我試圖製作一個自動註冊在網頁中的bot（在Autoit中）。 我嘗試獲取圖像時出現問題。我用下面的代碼在Autoit上獲取ReCaptcha圖像
$imgCaptchaId = _IEGetObjById($oForm,"recaptcha_challenge_image")
$imgCaptcha = $imgCaptchaId.src
Local $sFile
GUICreate("Captcha Image",400,200)
$sFile = _GetURLImage($imgCaptcha, @TempDir & "\Captcha.jpg")
GUICtrlCreatePic($sFile,0,0,300,100)
GUISetState(@SW_SHOW)
Sleep(3000)
EndFunc
Func _GetURLImage($sURL, $sDirectory = @ScriptDir)
Local $hDownload, $sFile
$sFile = StringRegExpReplace($sURL, "^.*/", "")
If @error Then
Return SetError(1, 0, $sFile)
EndIf
If StringRight($sDirectory, 1) <> "\" Then
$sDirectory = $sDirectory & "\"
EndIf
$sDirectory = $sDirectory & $sFile
If FileExists($sDirectory) Then
Return $sDirectory
EndIf
$hDownload = InetGet($sURL, $sDirectory, 17, 1)
While InetGetInfo($hDownload, 2) = 0
If InetGetInfo($hDownload, 4) <> 0 Then
InetClose($hDownload)
Return SetError(1, 0, $sDirectory)
EndIf
Sleep(105)
WEnd
InetClose($hDownload)
Return $sDirectory
EndFunc ;==>_GetURLImage
，這裏是網絡源的一部分
