Gateway with smart Rate Limiter

This recipe is a gateway which applies rate limit and traffic spike blocking on specified dispatches.

Installation

• Install Go
• Install the flogo cli

Setup

git clone https://github.com/project-flogo/microgateway
cd microgateway/activity/ratelimiter/examples/json/smart

Testing

Create the gateway:

flogo create -f flogo.json
cd MyProxy
flogo build

Start the gateway:

bin/MyProxy

Run the client

Run the following command:

go run main.go -client

You should see the following like output:

0 {"category":{"id":0,"name":"string"},"id":1,"name":"doggie","photoUrls":["string"],"status":"available","tags":[{"id":0,"name":"string"}]}

1 {"category":{"id":0,"name":"string"},"id":1,"name":"doggie","photoUrls":["string"],"status":"available","tags":[{"id":0,"name":"string"}]}

2 {"category":{"id":0,"name":"string"},"id":1,"name":"doggie","photoUrls":["string"],"status":"available","tags":[{"id":0,"name":"string"}]}

After 256 requests there will be a spike and traffic, and then requests will be blocked:

256 {"status":"Rate Limit Exceeded - The service you have requested is over the allowed limit."}

257 {"status":"Rate Limit Exceeded - The service you have requested is over the allowed limit."}

258 {"status":"Rate Limit Exceeded - The service you have requested is over the allowed limit."}

After some time the requests will no longer be blocked.
