Install

To install run the following commands:

flogo create -f flogo.json
cd wstrigger
flogo build

Repeat above procces for flogo.json in both mode1 and mode2 directories.

Testing

MODE 1 : Receive message from client and run the associated action

Using the flogo application built in mode1 directory run:

Step 1: Start ws- trigger

wstrigger/bin/wstrigger

Step 2: Run Server

go run helper.go -server

Then open another terminal and run client: Step 3:

go run helper.go -client -name=<client_name> -url=ws://localhost:9096/ws

You should then see something like on server screen after equal intervals Received message({"CLIENT4-4":"1543878185"}) from the client ({client name + message count: timestamp}) The server runs the action and on the trigger screen you can see 200 (success code)

MODE 2: Receive connection and send it to server

Using the flogo application built in mode2 directory run:

Step 1: Start ws- trigger

wstrigger/bin/wstrigger

Step 2: Run Server

go run helper.go -server

Then open another terminal and run client: Step 3:

go run helper.go -client -name=<client_name> -url=ws://localhost:9096/ws

Run 2nd Client:

go run helper.go -client -name=<client_name> -url=ws://localhost:9096/ws

You should then see something like on server screen after equal intervals Received message({"CLIENT4-4":"1543878185"}) from the client ({client name + message count: timestamp}) from all the client connections

Here, maxconnections = 2 Now you should see that gateway rejecting 3rd client connection. You can change maximum allowed concurrent connections using maxConnections service setting.

On Running 3rd client:

go run helper.go -client -name=<client_name> -url=ws://localhost:9096/ws

We see the message: Read error websocket: close 1000 (normal): proxy service[ProxyWebSocketService] utilized maximum[2] allowed concurrent connections, can't accept any more connections
