用go语言实现在线小词典|青训营笔记

这是我参与「第三届青训营 -后端场」笔记创作活动的的第2篇笔记

一、完整代码

二、运行结果 三、用到的工具 ​

• •  进行一些格式转换的网站，比如json转go strust
• • J​​​​​​​j​​​​​​​https://oktools.net/json2go ​ ​
• •  curl转换器网站
• • curlconverter.com/#go ​ 四、感想

学到了用这两个网站新工具，还会在电脑上安装了git，在vscode配置了go环境，还有一个网页样式的， gitpod.io/#github.com… 应该是叫做gitpod，然后可以用自己的github账号登陆，很方便~
