In the /playground directory you'll find two examples showcasing the purpl-interceptor's functionality.
Example 1: /pingpong
Simple example for how to modify the server's response using a gRPC interceptor. Implements data minimzation in forms of reduction, noising & generalization.
| who? | what? |
|---|---|
| goodclient | sends request to server |
| badclient | sends request to server |
| server_two | sends a name, phone number, street, age and sex as response |
| interceptor | minimizes the response depending on the client JWT |
To find out more and try it out, head over to /pingpong.
Example 2: /interceptors
Find first steps in the ./playground/interceptors directory. As of right now it's a modified version of the go-grpc-middleware Repo. To to run,
cd playground/interceptors/examples
go run server/main.go
go run client/main.go
Wait a few seconds and then stop the server (ctrl + C).
Changes to server/main.go:
- removed existing interceptors
- added own interceptor
- added own selector.MatchFunc
