骡子文件传输以从 Windows SMB 共享读取文件

Question

我正在尝试将文件写入Windows SMB共享。Mule File Transport 文档说我应该能够访问 Windows 位置，如下所示：file:////192.168.0.1/temp/

这是我的骡子流：我想知道是否有解决方案。谢谢！

<file:outbound-endpoint   responseTimeout="10000" doc:name="File" address="file:////<IPAddress>/ShareName/" outputPattern="hello.xml"/>

我收到以下错误：

当 Mule 在 Windows 操作系统上执行时，使用文件传输访问 UNC 路径时有效。

由于您似乎在Unix机器中，因此您必须使用CIFS/SMB协议。有一个社区支持的模块称为mule-transport-cifs，可以帮助您解决这个问题。

将此模块添加到您的项目后，您应该能够通过将文件出站追逐到类似这样的东西来使用它。

<smb:outbound-endpoint host="<IPAddress>" user="username" password="secret" path="/ShareName" outputPattern="hello.xml"/>
