本文介绍了400错误请求例外：数据量小的简单的SOAP WCF服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个简单的WCF服务起诉的 SOAP 。我有一个非常简单的操作GetMultiplied的数据量非常小。我得到以下异常时，客户端尝试调用操作。 ？任何想法都可能成为问题。




内部异常：{远程服务器返回错误：（400）错误的请求。 }




完整的WSDL和架构在年底上市。



请注意：我已经设置配额值，MAXBUFFERSIZE等在两个服务端和客户端的配置较高的值



跟踪在服务



当我在使用跟踪服务（基于如何？打开WCF跟踪），我得到了以下 - 好像是没有记录的错误

解决方案

我的问题解决了:-)



我将公布为他人的利益，答案




  1. 关键问题：我试图用手动创建的WSDL。 （我下文称本地副本里面提供服务 - 我使用的工具来生成从WSDL服务代码）。该服务没有提供它。我应该尝试从浏览SVC文件来查看WSDL


  2. 使用的 WcfTestClient 冉服务。给了显露在项目名称，我们使用应该是相同的命名空间中的错误。 （否则将追加命名空间名称前的项目名称，这将成为不正确的命名空间）



    在Visual Studio命令提示符中的WcfTestClient命令。 的http：/ /blogs.msdn.com/b/wcftoolsteamblog/archive/2010/01/04/tips-for-launching-wcf-test-client.aspx


  3. 通过用户在服务的SVC文件，它表明，在元数据发布未启用。增加了在web.config元数据浏览的服务行为


  4. 有关服务（而不是本地主机）的error [否协议绑定指定的地址匹配..."


  5. 服务跟踪也有帮助（虽然并没有帮助我在这里）。使用C：\Program Files\Microsoft SDKs\Windows\v7.0A\bin\SvcTraceViewer.exe。其次岗位和错误文件（initializeData =Error.svclog）存储解决方案项目中。它更改到其他地点没有工作。 如何打开WCF跟踪？


  6. 请参照的一个WCF服务 - 两个客户端;一个客户端不能正常工作



I have a simple WCF service suing SOAP. I have a very simple operation "GetMultiplied " with very small amount of data. I am getting following exception when client try to call the operation. Any idea what all could be the issues?

Inner Exception: {"The remote server returned an error: (400) Bad Request."}

Complete wsdl and schema is listed at the end.

Note: I have set quota values, maxBufferSize etc to higher values in both service and client config.

Tracing in Service

When I used tracing in service (based on How to turn on WCF Tracing?), I am getting the following - seems like there is no error logged.

<Type>3</Type>
<SubType Name="Information">0</SubType>
<Level>8</Level>
<TimeCreated SystemTime="2012-09-13T17:05:17.6059181Z" />
<Source Name="System.ServiceModel" />
<Description>AppDomain unloading.</Description>

Service implementation

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;
    }
}

Client

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

In the auto generated code the detail is:

    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;
    }

解决方案

I solved the problem :-)

I will publish the answer for the benefit of others.

  1. Key problem: I was trying to use the manually created wsdl. (I reffered the local copy available inside service - I was using a tool to generate the service code from wsdl). The service was not providing it. I should have tried to view the wsdl from browsing the svc file

  2. Ran the service using WcfTestClient. Gave an error that revealed the project name and the namespace that we use should be same. (Otherwise it will append the project name before the namespace name and that will become incorrect namespace)

    Type the "WcfTestClient" command in "Visual Studio Command Prompt". http://blogs.msdn.com/b/wcftoolsteamblog/archive/2010/01/04/tips-for-launching-wcf-test-client.aspx

  3. By browsing the svc file in the service, it showed that the metadata publishing is not enabled. Added a service behavior for meta data browsing in the web.config.

  4. Used relative path for the service (instead of localhost) error "No protocol binding matches the given address ..."

  5. Service Tracing also can be helpful (though did not help me here). Used "C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\SvcTraceViewer.exe". Followed the post and the Error file (initializeData="Error.svclog") is stored inside the solution project. Changing it to other locations did not work. How to turn on WCF Tracing?

  6. Refer One WCF service – two clients; One client does not work
