Question

使用WSO2 ESB

我需要调用rest服务并迭代其响应以查找嵌套值。通过第一次呼叫的响应，我想呼叫第二个服务并提供从第一个服务收到的数据。

给出下面的配置示例;

对第一个服务的调用成功，返回一个或多个目标值
当迭代第一个调用的响应时，我可以通过Log Mediator看到目标数据
对第二个呼叫中介的呼叫不会将我在第二个端点的日志中介中看到的数据{uri.var.destination}

似乎我错过了如何从第一次调用中获取数据并将其放置在第二个http端点的后续调用中，如我的第二个Call Mediator发送以下i_param2 = {uri.var.destination}所证明的那样我预期它是i_param2 = 41st＆amp;橡木

非常感谢任何建议和观点。

以下是我的API的一小部分，对不起如此冗长，但我想展示服务链，以防它是我的配置导致问题：

    <?xml version="1.0" encoding="UTF-8"?>
<api context="/updatebusdisplay" name="UpdateBusDisplay" xmlns="http://ws.apache.org/ns/synapse">
  <resource methods="GET" protocol="http" url-mapping="/foo">
    <inSequence>
      <call>
        <endpoint>
          <http method="get" trace="disable" uri-template="http://api.translink.ca/rttiapi/v1/stops/50641/estimates?apikey=REMOVED&amp;count=1&amp;timeframe=1440"/>
        </endpoint>
      </call>
      <iterate expression="//Destination" id="it1" preservePayload="true">
        <target>
          <sequence>
            <property description="" expression="//Destination/text()"
              name="uri.var.destination" scope="default" type="STRING"/>
            <log description="" level="full">
              <property expression="get-property('uri.var.destination')" name="property_name"/>
            </log>
            <call>
              <endpoint>
                <http method="get" trace="disable" uri-template="http://jupiter.signage.me/WebService/sendCommand.ashx?i_userpass=REMOVED&amp;i_stationId=41&amp;i_command=event&amp;i_param1=nameone&amp;i_param2={uri.var.destination}"/>
              </endpoint>
            </call>
            <log level="full"/>
          </sequence>
        </target>
      </iterate>
    </inSequence>

使用wirelog复制控制台，显示每次通话中的值以及第一次通话时的响应，我已删除大部分日志以保持较小（呃）：

Answer 1

由@JavaMasterRSA确认（非常感谢），问题与我的包含无效字符的数据有关。

以下内容有用URI- template encoding in WSO2 ESB for reserved characters

使用REST我无法遍历一个呼叫的响应数据并在第二个呼叫中介
