gin-解决跨域问题

1.在middlewares中创建cors.go文件

package middlewares

import (
	"github.com/gin-gonic/gin"
	"net/http"
)

func Cors() gin.HandlerFunc {
	return func(c *gin.Context) {
		method := c.Request.Method

		c.Header("Access-Control-Allow-Origin", "*")
		c.Header("Access-Control-Allow-Headers", "Content-Type,AccessToken,X-CSRF-Token, Authorization, Token, x-token")
		c.Header("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE, PATCH, PUT")
		c.Header("Access-Control-Expose-Headers", "Content-Length, Access-Control-Allow-Origin, Access-Control-Allow-Headers, Content-Type")
		c.Header("Access-Control-Allow-Credentials", "true")

		if method == "OPTIONS" {
			c.AbortWithStatus(http.StatusNoContent)
		}
	}
}

　　2.使用

在route中添加Use(middlewares.Cors())

package initialize

import (
   "github.com/gin-gonic/gin"
   "mxshop-api/user-web/middlewares"
   "mxshop-api/user-web/router"
)

func Routers() *gin.Engine {
   Router := gin.Default()
   Router.Use(middlewares.Cors())
   ApiGroup := Router.Group("v1")
   router.InitUserRoute(ApiGroup)
   return Router
}
