Question

我有这个mule流，它在其中轮询源文件夹以读取我作为附件添加并通过REST调用发送的文本文件，我尝试在不同流程中读取的相同附件但是入站附件即将到来如果为null，请查看代码并帮助我。

<flow name="createAttachment" doc:description="Reading file and sending as attachment.">
    <file:inbound-endpoint path="src/test/resources/in/attachment/" responseTimeout="10000" doc:name="File"/>
    <file:file-to-byte-array-transformer doc:name="File to Byte Array"/>
 <!--    <set-attachment attachmentName="#[originalFilename]" value="#[payload]" contentType="multipart/form-data" doc:name="Attachment"/>  -->
  <set-attachment attachmentName="#[originalFilename]" value="#[payload]" contentType="multipart/form-data" doc:name="Attachment" />
    <http:request config-ref="HTTP_Request_Configuration" path="attachment/excel"  method="POST" doc:name="HTTP"/>
</flow>


<flow name="readAttachment">
 <http:listener config-ref="HTTP_Listener_Configuration" path="attachment/excel" allowedMethods="POST" parseRequest="false" />
    <set-payload value="#[message.inboundAttachments['myattachment.txt']]" doc:name="Retrieve Attachments"/> 
      <set-payload value="#[payload.getInputStream() ]" doc:name="Get Inputstream from Payload"/>
        <file:outbound-endpoint path="src/test/resources/out/attachment" responseTimeout="10000" doc:name="File" outputPattern="#[server.dateTime.toString()].pdf"/>

</flow>

Answer 1

我使用了以下内容：

<flow name="readAttachment">
    <http:listener config-ref="HTTP_Listener_Configuration"
        path="/" allowedMethods="POST" parseRequest="false" doc:name="HTTP" />
    <byte-array-to-string-transformer doc:name="Byte Array to String"/>
    <logger message="#[payload]" level="INFO" doc:name="Logger" /><file:outbound-endpoint path="src/test/resources" connector-ref="File" responseTimeout="10000" doc:name="File"/>

</flow>

当收到附件时，它会被自动解析为有效负载，因此只是将字节数组转换为字符串。

我希望这会有所帮助
