如何使用管理创建 WSO2 DAS 事件接收器 API

Question

在 carbon 配置文件中将 HideAdminServiceWSDLs 设置为 false 后，就可以发现 EventReceiverAdminService 服务端点。它公开 deployEventReceiverConfiguration 方法。谁能提供有关如何在多租户环境中使用此服务的示例？我尝试调用该服务，但每次收到以下响应：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <soapenv:Fault>
         <faultcode>soapenv:Server</faultcode>
         <faultstring>unknown</faultstring>
         <detail/>
      </soapenv:Fault>
   </soapenv:Body>
</soapenv:Envelope>

DAS 日志中没有有用的消息。

您需要提供事件接收器的 XML 配置。我用 SOAP UI 尝试了以下方法，它有效。

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:adm="http://admin.receiver.event.carbon.wso2.org">
   <soapenv:Header/>
   <soapenv:Body>
      <adm:deployEventReceiverConfiguration>
         <!--Optional:-->
         <adm:eventReceiverConfigXml><![CDATA[<eventReceiver xmlns="http://wso2.org/carbon/eventreceiver" name="httpReceiver" statistics="disable" trace="disable">
   <from eventAdapterType="http">
      <property name="transports">all</property>
   </from>
   <mapping customMapping="disable" type="json" />
   <to streamName="org.wso2.event.sensor.stream" version="1.0.0" />
</eventReceiver>]]>

在多租户环境中，使用各自租户管理员的凭据进行基本身份验证。然后它将在正确的租户中部署事件接收器。部署DAS时会打印如下日志，
