Mirth Connect：处理附件

Question

Mirth Connect Server 3.5.1, Java version: 1.8.0_171

I've successfully sent form-data from POSTMAN (see postman.xml) to MIRTH (see below JavaScript Writer). My JavaScript Writer can grab all info except I got stuck on what to do with the base64 file content.

This code run without error but the email I received got no attachment. Everything else is good.

postman.xml:

Answer 1

Your problem is, that you are using addAttachment method. If you just call this method like you do, then it has nothing to do with the email object that you are putting together, but it instead adds an attachment to the Mirth message. You should see an attachments tab with your attachments in the channel for the messages you have processed.

Read the documentation how to add attachments in the email library you are using, and act accordingly. Maybe it is as simple as calling email.addAttachment() , but I don't know.

PS. Instead of splitting the XML string by hand, why not use Mirth's XML handling capabilities to access the different parts of XML?

PPS. Why not use Mirth's SMTP sender instead of doing it all by hand?
