5
(gdb) run
(gdb) next
或 (gdb) step
(gdb) print variableName
(gdb) quit
Goland
pprof
net/http/pprof
包,启动HTTP服务:import _ "net/http/pprof"
func main() {
go func() {
log.Println(http.ListenAndServe("localhost:6060", nil))
}()
// 你的程序代码
}
http://localhost:6060/debug/pprof/heap
进行堆性能分析。http://localhost:6060/debug/pprof/profile
进行CPU性能分析。Visual Studio Code (VSCode)
launch.json
:{
"version": "0.2.0",
"configurations": [
{
"name": "Launch",
"type": "go",
"request": "launch",
"mode": "debug",
"program": "${fileDirname}",
"env": {},
"args": []
}
]
}
通过这些工具和方法,你可以在Linux环境下高效地调试Golang代码,选择合适的工具取决于你的具体需求和习惯。
