Excel 提交表单并从网站VBA获取数据

我正在尝试使用Excel中的VBA从中获取数据。我尝试做的和有效的是使用InternetExplorer对象，如下所示：

Set IE = CreateObject("InternetExplorer.Application")
IE.Visible = False
IE.Navigate "http://zertifikate.finanztreff.de"
IE.document.getElementById("USFsecuritySearchDropDown").Value = "DE000BP5TBQ2"
IE.document.getElementById("USFsecuritySearchDropDownForm").submit

Do While IE.Busy Or IE.readyState <> 4  'wait until page is loaded
    Application.Wait DateAdd("s", 1, Now)
Loop
MsgBox IE.document.getElementById("BP5TBQ~30~5").innerHTML

，但它总是在我的默认浏览器中打开新窗口，我希望将其隐藏。 在我看来，我缺少XMLHTTP60和MSHTML.HTMLDocument之间的区别。

如果您能帮助我，或者至少告诉我在哪里可以找到这些信息，我将非常感谢……

XMLHTTP向Web服务器发送http请求并收到回复。MSHTML接收字符串并呈现HTML。当您将它们一起使用时，XMLHTTP将获得Web服务器响应，MSHTML将该响应放入您可以使用的表单中

我想你不需要提交任何东西。如果你进入这个网站并输入股票代码，你会看到一个像这样的页面

那里面有股票行情。您可以直接“获取”该URL，并从返回的html中获取所需的任何信息。这个例子得到了我假设的股票价格

Sub GetPrice()

    Dim xHttp As MSXML2.XMLHTTP
    Dim hDoc As MSHTML.HTMLDocument
    Dim hDiv As HTMLDivElement
    Dim hTbl As HTMLTable

    Const sTICKER As String = "DE000BP5TBQ2"

    Set xHttp = New MSXML2.XMLHTTP

    xHttp.Open "GET", "http://zertifikate.finanztreff.de/dvt_einzelkurs_uebersicht.htn?seite=zertifikate&i=22558284&suchbegriff=" & sTICKER & "&exitPoint="
    xHttp.send

    Do Until xHttp.readyState = 4
        DoEvents
    Loop

    If xHttp.Status = 200 Then
        Set hDoc = New MSHTML.HTMLDocument
        hDoc.body.innerHTML = xHttp.responseText

        'Get the third TD in the first TABLE in the first DIV whose class is 'tape'
        Set hDiv = hDoc.getElementsByClassName("tape").Item(0)
        Set hTbl = hDiv.getElementsByTagName("table").Item(0)
        Debug.Print hTbl.getElementsByTagName("td").Item(2).innerText
    End If

End Sub

发布示例

Sub GetPriceByPost()

    Dim xHttp As MSXML2.XMLHTTP
    Dim hDoc As MSHTML.HTMLDocument
    Dim hDiv As HTMLDivElement
    Dim hTbl As HTMLTable

    Const sTICKER As String = "i=635957"

    Set xHttp = New MSXML2.XMLHTTP

    xHttp.Open "POST", "http://fonds.finanztreff.de/fonds_einzelkurs_uebersicht.htn"
    xHttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
    xHttp.send sTICKER

    Do Until xHttp.readyState = 4
        DoEvents
    Loop

    If xHttp.Status = 200 Then
        Set hDoc = New MSHTML.HTMLDocument
        hDoc.body.innerHTML = xHttp.responseText

        'Get the third TD in the first TABLE in the first DIV whose class is 'tape'
        Set hDiv = hDoc.getElementsByClassName("tape").Item(0)
        Set hTbl = hDiv.getElementsByTagName("table").Item(0)
       Debug.Print hTbl.getElementsByTagName("td").Item(2).innerText
    Else
        Debug.Print xHttp.statusText
    End If

End Sub

感谢您向我解释XMLHTTP和MSHTML。首先，我还认为我可以使用GET，但是如果我更改sTICKER=“DE000BP72DA4”，它会显示以前的价格，我认为？I=参数也很重要。我也可以请你编辑你的答案，并告诉我如何提交与职位的形式？你的回答很有帮助，谢谢如果我在网站上输入DE000BP72DA4，我会得到同样的价格。我不会说德语，所以很难说有什么区别。我不知道如何在那个特定的例子中使用post，但我添加了另一个例子。我不知道为什么POST没有使用，但是使用了“fonds…”
