Question

我正在尝试打开然后将包含图像作为.GIF扩展名的网页保存到我的桌面。以下代码为我打开了一个测试页：

Sub test()
    Dim IE As Object, Doc As Object
    Set IE = CreateObject("internetexplorer.application")
    IE.Visible = True
    IE.Navigate "http://www.orseu-concours.com/54-189-thickbox/epso-numerical-reasoning-test-2-en.jpg"

    Do While IE.ReadyState <> 4: DoEvents: Loop
    Set Doc = CreateObject("htmlfile")
    Set Doc = IE.Document
End Sub

下一步是将页面保存为.GIF。执行此操作的手动过程是右键单击图像并按保存，然后将.gif扩展名添加到名称或另一种方法是只按页面上的CTRL + S并将其另存为图像。

我已经尝试了API函数 URLDownloadToFile 但是每次刷新页面时我用于我的应用程序的图像都会更新，因此我要求保存的图像与打开的图像相同，因此无法使用以上功能导致两个不同的图像。

如果可能的话，我试图避免使用SendKeys。

根据我的评论，请尝试以下操作（原始代码here）：

Sub main()
'downloads google logo
HTTPDownload "https://www.google.tn/images/srpr/logo11w.png", "d:\logo11w.png"
End Sub
Sub HTTPDownload(myURL, myPath)
' This Sub downloads the FILE specified in myURL to the path specified in myPath.
'
' myURL must always end with a file name
' myPath may be a directory or a file name; in either case the directory must exist

    ' Standard housekeeping
    Dim i, objFile, objFSO, objHTTP, strFile, strMsg
    Const ForReading = 1, ForWriting = 2, ForAppending = 8

    ' Create a File System Object
    Set objFSO = CreateObject("Scripting.FileSystemObject")

    ' Check if the specified target file or folder exists,
    ' and build the fully qualified path of the target file
    If objFSO.FolderExists(myPath) Then
        strFile = objFSO.BuildPath(myPath, Mid(myURL, InStrRev(myURL, "/") + 1))
    ElseIf objFSO.FolderExists(Left(myPath, InStrRev(myPath, "\") - 1)) Then
        strFile = myPath
    Else
        WScript.Echo "ERROR: Target folder not found."
        Exit Sub
    End If

    ' Create or open the target file
    Set objFile = objFSO.OpenTextFile(strFile, ForWriting, True)

    ' Create an HTTP object
    Set objHTTP = CreateObject("WinHttp.WinHttpRequest.5.1")

    ' Download the specified URL
    objHTTP.Open "GET", myURL, False
    objHTTP.Send

    ' Write the downloaded byte stream to the target file
    For i = 1 To LenB(objHTTP.ResponseBody)
        objFile.Write Chr(AscB(MidB(objHTTP.ResponseBody, i, 1)))
    Next

    ' Close the target file
    objFile.Close
End Sub

编辑： IE将图像存储在临时文件夹中，以便您可以从那里拾取它并使用上面的函数更改扩展名。

这是对这个问题的共鸣：Open webpage and save image

Private Declare Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" ( _
ByVal pCaller As Long, ByVal szURL As String, ByVal szFileName As String, ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long





Private Sub Command1_Click()
    Dim sin As String
    Dim sout As String

    Dim ret As Long

    sin = "https://www.google.tn/images/srpr/logo11w.png"
    sout = Environ("HOMEPATH") & "\Desktop\" & "logo11w.png"

    ret = URLDownloadToFile(0, sin, sout, 0, 0)
    If (ret = 0) Then MsgBox "Succedded" Else MsgBox "failed"
End Sub
