gin 框架解决跨域问题

package main

import (
	"gin_es7/es"
	"github.com/gin-contrib/cors"
	"github.com/gin-gonic/gin"
	"time"
)

func Atime(t string) string {
	//fmttime := "2020-08-14 00:00:00"
	localtime, _ := time.ParseInLocation("2006-01-02 15:04:05", t, time.Local)
	return localtime.UTC().Format("2006-01-02T15:04:05.000Z")
}

func main() {


	r := gin.Default()
	newCors := cors.New(cors.Config{
		AllowOrigins:  []string{"*"},
		AllowMethods:  []string{"POST, GET, OPTIONS, PUT, DELETE"},
		AllowHeaders:  []string{"Origin", "Authorization", "Content-Type"},
		ExposeHeaders: []string{"Content-Type"},
		AllowOriginFunc: func(origin string) bool {
			return true
		},
		//超时时间设定
		MaxAge: 24 * time.Hour,
	})
	r.Use(newCors)
	r.GET("/fcn-data/resptime", func(c *gin.Context) {
		stime := c.DefaultQuery("stime", "2020-08-13 00:00:00")
		dtime := c.DefaultQuery("dtime", "2020-08-27 00:00:00")
		demain := c.DefaultQuery("demain", "api.yungehuo.com")
		api := c.DefaultQuery("api", "yungehuo-account/companysupplierrelation")
		esstime := Atime(stime)
		esdtime := Atime(dtime)
		c.JSON(200, es.RespTimeQuery(demain, api, esstime, esdtime, stime, dtime))
	})
	r.Run("0.0.0.0:8392") // listen and serve on 0.0.0.0:8080
}
