Webmethods - Retrieve PDF file from SFTP and encode

Question

I am new to webmethods and need some guidance. I am tasked to read the PDF document from SFTP server and base64 encode it. I have managed to GET the file from SFTP location and now struggling to encode it. Below is the code snippet to read the file:

INVOKE pub.client.sftp:login
INVOKE pub.client.sftp:cd
INVOKE pub.client.sftp:ls
INVOKE pub.client.sftp:get
MAP

I later modified the code to include base64 encoding, no output is produced. Code is shown below:

INVOKE pub.client.sftp:login
INVOKE pub.client.sftp:cd
INVOKE pub.client.sftp:ls
INVOKE pub.client.sftp:get
INVOKE pub.string:base64Encode
MAP

when i debug the code, it executes SFTP GET and stops. No information about encoding.

Please guide me to achieve this requirement. Thank you for your help in advance.

Answer 1

The pub.string:base64Encode expect a byte[] Input, you can try to convert the stream to byte[] with pub.io:streamToBytes

Answer 2

Try something like this, after sftp:get, invoke the pub.io:streamToBytes and then invoke pub.string:base64Encode

Don't forget to map field in pipeline.
