LoadRunner的Capture Level

場景：錄製loadrunner的web站點

問題：錄製的過程當中發現除了頁面正常的請求外還有些看不懂的請求（包含亂碼），腳本以下：

上面的腳本中出了第一個是指望內的，其餘的出現的很莫名其妙，爲此筆者查閱了相關資料，發現Record Options--NetWork--Port Mapping中的

Capture Level默認選中的爲Socket level data，而關於Capture Level有這麼一段解釋：

一、Socket level data.
Capture data using trapping on the socket level only. Port mappings apply in this case (default).
二、WinINet level data.
Capture data using hooks on the WinINet.dll API used by certain HTTP applications. The most common application that uses these hooks is Internet Explorer. Port mappings are not relevant for this level.
三、Socket level and WinINet level data.
Captures data using both mechanisms. WinINet level sends information for applications that use WinINet.dll. Socket level sends data only if it determines that it did not originate from WinINet.dll. Port mapping applies to data that did not originate from WinINet.dll.

抱着試試看的內心，筆者把Capture Level修改爲WinINet level data，發現腳本中莫名奇妙的內容果真不見了╰(￣▽￣)╮
