实现方法

添加日志拦截filter

		// 添加日志拦截器
		var FilterLog = func(ctx *context.Context) {
			url, _ := json.Marshal(ctx.Input.Data()["RouterPattern"])
			params, _ := json.Marshal(ctx.Request.Form)
			outputBytes, _ := json.Marshal(ctx.Input.Data()["json"])
			divider := " - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -"
			topDivider := "┌" + divider
			middleDivider := "├" + divider
			bottomDivider := "└" + divider
			outputStr := "\n" + topDivider + "\n│ 请求地址:" + string(url) + "\n" + middleDivider + "\n│ 请求参数:" + string(params) + "\n│ 返回数据:" + string(outputBytes) + "\n" + bottomDivider
			logs.Info(outputStr)
		}
		// 最后一个参数必须设置为false 不然无法打印数据
		beego.InsertFilter("/*", beego.FinishRouter, FilterLog, false)
