使用 vba 和 xmlhttp 自动提交网站上的帖子表单

Question

我在 excel 2010 中通过 vba 使用 xmlhttp。我需要以编程方式将项目添加到网站上的购物车中。到目前为止，我有下面的代码，它使用 POST 方法

我认为我的代码有一些问题，但不确定如何修复 - 它没有显示表单所在的位置已提交。这是该网址：

http://www. craft-e-corner.com/p-2688-new-testament-cricut-cartridge.aspx

我作为处理表单的url输入的url是“action=”部分中的url的“形式”。

如何验证表格是否已发布？

Sub post_frm()
Dim xmlhttp As Object
Set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP")
' Indicate that page that will receive the request and the
' type of request being submitted
xmlhttp.Open "POST", "http://www.craft-e-corner.com/addtocart.aspx?returnurl=showproduct.aspx%3fProductID%3d2688%26SEName%3dnew-testament-cricut-cartridge", False
' Indicate that the body of the request contains form data
xmlhttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
' Send the data as name/value pairs
xmlhttp.send "Quantity=1&VariantID=2705&ProductID=2688"
Set xmlhttp = Nothing
End Sub

Answer 1

代码没有任何问题。 :) 我测试了一下，效果很好。错误可能在其他地方。

我只是稍微调整了代码以使用 IE 来测试输出，现在它工作得很好:) 我现在已经在 Excel 2007 中测试了它。很快将在 2010 年进行测试。顺便说一句，您使用的是哪个版本的 IE？

这是我测试过的代码，它工作得很好。

Option Explicit

Sub post_frm()

    Dim objIE As Object, xmlhttp As Object
    Dim response As String

    Set objIE = CreateObject("InternetExplorer.Application")
    objIE.navigate "about:blank"
    objIE.Visible = True

    Set xmlhttp = CreateObject("MSXML2.ServerXMLHTTP")

    '~~> Indicates that page that will receive the request and the type of request being submitted
    xmlhttp.Open "POST", "http://www.craft-e-corner.com/addtocart.aspx?returnurl=showproduct.aspx%3fProductID%3d2688%26SEName%3dnew-testament-cricut-cartridge", False
    '~~> Indicate that the body of the request contains form data
    xmlhttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
    '~~> Send the data as name/value pairs
    xmlhttp.Send "Quantity=1&VariantID=2705&ProductID=2688"

    response = xmlhttp.responseText
    objIE.document.Write response

    Set xmlhttp = Nothing

End Sub

其他答案的变体适用于我，不需要 IE。

Sub Post_HTTP_Form()
'Requires reference to "Microsoft XML, v6.0" or better. (Tools>References)
    Dim msXML As New XMLHTTP60, resp As String
    With msXML
        .Open "POST", "{http://YOUR_URL_HERE.com}", False
        .setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
        .Send "{PARAMETER}={VALUE}" 
        resp = StrConv(.responseBody, vbUnicode)
    End With
    Debug.Print resp 'outputs to Immediate Window (CTRL+G to view)
    Set msXML = Nothing
End Sub

只需替换{花括号}中的三个值即可。

...以及后期绑定版本：

Sub Post_HTTP_Form()
    Dim msXML As Object, resp As String
    Set msXML = CreateObject("MSXML2.ServerXMLHTTP")
    With msXML
        .Open "POST", "{http://YOUR_URL_HERE.com}", False
        .setRequestHeader "Content-Type", "application/x-www-form-urlencoded"
        .Send "{PARAMETER}={VALUE}" 
        resp = StrConv(.responseBody, vbUnicode)
    End With
    Debug.Print resp 'outputs to Immediate Window (CTRL+G to view)
    Set msXML = Nothing
End Sub
