Question

我还是初学者，但我可以阅读简单的html结构。

然而，在网站https://stockrow.com/AAPL/financials/income/annual上，我尝试使用 xmlhttprequest 将数据提取到excel中，但源数据缺少包含所有关键值的重要表格。当我检查网站时，我可以看到整个HTML结构。

这是我得到的源数据：

<!DOCTYPE html>
<html lang="en">
  <head>
    <link rel="apple-touch-icon-precomposed" sizes="57x57" 
href="/favicons/apple-touch-icon-57x57.png" />

<script async id="_ck_381101" src="https://forms.convertkit.com/381101?v=7"></script>

我不知道如何解决这个问题，所以我想我会尝试堆栈溢出。

Answer 1

如果您只需要网站显示的数据，您实际上可以使用VBA打开IE实例并要求IE为您搜索数据。这有点像黑客，但它会完成这项工作。

基本上，请使用浏览器检查网站，并查看哪些元素包含您想要的数据。在VBA脚本中，您可以要求VBA收集元素中包含的数据。

仔细查看HTML页面，您会发现可以下载xlsx。实际上，您只需复制与元素的href相关联的URL，然后将其传递给URLMon即可直接下载。

摘要：

 <a class="button hollow expanded" href="/api/companies/AAPL/financials.xlsx?dimension=MRY&amp;section=Income Statement" target="_blank">Export to Excel (.xlsx)</a>

href是相对的，因此您需要将主机域放在最前面。

VBA：

Option Explicit

#If VBA7 And Win64 Then
    Private Declare PtrSafe Function URLDownloadToFile Lib "urlmon" _
    Alias "URLDownloadToFileA" ( _
    ByVal pCaller As LongPtr, _
    ByVal szURL As String, _
    ByVal szFileName As String, _
    ByVal dwReserved As LongPtr, _
    ByVal lpfnCB As LongPtr _
    ) As Long

#Else
    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

#End If

Public Const BINDF_GETNEWESTVERSION As Long = &H10
Public Const folderName As String = "C:\Users\HarrisQ\Desktop\info.xlsx" '<=Change as required

Public Sub downloadPDF()
    Dim ret As Long
    ret = URLDownloadToFile(0, "https://stockrow.com/api/companies/AAPL/financials.xlsx?dimension=MRY&amp;section=Income Statement", folderName, BINDF_GETNEWESTVERSION, 0)

End Sub
