Question

我有一个JSON响应，我想迭代并捕获事件的值数字，经度，纬度作为一个组，并将其发送到SMS消息服务。我试过了不同的方法，但我无法达到这些要素。我试过调试并使用
没有任何运气的不同表达。建议表示赞赏。

[
  {
    "type": " --T::00"
  },
  {
    "address": "2720 E Madison St",
    "longitude": "-122.296667",
    "latitude": "47.623153",
   "incident_number": "F110104004",
    "type": "Medic Response",
    "report_location": {
    "needs_recoding": false,
    "longitude": "-122.296667",
    "latitude": "47.623153"
   }
  },
 {
    "address": "2260 1st Av S",
    "longitude": "-122.334199",
    "latitude": "47.583347",
    "incident_number": "F110103709",
    "type": "Aid Response",
    "report_location": {
    "needs_recoding": false,
    "longitude": "-122.334199",
    "latitude": "47.583347"
  }
},
{
   "address": "1930 Boren Av",
   "longitude": "-122.333103",
   "latitude": "47.617173",
   "incident_number": "F110103707",
   "type": "Aid Response",
   "report_location": {
    "needs_recoding": false,
    "longitude": "-122.333103",
    "latitude": "47.617173"
 }
]

这是配置文件。

<flow name="seattleemergencyFlow1" doc:name="seattleemergencyFlow1">
    <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8900" path="get-emergency" doc:name="HTTP"/>
    <http:outbound-endpoint exchange-pattern="request-response" host="data.seattle.gov" port="80" path="resource/kzjm-xkqj.json?" method="GET" contentType="application/json" doc:name="HTTP"/>
    <json:json-to-object-transformer doc:name="JSON to Object" returnClass="java.util.List"/>
</flow>

Answer 1

使用List<Object>将json转换为json:json-to-object-transformer之后。您应该能够使用Mule的任何集合功能，例如foreach范围/路由器，然后使用MEL表达式来访问特定字段：

<foreach>
        <logger level="ERROR" message="#[payload.address]" />
</foreach>

Answer 2

您还可以使用

将json转换为xml数据

<json:json-to-xml-transformer doc:name="json-to-xml"/>

变换器并在for-each范围内提供xpath表达式，如下所示

<foreach collection="#[xpath('---')]" batchSize="--" doc:name="for-each-account-batch">

迭代Mulesoft中的JSON列表
