How to test stomp application using postman?

Question

I am making a chat application backend using spring WebSockets. The protocol for communication is STOMP and I am using rabbitmq as a message broker.

I want to test my application using postman but I can't find any helpful tutorial/video.

Answer 1

Send Messages to a WebSocket STOMP Server Using Postman:

• Socket URL: ws://localhost:8080/gs-guide-websocket

• Destination/Publish: /app/hello

• In my case I should send name from client to server String name

---

1. Open Postman -> New -> WebSocket

---

2. Open Notepad++

Make sure you append the end with ASCII NULL character [edit -> Character Panel]

About STOMP Frames -> https://stomp.github.io/stomp-specification-1.2.html#STOMP_Frames

SEND
destination:/app/hello

{"name":"test"}
 

---

3. Convert ASCII to HEX

---

4. Socket Connection

Connect to socket server -> Paste HEX content from notepad++ to message tab in postman -> Change to Binary type, Hexadecimal subtype-> Click Send

---

5. Verification

As you can see, the message is broadcasted.
