动态代理ip的测试步骤有哪些?
2022-04-23 01:47:00 【青果网络gatu】

现在,我们越来越多地使用代理ip,市场上的代理服务商也在不断增加,那么我们如何测试代理的效果呢?看看下面的介绍吧。
1、检测数量。
在进行测评时,样本不能太小,如只进行十多次测试就不能轻易下结论,选择500适度测评量,即每包抽取500个代理进行测试。
2、计算时间。
因为我们有一个测试代理的响应速度的项目,我们需要计算程序请求前和获得响应后的时间间隔,这里我们使用的测试Python库是requests,因此我们只需计算发起请求和获得响应之间的时间间隔。
3、超过时限。
不会在测试时遇到代理请求超时的问题,因此这里我们也需要统一一个超时时间,这里将其设置为60秒,如果使用代理请求百度,还未响应60秒,则认为代理无效。
4、按比例提取现金测定。
此外,评价时还应遵循一个原则,即即现取现测,即取一测一。假设我们一次性提取出100个代理,但这100个代理不同时参与测试,后面的代理将经历一个等待期,如果在一段时间之后再提取出这些代理,那么后面的代理的有效性将受到影响。
5、测试环节。
我们还需要在测试时使用一个稳定且没有反爬虫链接的服务器,这样可以排除服务器的干扰,这里我们以百度为测试目标。
