passing javascript object from one channel to other channel in mirth

Question

In Channel A i am getting XML as input.Incoming XML mentioned below:

 <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<bookstore>
<books>
<book>
<title>SpringInAction</title>
<NoOfCopies>10</NoOfCopies>
</book>
<book>
<title>HibernateInAction</title>
<NoOfCopies>8</NoOfCopies>
</book>
<book>
<title>JSFInAction</title>
<NoOfCopies>5</NoOfCopies>
</book>
<book>
<title>StrutsInAction</title>
<NoOfCopies>9</NoOfCopies>
</book>
<book>
<title>JSPInAction</title>
<NoOfCopies>4</NoOfCopies>
</book>
</books>
</bookstore>

I am parsing this XML in Edit Transformer of the Source and making JavaScript object and putting this JavaScript object into a channel Map like this:

var book=new Object();
book.title = msg['books']['book'][0]['title'].toString();
book.copies = msg['books']['book'][0]['NoOfCopies'].toString();
logger.info("book "+book);
channelMap.put("book",book);

Now i want to pass this JavaScript object to other Channel B from destination of Channel A and Channel B receives this JavaScript object as input and does the rest of the processing .Is it possible in Mirth?

I am using Mirth Version 2.2.1.5861.

Answer 1

Before saving the channel variable, serialize it (json object).

In your channel destination, write out the "book" variable.

So something like this:

In Transformer

var book=new Object();
book.title = msg['books']['book'][0]['title'].toString();
book.copies = msg['books']['book'][0]['NoOfCopies'].toString();
logger.info("book "+book);

var Jbook = JSON.stringify(book);
channelMap.put("Jbook",Jbook );

In Destination Template

${jbook}

Then on the receiving channel

var book = JSON.parse(msg.toString());

I have not verified this code, but it should give you a coding strategy.

See Mirth Discussion about JSON
