Wso2 ESB twitter连接器不工作

Question

我已经通过参考文档创建了wso2 twitter连接器的示例项目。 Twitter Connector Documentation

代理配置如下

<?xml version="1.0" encoding="UTF-8"?> 
<proxy xmlns="http://ws.apache.org/ns/synapse" 
     name="twitter-connector-proxy" 
     transports="https,http" 
     statistics="enable" 
     trace="enable" 
     startOnLoad="true"> 
    <target> 
     <inSequence> 
     <log level="custom"> 
      <property name="INIT" value="************ init proxy *************"/> 
     </log> 
     <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> 
    <description/> 
</proxy> 

而本地条目如下

<twitter.init xmlns="http://ws.apache.org/ns/synapse"> 
     <consumerKey>***</consumerKey> 
     <consumerSecret>***</consumerSecret> 
     <accessToken>***</accessToken> 
     <accessTokenSecret>****</accessTokenSecret> 
</twitter.init> 

我还进口了Twitter的证书ESB客户端密钥库。当我测试代理时，我收到以下错误日志。

请使用此代理尝试。

<?xml version="1.0" encoding="UTF-8"?> 
<proxy xmlns="http://ws.apache.org/ns/synapse" 
     name="twitter_search" 
     transports="https,http" 
     statistics="disable" 
     trace="disable" 
     startOnLoad="true"> 
    <target> 
     <inSequence onError="faultHandlerSeq"> 
     <property name="consumerKey" expression="json-eval($.consumerKey)"/> 
     <property name="consumerSecret" expression="json-eval($.consumerSecret)"/> 
     <property name="accessToken" expression="json-eval($.accessToken)"/> 
     <property name="accessTokenSecret" expression="json-eval($.accessTokenSecret)"/> 
     <twitter.init> 
      <consumerKey>{$ctx:consumerKey}</consumerKey> 
      <consumerSecret>{$ctx:consumerSecret}</consumerSecret> 
      <accessToken>{$ctx:accessToken}</accessToken> 
      <accessTokenSecret>{$ctx:accessTokenSecret}</accessTokenSecret> 
     </twitter.init> 
     <twitter.search> 
      <search>Cricket</search> 
     </twitter.search> 
     <respond/> 
     </inSequence> 
     <outSequence> 
     <send/> 
     </outSequence> 
    </target> 
    <description/> 
</proxy> 

并发送请求正文如下：

{ 
    "consumerKey":"xxxx", 
    "consumerSecret":"xxxx", 
    "accessToken":"xxxx", 
    "accessTokenSecret":"xxxx" 
}
