使用 Mule 更改 url 属性值

Question

我正在尝试构建一个根据 URL 值更改 URL 的应用程序。 我到目前为止的代码是：

<flow name="CalculadoraHttpsSoap12Endpoint" doc:name="CalculadoraHttpsSoap12Endpoint">
    <http:inbound-endpoint exchange-pattern="request-response" address="${serverName}/Calculadora/services/Calculadora.CalculadoraHttpsSoap12Endpoint/" connector-ref="" doc:name="HTTP"/>
    <http:outbound-endpoint address="${targetServer4}/Calculadora/services/Calculadora.CalculadoraHttpsSoap12Endpoint/" exchange-pattern="request-response"/>
</flow>

此代码仅从 ${serverName}/Calculadora/services/Calculadora.CalculadoraHttpsSoap12Endpoint 获取消息并将其发送到 ${targetServer4}/Calculadora/services/Calculadora.CalculadoraHttpsSoap12Endpoint/ 但我想要做的是如果某些消息是${serverName}/Calculadora/services/Calculadora.CalculadoraHttpsSoap12Endpoint?att=1234 将其更改为 ${serverName}/Calculadora/services/Calculadora.CalculadoraHttpsSoap12Endpoint?att1=4567 并将其发送到出站位置，任何有关如何操作的线索或文章做吗？

骡子版本 3.4.0

Answer 1

可以获取查询字符串并定义变量：

<set-variable variableName="myAtt" value="#[message.inboundProperties['http.query.string'] == 'att=1234' ? '?att1=4567' : '']"/>
<set-variable variableName="myUrl" value="#[message.inboundProperties['http.query.string'] == 'att=1234' ? 'localhost' : '${targetServer4}']" />

<http:outbound-endpoint address="http://#[myUrl]/somepath/#[myAtt]" exchange-pattern="request-response"/>
