wso2 ESB：克隆和聚合超時

Question

我嘗試在WSO2 ESB中使用代理和API來測試類似SOAP Web服務的聚合到一個響應中，但我只是有超時。爲了進行測試，我使用了Weather Web服務（http://wsf.cdyne.com/WeatherWS/Weather.asmx?wsdl）。我基本上通過使用克隆介質調用GetCityWeatherByZIP兩次相同的操作，爲每個ZIP代碼提供不同的郵政編碼，然後彙總結果。最終目的是調用託管在不同服務器上的Web服務，但目前我正嘗試使用相同的服務。我將不勝感激任何幫助。

下面是代理配置：

<?xml version="1.0" encoding="UTF-8"?> 
    <proxy xmlns="http://ws.apache.org/ns/synapse" 
     name="aggre" 
     transports="http" 
     statistics="disable" 
     trace="enable" 
     startOnLoad="true"> 
     <target> 
     <inSequence> 
     <clone> 
      <target> 
       <sequence> 
        <payloadFactory media-type="xml"> 
        <format> 
         <m0:GetCityWeatherByZIP xmlns:m0="http://ws.cdyne.com/WeatherWS/"> 
          <m0:ZIP>11001</m0:ZIP> 
         </m0:GetCityWeatherByZIP> 
        </format> 
        <args/> 
        </payloadFactory> 
        <header name="Action" scope="default" value="urn:GetCityWeatherByZIP "/> 
        <call> 
        <endpoint key="weather"/> 
        </call> 
       </sequence> 
      </target> 
      <target> 
       <sequence> 
        <payloadFactory media-type="xml"> 
        <format> 
         <m0:GetCityWeatherByZIP xmlns:m0="http://ws.cdyne.com/WeatherWS/"> 
          <m0:ZIP>11010</m0:ZIP> 
         </m0:GetCityWeatherByZIP> 
        </format> 
        <args/> 
        </payloadFactory> 
        <header name="Action" scope="default" value="urn:GetCityWeatherByZIP "/> 
        <call> 
        <endpoint key="weather"/> 
        </call> 
       </sequence> 
      </target> 
     </clone> 
     <aggregate> 
      <completeCondition> 
       <messageCount min="-1" max="-1"/> 
      </completeCondition> 
      <onComplete xmlns:m0="http://ws.cdyne.com/WeatherWS" 
         expression="/m0:GetCityWeatherByZIPResponse"> 
       <drop/> 
      </onComplete> 
     </aggregate> 
     </inSequence> 
     <outSequence> 
     <send/> 
     </outSequence> 
     </target> 
     <description/> 
    </proxy> 

下面天氣端點配置：

<endpoint xmlns="http://ws.apache.org/ns/synapse" name="weather"> 
    <address uri="http://wsf.cdyne.com/WeatherWS/Weather.asmx" format="soap11"> 
     <suspendOnFailure> 
     <progressionFactor>1.0</progressionFactor> 
     </suspendOnFailure> 
     <markForSuspension> 
     <retriesBeforeSuspension>0</retriesBeforeSuspension> 
     <retryDelay>0</retryDelay> 
     </markForSuspension> 
    </address> 
</endpoint>

Answer 1

SOAP動作不正確，必須http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP

命名空間聚集的的onComplete XPath表達式是不正確，一個「/」是在最後丟失：http://ws.cdyne.com/WeatherWS/

聚集之後，你就不想放棄的消息，你想送它作爲響應：在「的onComplete」調解

與<send/>取代<drop/>的響應將是如OAP消息和SOAP體必須有一個根節點作爲第一個孩子，所以你必須應用改造，爭取爲例：

<payloadFactory media-type="xml"> 
    <format> 
    <response> 
     $1 
    </response> 
    </format> 
    <args> 
    <arg evaluator="xml" xmlns:m0="http://ws.cdyne.com/WeatherWS/" expression="//m0:GetCityWeatherByZIPResponse"/> 
    </args> 
</payloadFactory> 

默認情況下，克隆調解停止父母調解，你需要指定continueParent="true"，如果你想聚合要執行

使用呼叫調停，強調工作線程的回報，而不必等待迴應：執行總調解人，測試，如果消息是GetCityWeatherByZIPResponse

完成前：用於執行代理將達到你的總要求代理：

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

     <filter source="local-name($body/*[1])" regex="GetCityWeatherByZIPResponse">

端點：

<?xml version="1.0" encoding="UTF-8"?> 
<endpoint xmlns="http://ws.apache.org/ns/synapse" name="weather"> 
    <wsdl service="Weather" 
     port="WeatherSoap"

</endpoint> 

的響應，我得到：

Answer 2

呼叫中介依靠無阻塞傳輸：編輯repository/conf/nhttp.properties並添加 http.socket.timeout.sender = 60000，如果你同意等待60秒
