Dynamically add nodes in JSON message

[Nicolas.Afonso]

Hi folks

 

Here is my use-case : my JSON message coming from backend contains some business deals. Each one can be expressed in its own currency.

So depending on localization of consumer, I have to add a node below each offer currency indicating its exchange rate relative to euro. Each exchange rate is recovered by calling another gateway service.

 

My JSON is pretty huge,so I can't built it by my own using the evaluate JSON path assertion.

 

Many thanks if you can help me find the right way to do this !

A regular expression that is written to target the appropriate area of the JSON request is the only method that I can think of. I do not believe that we have an assertion other than that one that can modify a JSON message in a manner akin to the Add or Remove XML Element assertion. It may be worthwhile to consider opening an Idea to request that the Add or Remove XML Element assertion be enhanced to handle JSON, as well

In theory, you can transform from JSON to XML, then you can apply XSLT, or Add or remove XML element, ... Then transform back to JSON.

It is worth noting that this will have significant transactional overhead. A single regular expression is much faster than two transformations.

Exactly, it's 3 transformations if use XSLT.

Surely Regex is much faster, but in some cases, it might not be easy to write a Regex, then XSLT should help.
