.NET中的SOAP請求

Question

我們試圖使用SOAP請求與使用Visual Studio C＃的預訂API進行交互。

我們已經與另一個API的Web服務進行了接口而沒有問題，但是這個問題已證明存在問題。

我們已經將它作爲服務參考添加了，並且Visual Studio已經爲它和web.config項目生成了所有類，以便一切都很順利。

然而，當我們嘗試做一個簡單的請求，客戶端SOAP服務，我們得到以下錯誤：

Namespace='com.hrs.soap.hrs' is not supported with rpc\literal SOAP. The wrapper element has to be unqualified.

的代碼是：

PingRequest pingrequest = new PingRequest();  
SoapServiceClient service = new SoapServiceClient(); 
service.ping(pingrequest); 

這什麼在網站被添加。配置文件：

<system.serviceModel> 
    <bindings> 
     <basicHttpBinding> 
     <binding name="HRSSoapServiceBinding" closeTimeout="00:01:00" 
      openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 
      allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 
      maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" 
      messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 
      useDefaultWebProxy="true"> 
      <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" 
       maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 
      <security mode="None"> 
      <transport clientCredentialType="None" proxyCredentialType="None" 
       realm="" /> 
      <message clientCredentialType="UserName" algorithmSuite="Default" /> 
      </security> 
     </binding> 
     </basicHttpBinding> 
    </bindings> 
    <client> 
     <endpoint address="..." 
      binding="basicHttpBinding" bindingConfiguration="HRSSoapServiceBinding" 
      contract="HRSService.HRSSoapService" name="HRSSoapServicePort" /> 
    </client> 
    </system.serviceModel> 

根據文檔請求應該看起來像fo下面

<complexType name="PingRequest"> 
    <complexContent> 
     <extension base="tns:Request"> 
      <sequence> 
       <element name="echoData" type="xsd:string"/> 
      </sequence> 
     </extension> 
    </complexContent> 
</complexType>

我們安裝小提琴手，也沒有XML請求通過，我們可以看到，大概是因爲它發出任何事情之前拋出一個異常去。

我們需要在我們的設置中進行更改以完成此項工作？

UPDATE

繼我已經複製到本地的WSDL和所作的修訂davidfmatheson出色的意見，建議。我仍然得到在不同的地方同樣的錯誤，雖然可能：

[System.ComponentModel.EditorBrowsableAttribute(System.ComponentModel.EditorBrowsableState.Advanced)] 
     BLL.HRSService.pingResponse BLL.HRSService.HRSSoapService.ping(BLL.HRSService.pingRequest request) { 
      return base.Channel.ping(request); 
     } 

     public BLL.HRSService.HRSPingResponse ping(BLL.HRSService.HRSPingRequestWrapper ping1) { 
      BLL.HRSService.pingRequest inValue = new BLL.HRSService.pingRequest(); 
      inValue.ping = ping1; 
      BLL.HRSService.pingResponse retVal = ((BLL.HRSService.HRSSoapService)(this)).ping(inValue); 
      return retVal.pingResponse1; 
     } 

失敗是回base.Channel.ping（請求）線;，錯誤命名空間='com.hrs.soap.hrs'不受rpc \ literal SOAP支持。包裝元素必須是不合格的。

我也試圖明確設置SOAPBinding：

Exception Details: System.InvalidOperationException: Namespace='com.hrs.soap.hrs' is not supported with rpc\literal SOAP. The wrapper element has to be unqualified. 

Source Error: 

Line 15917:  [System.Web.Services.Protocols.SoapDocumentMethod(Use = System.Web.Services.Description.SoapBindingUse.Literal)]

Line 15919:   return base.Channel.ping(request); 
Line 15920:  } 
Line 15921: 

OK，現在我已經修改了SOAP綁定風格在我的本地WSDL記錄和重建的類和我有一個不同的錯誤：

Answer 1

您正在嘗試使用來自.NET的RPC字面服務，所以你可能需要的服務轉化爲文檔文字。請參閱MSDN Blog。

編輯：更完整的答案

我們的目標是能夠使用文檔文字，但仍發送相同的消息。我們來關注一下ping的操作。現在，您的WSDL已經類型定義爲：

<complexType name="HRSPingRequest"> 
    <complexContent> 
     <extension base="tns:HRSRequest"> 
      <sequence> 
       <element name="echoData" type="xsd:string"/> 
      </sequence> 
     </extension> 
    </complexContent> 
</complexType> 

和您的郵件定義爲：

<message name="HRSSoapService_pingRequest"> 
    <part name="pingRequest" type="tns:HRSPingRequest"/> 
</message> 

而且你的綁定定義爲：

<binding name="HRSSoapServiceBinding" type="tns:HRSSoapService"> 
    <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> 
    <operation name="ping"> 
     <soap:operation soapAction=""/> 
     <input> 
      <soap:body namespace="com.hrs.soap.hrs" use="literal"/> 
     </input> 
     <output> 
      <soap:body namespace="com.hrs.soap.hrs" use="literal"/> 
     </output> 
     <fault name="HRSException"> 
      <soap:fault name="HRSException" use="literal"/> 
     </fault> 
    </operation> 
</binding> 

所以在本地，我們改變「RPC 「to」document「，然後將WSDL修復爲實際文檔/文字：

<element name="ping" type="tns:HRSPingRequestWrapper" /> 
<complexType name="HRSPingRequestWrapper"> 
    <sequence> 
     <element name="pingRequest" type="tns:HRSPingRequest" /> 
    </sequence> 
</complexType> 
<complexType name="HRSPingRequest"> 
    <complexContent> 
     <extension base="tns:HRSRequest"> 
      <sequence> 
       <element name="echoData" type="xsd:string"/> 
      </sequence> 
     </extension> 
    </complexContent> 
</complexType> 

... 

<message name="HRSSoapService_pingRequest"> 
    <part name="pingRequest" element="tns:ping"/> 
</message> 

現在生成此WSDL並查看它是否發送ping請求。如果你沒有修復Response結構，它可能不知道返回的內容，但你至少應該看到通過線路發送的請求。您可以使用SoapUI加載這兩個WSDL並查看生成的請求類型。目標是發送相同的請求，只是使用文檔/文字而不是rpc/literal。
