  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")
       c.Header("Access-Control-Allow-Methods", "POST, GET, OPTIONS")
       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")
       //放行所有OPTIONS方法
      if method == "OPTIONS" {
       c.AbortWithStatus(http.StatusNoContent)
     }
     // 处理请求
      c.Next()
    }
  }
