场景：录制loadrunner的web站点
问题：录制的过程中发现除了页面正常的请求外还有些看不懂的请求（包含乱码），脚本如下：
web_url("WebTours", "URL=http://127.0.0.1:1080/WebTours/", "Resource=0", "RecContentType=text/html", "Referer=", "Snapshot=t14.inf", "Mode=HTML", EXTRARES, "Url=http://act.cmcmcdn.com/upload/201507/8afc2fe48db9060fe1bdda2089e1d950.png", ENDITEM, "Url=http://act.cmcmcdn.com/upload/201507/3b491068507d8f85ea7b35d756da7215.png", ENDITEM, LAST); web_url("config.xml", "URL=http://bho.xl7.xunlei.com/platform/2.5.x.xxxx/config.xml", "Resource=0", "RecContentType=text/xml", "Referer=", "Snapshot=t15.inf", "Mode=HTML", LAST); web_custom_request("q.cgi", "URL=http://masterconn.qq.com/q.cgi", "Method=POST", "Resource=1", "Referer=", "Snapshot=t16.inf", "EncType=", "BodyBinary=\\x00\\x02\\x01@\\x00\\x00\\x00\\x04\\x00\\x00\\x00\\xEA\\x00\\x00\\x07\\xDA\\x19\\x9E\\x18\\x08U\\xB3\\x13\\xC8*蘬\\x1F\\xB47偰\\x14S塦\\x00\\x00\\x00\\x04\\x00\\x00\\x00\\x01\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x01\\x00\\x00\\x00\t僬筈鸯GT聍8T\\x98‘\\x13绶鈳0戨\\x07櫬\\xEC\\x1Ey\r\\x13[\\x9F\\x1A忍Q擬\\x13谈]⒍剐ncj\\x04\\xFFw#扊G{\\xA7\\x1A蠍個g:砇绪l鳮\\xFB\\x7F\\x101珥剓聺桇=88bY郔\\xB1\\x0B&_\\x8F\\x1F\\x7F\n泛|紥|\\xC1\r" "l縝V3趔鵔\tK茦X\\x18扨窲詃\\x1F蟎\\x1B#弩\\xFE\\x16茎覚S2，\\xC6\\x1C姷涖uJp穘訫bi曼\\\\\\x08", LAST); return 0;
上面的脚本中出了第一个是期望内的，其他的出现的很莫名其妙，为此笔者查阅了相关资料，发现Record Options--NetWork--Port Mapping中的
Capture Level默认选中的为Socket level data，而关于Capture Level有这么一段解释：
1、Socket level data.
Capture data using trapping on the socket level only. Port mappings apply in this case (default).
2、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.
3、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.
抱着试试看的心里，笔者把Capture Level修改成WinINet level data，发现脚本中莫名奇妙的内容果然不见了╰(￣▽￣)╮
