SFTP客户端列表服务参数"ModificationTime“

Question

要求：-从5分钟前修改过的服务器中选择文件，然后移动到本地服务器。

我想了解Sterling B2B Integrator中的SFTP客户端列表服务，它有一个参数B2B，我想使用它来查找最后修改的文件，5分钟后，它才会被选择并传输到本地服务器。这个参数有帮助吗。

这就是我正在尝试的

    <operation name="SFTP Client LIST Service">
        <participant name="SFTPClientList"/>
        <output message="SFTPClientListServiceTypeInputMessage">
            <assign to="RemoteFileName" from="/ProcessData/Interface/REMOTEFILEPATTERN/text()"/>
            <assign to="ModificationTime">300</assign>
            <assign to="ResponseTimeout">120</assign>
            <assign to="WF_RUNTIME_OVERRIDE_PERSISTENCE_LEVEL">PERSISTENCE_FULL</assign>
            <assign to="." from="*"/>
        </output>
        <input message="inmsg">
            <assign to="." from="*"/>
        </input>
    </operation>

ModificationTime是一个输出参数，它是远程sftp命令的结果。

参见示例BP，它列出了TXT (*.txt)文件：

<process name = "Demo_BP_SFTP_List"> 
    
<sequence name="Demo_BP_SFTP_List">

    <!-- Begin Session -->
    <operation name="SFTP Client Begin Session Service">
      <participant name="SFTPClientBeginSession"/>
      <output message="SFTPClientBeginSessionServiceTypeInputMessage">
        <assign to="SFTPClientAdapter">SFTPClientAdapter</assign>
        <assign to="RemoteHost">127.0.0.1</assign>
        <assign to="RemotePort">22</assign>
        <assign to="RemoteUserId">Demo_Remote_SFTP</assign>
        <assign to="RemotePasswd">passw0rd</assign>
        <assign to="PreferredAuthenticationMethod">password</assign>
        <assign to="KnownHostKeyId">442297176384f4ba2node1</assign>
        <assign to="." from="*"></assign>
      </output>
      <input message="inmsg">
        <assign to="SFTPClientBeginSessionServiceResults" from="*"></assign>
      </input>
    </operation>

    <operation name="SFTP Client LIST Service">
        <participant name="SFTPClientList"/>
        <output message="SFTPClientListServiceTypeInputMessage">
            <assign to="RemoteFileName">*.txt</assign>
            <assign to="SessionToken" from="SFTPClientBeginSessionServiceResults/SessionToken/text()"></assign>
            <assign to="." from="*"/>
        </output>
        <input message="inmsg">
            <assign to="SFTPClientLISTServiceResults" from="*"></assign>
        </input>
    </operation>
                      
    <operation name="SFTP Client End Session Service">
        <participant name="SFTPClientEndSession"/>
        <output message="SFTPClientEndSessionServiceTypeInputMessage">
            <assign to="SessionToken" from="SFTPClientBeginSessionServiceResults/SessionToken/text()"></assign>
            <assign to="." from="*"></assign>
        </output>
        <input message="inmsg">
            <assign to="SFTPClientEndSessionServiceResults" from="*"></assign>
        </input>
    </operation>

</sequence>
</process>

产出如下：

</ProcessData>
....
  </SFTPClientLISTServiceResults>
....
    <Files>
      <File>
        <Name>testdata01.txt</Name>
        <Size>11</Size>
        <Type>Regular</Type>
        <Permissions>-rw-rw-r--</Permissions>
        <ModificationTime>1611017370</ModificationTime>
        <Owner>Demo_Remote_SFTP</Owner>
        <Group>Demo_Remote_SFTP</Group>
      </File>
      <File>
        <Name>testdata02.txt</Name>
        <Size>11</Size>
        <Type>Regular</Type>
        <Permissions>-rw-rw-r--</Permissions>
        <ModificationTime>1611017385</ModificationTime>
        <Owner>Demo_Remote_SFTP</Owner>
        <Group>Demo_Remote_SFTP</Group>
      </File>
      <File>
        <Name>testdata03.txt</Name>
        <Size>12</Size>
        <Type>Regular</Type>
        <Permissions>-rw-rw-r--</Permissions>
        <ModificationTime>1611017399</ModificationTime>
        <Owner>Demo_Remote_SFTP</Owner>
        <Group>Demo_Remote_SFTP</Group>
      </File>
    </Files>
  </SFTPClientLISTServiceResults>
</ProcessData>

您需要创建一个循环，并检查ModificationTime是否减少了当前时间-5分钟，并执行SFTP客户端获取服务。
