Go-Zero 官方短链项目教程：快速构建高并发微服务

关于 go-zero，大家可以看文档。为少认为它是中国目前最好用的 golang 微服务框架。

完整的 Go-Zero ShortUrl DevOps Demo

准备工作

我这里直接在 K8S 开发集群中部署相关实例。

生产求稳，建议大家还是买云数据库服务。

部署 Mysql、Redis、Etcd。

部署 Drone、Drone-Runner-Kube

开始探索

准备 DevOps 部署相关配置

验证

我这里已经部署好了一个开发测试的 Pod 实例，大家可以试用。

shorten api 调用

# curl -i "https://shorturl.your-domain.com/shorten?url=https://www.your-domain.com"
curl -i "https://shorturl.hacker-linner.com/shorten?url=https://www.hacker-linner.com"

expand api 调用

# curl -i "https://shorturl.your-domain.com/expand?shorten=6d11a1"
curl -i "https://shorturl.hacker-linner.com/expand?shorten=6d11a1"

利用工具查看 Redis 与 Etcd 中的键值对
