1、fiddle配置 点击Rules选着Customize Rules,在FiddlerScript中找到如下代码进行调整:

2、配置网络延时

oSession["request-trickle-delay"] 上行延迟 数字越大网络越差
oSession["response-trickle-delay"] 下行延迟
延迟对比网络图
 
3、点击Rules-->performance-->Simulate Modem Speeds 弱网配置成功
二、fiddler模拟网络波动
1、在FiddlerScript中找到如下代码进行调整:
 static function randInt(min, max) {
		return Math.round(Math.random()*(max-min)+min);
	}
 if (m_SimulateModem) {
            // Delay sends by 300ms per KB uploaded.
			//随机延迟
			var t = randInt(1,600);
			FiddlerObject.log("随机延迟"+t);
            oSession["request-trickle-delay"] = ""+t; 
            // Delay receives by 150ms per KB downloaded.
            oSession["response-trickle-delay"] = ""+t; 
        }
2、打开Rules-->Performance-->Simulate Modem Speeds 配置OK
