Gin best practices, gin development scaffolding, too late to explain, get on the bus.
使用gin构建了企业级脚手架，代码简洁易读，可快速进行高效web开发。 主要功能有：
- 请求链路日志打印，涵盖mysql/redis/request
- 支持多语言错误信息提示及自定义错误提示。
- 支持了多配置环境
- 封装了 log/redis/mysql/http.client 常用方法
- 支持swagger文档生成

- 安装软件依赖 go mod使用请查阅：
https://blog.csdn.net/e421083458/article/details/89762113
git clone [email protected]:e421083458/gin_scaffold.git
cd gin_scaffold
go mod tidy
-
确保正确配置了 conf/mysql_map.toml、conf/redis_map.toml：
-
运行脚本
go run main.go
➜ gin_scaffold git:(master) ✗ go run main.go

- 测试mysql与请求链路
创建测试表：
CREATE TABLE `area` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`area_name` varchar(255) NOT NULL,
`city_id` int(11) NOT NULL,
`user_id` int(11) NOT NULL,
`update_at` datetime NOT NULL,
`create_at` datetime NOT NULL,
`delete_at` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8 COMMENT='area';
INSERT INTO `area` (`id`, `area_name`, `city_id`, `user_id`, `update_at`, `create_at`, `delete_at`) VALUES (NULL, 'area_name', '1', '2', '2019-06-15 00:00:00', '2019-06-15 00:00:00', '2019-06-15 00:00:00');
curl 'https://127.0.0.1:8880/demo/dao?id=1'
{
"errno": 0,
"errmsg": "",
"data": "[{\"id\":1,\"area_name\":\"area_name\",\"city_id\":1,\"user_id\":2,\"update_at\":\"2019-06-15T00:00:00+08:00\",\"create_at\":\"2019-06-15T00:00:00+08:00\",\"delete_at\":\"2019-06-15T00:00:00+08:00\"}]",
"trace_id": "c0a8fe445d05b9eeee780f9f5a8581b0"
}
查看链路日志（确认是不是一次请求查询，都带有相同trace_id）：

- 下载对应操作系统的执行文件到$GOPATH/bin下面
如下：
➜ gin_scaffold git:(master) ✗ ll -r $GOPATH/bin
total 434168
-rwxr-xr-x 1 niuyufu staff 13M 4 3 17:38 swag
- 设置接口文档参考：
controller/demo.go的 Bind方法的注释设置
// ListPage godoc
// @Summary 测试数据绑定
// @Description 测试数据绑定
// @Tags 用户
// @ID /demo/bind
// @Accept json
// @Produce json
// @Param polygon body dto.DemoInput true "body"
// @Success 200 {object} middleware.Response{data=dto.DemoInput} "success"
// @Router /demo/bind [post]
- 生成接口文档：
swag init - 然后启动服务器：
go run main.go，浏览地址: https://127.0.0.1:8880/swagger/index.html
