从超链接下载图片到特定文件夹

Question

我有一个 excel 文件，其中包含文件夹名称 (col A)、图片名称 (col B) 和超链接 (col C) p>

文件夹名称图片名称网址

文件夹 1 图像 1 超链接 1

文件夹2图片2超链接2

文件夹 3 图像 3 超链接 3

我找到了这段代码：

Option Explicit

Private Declare PtrSafe 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

Dim Ret As Long

'~~> This is where the images will be saved. Change as applicable
Const FolderName As String = "c:\TEMP\"

Sub Sample()

Dim ws As Worksheet
Dim LastRow As Long, i As Long
Dim strPath As String

'~~> Name of the sheet which has the list
Set ws = Sheets("Sheet1")

LastRow = ws.Range("A" & Rows.Count).End(xlUp).Row

For i = 2 To LastRow '<~~ 2 because row 1 has headers
    strPath = FolderName & ws.Range("B" & i).Value & ".jpg"

    Ret = URLDownloadToFile(0, ws.Range("C" & i).Value, strPath, 0, 0)

    If Len(Dir(FolderName, vbDirectory)) = 0 Then
        MkDir FolderName
    End If

    If Ret = 0 Then
        ws.Range("C" & i).Value = "File successfully downloaded"
    Else
        ws.Range("C" & i).Value = "Unable to download the file"
    End If
Next i

End Sub

它将文件下载到 C:\TMP\ 但我希望它连续下载每个文件到相应的文件夹 (col A)

这很简单。

由于您使用 CONSTANT 作为保存目录Const FolderName As String = "c:\TEMP\"，如果您将代码复制粘贴到您的工作簿中，您不会走得太远。

您应该首先尝试了解代码的工作原理并尝试一下，但无论如何......

如果不插入Const 行，您必须Dim 一个变量，该变量将包含您的目录字符串，并且每次更改行时都会更改。基本上在这里：

For i = 2 To LastRow

    FolderName = ws.Range("A" & i).text ' this is how you get the folder name from column "A" every line
    strPath = FolderName & ws.Range("B" & i).Value & ".jpg"

    Ret = URLDownloadToFile(0, ws.Range("C" & i).Value, strPath, 0, 0)

    If Len(Dir(FolderName, vbDirectory)) = 0 Then
        MkDir FolderName
    End If

    If Ret = 0 Then
        ws.Range("C" & i).Value = "File successfully downloaded"
    Else
        ws.Range("C" & i).Value = "Unable to download the file"
    End If
Next i
