Question

我一直在尝试使用VBA创建SOAP请求，但每次我得到一个空白的响应。请在下面找到代码。 WSDL网址：http://productavailabilityfeed.xxxx.com/Availability.svc?wsdl

Dim sURL As String
Dim sEnv As String

'Set and Instantiate our working objects
Set objHttp = CreateObject("MSXML2.XMLHTTP")
sURL = "http://productavailabilityfeed.xxxx.com/Product.svc/soap"


' we create our SOAP envelope for submission to the Web Service
 'sEnv = "<?xml version=""1.0"" encoding=""utf-8""?>"
 'sEnv = sEnv & "<soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope"">"
 sEnv = "<soapenv:Envelope xmlns:soapenv=""http://schemas.xmlsoap.org/soap/envelope/"" xmlns:tem=""http://tempuri.org/"">"
 sEnv = sEnv & "  <soap:Header>"
 sEnv = sEnv & "  <soap:Body>"
 sEnv = sEnv & "   <tem:GetAccommodationByCode>"
 sEnv = sEnv & "    <!--Optional:-->"
 sEnv = sEnv & "    <tem:getAccommodationByCodeRequest>"
 sEnv = sEnv & "    <!--Optional:-->"
 sEnv = sEnv & "   <tem:credentials>"
 sEnv = sEnv & "  <!--Optional:-->"
 sEnv = sEnv & "  <tem:username>?</tem:username>"
 sEnv = sEnv & "<!--Optional:-->"
 sEnv = sEnv & "<tem:password>?</tem:password>"
 sEnv = sEnv & "</tem:credentials>"
 sEnv = sEnv & "<!--Optional:-->"
 sEnv = sEnv & "<tem:accommodationCode>?</tem:accommodationCode>"
 sEnv = sEnv & "<!--Optional:-->"
 sEnv = sEnv & "<tem:imageSize></tem:imageSize>"
 sEnv = sEnv & "<!--Optional:-->"
 sEnv = sEnv & "<tem:interval></tem:interval>"
 sEnv = sEnv & "</tem:getAccommodationByCodeRequest>"
 sEnv = sEnv & "</tem:GetAccommodationByCode>"
 sEnv = sEnv & "</soapenv:Body>"
 sEnv = sEnv & "</soapenv:Envelope>"

'we invoke the web service
'use this code snippet to invoke a web service which requires authentication
 objHttp.Open "GET", sURL, False
 objHttp.setRequestHeader "Content-Type", "text/xml"
objHttp.setRequestHeader "SOAPAction", "http://tempuri.org/xxxx/GetAccommodationByCode"

objHttp.send sEnv
MsgBox objHttp.responseText
'clean up code
Set objHttp = Nothing
Set XMLDOC = Nothing

你肯定有错误：

objHttp.Open "GET", sURL, False

应替换为：

objHttp.Open "POST", sURL, False

这个错误不会让你前进。纠正此错误后，您可能需要调试soap消息。所以，在你改变之后，你可以告诉我们它是如何发展的。

无法通过使用VBA的SOAP请求从Web服务获得响应
