一、对所有请求模拟限速
选中simulate modem speeds即为选择限速模式。如果想要取消，再次点击取消即可
那么怎么看到底网速限制为多少了呢？，打开脚本编辑器，找到如下代码：
下面可以设置修改请求延迟3000ms，响应延迟15000ms
if (m_SimulateModem) {
// Delay sends by 300ms per KB uploaded.
oSession["request-trickle-delay"] = "3000";
// Delay receives by 150ms per KB downloaded.
oSession["response-trickle-delay"] = "15000";
}
但是我们实际的网络并不是固定的延迟时间，而是波动的，那么我们可以用如下办法去模拟网络的波动性延迟
static function randInt(min, max) {
return Math.round(Math.random()*(max-min)+min);
}
if (m_SimulateModem) {
// Delay sends by 300ms per KB uploaded.
oSession["request-trickle-delay"] = ""+randInt(1,2000);
// Delay receives by 150ms per KB downloaded.
oSession["response-trickle-delay"] = ""+randInt(1,2000);
}
二、对单个请求模拟限速
上述都是针对所有的请求去限速。但是实际工作中，我们可能有一种场景，想要其他接口是正常的，但是针对某个请求或者某个域名下的请求去限速，那么我们就加上域名限制就可以：
针对某个域名限速：
if (m_SimulateModem && oSession.HostnameIs("www.baidu.com")) {
// Delay sends by 300ms per KB uploaded.
oSession["request-trickle-delay"] = "3000";
// Delay receives by 150ms per KB downloaded.
oSession["response-trickle-delay"] = "15000";
}
针对某个请求限速：
if (m_SimulateModem && oSession.uriContains("/test/service_test/test")) {
// Delay sends by 300ms per KB uploaded.
oSession["request-trickle-delay"] = "3000";
// Delay receives by 150ms per KB downloaded.
oSession["response-trickle-delay"] = "15000";
}
