Gin基本使用

简介

Gin的实现非常简单，准备开始编写属于自己的微服务吧！

创建Gin Engine

通过gin.Default()和gin.New创建Engine，区别在于Default()会默认使用Logger和Recover中间件

// Default returns an Engine instance with the Logger and Recovery middleware already attached.
func Default() *Engine {
    debugPrintWARNINGDefault()
    engine := New()
    engine.Use(Logger(), Recovery())
    return engine
}

路由组

路由组可以在api中添加前缀，比如”/api/v1”

package main
import (
    "net/http"
    "github.com/gin-gonic/gin"
)
func main() {
    router := gin.Default()
    v1 := router.Group("/api/v1/todos")
    {
        v1.GET("/", func(ctx *gin.Context) { ctx.JSON(http.StatusOK, "ok") })
    }
    router.Run(":8080")
}
