如何使用FTP连接器在Anypoint Studio中使用mule上传和下载文件？

Question

我尝试使用FTP连接器和FileZilla FTP服务器（xampp）。这是我的流程代码和输出。如果我正在使用SFTP，我将输出“连接被外部主机关闭”。

配置XML：

<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns:file="http://www.mulesoft.org/schema/mule/file" xmlns:sftp="http://www.mulesoft.org/schema/mule/sftp" xmlns:ftp="http://www.mulesoft.org/schema/mule/ee/ftp" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

    <ftp:connector name="FTP" pollingFrequency="1000" validateConnections="true" outputPattern="output.json" doc:name="FTP"/>
    <flow name="ftpFlow">
        <file:inbound-endpoint path="D:\Data\input" connector-ref="FileRead" pollingFrequency="100000" responseTimeout="10000" doc:name="File"/>
        <ftp:outbound-endpoint host="127.0.0.1" port="14147" passive="true" responseTimeout="10000" doc:name="FTP" connector-ref="FTP" outputPattern="output.json" password="kamal" path="/" user="kamal"/>
    </flow>
</mule>

控制台输出：

Answer 1

File Zilla的侦听端口是21.端口14147是管理端口。

Answer 2

使用那里提供的小小groovy脚本。这应该工作。我只是测试了这个并按预期工作。删除可以通过autoDelete属性或fileAge来完成。请告诉我这是否有帮助

<flow name="ftptestFlow">
    <ftp:inbound-endpoint host="hostname" port="port" path="path/filename" user="userid" password="password" responseTimeout="10000" doc:name="FTP"/>
    <set-variable variableName="fileName" value="fileName" doc:name="fileName"/>
    <scripting:component doc:name="getFile">
        <scripting:script engine="Groovy"><![CDATA[new File(flowVars.fileName).getText('UTF-8')]]></scripting:script>
    </scripting:component>
    <file:outbound-endpoint path="path" outputPattern="filename" responseTimeout="10000" doc:name="File"/>
</flow>
