帶默認空標籤的WCF請求

Question

我試圖使用TLS連接到SOAP 1.1 Web服務。 證書已設置正確，並且可以與Web服務進行通信。但是，當我嘗試使用純C＃項目來執行此操作時，使用由VS2010生成的代理類，請求似乎是不完整的，因爲空標記不在請求中。然後我得到一個「這是一個操作實現產生故障」故障，在提琴手

如果我再嘗試推出使用了SoapUI請求可見，我從一個web服務響應成功的。

我使用Fiddler來比較這兩個請求，並且我注意到C＃請求很簡單，只發送填充在我的C＃類中的元素。 但是，當我檢查了SoapUI請求，該請求包含在WSDL/XSD的定義每一個元素，即使它們是空的。

我想了解如何配置C＃客戶端以包含空元素，以查看web服務是否會接受我的請求，但是我無法找到這樣的設置。

C＃的請求響應：

正如你所看到的，soapUI的要求是更爲完整即使這些元素是空的。

C＃代碼（重要部件）：

_binding = new BasicHttpBinding(BasicHttpSecurityMode.Transport); 
_binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate; 

_endpoint = new EndpointAddress(endpointAddress + "xxx"); 

_proxy = new ContractCancellationPortTypeClient(_binding, _endpoint); 
_proxy.ClientCredentials.ClientCertificate.SetCertificate(
     StoreLocation.LocalMachine, 
     StoreName.My, 
     X509FindType.FindBySubjectName, 
     "xxx"); 
_proxy.ContractCancellation(new ContractCancellationRequestEnvelope() 
     { Portaal_Content = new ContractCancellationRequestEnvelope_PC() 
      { Portaal_MeteringPoint = new ContractCancellationRequestEnvelope_PC_PMP() 
       { EANID = request.EanId, 
       MPCommercialCharacteristics = new ContractCancellationRequestEnvelope_PC_PMP_MPCC() 
        { ContractCancellationDate = request.ContractCancellationDate }, 
       Portaal_Mutation = new ContractCancellationRequestEnvelope_PC_PMP_PM() 
        { Initiator = request.SupplierEanId, 
        Dossier = new ContractCancellationRequestEnvelope_PC_PMP_PM_Dossier() 
         { ID = "TST0000001" } 
        } 
       } 
      }); 

Answer 1

在代碼中，你產生ContractCancellationRequestEnvelope的Portaal_Content部分，但不是BusinessDocumentHeader部分。

如果你看看收到的故障（通過C＃）我敢打賭，有一個在BusinessDocumentHeader部分中的一個或多個必需的元素缺失：

錯誤文本是XML schema validation error，並且錯誤細節是：

ContractCancellationRequestEnvelope[1]/part1[1]/ContractCancellationRequestEnvelope[1]/BusinessDocumentHeader[1]/Destination[1]

你需要確保所有必需的元素存在於你的SOAP消息。

編輯

像這樣的東西應該做的伎倆：

ContractCancellationRequestEnvelope reqMsg = new ContractCancellationRequestEnvelope(); 

reqMsg.BusinessDocumentHeader = new BusinessDocumentHeader() 
    { CorrelationTimestamp = "?", 
     MessageID = "?" }; 
reqMsg.BusinessDocumentHeader.Destination = new Destination(); 
reqMsg.BusinessDocumentHeader.Receiver = new Receiver() 
    { ReceiverID = "?" }; 

等。基本上，確保您創建所需的每個元素。

順便說一句，你可以做嵌套自動初始化（如在您發佈的代碼），我只是採取了更加明確的路線在我的例子提高可讀性。

該服務的WSDL將告訴你什麼是必需的或可選的。
