Question

我在代理服务中使用WSO2 ESB Twitter连接器操作。代理配置如下所示

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="twitter_test_proxy" transports="http https" startOnLoad="true" trace="disable">
    <target>
        <inSequence>
            <twitter.init configKey="twitter_init"/>
            <twitter.getTopTrendPlaces configKey="twitter_init">
                <id>23424975</id>
            </twitter.getTopTrendPlaces>
        </inSequence>
        <outSequence/>
        <faultSequence/>
    </target>
</proxy>

我将twitter连接器导入esb并启用它。然后，所有工件（代理服务和twitter_init本地条目）都部署在ESB中。一旦我调用代理服务，就注意到twitter连接器没有调用预期的后端twitter API。我已启用了线程调试和调试日志，如下所示。这是什么原因？我正在使用WSO2 ESB 4.8.1。我按照here给出的说明创建了配置

我可以通过稍微修改代理来解决上述问题。我添加了响应中介并得到了预期的结果。工作代理如下所示。

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse" name="twitter-connector-proxy" transports="http https" startOnLoad="true" trace="disable">
    <target>
        <inSequence>
            <log level="full">
                <property name="INIT" value="##### Call to the Proxy #####"/>
            </log>
            <twitter.init/>
            <twitter.search configKey="twitter_init">
                <search>cricket</search>
            </twitter.search>
            <log level="full">
                <property name="RESULT" value="#### Twitter Search Result ####"/>
            </log>
            <respond/>
        </inSequence>
        <outSequence/>
        <faultSequence/>
    </target>
</proxy>

wso2 esb twitter连接器没有调用twitter api
