http - Mule - HTTP Post - 超过超时

Question

这是我的基本骡子流程:

HTTP 监听器 > Logger > Http Request > Logger(结果消息)

<http:request-config name="HTTP_Request_Configuration" host="localhost" port="8080" doc:name="HTTP Request Configuration" usePersistentConnections="false"/>
<http:listener-config name="HTTP_Listener_Configuration" host="0.0.0.0" port="8081" doc:name="HTTP Listener Configuration"/>
<flow name="servoy-restFlow">
    <http:listener config-ref="HTTP_Listener_Configuration"
        path="/" doc:name="HTTP" />
    <logger message="#[message.payloadAs(java.lang.String)]" level="INFO"
        doc:name="Logger" />
    <http:request config-ref="HTTP_Request_Configuration"
        path="service/rest/request" method="POST"
        doc:name="HTTP" />
    <logger message="#[message.payloadAs(java.lang.String)]" level="INFO"
        doc:name="Logger" />
</flow>

但是它返回一个关于超时异常的错误:

我应该怎么做才能避免超时？

Answer 1

http outbound request 的默认超时是 30 秒，在 mule 中以 ms 指定。将 http-request 配置的超时时间增加到大于 30 秒，可以从 40 秒开始，看看你想要的数字是多少。

<http:request-config responseTimeout="40000" .../>
