Question

我有一个简单的WCF服务起诉 SOAP 。我有一个非常简单的操作“GetMultiplied”，只有非常少量的数据。当客户端尝试调用该操作时，我得到以下异常。知道什么都可能是问题吗？

内部异常：{“远程服务器返回错误：（400）错误请求。”}

最后列出了完整的wsdl和架构。

注意：我已在服务和客户端配置中将配额值maxBufferSize等设置为更高的值。

追踪服务

当我在服务中使用跟踪时（基于How to turn on WCF tracing?），我得到以下内容 - 似乎没有记录错误。

<Type>3</Type>
<SubType Name="Information">0</SubType>
<Level>8</Level>

服务实施

public class CalculationService : ICalculationService
{

    public virtual GetMultipliedResponse GetMultiplied(GetMultipliedRequest request)
    {
        MultipliedResult result = new MultipliedResult();
        result.ResultNumber= ((request.InputNumber)*2);

        GetMultipliedResponse response = new GetMultipliedResponse(result);
        return response;
    }
}

客户端

    static void Main(string[] args)
    {
        CalculationServiceInterfaceClient proxy = new CalculationServiceInterfaceClient();
        multipliedResult result = proxy.getMultiplied(2);
    }

在自动生成的代码中，详细信息为：

    public NewClient.CalcReference.multipliedResult getMultiplied(int inputNumber) 
    {
        NewClient.CalcReference.getMultipliedRequest inValue = new NewClient.CalcReference.getMultipliedRequest();
        inValue.inputNumber = inputNumber;

        NewClient.CalcReference.getMultipliedResponse retVal = ((NewClient.CalcReference.CalculationServiceInterface)(this)).getMultiplied(inValue);
        return retVal.restaurants;
    }

Answer 1

我解决了问题:-)

我会为其他人的利益发布答案。

关键问题：我试图使用手动创建的wsdl。（我在服务中提到了本地副本 - 我正在使用工具从wsdl生成服务代码）。该服务没有提供。我应该尝试通过浏览svc文件来查看wsdl
使用 WcfTestClient 运行服务。发出一个错误，显示项目名称和我们使用的命名空间应该相同。（否则它将在命名空间名称之前附加项目名称，这将成为不正确的命名空间）

在“Visual Studio命令提示符”中键入“WcfTestClient”命令。 http://blogs.msdn.com/b/wcftoolsteamblog/archive/2010/01/04/tips-for-launching-wcf-test-client.aspx
通过浏览服务中的svc文件，显示元数据发布未启用。在web.config中添加了元数据浏览的服务行为。
服务的使用相对路径（而不是localhost）error "No protocol binding matches the given address ..."
服务跟踪也很有帮助（虽然这里没有帮助我）。使用“C：\ Program Files \ Microsoft SDKs \ Windows \ v7.0A \ bin \ SvcTraceViewer.exe”。在帖子后面，错误文件（initializeData =“Error.svclog”）存储在解决方案项目中。将其更改为其他位置不起作用。 How to turn on WCF tracing?
