func Cors() gin.HandlerFunc {
	return func(c *gin.Context) {
		method := c.Request.Method
		origin := c.Request.Header.Get("Origin")
		fmt.Println("origin",origin)
		if origin != "" {
			//接收客户端发送的origin (重要!)
			c.Writer.Header().Set("Access-Control-Allow-Origin", origin)
			//服务器支持的所有跨域请求的方法
			c.Header("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE,UPDATE")
			//允许跨域设置可以返回其他子段,可以自定义字段, 要是允许所有可以设置为 *(c.Header("Access-Control-Allow-Headers","*")
			c.Header("Access-Control-Allow-Headers", "Authorization, content-type, Content-Length, X-CSRF-Token, Token,session,Access-Control-Allow-Headers,account")
			
			// 允许浏览器(客户端)可以解析的头部 (重要)
			c.Header("Access-Control-Expose-Headers", "Content-Length, Access-Control-Allow-Origin, Access-Control-Allow-Headers")
			//设置缓存时间
			c.Header("Access-Control-Max-Age", "172800")
			//允许客户端传递校验信息比如 cookie (重要)
			c.Header("Access-Control-Allow-Credentials", "true")
			//c.Set("Content-Type", "application/json")
		}

		//允许类型校验
		if method == "OPTIONS" {
			c.JSON(http.StatusOK, "ok!")
		}

		defer func() {
			if err := recover(); err != nil {
				fmt.Printf("Panic info is: %v\n", err)
			}
		}()
		c.Next()
	}
}
