Question

让我先说一下：我不是开发人员。我目前正在使用Mulesoft集成多个系统（最初由外包开发人员开发的应用程序）。该应用程序的一部分是合并可能在系统中通用的记录。为此，我使用记录名称和地理编码作为关联地址。直到过去一周这个工作正常。现在，当应用程序的这部分运行时，我收到错误。来自失败的特定调用的调试日志是：

问题似乎与地理编码API本身无关，因为我可以手动调用相同的地址而不会出现任何问题。连接受到限制，因此我们不应该遇到每秒请求的任何限制。这是管理API调用的应用程序中的一段代码：

<flow name="rpm-geocode-lookup" processingStrategy="synchronous">
    <set-payload value="#[payload.addressLine1],#[payload.city],#[payload.state]" doc:name="Set Location"/>
    <ee:cache cachingStrategy-ref="GeocoderCachingStrategy" doc:name="Geocoder Cache">
        <json:object-to-json-transformer doc:name="Object to JSON"/>
        <logger level="DEBUG" category="com.tbosa.esb.rpm" message="Making call to Geocoder for #[payload]" doc:name="Not Cached"/>
        <http:request config-ref="GeocoderRequest" path="/geocode/json" method="GET" doc:name="Geocoder Request">
            <http:request-builder>
                <http:query-param paramName="key" value="${geocoder.key}"/>
                <http:query-param paramName="address" value="#[payload]"/>
            </http:request-builder>
        </http:request>
        <json:json-to-object-transformer returnClass="java.util.Map" doc:name="JSON to Object"/>
        <choice doc:name="Choice">
            <when expression="#[payload.status == 'OK' || payload.results.size() &gt; 0]">
                <set-payload value="#[new java.lang.String(payload.results[0].geometry.location.lat) + payload.results[0].geometry.location.lng]" doc:name="Latitude+Longitude"/>
            </when>
            <otherwise>
                <logger message="Geocoder did not return any results. Result: #[payload]" level="WARN" category="com.tbosa.esb.rpm" doc:name="Logger"/>
                <set-payload value="''" doc:name="Blank Value"/>
            </otherwise>
        </choice>
        <expression-component doc:name="Expression">Thread.sleep(${geocoder.throttle.delay});</expression-component>
    </ee:cache>
    <exception-strategy ref="EmailExceptionStrategy" doc:name="Exceptions"/>        
</flow>

申请没有变更。我们已经成功运行了9个月，所以我不确定问题出在哪里。我老老实实地倾向于与Mulesoft的问题，但他们试图告诉我这是API的一个问题。想法？

Answer 1

500错误表示在处理请求期间Google端发生了错误。您是否在短暂延迟后重试了请求？

尝试确定哪个Google IP地址会影响您的应用。您可以在执行应用程序的计算机上使用traceroute maps.googleapis.com和ping maps.googleapis.com。

如果500错误仍然存在，我建议在公共问题跟踪器中提交一个问题，其中包含traceroute和ping的结果，示例问题的示例HTTP请求，公共IP地址和项目编号。

希望它有所帮助！
