在Autoit上获取ReCaptcha图像

Question

我正在尝试制作一个自动在网页中注册的机器人程序（在Autoit中）。我在尝试重新捕获图像时遇到了问题。我使用以下代码

$imgCaptchaId = _IEGetObjById($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

这是网络源的一部分

有人能帮我吗？

Answer 1

不需要复杂的下载功能。

$CaptchaFile = @TempDir & "Captcha.jpg"
$imgCaptchaId = _IEGetObjById($oForm,"recaptcha_challenge_image")
$imgCaptcha = $imgCaptchaId.src
GUICreate("Captcha Image",400,200)
FileDelete($CaptchaFile)
InetGet($imgCaptcha, $CaptchaFile)
GUICtrlCreatePic($CaptchaFile,0,0,300,100)
GUISetState(@SW_SHOW)

如果您仍然想使用该函数，请确保GetURLImage返回的是正确的内容。现在它看起来像它的返回目录，但您需要一个完整的文件路径。这个功能一团糟。我打赌问题就在那里。
