問題描述

我在WSO2上為Lotus Domino Web Service創建了一個直通代理。 這是該服務的WSDL： 

    <?xml version="1.0" encoding="UTF-8"?>
   <definitions targetNamespace="urn:DefaultNamespace"
    xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:apachesoap="http://xml.apache.org/xml-soap"

            <element name="DODAJNAPIS">

                        <element name="WST1INPUT1" type="impl:WST1INPUT" />
                    </sequence>
                </complexType>
            </element>
            <complexType name="WST1INPUT">

                    <element name="INPUT2" nillable="true" type="xsd:string" />
                </sequence>
            </complexType>
            <element name="DODAJNAPISResponse">
                <complexType>
                    <sequence>
                        <element name="DODAJNAPISReturn" type="impl:WST1OUTPUT" />

                    <element name="OUTPUT2" nillable="true" type="xsd:string" />
                </sequence>
            </complexType>
        </schema>
    </wsdl:types>
    <message name="DODAJNAPISResponse">
        <part element="impl:DODAJNAPISResponse" name="parameters" />
    </message>
    <message name="DODAJNAPISRequest">

    </message>
    <portType name="WSO2ProviderClass">
        <operation name="DODAJNAPIS">
            <input message="impl:DODAJNAPISRequest" name="DODAJNAPISRequest" />
            <output message="impl:DODAJNAPISResponse" name="DODAJNAPISResponse" />
        </operation>
    </portType>
    <binding name="DominoSoapBinding" type="impl:WSO2ProviderClass">
        <wsdlsoap:binding style="document"
            transport="http://schemas.xmlsoap.org/soap/http" />
        <operation name="DODAJNAPIS">
            <wsdlsoap:operation soapAction="DODAJNAPIS" />
            <input name="DODAJNAPISRequest">
                <wsdlsoap:body use="literal" />
            </input>
            <output name="DODAJNAPISResponse">
                <wsdlsoap:body use="literal" />
            </output>
        </operation>
    </binding>
    <service name="WSO2ProviderClassService">
        <port binding="impl:DominoSoapBinding" name="Domino">
            <wsdlsoap:address
                location="http://firmaa.mis.eu:80/firmaa/b2b/finanse.nsf/WST1?OpenWebService" />
        </port>
    </service>
</definitions>

此代理的WSO2源視圖： 

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
       name="WSO2DominoWrappedTest"
       transports="https,http"
       statistics="disable"
       trace="enable"
       startOnLoad="true">
   <target>
      <outSequence>
         <send/>
      </outSequence>
      <endpoint>
         <address uri="http://firmaa.mis.eu/firmaa/b2b/finanse.nsf/WST1?OpenWebService"/>
      </endpoint>
   </target>
   <publishWSDL uri="http://firmaa.mis.eu/firmaa/b2b/finanse.nsf/WST1?WSDL"/>
   <description/>
</proxy>

問題是當我嘗試進行測試時（通過WSO2測試面板（tryit））。 測試信息： 

<body>
   <p:DODAJNAPIS xmlns:p="urn:DefaultNamespace">
      <!--Exactly 1 occurrence-->
      <WST1INPUT1>
         <!--Exactly 1 occurrence-->
         <INPUT1>ABC</INPUT1>
         <!--Exactly 1 occurrence-->
         <INPUT2>DEF</INPUT2>
      </WST1INPUT1>
   </p:DODAJNAPIS>
</body>

使用HttpSoap12Endpoint的響應是： 

<TryitProxyError xmlns:h="http://wso2.org/ns/TryitProxy" h:status="SOAP envelope error">org.apache.axis2.AxisFault: 
Transport level information does not match with SOAP Message namespace URI</TryitProxyError>

使用HttpSoap11Endpoint，響應為： 

<soapenv:Fault xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <faultcode>soapenv:Server.generalException</faultcode>
   <faultstring>org.xml.sax.SAXParseException: Premature end of file.</faultstring>
   <detail/>
</soapenv:Fault>

中介消息跟蹤程序為我提供了此功能： 

07:46:13,071 [-] [PassThroughMessageProcessor-46] INFO Proxy Service WSO2DominoWrappedTest received a new message from : 192.168.7.247

07:46:13,133 [-] [PassThroughMessageProcessor-48] INFO End : Sequence <anonymous>

在WSO2服務器控制台上，我得到以下信息： 

[2015-05-13 07:40:21,024]  WARN - TargetHandler http-outgoing-128: Receiving res
ponse while the handler is in an inconsistent state REQUEST_READY
[2015-05-13 07:40:21,024] ERROR - TargetHandler Unexpected error.

ponse for the request with message Id : urn:uuid:b1275096-2ad4-4d2d-92f4-cca5499
027c8 But a callback is not registered (anymore) to process this response

我注意到沒有任何請求發送到Domino WebService（我根據請求記錄輸入值，並且該記錄為空）。

我不知道問題出在哪里，以及如何解決它才能使它正常工作...您知道如何處理嗎？

4 個解決方案

解決方案1
 1 已采納  2015-05-13 09:42:34

解決了。 我用inSequence中的屬性創建了自定義代理（不是Passthrough！）： 

<inSequence>
         <property name="FORCE_HTTP_1.0" value="true" scope="axis2"/>
      </inSequence>

然后一切正常：)

解決方案2

請檢查在Firmaa / b2b / finanse.nsf的ACL中允許匿名用戶時，該功能是否有效。 然后，您需要解決身份驗證問題。

進一步研究WSDL，我認為WS在Domino服務器上被定義為LITERATE格式，請訪問http://www.ibm.com/developerworks/lotus/library/nd7-webservices/將其更改為RPC /編碼。

解決方案3

Domino Web Service無需任何身份驗證即可訪問（在SOAPUI中，我可以對其進行測試而不會出現問題）。 我嘗試使用RPC /編碼的wsdl： 

<?xml version="1.0" encoding="UTF-8"?>

        <operation name="DODAJNAPIS">
            <wsdlsoap:operation soapAction="DODAJNAPIS" />
            <input name="DODAJNAPISRequest">
                <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
                    namespace="urn:DefaultNamespace" use="encoded" />
            </input>
            <output name="DODAJNAPISResponse">
                <wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"

            </output>
        </operation>
    </binding>
    <service name="WSO2ProviderClassService">
        <port binding="impl:DominoSoapBinding" name="Domino">

        </port>
    </service>
</definitions>

但得到相同的SAXParserException：文件的結尾過早。 在WSO2控制台上，警告和錯誤與以前相同。

我為此Domino Web Service編寫了一些Java“包裝器”服務。 我發現，我必須設定 

options.setProperty(HTTPConstants.CHUNKED, "false");

使這個包裝器正常工作。 在獲得相同的SAXParserException之前。 是否有任何WSO2屬性將HTTPConstants.CHUNKED設置為false？
