1.安装swag

2.添加注释
注释项:

version: 版本
description、termsOfService、 contact 非必要声明。
license.name apache2.0。
host、 BasePath: 如果直接swagger调试API,需要填写正确,host为服务文档的端口ip,BasePath为基础路径, 这里是“/api/v1”。
还有securityDefinitions.basic、securityDefinitions.apikey等

3.生成(更新)api文档
1 2 3 | // 进入项目根目录(即main.go所在) $ cd proj $ swag init |
4.编译运行试试看
1 2 | $ go mod init test $ go build && ./test |
