Cobra 命令行 因为之前写 Django，python manage.py这个命令非常好用，想看看能不能实现类似的效果。搜索之后发现了更强的cobra，看简介中使用的项目就知道非常不错。代码组织参考的frp的。 PATH/frp/cmd，frpc和fprs分别是客户端和服务端 ├───frpc │ │ main.go │ │ │ └───sub │ http.go │ https.go │ reload.go │ root.go │ status.go │ stcp.go │ sudp.go │ tcp.go │ tcpmux.go │ udp.go │ xtcp.go │ └───frps main.go root.go 添加 go get -u github.com/spf13/cobra/cobra 在项目目录中执行，appname mycli，其中cmd中 rootCmd 的名称是mycli，这里建议和appname一样，后面可以直接go install之后使用mycli即可。 mkdir cmd && cd cmd cobra init mycli --pkg-name mycli cmd └───mycli │ LICENSE │ main.go │ └───cmd root.go 模板代码 import错误，重新按照自己项目的组织方式重写 import即可。 package main import "mycli/cmd" func main() { cmd.Execute() } 测试使用： ...
