Question

我正在尝试在mule中使用facebook连接器，我有2个流程，一个用于授权，另一个用于在facebook中发布简单文本。问题是在授权我的程序后，我丢失了accessTokenID，并且无法保存。

        <json:object-to-json-transformer doc:name="Object to JSON"/>
    </flow>
</mule>

这是我在cloudhub中遇到的错误：

任何人都可以帮助我吗？我认为会话变量不会被保存，但我无法证明它。提前致谢

Answer 1

这里有一个主要的斜杠：＃[flowVars [＆＃39; OAuthAccessTokenId＆＃39;]]和这里：＃[sessionVars [＆＃39; accessTokenId＆＃39;]]。尝试删除它们，也尝试记录该值

Answer 2

供将来参考，截至目前： https://github.com/mulesoft/facebook-connector/blob/master/doc/sample.md上的代码是错误的，在流程中它使用了与我的代码相同的'\'：

<flow name="Authorize" doc:name="Authorize">
    <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" doc:name="HTTP"/>
    <facebook:authorize config-ref="Facebook-config" doc:name="Authorize"/>
    <set-session-variable doc:name="Save Access Token" value="\#[flowVars['OAuthAccessTokenId']]" variableName="accessTokenId"/>
    <flow-ref name="PhotoDownload" doc:name="Call Photo Download"/>
</flow>

希望将来能够纠正它
