有没有办法在 Visual Basic 脚本中执行 HTTP GET 请求?我需要从特定 URL 获取响应的内容进行处理。

Dim o
Set o = CreateObject("MSXML2.XMLHTTP")
o.open "GET", "http://www.example.com", False
o.send
' o.responseText now holds the response as a string.

在撰写本文时,您还没有描述您将对响应做什么或它的内容类型是什么。一个答案已经包含了一个非常基本的用法MSXML2.XMLHTTP(我推荐更明确的MSXML2.XMLHTTP.3.0progID),但是您可能需要对响应做不同的事情,它可能不是文本。

XMLHTTP 也有一个responseBody属性,它是响应的字节数组版本,并且有一个responseStream它是IStream响应的包装器。

请注意,在服务器端需求(例如,在 ASP 中托管的 VBScript)中,您将使用MSXML.ServerXMLHTTP.3.0WinHttp.WinHttpRequest.5.1(具有几乎相同的界面)。

这是使用 XmlHttp 获取 PDF 文件并存储它的示例:-

Dim oXMLHTTP
Dim oStream

Set oXMLHTTP = CreateObject("MSXML2.XMLHTTP.3.0")

oXMLHTTP.Open "GET", "http://someserver/folder/file.pdf", False
oXMLHTTP.Send

If oXMLHTTP.Status = 200 Then
    Set oStream = CreateObject("ADODB.Stream")
    oStream.Open
    oStream.Type = 1
    oStream.Write oXMLHTTP.responseBody
    oStream.SaveToFile "c:\somefolder\file.pdf"
    oStream.Close
End If

如果您使用 GET 请求实际发送数据...

检查: http ://techhelplist.com/index.php/tech-tutorials/37-windows-troubles/60-vbscript-sending-get-request

MSXML2.XMLHTTP 的问题在于它有多个版本,根据 Windows 操作系统版本和补丁而具有不同的名称。

这解释了它:http: //support.microsoft.com/kb/269238

我有更多的运气使用 vbscript 来调用

set ID = CreateObject("InternetExplorer.Application")
IE.visible = 0
IE.navigate "http://example.com/parser.php?key=" & value & "key2=" & value2 
do while IE.Busy.... 

....还有更多的东西,但只是为了让请求通过。
