Can'；t获取Web刮表以填充多个单元格VBA

我正试图通过VBA从网站上抓取一张表。我能够从表格中收集所有数据，但我只能将其填充到单个单元格中，而不是按照网站上的格式分解信息。基本上，数据应该在四列中，然后按数据的行数向下移动。我知道我在这里遗漏了一些简单的东西，但我就是不知道该怎么办。救命啊！编码如下：

Sub WebScrape()

Dim objIE As InternetExplore'

Dim ele As Object
Dim y As Integer
objIE.navigate "http://www.uscfinvestments.com/holdings/usci"
Do While objIE.Busy = True Or objIE.readyState <> 4: DoEvents: Loop

y = 1
For Each ele In objIE.document.getElementById("holdingsTableDiv").getElementsByTagName("table")
    Debug.Print ele.textContent
    Sheets("Sheet1").Range("A" & y).Value = ele.Children(0).textContent
Next
ActiveWorkbook.Save

End Sub

Sub-WebScrape（）
Dim objIE作为InternetExplore'
作为对象的Dim ele
Dim y作为整数
objIE.navigate“http://www.uscfinvestments.com/holdings/usci"
Do While objIE.Busy=True或objIE.readyState 4:DoEvents:Loop
y=1
对于objIE.document.getElementById（“holdingsTableDiv”）.getElementsByTagName（“表格”）中的每个元素
调试。打印ele.textContent
工作表（“Sheet1”）.Range（“A”和“y”）.Value=ele.Children（0）.textContent
下一个
活动工作簿。保存
端接头

我在下面展示了一些方法。就个人而言，我更喜欢使用API的最后一个

使用剪贴板：

如果您想在页面上显示，一个简单的方法是将表复制到剪贴板并粘贴

Option Explicit
Public Sub GetInfo()
    Dim ie As InternetExplorer, hTable As Object, clipboard As Object, ws As Worksheet, t As Date
    Const MAX_WAIT_SEC As Long = 10
    Set ws = ThisWorkbook.Worksheets("Sheet1")
    Set clipboard = GetObject("New:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}")
    Set ie = New InternetExplorer

    With ie
        .Visible = True
        .Navigate2 "http://www.uscfinvestments.com/holdings/usci"

        While .Busy Or .readyState < 4: DoEvents: Wend

        t = Timer
        Do
            On Error Resume Next
            Set hTable = .document.getElementById("holdingsTableID")
            On Error GoTo 0
            If Timer - t > MAX_WAIT_SEC Then Exit Do
        Loop While hTable Is Nothing

        If Not hTable Is Nothing Then
            clipboard.SetText hTable.outerHTML
            clipboard.PutInClipboard
            ws.Cells(1, 1).PasteSpecial
        End If
        .Quit
    End With
End Sub

它需要身份验证。我正在使用解析返回的json。下载并添加.bas后，需要转到VBE>Tools>References>Add a reference to

Microsoft脚本运行时

Option Explicit
Public Sub GetValues()
    Dim json As Object, authorization As String
    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", "http://www.uscfinvestments.com/uscfinvestments-template/assets/javascript/api_key.php", False
        .send
        authorization = Split(Split(.responseText, "'")(1), "'")(0)
        .Open "GET", "https://cssecure.alpsinc.com/api/v1//holding/usci", False
        .setRequestHeader "Authorization", authorization
        .send
        Set json = JsonConverter.ParseJson(.responseText)
    End With
    Dim arr(), headers(), item As Object, r As Long
    headers = Array("Security", "Quantity", "Price", "Market Value")
    r = 1
    ReDim arr(1 To json.Count, 1 To 4)
    For Each item In json
        arr(r, 1) = item("name")
        arr(r, 2) = item("shares")
        Dim test As String
        If IsNull(item("contractprice")) Then
           arr(r, 3) = item("settlementprice")
        Else
            arr(r, 3) = item("contractprice")
        End If
        arr(r, 4) = item("marketvalue")
        r = r + 1
    Next
    With ThisWorkbook.Worksheets("Sheet1")
        .Cells(1, 1).Resize(1, UBound(headers) + 1) = headers
        .Cells(2, 1).Resize(UBound(arr, 1), UBound(arr, 2)) = arr
    End With
End Sub

这里没有什么可补充的。QHarr已经报道过了。我使用了硬编码延迟而不是显式等待来减少脚本的冗长

Sub GetContent()
    Dim Html As HTMLDocument, elem As Object, tRow As Object, C&, R&

    With New InternetExplorer
        .Visible = False
        .navigate "http://www.uscfinvestments.com/holdings/usci"
        While .Busy = True Or .readyState < 4: DoEvents: Wend
        Set Html = .Document
    End With

    Application.Wait Now + TimeValue("00:00:03") 'make it 05 if it fails somehow

    For Each elem In Html.getElementById("holdingsTableID").Rows
        For Each tRow In elem.Cells
            C = C + 1: ThisWorkbook.Worksheets("Sheet1").Cells(R + 1, C) = tRow.innerText
        Next tRow
        C = 0: R = R + 1
    Next elem
End Sub

Sub-GetContent（）
Dim Html作为HTMLDocument，elem作为Object，tRow作为Object，C&，R&
使用新的InternetExplorer
.Visible=False
.导航“http://www.uscfinvestments.com/holdings/usci"
While.Busy=True或.readyState<4:DoEvents:Wend
设置Html=.Document
以
Application.Wait Now+TimeValue（“00:00:03”）“如果以某种方式失败，则将其设为05
对于Html.getElementById（“holdingsTableID”）行中的每个元素
对于元素单元中的每一步
C=C+1：此工作簿。工作表（“Sheet1”）。单元格（R+1，C）=tRow.innerText
下一步
C=0:R=R+1

您从未增加您的

y

计数器，因此每次循环迭代都会覆盖上一次循环写入的值。立即窗格中是否显示正确/完整的内容（来自这些

Debug.Print

语句），您只向A列写入内容。可能需要迭代

tr

元素，以了解何时递增

y

。是的，所有信息都已完成，但只显示在A1中。正如Mathieu Guindon所说，它只显示在A1中，因为您唯一的写入赋值是

范围（“A”&y）

，这是硬编码到

A列的，您将
y
的值设置为1，然后再也不更改它。如果有API，一定要使用它。当存在API时，从HTTP请求中删除Web内容可能违反TOS（不过，无论是否存在API，Web删除内容也可能违反TOS），谢谢@QHarr！太完美了！谢谢你的帮助！
