在经典 ASP 中使用 WinHttpRequest.ResponseStream（与 IStream 相关）？
有没有办法使用 ResponseStream 属性 rel="nofollow">WinHttp.WinHttpRequest.5.1 在 VBScript/ASP 中？至少有 IStream 接口（ ResponseStream相关）在一定程度上集成到ASP中。
或者这是您在脚本中可以实现的限制？如果您想更进一步，需要您推出自己的 COM 组件吗？
<html><body><h1>WinHttp</h1>
<%
Dim req, url, o
Set req = CreateObject( "WinHttp.WinHttpRequest.5.1" )
url = "http://www.google.de"
req.Open "GET", url, False
req.Send
Response.Write "<p>Hier kommt <code>" & url & "</code> :</p>"
Response.Write "<pre>"
Response.Write req.Status & " " & req.StatusText & VbNewLine
Response.Write req.GetAllResponseHeaders
Response.Write "</pre>"
' Response.Write Mid( req.ResponseText, InStr( req.ResponseText, "<div" ) )
' Set o = req.ResponseStream
' o = req.ResponseStream
' Same result for Write and BinaryWrite:
' VarType = 13, TypeName = Unknown
' ASP 0106 : 80020005; Typkonflikt; Unbehandelter Datentyp
' o = req.ResponseStream
' o = req.ResponseBody ' mit BinaryWrite
o = req.ResponseText ' mit Write
Response.Write "<p><code>IsObject " & IsObject(o) & "</code></p>"
Response.Write "<p><code>IsNull " & IsNull(o) & "</code></p>"
Response.Write "<p><code>VarType " & VarType(o)
Response.Write " " & TypeName(o) & "</code></p>"
Response.Write o
' Response.BinaryWrite o
%>
请注意，我知道我可以使用 req.ResponseText 或 req.ResponseBody。感兴趣的是知道您是否可以使用仅针对 C 记录但也许（推测）脚本可访问的内容来进一步编写脚本。我对COM一无所知。
Is there a way to work with the ResponseStream property of WinHttp.WinHttpRequest.5.1 in VBScript/ASP? At least the IStream interface (to which ResponseStream is related) is integrated into ASP to a certain degree.
Or is that the limit of what you can achieve in script? Requiring you to roll your own COM component if you want to go any further?
<html><body><h1>WinHttp</h1>
<%
Dim req, url, o
Set req = CreateObject( "WinHttp.WinHttpRequest.5.1" )
url = "http://www.google.de"
req.Open "GET", url, False
req.Send
Response.Write "<p>Hier kommt <code>" & url & "</code> :</p>"
Response.Write "<pre>"
Response.Write req.Status & " " & req.StatusText & VbNewLine
Response.Write req.GetAllResponseHeaders
Response.Write "</pre>"
' Response.Write Mid( req.ResponseText, InStr( req.ResponseText, "<div" ) )
' Set o = req.ResponseStream
' o = req.ResponseStream
' Same result for Write and BinaryWrite:
' VarType = 13, TypeName = Unknown
' ASP 0106 : 80020005; Typkonflikt; Unbehandelter Datentyp
' o = req.ResponseStream
' o = req.ResponseBody ' mit BinaryWrite
o = req.ResponseText ' mit Write
Response.Write "<p><code>IsObject " & IsObject(o) & "</code></p>"
Response.Write "<p><code>IsNull " & IsNull(o) & "</code></p>"
Response.Write "<p><code>VarType " & VarType(o)
Response.Write " " & TypeName(o) & "</code></p>"
Response.Write o
' Response.BinaryWrite o
%>
Note that I know I can use either req.ResponseText or req.ResponseBody. The interest is in knowing whether you can go further in script using stuff that's only documented for C but maybe (speculating) accessible to script. I'm not knowledgeable about COM.

您无法直接在脚本代码中对 IStream 执行任何操作。您所能做的就是将其传递给可能使用它的 COM 对象。
IStream 与 Vbscript 非常陌生，即使在 VB6 中，也必须跳过一些困难才能使用它。
There is nothing you can do with an IStream directly in script code. All you could do is pass it to a COM object that might use it.
The IStream is very alien to Vbscript even in VB6 one has to jump through some fiery hoops to work with it.
