远程服务器返回意外响应:(400) 错误请求

本文关键字:错误 请求 响应 服务器 返回 意外 | 更新日期: 2023-09-27 17:56:16

我收到此错误"远程服务器返回意外响应:(400) 错误请求。即使在堆栈溢出中,我也查看了很多线程并尝试了这些解决方案,但它们对我不起作用......比如增加超时和缓冲区大小。

这是我在服务器上的代码。

 protected override System.ServiceModel.ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
    {
        BasicHttpBinding basichttpbinding = new BasicHttpBinding(BasicHttpSecurityMode.None);
        basichttpbinding.CloseTimeout=TimeSpan.MaxValue;
        basichttpbinding.OpenTimeout=TimeSpan.MaxValue;
        basichttpbinding.ReceiveTimeout=TimeSpan.MaxValue;
        basichttpbinding.SendTimeout=TimeSpan.MaxValue;
       // basichttpbinding.TransferMode = TransferMode.Buffered;
        ServiceEndpoint servicepoint=new ServiceEndpoint(ContractDescription.GetContract(serviceType));
         servicepoint.Binding=basichttpbinding;
        ServiceHost servicehost = new ServiceHost(serviceType, baseAddresses);
        ((ServiceDebugBehavior)servicehost.Description.Behaviors[typeof(ServiceDebugBehavior)]).IncludeExceptionDetailInFaults=true;
        servicehost.OpenTimeout = TimeSpan.MaxValue;
        servicehost.CloseTimeout = TimeSpan.MaxValue;
        servicepoint.Binding.SendTimeout = TimeSpan.MaxValue;
        servicepoint.Binding.ReceiveTimeout = TimeSpan.MaxValue;
        basichttpbinding.MaxBufferPoolSize = 999999999;
       // basichttpbinding.MaxConnections = 999999999;
        //basichttpbinding.MaxConnections = 999999999;
        basichttpbinding.MaxReceivedMessageSize = 999999999;
        XmlDictionaryReaderQuotas quotas = new XmlDictionaryReaderQuotas();
        quotas.MaxArrayLength = 999999999;
        quotas.MaxBytesPerRead = 999999999;
        quotas.MaxDepth = 999999999;
        quotas.MaxNameTableCharCount = 999999999;
        quotas.MaxStringContentLength = 999999999;
        basichttpbinding.ReaderQuotas = quotas;
        //foreach (Uri uri in baseAddresses)
        //{
        servicehost.AddServiceEndpoint(typeof(IService), basichttpbinding, "");
       // }
        return servicehost;
    }

这是我在客户端上使用的代码。

 static void Main(string[] args)
        {
            BasicHttpBinding basichttpbinding = new BasicHttpBinding(BasicHttpSecurityMode.None);
            ServiceEndpoint endpoint=new ServiceEndpoint(ContractDescription.GetContract(typeof(IService)));
            endpoint.Binding=basichttpbinding;

            basichttpbinding.CloseTimeout = TimeSpan.MaxValue;
            basichttpbinding.OpenTimeout = TimeSpan.MaxValue;
            basichttpbinding.ReceiveTimeout = TimeSpan.MaxValue;
            basichttpbinding.SendTimeout = TimeSpan.MaxValue;
            basichttpbinding.TransferMode = TransferMode.Streamed;

            endpoint.Binding.SendTimeout = TimeSpan.MaxValue;
            endpoint.Binding.ReceiveTimeout = TimeSpan.MaxValue;
            basichttpbinding.MaxBufferPoolSize = 999999999;
           // basichttpbinding.MaxConnections = 999999999;
            //basichttpbinding.MaxConnections = 999999999;
            basichttpbinding.MaxReceivedMessageSize = 999999999;
            XmlDictionaryReaderQuotas quotas = new XmlDictionaryReaderQuotas();
            quotas.MaxArrayLength = 999999999;
            quotas.MaxBytesPerRead = 999999999;
            quotas.MaxDepth = 999999999;
            quotas.MaxNameTableCharCount = 999999999;
            quotas.MaxStringContentLength = 999999999;
            basichttpbinding.ReaderQuotas = quotas;


         EndpointAddress address=new EndpointAddress("http://localhost:52855/WCFService1/Service.svc");
         ChannelFactory<IService> objClient = new ChannelFactory<IService>(basichttpbinding,address);

         IService obj =   objClient.CreateChannel(address);
         obj.GetData(1);
        }

请帮助我..谢谢。。

编辑:请不要说"使用配置文件"等。我这样做只是因为我别无选择,必须这样做。谢谢

编辑:追踪后更详细的信息...

远程服务器返回意外响应:(400) 错误请求

从您发布的代码来看,鉴于 URI 中的 .svc 扩展名,您的客户端似乎希望与 IIS 承载的服务进行交互:

EndpointAddress address=new EndpointAddress("http://localhost:52855/WCFService1/Service.svc");

你没有说明你的服务是 IIS 承载的还是自承载的,但你确实说配置文件不是一个选项。 我看到两种方法可以解决您遇到的问题:

IIS 托管

  1. 若要在 IIS 下以编程方式配置服务主机,需要:

    a. 实现从 ServiceHost 和 ServiceHostFactory 派生的自己的类。

    b. 将代码内联放入 .svc 文件中。

  2. 如果选择实现自己的派生 ServiceHost 和 ServiceHostFactory 类,则需要在 .svc 文件的 @ServiceHost 标记中指定 ServiceHostFactory派生类。

自托管

  1. 在服务器代码中,为 AddServiceEndpoint 方法调用中的每个终结点指定一个 URI。
  2. 在客户端代码中,在创建通道时将相同的 URI 传递给 ChannelFactory。
  3. 在这种情况下,您将没有 .svc 文件。
  4. 完成后,不要忘记
  5. 关闭客户端上的代理 - 尤其是在使用 IIS 时。

我希望这有助于您指明正确的方向。 如果您需要更多信息,请询问。
