gin设置跨域请求

r = gin.Default()
//解决跨域
r.Use(Cors())

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, PUT, DELETE,UPDATE")      //服务器支持的所有跨域请求的方
      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()
   }
}
