【问题描述】：

有时我在使用 HTTP 组件连接到 Eloqua 系统时遇到错误。有时它会正确地从 Eloqua 获取数据，但在极少数情况下会出现以下错误。

20:31:11.474     08/18/2017     Worker-0     [elq-sfdc-batch-interface-v1].ma-sfdc-ma-batch-interfaceFlow.stage1.29     ERROR
Remote host closed connection. Possible SSL/TLS handshake issue. Check protocols, cipher suites and certificate set up. Use -Djavax.net.debug=handshake for further debugging.

这就是 HTTP 组件的配置方式

<http:request-config name="Eloqua_BULK_API" protocol="HTTPS" host="${eloqua.host}" port="${eloqua.port}" basePath="/API/BULK/2.0" connectionIdleTimeout="1200000" responseTimeout="1200000" doc:name="HTTP Request Configuration">
    <http:basic-authentication username="${eloqua.username}" password="${eloqua.password}" preemptive="true"/>
</http:request-config>

<http:request config-ref="Eloqua_BULK_API" path="#[flowVars.'uri-export-data-contact']" method="GET" doc:name="Get All Exported Data">
    <http:request-builder>
        <http:query-param paramName="limit" value="${eloqua.record.limit.activities}"/>
        <http:query-param paramName="offset" value="#[sessionVars.offset]"/>
    </http:request-builder>
</http:request>

我在连接到 Salesforce 时遇到了类似的异常，在 Salesforce 中，我启用了随时连接选项。 HTTP 组件中是否有相同的选项？

我找到了解决方案，它一直有效，直到成功，下面是代码

<until-successful maxRetries="20" millisBetweenRetries="40000" synchronous="true" doc:name="Until Successful">
    <processor-chain doc:name="Processor Chain">
        <http:request config-ref="Eloqua_BULK_API" path="#[flowVars.'uri-export-data-contact']" method="GET" doc:name="Get All Exported Data">
            <http:request-builder>
                <http:query-param paramName="limit" value="${eloqua.record.limit.activities}"/>
                <http:query-param paramName="offset" value="#[sessionVars.offset]"/>
            </http:request-builder>
        </http:request>
    </processor-chain>
</until-successful>
