如何创建和实施像素跟踪代码 [英] How to create and implement a pixel tracking code
问题描述
好的，这是我一直在寻找的目标.
OK, here's a goal I've been looking for a while.
众所周知，大多数广告和分析公司都使用所谓的像素"代码来跟踪网站的浏览，交易，转化等.
As it's known, most advertising and analytics companies use a so called "pixel" code in order to track websites views, transactions, conversion etc.
我确实对它的工作原理有一个大致的了解，问题是如何实现它.跟踪代码由几部分组成.
I do have a general idea on how it works, the problem is how to implement it. The tracking codes consist from few parts.
-
跟踪代码本身. 这是用户在
<head>部分中的网页上插入的代码.该代码的主要目标是设置一些客户特定的变量并调用*.js文件.
The tracking code itself. This is the code that the users inserts on his webpage in the
<head>section. The main goal of this code is to set some customer specific variables and to call the*.jsfile.
*.js文件.
该文件包含所有CRUD(创建/读取/更新/删除)cookie的魔力，可跟踪用户的事件以及与网页的交互.
*.js file.
This file holds all the magic of CRUD (create/read/update/delete) cookies, track user's events and interaction with the webpage.
像素代码.
这是一个<img>标记，其中src属性指向图像*.gif(例如)文件，该文件采用页面上收集的所有参数，并将它们存储在数据库中.
The pixel code.
This is an <img> tag with the src atribute pointing to an image *.gif (for example) file that takes all the parameters collected on the page, and stores them in the database.
示例:
WordPress像素代码:<img id="wpstats" src="http://stats.wordpress.com/g.gif?host=www.hostname.com&list_of_cookies_value_pairs;" alt="">
WordPress pixel code: <img id="wpstats" src="http://stats.wordpress.com/g.gif?host=www.hostname.com&list_of_cookies_value_pairs;" alt="">

现在，很明显，*.gif请求必须到达服务器端脚本语言才能读取参数数据并将其存储在db中.
Now, it's obvious that the *.gif request has to reach a server side scripting language in order to read the parameters data and store them in a db.
有人知道如何在Zend中实现这一点吗?
Does anyone have an idea how to implement this in Zend?
更新
我感兴趣的另一件事是:如何避免用户的浏览器加载缓存的*.gif?随机参数值可以解决问题吗?例如:src="pixel.gif?nocache=random_number"，其中每个请求的nocache参数值都将不同.
UPDATE
Another thing I'm interested in is: How to avoid the user's browser to load the cached *.gif ? Will a random parameter value do the trick? Example: src="pixel.gif?nocache=random_number" where the nocache parameter value will be different on every request.
推荐答案
As Zend is built using PHP, it might be worth reading the following question and answer: Developing a tracking pixel.
除了这个答案，而且您正在寻找一种避免缓存跟踪图像的方法时，最简单的方法是在运行时生成一个唯一/随机的字符串.
In addition to this answer and as you're looking for a way of avoiding caching the tracking image, the easiest way of doing this is to append a unique/random string to it, which is generated at runtime.
例如，在服务器端以及创建每个图像时，您可以添加一个随机URL ID:
For example, server-side and with the creation of each image, you might add a random URL id:
<?php
// Generate random id of min/max length
$rand_id = rand(8, 8);
// Echo the image and append a random string
echo "<img src='pixel.php?a=".$vara."&b=".$varb."&rand=".$rand_id."'>";
?>
