我正在测试一款通过激活代理来限制网站的软件。似乎有一个错误，代理刚刚停止工作，但只是在网上冲浪大约一两个小时，或者点击数百甚至数千个链接之后。

是否有现有的解决方案可以做到这一点？如果我能以这种方式解决它，我也对编程解决方案感兴趣。

我听说过 firefox 的greasemonkey 插件，但我不熟悉javascript。有没有办法让javascript随机收集页面上的链接，然后随机打开其中一个？

Sounds like the proxy might have a session timeout of about an hour (absolute) or about an hour of "no activity".

Leaving aside whether it's a good testing methodology, here's a complete Greasemonkey script that clicks random links:

// ==UserScript==
// @name     _YOUR_SCRIPT_NAME
// @include  http://YOUR_SERVER.COM/YOUR_PATH/*
// ==/UserScript==

var timeDelaySeconds    = 2;

setInterval (clickRandomLink, timeDelaySeconds * 1000);

function clickRandomLink () {
    var links = document.querySelectorAll ("a");
    /*--- Or fine-tune the links to certain areas or types.  EG:
        var links = document.querySelectorAll ("#content a");
        var links = document.querySelectorAll ("a.comments");
        etc.
    */
    if (links.length) {
        var linkToClick = links[getRandomInt (0, links.length - 1) ];
        var clickEvent  = document.createEvent ('MouseEvents');

        clickEvent.initEvent ('click', true, true);
        linkToClick.dispatchEvent (clickEvent);
    }
}

function getRandomInt (min, max) {
    return Math.floor (Math.random () * (max - min + 1) ) + min;
}

It uses a time-delay to allow for links to AJAX-in. It uses querySelectorAll() to allow for fine-tuning which links are used, and it sends an actual click event, as that is the most robust way to trigger the most kinds of links.
