.net - 如何使用 SOAP 从经典 ASP 调用 .Net Web 服务方法

Question

我正在尝试使用 SOAP 从经典 ASP 调用 .Net Web 服务。我已经构建了以下代码作为测试，并不断返回一个带有 400 Bad Request 错误的空响应体。我做错了什么，或者这个问题可能出在 .Net 方面？

'set up xmlhttp to checkout server
Dim oRequest
Set oRequest = Server.CreateObject("MSXML2.ServerXMLHTTP")

'setting this option will allow ServerXMLHTTP to ignore the certificate errors it encounters.
oRequest.setOption(2) = SXH_SERVER_CERT_IGNORE_ALL_SERVER_ERRORS


' resolve, connect, send, receive - in milliseconds
oRequest.setTimeouts 10000, 10000, 10000, 10000

'set the URL
msURL = "[redacted]"

msSOAP = "<?xml version=""1.0"" encoding=""utf-8"" ?>"
msSOAP = msSOAP & "<soap12:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap12=""http://www.w3.org/2003/05/soap-envelope"">"
msSOAP = msSOAP & "<SOAP:Body>"
msSOAP = msSOAP & "<[Some Service] xmlns=""http://localhost"">"
msSOAP = msSOAP & "<MethodName>"
msSOAP = msSOAP & "<methodParam1>[some value]</methodParam1>"
msSOAP = msSOAP & "<methodParam2>[some value]</methodParam2>"
msSOAP = msSOAP & "<methodParam3>[some value]</methodParam3>"
msSOAP = msSOAP & "</MethodName>"
msSOAP = msSOAP & "</[Some Service]>"
msSOAP = msSOAP & "</SOAP:Body>"
msSOAP = msSOAP & "</soap12:Envelope>"

oRequest.Open "POST", msURL, False
oRequest.setRequestHeader "Content-Type", "text/xml"
oRequest.setRequestHeader "SOAPMethodName", "[MethodName]"
oRequest.setRequestHeader "SOAPAction", "[Some Url]"
oRequest.send msSOAP

Response.Write oRequest.ResponseBody

以下解决方案是我的问题的答案。 Filburt，当我真正进行了一次良好的 SOAP 调用后，我发现您提出的问题非常合理。类型和格式非常重要!

'set up xmlhttp to checkout server
Dim oRequest
Set oRequest = Server.CreateObject("MSXML2.ServerXMLHTTP")

'setting this option will allow ServerXMLHTTP to ignore the certificate errors it encounters.
oRequest.setOption(2) = SXH_SERVER_CERT_IGNORE_ALL_SERVER_ERRORS

' resolve, connect, send, receive - in milliseconds
oRequest.setTimeouts 10000, 10000, 10000, 10000

'set the URL
msURL = "[Service Url]"

msSOAP = "<?xml version=""1.0"" encoding=""utf-8"" ?>"
msSOAP = msSOAP & "<s:Envelope xmlns:s=""http://schemas.xmlsoap.org/soap/envelope/"">"
msSOAP = msSOAP & "<s:Body>"
msSOAP = msSOAP & "<[MethodName] xmlns=""[Some Namespace]"">"
msSOAP = msSOAP & "<methodParam1>[Some value]</methodParam1>"
 msSOAP = msSOAP & "<methodParam2>[Some value]</methodParam2>"
 msSOAP = msSOAP & "<methodParam3>[Some value]</methodParam3>"
   msSOAP = msSOAP & "</MethodName>"
msSOAP = msSOAP & "</s:Body>"
msSOAP = msSOAP & "</s:Envelope>"

oRequest.Open "POST", msURL, False
oRequest.setRequestHeader "Content-Type", "text/xml"
oRequest.setRequestHeader "SOAPAction", "[Some Url]"
oRequest.send msSOAP

我从 url 中去掉了“?wsdl”并稍微改变了信封，现在它可以工作了。我还删除了 SoapMethodName header 的设置。
