Layer7 API Management

Hi All,

We are trying to make a multipart message from scratch - with a binary attachment (e.g. a zip or pdf file). 

Is there any way to create such a message? When we try to use the set context Variable assertion and add the attachment as text, it's not a binary file anymore. Base 64 is not an option.

Perhaps there is a tactical assertion - create a multipart message, or something like that?

Thanks,

Jan Jaap

Hi Jan,

There is a tactical assertion for creating a MIME message. You will need to create a support ticket requesting access to the tactical assertion.

Hi Barry,

Thanks for your help. Do you happen to know if this works for a binary multipart too?

Will open a case an request to check.

Thanks,

Jan Jaap

Jan,

The Tactical assertion you want to request is AssembleMimeMessage 

Support will need you exact gateway version from the rpm -qa | grep ssg.

There is no specific reference to binary in the user documentation of the tactical assertion.

But you can specify the content header type and at first glance I dont see a reason why it couldnt include binary files, but I havent specifically tested it.

Thanks.

Hi Charles, 

Thanks for your reply, I have opened a case and requested the assertion. Creating a multipart message with set context var doesn't work since the gateway tries to interpred the binary string which fails - creating a corrupted file. I fear that the tatical assertion also only works for string values (or base 64 encoded attachments) but will try it to be sure.

Thanks.

Please let us know if the assertion did what you are looking to do. If not please log a idea on our community for this use case.

Sincerely,

Stephen Hughes
