主要学习Web（HTTP/HTML）协议的两种录制方式，重点包括以下内容：
--脚本录制的基本原则
--HTML和URL based script介绍
--选择录制方式的原则
--HTML based script设置介绍
1、脚本录制的基本原则
（1）充分考虑脚本的执行效率。
性能测试脚本关注的是如何模拟用户的真实行为。因此，用于测试的脚本应该接近用户的真实操作。这就要求录制后的脚本在修改的过程中不要增加过多内容，尤其是不能降低其运行效率。例如尽量不要增加循环、检查等操作，除非这些操作是必须的。
"基于此：检查点的设置一定要合理"
（2）录制重要的用户业务
要录制常用的、使用频率较高的业务来进行测试，不要什么内容都录制。
（3）选择需要的进行录制
在Web性能测试中，如果有些操作对于用户所关注的事物没有什么影响，那么可以不进行录制。例如，一些查询事物中，选择查询条件页面的请求过程可以不予录制，但对于一些要传递查询参数的过程则必须录制。（即凡是与Server服务器端进行交互的必须录制）
（4）录制前对参数要进行正确的配置
2、HTML和URL based script介绍
（1）基本概要
HTML based script：可以为每个用户请求生成单独的函数。
URL based script：可以捕获所有作为用户操作的结果发送到服务器的HTTP请求，然后一条条记录下来。它甚至可以捕获非HTML的程序，比如小程序和非浏览器应用程序。
HTML这种录制方式录制出来的脚本直观，易于理解和维护。而URL生成的脚本看起来比较长比较多。
（2）选择配置路径
当然还可以在：Tools-->>Recording Options处进行选择设置。
（3）两种录制方式录制出的脚本比较。
录制场景：Web Tours网站的登陆和退出
使用HTML based script录制的脚本如下显示：

3、通过两种录制方式的比较，我们得出脚本录制的原则，如下：
[1]基于浏览器的应用程序推荐使用HTML-based Script。
不是基于浏览器的应用程序推荐使用URL-based Script。
[2]如果基于浏览器的应用程序中包含了JavaScript并且该脚本向服务器产生了请求，比如DataGrid的分页按钮等，也要使用URL方式录制。
[3]基于浏览器的应用程序中使用了HTTPS安全协议，使用URL方式进行录制。
[4]对于初学者来说，如果HTML录制方式不成功，可以换成URL方式录制。
4、HTML based script设置介绍
（1）用来描述用户行为的脚本。直接创建的URL(web-url)、表单提交(Web_submit_form)、链接(Web_link)、和图像(Web_image)等函数。
（2）仅包含明确的URL脚本。这些脚本中所有的链接、图像请求和URL操作都被录制为Web_url函数，而表单提交则被录制为Web_submit_data函数。
