Question

我从salesforce联系对象查询数据（10 - 20条记录），并且我需要将id值捕获到变量中。为此，我将有效负载设置为＃[org.apache.commons.collections.IteratorUtils.toList（payload）]但不起作用。

PFB是示例代码：

<flow name="SetFunctionRole-table">
        <sfdc:query config-ref="SFA_NOL_CLOUDHUB2" query="dsql:SELECT Id, AccountId,Account_BP_ID__c,Account_BT_Code__c,Birthdate,Department,Email,Fax,FirstName,LastName,MiddleName,MobilePhone,Name FROM Contact WHERE AccountId = '#[flowVars.varCustomer_Id]' ORDER BY AccountId ASC" doc:name="get contacts from AccountId"/>
        <logger message="#[payload]" level="INFO" doc:name="Logger"/>
        <set-payload value="#[org.apache.commons.collections.IteratorUtils.toList(payload)]" doc:name="Set Payload"/>
        <foreach collection="#[payload]" doc:name="For Each">
            <logger message="#[payload]" level="INFO" doc:name="Logger"/>
            <set-variable variableName="varContact_id" value="#[payload['Id']]" doc:name="Variable"/>
            <sfdc:query-single config-ref="SFA_NOL_CLOUDHUB2" query="dsql:SELECT Function__c,Id FROM Contact_Function_Role__c WHERE Contact__c = '#[flowVars.varContact_id]'" doc:name="Salesforce"/>
            <logger message="#['Inserting key:' + flowVars.varContact_id + ' and value: ' + payload.Id]" level="INFO" doc:name="Logger"/>
            <objectstore:store config-ref="ObjectStore__Connector" key="#[flowVars.varContact_id]" value-ref="#[payload.Id]" overwrite="true" doc:name="ObjectStore"/>
        </foreach>
    </flow>

在设置的有效负载下获取以下错误消息：

您为什么要设置有效负载是一种“创意”＆＃39;方式，没有必要，也没有用。

SalesForce连接器输出的类型为org.mule.streaming.ConsumerIterator，可以由For Each范围直接读取，因此这已经是一个集合。

删除Set Payload并查看是否有效，如果您调试，您应该看到行为，我刚刚对此进行了测试，这是有效的。

如何将salesforce select查询响应转换为mule中的可读格式？
