谢谢指导,这种方法实际与telnet效果相同,在我司的环境中即使不能访问指定的站点,但是ping,telnet到80端口还是可以的,因此这种方法适用于一般的环境但不适用于我目前的情况.

试试xmlhttp看看返回什么错误

请问xmlhttp指的是哪个函数,第三方UDF吗?

netegg 发表于 2012-3-29 13:41:22

楼主这个问题没说清楚吧，指的是外网还是内网，外网的话直接ping个域名就行了，内网的话，检查四个'端口'

我的问题是检查外网,公司的PC只要开机是一直连接的,但访问外网则需经代理服务器,代理服务器上有针对不同级别帐号的策略,部分帐号可能被禁止访问大部分网址但ping和telnet到80端口都是可以的.

2003?不太会玩了

不是的,代理服务器是硬件代理,一般的PC是XP的

和我们公司是一样，你要在代理服务器上下工夫
判断PC，你要先判断登陆的账户不是？除非人手一台电脑

看来只有14楼的方法(使用InetGet根据下载的内容)来判断用户能否访问Intenet了

502762378 发表于 2012-3-29 18:47:02

恩判断回执当然可以，虽然笨了点，其实这个问题没有意义，代理服务器有很多功能你自己琢磨呗

谢谢指导，代码返回访问页面的内容，该方法仍需判断返回内容才能确定当前帐号在PC上能否访问Internet，使用以下代码时遇到不能准确判断结果，不知道是否由于内容太多导致变量$sData无法存放所有的内容导致的呢？#include "WinHttp.au3"

Opt("MustDeclareVars", 1)

; Initialize
Global $hOpen = _WinHttpOpen()

If @error Then
MsgBox(48, "Error", "Error initializing the usage of WinHTTP functions.")
Exit 1
EndIf

; Specify what to connect to
Global $hConnect = _WinHttpConnect($hOpen, "www.baidu.com") ; <- yours here
If @error Then
MsgBox(48, "Error", "Error specifying the initial target server of an HTTP request.")
_WinHttpCloseHandle($hOpen)
Exit 2
EndIf

; Create request
Global $hRequest = _WinHttpOpenRequest($hConnect)
If @error Then
MsgBox(48, "Error", "Error creating an HTTP request handle.")
_WinHttpCloseHandle($hConnect)
_WinHttpCloseHandle($hOpen)
Exit 3
EndIf

; Send it
_WinHttpSendRequest($hRequest)
If @error Then
MsgBox(48, "Error", "Error sending specified request.")
_WinHttpCloseHandle($hRequest)
_WinHttpCloseHandle($hConnect)
_WinHttpCloseHandle($hOpen)
Exit 4
EndIf

; Wait for the response
_WinHttpReceiveResponse($hRequest)

MsgBox(48, "Error", "Error waiting for the response from the server.")

_WinHttpCloseHandle($hConnect)
_WinHttpCloseHandle($hOpen)

Local $fid=FileOpen("a.txt", 16)
Local $data=FileRead($fid)
If @error Then MsgBox(0,1,'error')
FileClose($fid)
$fid=FileOpen("b.txt", 16 + 2)
FileWrite($fid, $data)
FileClose($fid)
Exit
用此代碼測試250m的檔案是ok的, 你的網頁不會超過250m吧
