gin-解决跨域问题

1.在middlewares中创建cors.go文件

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

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())

?

1	package initializeimport (   "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}
