LoadRunner中HTTP协议的录制及两种录制模式的比较

一，脚本编写

1，  “HTML –base scrīpt”和“URL-base scrīpt”的区别

1）“HTML –base scrīpt”默认模式，为每个用户请求生成单独的函数

如：

Action()

{

web_url("WebTours",

        "URL=http://127.0.0.1:1080/WebTours/",

        "Resource=0",

        "RecContentType=text/html",

        "Referer=",

        "Snapshot=t4.inf",

        "Mode=HTML",

        LAST);

       web_submit_form("login.pl",

        "Snapshot=t5.inf",

        ITEMDATA,

        "Name=username", "Value=jojo", ENDITEM,

        "Name=password", "Value=bean", ENDITEM,

        "Name=login.x", "Value=53", ENDITEM,

        "Name=login.y", "Value=13", ENDITEM,

        LAST);

return 0;

}

2）“URL-base scrīpt”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，然后一一记录下来。可以捕获非HTML应用程序，例如小程序和非浏览器应用程序。

如：

Action()

{



web_url("WebTours",

        "URL=http://127.0.0.1:1080/WebTours/",

        "Resource=0",

        "RecContentType=text/html",

        "Referer=",

        "Snapshot=t1.inf",

        "Mode=HTTP",

        LAST);



web_concurrent_start(NULL);



web_url("header.html",

        "URL=http://127.0.0.1:1080/WebTours/header.html",

        "Resource=0",

        "RecContentType=text/html",

        "Referer=http://127.0.0.1:1080/WebTours/",

        "Snapshot=t2.inf",

        "Mode=HTTP",

        LAST);



web_url("welcome.pl",

        "URL=http://127.0.0.1:1080/WebTours/welcome.pl?signOff=true",

        "Resource=0",

        "RecContentType=text/html",

        "Referer=http://127.0.0.1:1080/WebTours/",

        "Snapshot=t5.inf",

        "Mode=HTTP",

        LAST);



web_concurrent_end(NULL);



web_concurrent_start(NULL);

}

3）如何选择？什么时候选择url的录制方式：

* 不是基于浏览器的

* 基于浏览器但是包含javascrīpt，并且发送了请求到服务器

* 使用了https 安全协议

4）两种脚本的内容比较：

* http脚本直观，易于理解和维护

* url 内容多，可伸缩性强，记录了更详细的用户操作信息。

2，HTML 高级选项：

1）  默认是选择 描述用户行为的脚本

2）  仅包含明确的URL脚本，录制结果如下：

Action()

{



     web_url("WebTours",

            "URL=http://127.0.0.1:1080/WebTours/",

            "TargetFrame=",

            "Resource=0",

            "RecContentType=text/html",

            "Referer=",

            "Snapshot=t1.inf",

            "Mode=HTML",

            LAST);





     web_url("Update.htm",

            "URL=http://scdown.qq.com/download/Update.htm",

            "TargetFrame=",

            "Resource=0",

            "RecContentType=text/html",

            "Referer=",

            "Snapshot=t2.inf",

            "Mode=HTML",

            LAST);



     web_url("Update.htm_2",

            "URL=http://scdown.qq.com/download/Update.htm",

            "TargetFrame=",

            "Resource=0",

            "RecContentType=text/html",

            "Referer=",

            "Snapshot=t3.inf",

            "Mode=HTML",

            LAST);



     web_url("Update.htm_3",

            "URL=http://scdown.qq.com/download/Update.htm",

            "TargetFrame=",

            "Resource=0",

            "RecContentType=text/html",

            "Referer=",

            "Snapshot=t4.inf",

            "Mode=HTML",

            LAST);
