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 中发布一个简单的文本。问题是授权我的程序后，我丢失了accessTokenID，并且无法保存。

    </flow>
</mule>

这是我在 cloudhub 中遇到的错误：

    + 3 more (set debug level logging or '-Dmule.verbose.exceptions=true' for everything)

任何人都可以帮助我吗？我认为会话变量不会被保存，但我无法证明这一点。提前致谢

这里有一个前导斜杠：#[flowVars['OAuthAccessTokenId']] 和这里：#[sessionVars['accessTokenId']]。尝试删除那些，也尝试记录值

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相同的“\”我的代码：

<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>

希望他们将来会纠正它
