VBS 中的 HTTP GET

发布于 2024-07-07 21:17:07 字数 69 浏览 9 评论 0原文

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

Is there a way to perform an HTTP GET request within a Visual Basic script? I need to get the contents of the response from a particular URL for processing.

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,您尚未描述您将如何处理该响应或其内容类型。 答案已经包含 MSXML2.XMLHTTP 的非常基本的用法(我建议使用更明确的 MSXML2.XMLHTTP.3.0 progID),但是您可能需要对响应执行不同的操作,它可能不是文本。

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

请注意,在服务器端需求(例如,托管在 ASP 中的 VBScript)中,您将使用 MSXML.ServerXMLHTTP.3.0WinHttp.WinHttpRequest.5.1(它们具有几乎相同的功能)界面)。

以下是使用 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

You haven't at time of writing described what you are going to do with the response or what its content type is. An answer already contains a very basic usage of MSXML2.XMLHTTP (I recommend the more explicit MSXML2.XMLHTTP.3.0 progID) however you may need to do different things with the response, it may not be text.

The XMLHTTP also has a responseBody property which is a byte array version of the reponse and there is a responseStream which is an IStream wrapper for the response.

Note that in a server-side requirement (e.g., VBScript hosted in ASP) you would use MSXML.ServerXMLHTTP.3.0 or WinHttp.WinHttpRequest.5.1 (which has a near identical interface).

Here is an example of using XmlHttp to fetch a PDF file and store it:-

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 的问题是它有多个版本,根据 Windows 的不同,其名称也不同操作系统版本和补丁。

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

我有更多的运气使用 vbscript打电话

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

......还有更多的事情,但只是为了让请求通过。

If you are using the GET request to actually SEND data...

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

The problem with MSXML2.XMLHTTP is that there are several versions of it, with different names depending on the windows os version and patches.

this explains it:
http://support.microsoft.com/kb/269238

i have had more luck using vbscript to call

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

....and more stuff but just to let the request go thru.
