在Soap XML信封中發送「XML數據作爲字符串」

我有需要接收XML字符串的WCF Soap Web服務。儘管我對webservices的使用經驗不多，但我仍然嘗試過。這個webservice應該是從SAP PI調用的。在Soap XML信封中發送「XML數據作爲字符串」

請求消息的結構是如下所示：

public class DtoRequest<T> : IDtoRequest where T : class 
{ 
    public InteractionContext Context { get; set; } 
    public T Request { get; set; } 
}

其中類型是一個類的以下

public class SendRfqRequest : DtoRequest<ImportRfqDataDto> 
{ 
} 

[DataContract] 
public class ImportRfqDataDto 
{ 
    [DataMember] 
    public string RfqXmlData { get; set; } 
}

的InteractionContext採用以下字段：

public class InteractionContext 
{ 
    public string Application { get; set; } 
    public string License { get; set; } 
    public DateTime TimeStamp { get; set; } 
    public Guid Id { get; set; } 
}

我在webservicesdev服務器上部署了該代碼，生成的代碼將其與wsdl.exe一起使用nd使用簡單的控制檯應用程序對其進行測試：

// Generated from wsdl.exe tool 
RfqImportServiceClient client = new RfqImportServiceClient(); 
// Xml Document 
XDocument rfqXml = XDocument.Load("..\\..\\RfqValidGood.xml"); 

SendRfqRequest request = new SendRfqRequest 
{ 
    Context = new CityOfCapeTown.Services.Common.InteractionContext 
    { 
     Id = Guid.NewGuid(), 
     Application = "TestApplication", 
     License = "TestLicenseKey", 
     TimeStamp = DateTime.Now, 
    }, 
    Request = new DataTransferObjects.ImportRfqDataDto 
    { 
     RfqXmlData = rfqXml.ToString() 
    } 
}; 

Console.WriteLine("\n\n- Attempting connection to web-service"); 
SendRfqResponse response = client.ProcessRfq(request); 
Console.WriteLine("- Successfully connected to web-service"); 
Console.WriteLine("- Status of response: " + (ResponseType)response.Result);

這一切都很完美。從SAP PI測試Web服務時出現問題。當XML數據在RfqXmlData標記中傳遞時，會出現問題。我試着在SOAP UI中測試它。它產生從WSDL以下SOAP信封：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:tem="http://tempuri.org/" xmlns:cit="http://schemas.datacontract.org/2004/07/CityOfCapeTown.Services.Common" xmlns:proc="http://schemas.datacontract.org/2004/07/ProcurementAdministrationPortal.WebService.DataTransferObjects"> 
    <soapenv:Header/> 
    <soapenv:Body> 
     <tem:ProcessRfq> 
     <!--Optional:--> 
     <tem:request> 
      <!--Optional:--> 
      <cit:Context> 
       <!--Optional:--> 
       <cit:Application>SAPClient</cit:Application> 
       <!--Optional:--> 
       <cit:Id>1a975cab-bc7c-47e3-aa77-ac9dc407721d</cit:Id> 
       <!--Optional:--> 
       <cit:License>1a975cab-bc7c-47e3-aa77-ac9dc407721d</cit:License> 
       <!--Optional:--> 
       <cit:TimeStamp>2014-01-01</cit:TimeStamp> 
      </cit:Context> 
      <!--Optional:--> 
      <cit:Request> 
       <!--Optional:--> 
       <proc:RfqXmlData> 
       xmldata 
       </proc:RfqXmlData> 
      </cit:Request> 
     </tem:request> 
     </tem:ProcessRfq> 
    </soapenv:Body> 
</soapenv:Envelope>

通過一些隨機字符串中的標籤時，該工作在SOAP UI：

<proc:RfqXmlData> 
    random string 
</proc:RfqXmlData>

傳遞所需的XML數據時，卻給出了一個錯誤：

<proc:RfqXmlData> 
    <Rfq><IsAbove30k>true</IsAbove30k><ReferenceNumber>ReferenceNumber1</ReferenceNumber><ContactPersonName>ContactPersonName1</ContactPersonName><ContactPersonTelephoneNumber>ContactPersonTe1</ContactPersonTelephoneNumber><ContactPersonCellPhone>ContactPersonCe1</ContactPersonCellPhone><BuyerName>BuyerName1</BuyerName><BuyerTelephoneNumber>BuyerTelephoneN111111111111111111111</BuyerTelephoneNumber><BuyerEmailAddress>BuyerEmailAddress1</BuyerEmailAddress><ProcurementItem><Title>Title111111111111111111111111</Title><ClosingDate>1900-01-01T01:01:01+02:00</ClosingDate><Description>Description11111111111111111</Description><CaptureDate>1900-01-01T01:01:01+02:00</CaptureDate></ProcurementItem><RfqGood><DeliveryTo>DeliveryTo1</DeliveryTo><DeliveryAddress>DeliveryAddress1</DeliveryAddress><DeliverySuburb>DeliverySuburb1</DeliverySuburb><DeliveryPostalCode>1</DeliveryPostalCode><SubmissionFax>SubmissionFax1</SubmissionFax><Specification>Specification1</Specification><SubmissionFax2>SubmissionFax21</SubmissionFax2><DeliveryDate>1900-01-01T01:01:01+02:00</DeliveryDate><Good>Tools &amp; Machinery</Good></RfqGood></Rfq> 
</proc:RfqXmlData>

錯誤：

<faultstring xml:lang="en-ZA">The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:request. The InnerException message was 'There was an error deserializing the object of type ProcurementAdministrationPortal.WebService.Messages.SendRfqRequest. End element 'RfqXmlData' from namespace 'http://schemas.datacontract.org/2004/07/ProcurementAdministrationPortal.WebService.DataTransferObjects' expected. Found element 'Rfq' from namespace ''. Line 22, position 10.'. Please see InnerException for more details.</faultstring>

它看起來像它試圖反序列化<Rfq>...</Rfq>。在我看來，我必須做的是讓服務將XML數據看作字符串而不是XML。不過，我仍然需要它成爲XML的另一端。

你可以試試來包裝xml內容 – Anand 2014-11-21 11:32:33

@Anand：是的。正是我所期待的。 – Carel 2014-11-21 11:46:09

將這段XML包裝在<![CDATA[]]>標記中。

「 CDATA stands for Character Data and it means that the data in between these tags includes data that could be interpreted as XML markup, but should not be.」
