How to send and receive XML data in ASP?

In ASP, sending and receiving XML data can be done using the following methods:

  1. To create an XML object, you can use Server.CreateObject(“MSXML2.ServerXMLHTTP”).
  2. Specify the URL and the method of the request (GET or POST), as well as set the request headers.
  3. Use the Send method to send XML data to the server in string form.
  4. To receive the response from the server, you can use the ResponseText property to obtain the text of the response.

Here is an example code:

<%
dim xml, url, method, postData

' 创建XML对象
Set xml = Server.CreateObject("MSXML2.ServerXMLHTTP")

' 设置请求的URL和方法
url = "http://example.com/endpoint"
method = "POST"

' 设置请求头信息
xml.setRequestHeader "Content-Type", "text/xml"
xml.setRequestHeader "User-Agent", "ASP"

' 构建XML数据
postData = "<xml><data>Hello World</data></xml>"

' 发送请求
xml.open method, url, false
xml.send postData

' 获取服务器返回的响应
Response.Write xml.ResponseText

' 释放资源
Set xml = Nothing
%>
  1. The way in which XML data is received depends on the method of the request and the format of the data.
  2. If XML data is sent using the POST method, it can be received using the Request.InputStream object. The Request.BinaryRead method can be used to read the contents of the input stream as a byte array, which can then be converted to a string.
  3. If XML data is sent using the GET method, it can be retrieved using the Request.QueryString object for further processing.

The following is an example code that receives XML data.

<%
dim xmlData

' 接收POST请求的XML数据
If Request.ServerVariables("REQUEST_METHOD") = "POST" Then
    xmlData = Request.BinaryRead(Request.TotalBytes)
    xmlData = BytesToString(xmlData)
End If

' 接收GET请求的XML数据
If Request.ServerVariables("REQUEST_METHOD") = "GET" Then
    xmlData = Request.QueryString("xmlData")
End If

' 处理XML数据
Response.Write "Received XML Data: " & xmlData

Function BytesToString(bytes)
    Dim adoStream
    Set adoStream = Server.CreateObject("ADODB.Stream")
    adoStream.Type = 1 ' adTypeBinary
    adoStream.Open
    adoStream.Write bytes
    adoStream.Position = 0
    adoStream.Type = 2 ' adTypeText
    adoStream.Charset = "UTF-8"
    BytesToString = adoStream.ReadText
    adoStream.Close
    Set adoStream = Nothing
End Function
%>

Please note that the above code is provided as a reference, and you should adjust it according to your actual needs. Make sure that the relevant COM components are registered and available before using Server.CreateObject to create COM objects.
