gin跨域解决方案

cors1.go

package middlewaresimport (        "github.com/gin-gonic/gin"        "net/http")func Cors() gin.HandlerFunc {        return func(c *gin.Context) {                method := c.Request.Method                origin := c.Request.Header.Get("Origin")                if origin != ""{                        c.Header("Access-Control-Allow-Origin", origin)                        //主要设置Access-Control-Allow-Origin                        c.Header("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE, UPDATE")                        c.Header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization")                        c.Header("Access-Control-Expose-Headers", "Content-Length, Access-Control-Allow-Origin, Access-Control-Allow-Headers, Cache-Control, Content-Language, Content-Type")                        c.Header("Access-Control-Allow-Credentials", "false")                        c.Set("content-type", "application/json")                }                if method == "OPTIONS"{                        c.AbortWithStatus(http.StatusNoContent)                }                c.Next()        }}

cors2.go

func Cors() gin.HandlerFunc {        return cors.New(cors.Config{                AllowAllOrigins: false,                AllowOrigins:    nil,                AllowOriginFunc: func(origin string) bool {                        return true                },                AllowMethods:     []string{"GET", "POST", "PUT", "PATCH", "DELETE", "HEAD"},                AllowHeaders:     []string{"Authorization", "ts", "Accept", "Origin", "DNT", "X-CustomHeader", "Keep-Alive", "User-Agent", "X-Requested-With", "If-Modified-Since", "Cache-Control", "Content-Type", "Content-Range", "Range"},                AllowCredentials: true,                MaxAge:           10 * time.Minute,        })}

使用中间件

package routerimport (    "github.com/gin-gonic/gin"    "goproejct/controllers"    "goproejct/middlewares"//引入中间件goproject是项目名 根据自己情况)func InitRouter() {    router := gin.Default()    router.Use(Cors())//使用中间件    v1 := router.Group("v1")    {        v1.POST("/login", controllers.Login)        v1.POST("/regist", controllers.Regist)    }    router.Run(":8000")}
