gin-跨域解决方案

创建中间件

corsMiddleware.go

package middlewares

import (
	"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()
	}
}

使用中间件

router := gin.Default()
router.Use(middlewares.Cors())//使用中间件

package router

import (
    "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(middlewares.Cors())//使用中间件
    v1 := router.Group("v1")
    {
        v1.POST("/login", controllers.Login)
        v1.POST("/regist", controllers.Regist)
    }
    router.Run(":8000")
}
