Golang Controller.ServeJson方法代码示例

//判断是否登陆

			c.Redirect("/admin/login", 301)
		case 1:
			//返回JSON
			json := &models.TipJSON{}
			json.Status = models.TipError
			json.Message = "请先登录，再执行此操作"
			json.ReturnUrl = "/admin/login"

			c.Data["json"] = json
			c.ServeJson()
			c.StopRun()
		}

	}
	c.Data["AdminName"] = username
	c.Data["AdminId"] = id
	c.Layout = "admin/layout.tpl"
}

//信息提示，如果异步，返回json、如果同步，则页面提示并返回
func EchoTip(c *beego.Controller, json *models.TipJSON) {
	if c.IsAjax() {

		c.Layout = tpl
		//此处不能用 c.StopRun() 返回，否则会空白页面！
		//c.StopRun()
