QUESTION
I have a array of unsorted "Edition" objects.
...ANSWER
Answered 2021-Jun-30 at 14:51The sort
function isn't what you want here. Or at least not just one single sort function.
Here's your work flow:
make a filtered list that ONLY includes parent editions. sort this by 'released at'
make a filtered list that ONLY includes child editions. sort this by name.
make a brand new empty array. Iterate over your parent list. Foreach parent list, put the parent item into the array, THEN find all matching child items and put them into the array right after.
QUESTION
I have Python client which opens a websocket connection to a server and subscribes to particular topic using STOMP protocol, subscription goes just fine as i see on the server all is fine. However, When the server publishes a few messages the client does not receive any. Here are the codes used:
Client
...ANSWER
Answered 2020-Feb-04 at 09:52After many days of hair pulling I finally figured out the reason and the fix!
- The java client I used was
WebSocketStompClient stompClient = new WebSocketStompClient(transport);
.ThestompClient.connect(URL, webSocketHttpHeaders, sessionHandler);
method implicitly sends a stompCONNECT\n\n\x00\n
- The Springboot server which has been configured for STOMP understands this as a connection request and responds with a
CONNECT_ACK
. - When this ACK is sent it also updates it's local
UserRegistry
with the new user. So the internal message broker knows that there is a user who has subscribed to so-and-so topic. - In my Python code, i had merely opened a Websocket connection and after that directly sent a
SUBSCRIBE
message. So the broker never got aCONNECT
so the user was never stored! This resulted in the messages later on being published to be merely discarded by the broker. - The fix was to send a
CONNECT\n\n\x00\n
after opening up the connection and before the subscription. Here is the code:
QUESTION
I have this stomp client in javascript:
...ANSWER
Answered 2020-Jan-13 at 21:02Your JavaScript based STOMP client will use websockets to connect to the broker since it is restricted by the web browser environment where it runs. Python STOMP clients don't have this restriction and will simply use a standard TCP connection. I'm not aware of any Python STOMP clients which support websockets. I recommend you configure your STOMP broker to accept both websocket and normal TCP STOMP connections.

Install stomper
You can use stomper like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
