Question

我正在尝试使用WSO2 ESB进行基于FTP的集成。我可以使用VFS传输将文件从一个FTP位置传输到另一个FTP位置。但WSO2 ESB预计文件中的肥皂信封正在转移。

如果Am传输图像，此逻辑将不适合。

如何使用VFS传输传输带有非肥皂信封的图像/文件？

如果我转移任何没有肥皂信封的文件，则会出现以下错误：

这很可能是因为未使用VFS传输的右ContentType。

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上尝试了它，并且它对于png文件工作正常，而使用text/plain作为transport.vfs.ContentType参数的值则抛出了与您描述的相同的异常。 / p>

查看Synapse VFS服务参数here。
