我正在尝试使用 WSO2 ESB 进行基于 FTP 的集成。我能够使用 VFS 传输将文件从一个 FTP 位置传输到另一个位置。但是 WSO2 ESB 期望文件中的肥皂信封正在传输。

如果我正在传输图像，则此逻辑将不适合。

如何使用 VFS 传输传输具有非肥皂信封的图像/文件？

如果我在没有肥皂信封的情况下传输任何文件，则会发生以下错误：

这很可能是因为ContentType没有使用 VFS 传输的权限。

传输二进制数据时，请使用：

<parameter name="transport.vfs.ContentType">application/octet-stream</parameter>

我刚刚在 WSO2 ESB 4.0.3 上尝试过它，它适用于 png 文件，而使用参数text/plain的值会transport.vfs.ContentType引发与您描述的相同的异常。

在此处查看 Synapse VFS 服务参数。
