如何在Excel中使用VBA进行REST调用？

问题描述

我试图按照这个例子：

但是它出现了这个错误：

此行：

 打印objHTTP.Status 
  

那么如何在VBA中进行POST REST调用？如何使用PUT多部分/表单数据文件在VBA中上传REST调用？

工具>参考文献

代码 $ b
$ b

  Sub SendEmail（）
'Dim objHTTP As New MSXML2.XMLHTTP 
'Set objhttp = CreateObject（WinHttp.WinHttpRequest.5.1 ）
设置objHTTP = CreateObject（MSXML2.ServerXMLHTTP）
 URL =http：// localhost：8888 / rest / mail / send
 objHTTP.OpenPOST，URL ，False 
 objHTTP.send（{key：null，[email protected]至：null，cc null，bcc：null，date：null，subject：我的主题body：null，附件 b $ b打印objHTTP.Status 
打印objHTTP.ResponseText 
 
 End Sub

解决方案

您可能尚未添加对 Microsoft XML （任何版本）的引用 Dim objHTTP As New MSXML2.XMLHTTP 在VBA窗口的工具/引用...对话框中。

此外，避免使用后期绑定（ CreateObject ...）;更好地使用早期绑定（ Dim objHTTP As New MSXML2.XMLHTTP ），因为早期绑定允许您使用Intellisense列出成员并进行各种设计时验证。

I tried to follow this example: http://libkod.info/officexml-CHP-9-SECT-5.shtml - Archive.org - Donate

but it gave this error

on this line:

I tried to use this example: How can I send an HTTP POST request to a server from Excel using VBA?

but it gave this error:

on this line:

Print objHTTP.Status

So how do I make a POST REST call in VBA? How do I make a PUT multi-part/form-data file upload REST call in VBA?

    objHTTP.Open "POST", URL, False
    objHTTP.send ("{""key"":null,""from"":""[email protected]"",""to"":null,""cc"":null,""bcc"":null,""date"":null,""subject"":""My Subject"",""body"":null,""attachments"":null}")
    Print objHTTP.Status
    Print objHTTP.ResponseText

End Sub

解决方案

You probably haven't added a reference to Microsoft XML (any version) for Dim objHTTP As New MSXML2.XMLHTTP in the VBA window's Tools/References... dialog.

Also, it's a good idea to avoid using late binding (CreateObject...); better to use early binding (Dim objHTTP As New MSXML2.XMLHTTP), as early binding allows you to use Intellisense to list the members and do all sorts of design-time validation.
