地址不匹配的WSDL2OBJC问题

Question

我已经创建了一个Windows服务，并为它生成了WSDL。我正在使用基本的http绑定。当我试图从IOS (使用生成的basicHttpBinding wsdl2objc类)调用它时，在调用WCF方法之一时会出现一个错误。错误(来自logXMLInOut)指出问题是由于地址错配造成的，但是我不知道如何调试它和\或者我做错了什么。

以下是完整的错误消息：

这是主机app.config

    <services>
        <service 
          behaviorConfiguration="serviceBehavior"
                 name="HelloIndigo.HelloIndigoService">

            <endpoint address="HelloIndigoService"
                      binding="basicHttpBinding"
                      bindingNamespace="FredIannon.TestService"
                      name="basicHttp"
                      contract="HelloIndigo.IHelloIndigoService" />

            <endpoint binding="mexHttpBinding"
                      name="mex"
                      contract="IMetadataExchange" />

            <host>

                </baseAddresses>
            </host>
        </service>
    </services>

WCF服务正在接收您的soap，但是它不能正确地解析wsdl2objc代理生成的soap头。这篇文章有一个你遇到的对实际问题有很好的描述。要确定所需的标头，首先创建一个成功调用服务的.NET WCF客户端。通过捕获它发送的soap，了解预期的头应该是什么。修改代理代码以生成作为.NET客户端的确切soap头。
