Question

我得到了这个需要调用的web服务结构。 ws名称是Set_Details我把它弄好了，所以不能导致错误。我无法弄清楚如何解决这个问题。当我打电话给它时我得到了错误：

System.InvalidOperationException：Set_Details Web服务方法名称无效。在System.Web.Services.Protocols.Protocol.Partocol.Potocol.Potocol.Partocol.Potocol.Pit上的System.Web.Services.Protocols.HttpServerProtocol.Initialize（）处于System.Web.Services.Protocols.Protocol.SetContext（Type类型，HttpContext上下文，HttpRequest请求，HttpResponse响应）。 Create（Type type，HttpContext context，HttpRequest request，HttpResponse response，Boolean＆amp; abortProcessing）

  <soap:Body>
    <Set_Details xmlns="http://ws.blobobobo.uk/WebService/">
      <Details>
        <Number>int</Number>

      <LoginID>string</LoginID>
      <LoginPassword>string</LoginPassword>
    </Set_Details>
  </soap:Body>
</soap:Envelope>

这是我的代码，我称之为类webservice

  dim ws
      set ws = new webservice
      ws.url = mainip
      ws.method = "Set_OrderDetails"

      ws.parameters.Add "Number", "6166""
      ws.parameters.Add "Category", "ffff"

      ws.parameters.Add "LoginID", "ex10"
      ws.parameters.Add "LoginPassword", "ex20"


    ws.execute


    response.write ws.response
set ws = nothing

这是我的代表网络服务的课程

通过执行原始HTTP POST调用SOAP Web服务方法时，您应该构建并发送Web服务所描述的整个请求。即你需要发送：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <Set_Details xmlns="http://ws.blobobobo.uk/WebService/">
      <Details>
        <Number>6166</Number>
        <Category>ffff</Category>
      </Details>
      <LoginID>ex10</LoginID>
      <LoginPassword>ex20</LoginPassword>
    </Set_Details>
  </soap:Body>
</soap:Envelope>

目前你正在发帖：

Number=6166&Category=ffff&LoginID=ex10&LoginPassword=ex20

Web服务管道层不知道如何处理它。

您的Web服务方法也接受复杂类型Details，因此您必须将请求作为HTTP POST和完整的胖请求（信封，正文等）发送。

您还需要在请求中设置SOAPAction HTTP标头，例如：

SOAPAction: "http://ws.blobobobo.uk/WebService/Set_Details"

<强>更新

这是一个完全有效的例子：

<%
result = Set_Details(6166, "ffff", "ex10", "ex20")
Response.Write result

Function Set_Details(number, category, loginID, loginPassword)

  Dim request, doc, xmlHttp, url
  url = "http://ws.bloblobo.uk/WebServices/ws.asmx"

  request = "<?xml version='1.0' encoding='utf-8'?>" & _
    "<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>" & _
    "  <soap:Body>" & _
    "    <Set_Details xmlns='http://ws.blobobobo.uk/WebService/'>" & _
    "      <Details>" & _
    "        <Number>" & number  & "</Number>" & _
    "        <Category>" & category & "</Category>" & _
    "      </Details>" & _
    "      <LoginID>" & loginID & "</LoginID>" & _
    "      <LoginPassword>" & loginPassword & "</LoginPassword>" & _
    "    </Set_Details>" & _
    "  </soap:Body>" & _
    "</soap:Envelope>"

  Set xmlHttp = CreateObject("MSXML2.ServerXMLHTTP")
  xmlHttp.open "POST", url, False
  xmlHttp.setRequestHeader "Content-Type", "text/xml; charset=utf-8"
  xmlHttp.setRequestHeader "SOAPAction", _
          """http://ws.blobobobo.uk/WebService/Set_Details"""

  xmlHttp.send request

  Set response = xmlHttp.responseXML

  '' The presumption here is that you get some kind of result back. 
  '' The example here assumes that the `Set_Details` method returns a simple type 
  '' such as a string, number or boolean
  result = response.documentElement.selectSingleNode("//Set_DetailsResult").text

  Set_Details = result

End Function

%>

最后从不使用Microsoft.XMLHTTP发出HTTP请求，它不打算用于ASP或服务器端应用程序，而是使用MSXML2.ServerXMLHTTP。
