推荐答案

这些图像后面是基于服务器的脚本，例如php，python等，可以获取并记录有关访问者的信息(访问页面，引荐来源网址，ip， ...)的跟踪统计信息.服务器将能够从http请求中获取您可以在服务器端获取的所有信息.这种方法的好处是，它几乎可以在所有浏览器和设备上运行.它也是轻量级的，因为1x1图像将导致几乎零带隙.

Behind these image is a server-based script like php, python or so on which can get and log information about the visitor (visited page, referer, ip, ...) for the tracking-stats. The server will be able to get all information you can get on the serverside from a http-request. The benefits of this methods are that it works on nearly all browsers and devices. Its also lightweight because an 1x1 image will cause nearly zero bandwitch.

它是跟踪网页浏览量的常用解决方案.为了获得更大的灵活性，某些替代跟踪方法(例如pwiki)甚至不使用javascript.他们正在插入一个跟踪像素，当用户禁用了javascript或他正在使用一些可删除跟踪脚本的插件时，该像素也可以使用.

Its a common solution to track pageviews. To get more flexible, some alternative tracking-methods like pwiki don't even use javascript. They're inserting a tracking-pixel which also works when the user has javascript disabled or he is using some plugins which remove tracking-scripts.

它也适用于电子邮件，因此发件人可以了解有关哪些用户以及多少用户阅读的信息，例如新闻邮件.但是如今，几乎所有桌面和Web客户端默认都阻止电子邮件中的图像，以阻止这些跟踪方法.仅当用户明确允许特定域使用此图像时，才会显示图像.

It also works on emails so that the sender has information about which and how much users read for example a newsletter-mail. But nowadays nearly all deskto- and webclients are blocking images in emails by default to prevent these tracking-methods. Images will only be displayed when the user explicit allow this for a specific domain.
