Go解析命令行参数(简单版本)

// Check Args
if len(os.Args) != 2 {
fmt.Println("Usage xxx <arg1> <arg2>")
return
}

arg1 := os.Args[1]
arg1 := os.Args[2]

可以使用go proxy：https://goproxy.io/zh/
export GO111MODULE=on
export GOPROXY=https://goproxy.io,direct
然后执行go get
go mod init github.com/my/repo

go get github.com/go-redis/redis/v8

[......]

// 获取当前工作目录
wdPath, err := os.Getwd()
if err != nil {
panic(err)
}

// 路径join
vDir := path.Join(wdPath, "path1", "path2")

// 创建目录
os.Mkdir(vDir, os.ModePerm)
[......]

Stream + Copy流
func downloadFile(url string, path string) {
defer wg.Done()

// Get the data
resp, err := http.Get(url)
if err != nil {
panic(err)
}
defer resp.Body.Close()

// Create output file
out, err := os.Create([......]

Run -> Add Configuration -> Launch file，生成launch.json

添加参数
"externalConsole": true,
"args": ["-n","../../test.text"]
