LoadRunner中HTTP協議的錄制及兩種錄制模式的比較
一，腳本編寫
1， “HTML –base scrīpt”和“URL-base scrīpt”的區別
1）“HTML –base scrīpt”默認模式，為每個用戶請求生成單獨的函數
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”可以捕獲所有作為用戶操作的結果發送到服務器的HTTP請求，然后一一記錄下來�？梢圆东@非HTML應用程序，例如小程序和非瀏覽器應用程序。
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/",

"Mode=HTTP",
LAST);

}
3）如何選擇？什么時候選擇url的錄制方式：
* 不是基于瀏覽器的
* 基于瀏覽器但是包含javascrīpt，并且發送了請求到服務器
* 使用了https 安全協議
4）兩種腳本的內容比較：
* http腳本直觀，易于理解和維護
* url 內容多，可伸縮性強，記錄了更詳細的用戶操作信息。
2，HTML 高級選項：
1） 默認是選擇描述用戶行為的腳本
2） 僅包含明確的URL腳本，錄制結果如下：
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);
web_submit_data("login.pl",
"Action=http://127.0.0.1:1080/WebTours/login.pl",
"Method=POST",
"TargetFrame=",
"RecContentType=text/html",
"Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home",
"Snapshot=t5.inf",
"Mode=HTML",
ITEMDATA,
"Name=userSession", "Value=97276.9197245848fAADziVpffiDDDDDDAAccpAiQDf", ENDITEM,
"Name=username", "Value=jojo", ENDITEM,
"Name=password", "Value=bean", ENDITEM,
"Name=JSFormSubmit", "Value=off", ENDITEM,
"Name=login.x", "Value=52", ENDITEM,
"Name=login.y", "Value=8", ENDITEM,
LAST);
return 0;
}
3，錄制header
默認設置是不錄制，選擇需要錄制的Headers，以便服務器能夠正確處理編碼信息。需要注意的是“accept-language”,像websphere這類服務器會根據HTTP 請求中的Header來確定編碼。
