VBS中的HTTP GET

Question

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

Answer 1

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.

Answer 2

您还没有在撰写本文时描述您将如何处理响应或其内容类型。答案已经包含 MSXML2.XMLHTTP 的一个非常基本的用法（我推荐更明确的 MSXML2.XMLHTTP.3.0 progID）但是你可能需要对响应做不同的事情，它可能不是文字。

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 ，它是一个 IStream 包装器为了回应。

请注意，在服务器端需求（例如，ASP中托管的VBScript）中，您将使用 MSXML.ServerXMLHTTP.3.0 或 WinHttp.WinHttpRequest.5.1 （其中包含一个接近完全相同的界面。）

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

Answer 3

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 os版本和补丁程序具有不同的名称。

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.... 

....还有更多东西，但只是让请求通过。

        strRequest = "<soap:Envelope xmlns:soap=""http://www.w3.org/2003/05/soap-envelope"" " &_
         "xmlns:tem=""http://tempuri.org/"">" &_
         "<soap:Header/>" &_
         "<soap:Body>" &_
            "<tem:Authorization>" &_
                "<tem:strCC>"&1234123412341234&"</tem:strCC>" &_
                "<tem:strEXPMNTH>"&11&"</tem:strEXPMNTH>" &_
                "<tem:CVV2>"&123&"</tem:CVV2>" &_
                "<tem:strYR>"&23&"</tem:strYR>" &_
                "<tem:dblAmount>"&1235&"</tem:dblAmount>" &_
            "</tem:Authorization>" &_
        "</soap:Body>" &_
        "</soap:Envelope>"

        EndPointLink = "http://www.trainingrite.net/trainingrite_epaysystem" &_
                "/trainingrite_epaysystem/tr_epaysys.asmx"



dim http
set http=createObject("Microsoft.XMLHTTP")
http.open "POST",EndPointLink,false
http.setRequestHeader "Content-Type","text/xml"

msgbox "REQUEST : " & strRequest
http.send strRequest

If http.Status = 200 Then
'msgbox "RESPONSE : " & http.responseXML.xml
msgbox "RESPONSE : " & http.responseText
responseText=http.responseText
else
msgbox "ERRCODE : " & http.status
End If

Call ParseTag(responseText,"AuthorizationResult")

Call CreateXMLEvidence(responseText,strRequest)

'Function to fetch the required message from a TAG
Function ParseTag(ResponseXML,SearchTag)

 ResponseMessage=split(split(split(ResponseXML,SearchTag)(1),"</")(0),">")(1)
 Msgbox ResponseMessage

End Function

'Function to create XML test evidence files
Function CreateXMLEvidence(ResponseXML,strRequest)

 Set fso=createobject("Scripting.FileSystemObject")
 Set qfile=fso.CreateTextFile("C:\Users\RajkumarJoshua\Desktop\DCIM\SampleResponse.xml",2)
 Set qfile1=fso.CreateTextFile("C:\Users\RajkumarJoshua\Desktop\DCIM\SampleReuest.xml",2)

 qfile.write ResponseXML
 qfile.close

 qfile1.write strRequest
 qfile1.close

End Function
