WCFリモートサーバーが予期しない応答を返しました：（400）不正な要求

Question

私はbasicHttpBindingプロトコルをWCFに使用しています。

大きいClass<T>（問題ありません）が届きます。

しかし、私はClass<T>は私が

例外がスローされ、このエラーが出る大送る： 'System.ServiceModel.ProtocolException' を にSystem.ServiceModel.Internals.dll

追加情報：リモートサーバーが返さ予想外の レスポンス：（400）Bad Request。

私のクライアントコードは、あなたの定義されたbasicHttpBindingを割り当てることはありませんので、あなたはあなたのサービスに大きなオブジェクトを送信することができない理由がある

public static EndpointAddress EndPoint = new EndpointAddress("http://192.168.1.102:9159/DeltaService1.svc"); 

public static BasicHttpBinding CreateBasicHttp() 
{ 

    var binding = new BasicHttpBinding(); 
    binding.MaxReceivedMessageSize = 2147483647; 
    binding.MessageEncoding = WSMessageEncoding.Text; 
    binding.ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas() 
    { 
     MaxArrayLength = 2147483647, 
     MaxStringContentLength = 2147483647, 
     MaxBytesPerRead = 2147483647, 
     MaxDepth = 2147483647, 
     MaxNameTableCharCount = 2147483647, 
    }; 
    binding.MaxBufferPoolSize = 2147483647; 
    binding.MaxBufferSize = 2147483647; 
    binding.TransferMode = TransferMode.Streamed; 
    binding.Security = new BasicHttpSecurity(); 

    binding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName; 

    binding.Security.Mode = BasicHttpSecurityMode.None; 
    binding.Security.Transport = new HttpTransportSecurity(); 
    binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None; 
    binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None; 
    binding.Security.Transport.Realm = ""; 

    var timeout = new TimeSpan(1, 1, 0); 
    binding.SendTimeout = timeout; 

    binding.CloseTimeout = timeout; 
    binding.OpenTimeout = timeout; 
    binding.ReceiveTimeout = timeout; 
    binding.SendTimeout = timeout; 
    binding.TextEncoding = Encoding.UTF8; 

    ChannelFactory<IDeltaService1> factory = new ChannelFactory<IDeltaService1>(binding, EndPoint); 

    foreach (OperationDescription op in factory.Endpoint.Contract.Operations) 
    { 
     var dataContractBehavior = op.Behaviors.Find<DataContractSerializerOperationBehavior>(); 
     if (dataContractBehavior != null) 
     { 
      dataContractBehavior.IgnoreExtensionDataObject = true; 
      dataContractBehavior.MaxItemsInObjectGraph = int.MaxValue; 
     } 
    } 

    IDeltaService1 channel = factory.CreateChannel(); 

    return binding; 
}

ですサービスエンドポイント

<bindings> 
    <basicHttpBinding> 
    <binding name="NewBinding0"..... 

しかし、あなたはエンドポイントを定義するときに、あなたはそれに "NewBinding0" を割り当てないでください：あなたのサービスのconfigで

、あなたが持っている

<endpoint behaviorConfiguration="myHttpBindingEndPointBihaviour" 
     binding="basicHttpBinding" bindingConfiguration="".... 

以来bindingConfiguration要素のdoesnバインド設定を指定しないと、basicHttpBindingのデフォルト値が使用されます。そのため、大きなオブジェクトを送信することができません。

は、このようなbindingConfiguration属性を経由して、あなたのエンドポイントに「NewBinding0」を割り当てます。

<endpoint behaviorConfiguration="myHttpBindingEndPointBihaviour" 
     binding="basicHttpBinding" bindingConfiguration="NewBinding0"..... 

そして、あなたのサービスは、クライアントが送信したときに、より大きなオブジェクトを受け取ることができるはずです。
