我使用以下脚本从基本的经过身份验证的SOAP Web服务获取响应。下面的代码将凭据放在HTTP标头中，因此我没有得到响应。
如何使用VBScript更新SOAP标头中的凭据？
我的代码：
Set objHTTP = CreateObject("Msxml2.ServerXMLHTTP")
objHTTP.setOption 2, 13056
strTextContent = Trim("Content of my request xml")
strUserName = "mylogin"
strPassword = "mypassword"
strURL = "myendpoint"
objHTTP.Open "GET", strURL, False, strUserName, strPassword
objHTTP.setRequestHeader "Authorization", "Basic " & Base64Encode(strUserName & ":" & strPassword)
objHTTP.setRequestHeader "Content-Type", "text/xml; charset=utf-8"
objHTTP.setRequestHeader "SOAPAction", "mysoapaction"
objHTTP.send strTextContent
strResponseReceived = objHTTP.responseText
MsgBox strResponseReceived
