这个Web服务方法有什么问题？

更新：Problem solved。

我必须调用一个Web服务方法（dduLogin），它返回3个参数。我通过visual studio“添加web引用”生成了代码。这是wsdl的相关部分：

<message name="dduLoginRequest">
    <part name="Ticket" type="xsd:string"/>
    <part name="ServiceId" type="xsd:string"/>
    <part name="Market" type="xsd:string"/>
    <part name="Application" type="xsd:string"/>
    <part name="Brand" type="xsd:string"/>
    <part name="Sincom" type="xsd:string"/>
    <part name="CertificationSystem" type="xsd:string"/>
</message>  


<message name="dduLoginResponse">
    <part name="Ticket" type="xsd:string"/>
    <part name="LoginId" type="xsd:string"/>
    <part name="Return" type="xsd:string"/>
</message>
<portType name="dduPortType">
    <operation name="dduLogin">
        <input message="tns:dduLoginRequest"/>
        <output message="tns:dduLoginResponse"/>
    </operation>


</portType>
<binding name="dduBinding" type="tns:dduPortType">
    <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
    <operation name="dduLogin">
        <soap:operation soapAction="urn:ddu#dduLogin" style="rpc"/>
        <input>
            <soap:body use="encoded" namespace="urn:ddu" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
        </input>
        <output>
            <soap:body use="encoded" namespace="urn:ddu" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
        </output>
    </operation>


</binding>

可以调用此方法，这是返回的xml：

<SOAP-ENV:Body><ns1:dduLoginResponse xmlns:ns1="urn:ddu">
    <Ticket xsi:type="xsd:string">M-S%40%2AT6%2F%26179G%23%24%25%25%2A%40%40LDNT%27BP%3F9C%2CRY9-Z8C0C%3D0JXD%24_%2A%5EFKF%26DV%3BIP_8%3DM.E3VBDU7%3CAB%5C9_%22%3A%29E9%2CYO6%5C8I%5D6J%5EZ%60%2C8%3A%26%60%25U%3B.6A4G%2BO%5EQA%5DINI4X2%247%29M%2C%3B%3DZ%5CQ%3C%3A%27%3AB%5CSUB%3F9GAPC%3DRV%3CA%5E%2CE7%40L3%3F%3FY%215T%27%40B%3FKUJIH%3D%2B150Q%3CD%3A%3B%21D%22%3B%3ED%60%60%0A</Ticket>
    <LoginId xsi:type="xsd:string">22459</LoginId>
    <Return xsi:type="xsd:string">0</Return></ns1:dduLoginResponse>
</SOAP-ENV:Body>

但是在通话结束后，并非所有的返回值都应该填充。这是Visual Studio为该方法生成的代码：

[System.Web.Services.Protocols.SoapRpcMethodAttribute("urn:ddu#dduLogin", RequestNamespace="urn:ddu", ResponseNamespace="urn:ddu")]
[return: System.Xml.Serialization.SoapElementAttribute("LoginId")]
public string dduLogin(ref string Ticket, string ServiceId, string Market, string Application, string Brand, string Sincom, string CertificationSystem, out string Return) {
    object[] results = this.Invoke("dduLogin", new object[] {
        Ticket,
        ServiceId,
        Market,
        Application,
        Brand,
        Sincom,
        CertificationSystem});
    Ticket = ((string)(results[1]));
    Return = ((string)(results[2]));
    return ((string)(results[0]));
}

结果是错误的顺序（票证应该是results[0]），而LoginId应该是results[1]而results[1]也是空的（null）。

这里有什么问题？我错过了什么吗？这是一个糟糕的wsdl？它是Visual Studio Web服务代理生成器吗？以前有人这么做过吗？关于如何解决这个问题的任何建议？

Btw，一位同事能够使用另一个Web服务工具集（完全不与.NET相关）成功调用此Web服务。

更新

我遵循了@Benjamin's建议，并使用WCF创建了一个客户端。我确实遇到了一些问题：wsdl包含一些不应该有空格的空格，服务的编码显然是ISO-8859-1，所以我最终创建了自己的CustomTextMessageEncoder。

由于我期待使用此服务的更多问题，我仍然非常有兴趣使用旧式Web服务引用，所以如果有人有另一个线索为什么返回的xml没有被解析，这是wsdl的网址：

  

https://eu.link.fiatauto.com/tsi/DDUWsAut.php?wsdl

请注意，删除空格（这是我在尝试服务引用方式时遇到的问题）不解决了这个问题（wsdl.exe的输出在没有空格的情况下仍然相同）。

3 个答案:

答案 0 :(得分：1)

我有类似的问题，当我使用WCF（即：添加服务引用而不是Web引用）来生成代理类时，它们就消失了。

答案 1 :(得分：1)

您可以尝试使用wsdl.exe工具创建代理类文件，而不是使用“添加引用”。如果您使用代理类具有相同的缺失返回值问题，则可以手动编辑代理类文件以解决问题。

Wsdl.exe用 http://msdn.microsoft.com/en-us/library/7h3ystb6%28VS.80%29.aspx

您的问题可能类似于此博文中描述的问题。 http://blogs.msdn.com/eugeneos/archive/2007/02/05/solving-the-disappearing-data-issue-when-using-add-web-reference-or-wsdl-exe-with-wcf-services.aspx

答案 2 :(得分：1)

我向服务提供商提出了这个问题，经过一些故障排除（他们无法首先重现），很明显，同一服务显然有2个不同的端点：

我使用的默认值：

  

https://eu.link.fiatauto.com/tsi/DDUWsAut.php

和他们正在使用的另一个（显然专门针对dotnet客户端）：

  

https://eu.link.fiatauto.com/tsi/DDUWsAutDotNet.php

为什么需要这个仍然不清楚，但使用dotnet特定端点而不是另一个端点解决了我的问题，所以我没有再问任何问题。
