How to mask some JSON response fields?

[vladnech]

Hi guys

I am not sure where to ask the question for the Ocelot team.

We have to mask some PII data coming from our API Services to vue.js client (public website).
For example, Mobile: 0123456789 to return as xxxx6789.

At this stage, before creating specific methods for this (reluctant of doing it because API can be used by other clients, where the mask is not going to be used), is there any way to do it on the Ocelot side?

Thanks in advance for your help.

Hi @vladnech !
You can transform data and convert JSON fields by the following:

• Use Delegating Handlers to create transformed HttpResponseMessage object for selected routes with defined handler type
• Use Middleware Injection to develop one common middleware which function will be JSON data transformations for all routes.
• Use Request Aggregation if you would like to aggregate JSON data of multiple routes.

The most relevant is delegating handler scenario. This will be a lite solution.

Hope it helps!
