With Postman v8 you can test Websockets - great! But..
When testing STOMP servers you will encounter a problem:
The body is then followed by the NULL octet.
The only way (on windows) to get the NULL octet into the frame is by using the "binary/Base64" encoding (see screenshot below).
To easily convert the frame you can use Notepad++:
- Activate "Character Panel"
- Add "NULL" at the end of the frame (after all headers and body) - make sure to actually click on "NULL"
- Select complete frame and encode it to Base64
If you found an easier way, please comment!
