你可以在mulesoft上获得每个语句的附件文件名吗？

Question

我有一个电子邮件文件场景。该电子邮件包含多个附件，我需要逐一处理它们以传递给另一个流程，并且我需要原始文件名。我可以在每个作用域之前获取附件名称，但我无法将其作为目标文件的文件名。任何帮助或建议将真正赞赏。

好，

不知道这是否会成为，但我已经实现了下面的代码为IMAP帐户：

<choice doc:name="Choice between mail with and without attachments"> 
     <when expression="#[message.dataType.mimeType == &quot;multipart/alternative&quot;]"> 
      <set-variable variableName="hasAttachment" value="false" doc:name="Set hasAttachment"/> 
      <set-payload value="#[message.inboundAttachments['0'].getContent()]" doc:name="Set Payload from Body"></set-payload> 
      <set-variable variableName="fileName" value="" doc:name="Set fileName"/> 
     </when> 
     <when expression="#[message.dataType.mimeType == &quot;multipart/mixed&quot;]"> 
      <set-variable variableName="hasAttachment" value="true" doc:name="Set hasAttachment"/> 
      <expression-transformer doc:name="Set Payload from Attachments"> 
       <return-argument evaluator="attachments" expression="*.*"/> 
      </expression-transformer> 
      <set-variable variableName="fileName" value="#[payload.keySet().iterator().next()]" doc:name="Set fileName"/> 
      <set-payload value="#[payload[flowVars.fileName].getContent()]" doc:name="Set Payload from firts Attachment content"></set-payload> 
      <object-to-byte-array-transformer doc:name="Object to Byte Array"></object-to-byte-array-transformer> 
     </when> 
     <when expression="#[message.dataType.mimeType == &quot;text/plain&quot;]"> 
      <set-variable variableName="hasAttachment" value="false" doc:name="Set hasAttachment"/> 
      <set-payload value="#[payload.getContent()]" doc:name="Set Payload from Text"/> 
      <set-variable variableName="fileName" value="" doc:name="Set fileName"/> 
     </when> 
     <otherwise> 
      <logger message="La informaci&#243;n del EMail no es v&#225;lida" level="INFO" doc:name="Logger"/> 
     </otherwise> 
    </choice> 

正如你可以在在“＃[见message.dataType.mimeType == " multipart/mixed "]“，检索所有附件，在我的情况下，其中第一个附件的迭代器的第一个值为：

#[payload.keySet().iterator().next()] 

使用此名称，您可以直接访问此附件的内容，或者您​​可以使用相应的密钥访问它们。

问候。

使用＃[键]，这会给foreach语句中的文件名。 我正在使用3.8版本
