如何使用请求路径在 Mule ESB 中进行路由

Question

您好，我正在尝试在流程中添加路由器，以便我可以重新使用我的代码并避免重复。

我通常为每个请求路径做一个流程，例如：

HTTP 侦听器 = localhost:8080/mule1 HTTP 侦听器 = localhost:8080/mule2

我想知道是否可以使用请求路径通过 Router/Choice 连接器进行路由。我无法这样做，因为它告诉我只有 /

的侦听器

这是我的代码：

<flow name="Tickets">
        <http:listener config-ref="HTTP_Listener_Configuration" path="/" doc:name="HTTP"/>
        <logger message="#[message.inboundProperties.'http.listener.path']" level="INFO" doc:name="Logger"/>
        <choice doc:name="Choice">
            <when expression="#[message.inboundProperties.'http.request.path' == &quot;/getTicketByTicketCode&quot;]">
                <set-payload value="#[message.inboundProperties.'http.query.params'.ticketcode]" doc:name="Set Payload"/>
                <scripting:component doc:name="Groovy">
                    <scripting:script engine="Groovy"><![CDATA[def writer = new StringWriter() 
def xml = new groovy.xml.MarkupBuilder(writer)
xml.mkp.xmlDeclaration(version: "1.0", encoding: "UTF-8")
xml.GetTicketByCode(xmlns: 'http://tempuri.org/') { 
  code(payload)
} 
result = writer.toString() ]]></scripting:script>
                </scripting:component>
                <ws:consumer config-ref="Web_Service_Consumer" operation="GetTicketByCode" doc:name="Web Service Consumer"/>
            </when>
            <when expression="#[message.inboundProperties.'http.request.path' == &quot;/validateTickets&quot;]">
                <scripting:component doc:name="Groovy">
                    <scripting:script engine="Groovy"><![CDATA[]]></scripting:script>
                </scripting:component>
                <ws:consumer config-ref="Web_Service_Consumer" operation="ValidateTicket" doc:name="Web Service Consumer"/>
            </when>
        </choice>
        <mulexml:xslt-transformer xsl-file="removeattributes.xsl" maxIdleTransformers="2" maxActiveTransformers="5" doc:name="XSLT"/>
        <json:xml-to-json-transformer doc:name="XML to JSON"/>
    </flow>

有没有办法让它工作？或者是唯一的方法是添加另一个 queryParam 就像路径一样。谢谢

您可以使用以下 path="/*"，我已将您的流程修改如下：-

<flow name="Tickets">
        <http:listener config-ref="HTTP_Listener_Configuration" path="/*" doc:name="HTTP"/>
        <logger message="#[message.inboundProperties.'http.listener.path']" level="INFO" doc:name="Logger"/>
        <choice doc:name="Choice">
            <when expression="#[message.inboundProperties.'http.request.path'.contains('/getTicketByTicketCode')]">
                 <logger message="getTicketByTicketCode flow" level="INFO" doc:name="Logger"/>
                 <set-payload value="#[message.inboundProperties.'http.query.params'.ticketcode]" doc:name="Set Payload"/>
                <scripting:component doc:name="Groovy">
                    <scripting:script engine="Groovy"><![CDATA[def writer = new StringWriter() 
def xml = new groovy.xml.MarkupBuilder(writer)
xml.mkp.xmlDeclaration(version: "1.0", encoding: "UTF-8")
xml.GetTicketByCode(xmlns: 'http://tempuri.org/') { 
  code(payload)
} 
result = writer.toString() ]]></scripting:script>
                </scripting:component>
                <ws:consumer config-ref="Web_Service_Consumer" operation="GetTicketByCode" doc:name="Web Service Consumer"/>

            </when>
            <when expression="#[message.inboundProperties.'http.request.path'.contains('/validateTickets')]">
                 <logger message="validateTickets flow" level="INFO" doc:name="Logger"/> 
                  <scripting:component doc:name="Groovy">
                    <scripting:script engine="Groovy"><![CDATA[]]></scripting:script>
                </scripting:component>
                <ws:consumer config-ref="Web_Service_Consumer" operation="ValidateTicket" doc:name="Web Service Consumer"/>
            </when>
            <otherwise>
               <logger message="Other than this url " level="INFO" doc:name="Logger"/> 

            </otherwise>

           <mulexml:xslt-transformer xsl-file="removeattributes.xsl" maxIdleTransformers="2" maxActiveTransformers="5" doc:name="XSLT"/>
        <json:xml-to-json-transformer doc:name="XML to JSON"/> 
        </choice>

    </flow>

现在如果你的 url 包含 getTicketByTicketCode 那么它将转到第一个流程，如果它包含 validateTickets 它将进入第二个流程....

否则，如果它没有这 2 个中的任何一个，它将在 otherwise 条件

中打印记录器
