如何用winhttp的方法获取head信息的某一段[已解决]
如题，先上代码：#include <WinHTTP.au3>
$hOpen = _WinHttpOpen()
$hConnect = _WinHttpConnect($hOpen, "www.baidu.com")
$hRequest = _WinHttpOpenRequest($hConnect, "head", "")
_WinHttpSendRequest($hRequest)
_WinHttpReceiveResponse($hRequest)
Global $sHeader
If _WinHttpQueryDataAvailable($hRequest) Then $sHeader = _WinHttpQueryHeaders($hRequest)
_WinHttpCloseHandle($hRequest)
_WinHttpCloseHandle($hConnect)
_WinHttpCloseHandle($hOpen)
ConsoleWrite($sHeader & @CRLF)
MsgBox(0, "Header", $sHeader)
获取到的head信息如下：HTTP/1.1 200 OK

BDUSERID: 0如果我只想获取其中的Content-Type段或者Cache-Control段，而不是全部获取，当然是不用正则的方式，是用winhttp的方法。不知道可不可以实现。
另外还有另一个问题，就是winhttp的异步模式是如何实现的。 本帖最后由 www378660084 于 2014-8-23 17:20 编辑
看下这个.

pwszName
Pointer to a string that contains the header name. If the flag in dwInfoLevel is not WINHTTP_QUERY_CUSTOM, set this parameter to WINHTTP_HEADER_NAME_BY_INDEX. 发哥好执着
Content-Type：
$sHeader = _WinHttpQueryHeaders($hRequest, $WINHTTP_QUERY_CONTENT_TYPE)
Cache-Control：
$WINHTTP_QUERY_CACHE_CONTROL
