推荐答案

基于提供的信息，首先您将从远程服务器上获取文件，然后将其作为BLOB加载到数据库中.

Based on the info provided, first you will obtain the files from the remote server, then load them as a BLOB into a database.

有关典型的FTP流，请参见该图.第一个组件是与服务器的连接，该连接允许连接重用.第二个组件是可选的，它使您可以在操作之前获取文件计数(以后可以使用它来确保检索到所有文件).从技术上讲，第三个组件(tFTPGet)就是您所需要的.该组件实际上根据您设置的文件掩码获取文件.最后的组件tFTPDelete清理远程目录.

See the diagram for a typical FTP flow. The first component is a connection to the server which allows connection reuse. The second component is optional, it allows you to get a count of file prior to your operations (you can use it later to make sure you retrieved all the files). The third component (tFTPGet) is technically all you need. This component actually grabs the files based on the file mask you set. The final component tFTPDelete cleans up the remote directory.

在本地拥有文件后，请参见

Once you have the files locally see this help link for information on how to insert files as BLOBs into a database. You will have to tweak it for your SalesForce db.
