在我的代理服务器中,我拨打了一个远程休息服务,该服务通过以下消息回复我:

我需要从此消息中过滤一些数据并构建具有以下结构的自定义消息:
<clinicalManifestation>
<nonNeurological>
$1
</nonNeurological>
</clinicalManifestation>
哪里1美元,也许使用有效载荷工厂?应填充一些从前一个响应消息中提取的叶子,例如:
<clinicalManifestation>
<nonNeurological>
<growthWeight>Poor weight gain </growthWeight>
<growthOther>Failure to thrive </growthOther>
<headAndNeckEyes>Convergent squint</headAndNeckEyes>
<headAndNeckMouth>Trismus </headAndNeckMouth>
<respiratory>Apnea</respiratory>
<respiratoryLarynx>Laryngeal spasms</respiratoryLarynx>

我是否要在arqs声明中使用特定的xpath表达式使用有效负载工厂(什么表达式?)。或者我应该使用另一个调解员?哪一个?你能给我一个例子吗?
答案 0 :(得分:0)
您需要将它们指定为参数。让我从原始documentation中提取代码作为示例。这里的表达式表示xpath表达式。
<payloadFactory>
<format>
<m:checkpriceresponse xmlns:m="http://services.samples/xsd">
<m:code>$1</m:code>
<m:price>$2</m:price>
</m:checkpriceresponse>
</format>
<args>
<arg expression="//m0:symbol" xmlns:m0="http://services.samples/xsd">
<arg expression="//m0:last" xmlns:m0="http://services.samples/xsd">
</arg></arg></args>
</payloadFactory>

首先,在你的outSequence中(在得到回复之后)你需要从该响应中提取xml标签/字段,并将它们存储在属性中,以便我们以后可以使用它们......
例如(使用xpath):
<property name="growthWeight" expression="//omin/entryList/entry/clinincalSynopsis/growthWeight/text()" scope="default" type="STRING" />
<property name="growthOth" expression="//omin/entryList/entry/clinincalSynopsis/growthOther/text()" scope="default" type="STRING" />
等等,如果该xpath不起作用,请参阅(参见http://www.w3schools.com/xpath/xpath_syntax.asp)
您可以将这些属性打印到日志中,以查看它们是否设置正确:
<log level="custom">
<property xmlns:ns="http://org.apache.synapse/xsd" name="Extracted: Growth weight= " expression="$ctx:growthWeight"/>
<property xmlns:ns="http://org.apache.synapse/xsd" name="Extracted: Growth other= " expression="$ctx:growthOth"/>
</log>
然后在您的有效负载工厂中,您可以将这些属性设置为对客户端的最终响应的参数:
<payloadFactory media-type="xml">
<format>
<clinicalManifestation>
<nonNeurological>
<growthWeight>$1</growthWeight>
<growthOther>$2</growthOther>
:
:
:
</nonNeurological>
</clinicalManifestation>
</format>
<args>
<arg evaluator="xml" expression="$ctx:growthWeight" />
<arg evaluator="xml" expression="$ctx:growthOth" />
:
:
:
</args>
</payloadFactory>

我以更有效的方式处理了xml ...介体为我提供了更大的灵活性。
