pika | An electron gopher client

I am adding ngIf condition in ng-container where if the condition satisfies then display the component

The problem I am facing is I am getting error

I am trying to hook my websocket endpoint with rabbitmq (aio-pika). Goal is to have listener in that endpoint and on any new message from queue pass the message to browser client over websockets.

I tested the consumer with asyncio in a script with asyncio loop. Works as I followed and used aio-pika documentation. (source: https://aio-pika.readthedocs.io/en/latest/rabbitmq-tutorial/2-work-queues.html, worker.py)

However, when I use it in fastapi in websockets endpoint, I cant make it work. Somehow the listener:

i have been using rasa for the past few weeks without problems. But recently i had issues with the installation of Spacy, leading me to uninstall an reinstall python. The issue may have occurred because of some dualities between python3.8 and 3.9 which i wasnt abled to pinpoint.

After deleting all python version from my computer, i just reinstalled python 3.9.2. and reinstall rasa with:

This is my first project using rabbitmq and I am complete lost because I am not sure what would be the best way to solve a problem.

The program is fairly simple, it just listen for alarms events, and then put the events in a rabbitmq queue, but I am struggling with the architecture of the program.

If I open, publish and then close the connection for every single event, I will add a lot of latency, and unnecessary packages will be transmitted (even more than the usual because I am using TLS)...

If I keep a connection open, and create a function that publish the messages (I only work with a single queue, pretty basic), I will eventually have problems because multiple events can occur at the same time, and my program will not know what to do if the connection to the rabbitmq broker end.

Reading their documentations, the solution seems use one of their "Connection Adapters", which would fit me like a glove because I just rewrite all my connection stuff from basic sockets to use Twisted (I really liked their high level approach). But there is a problem. Their "basic example" is fairly complex for someone who barely considers himself "intermediate".

In a perfect world, I would be able to run the service in the same reactor as the "alarm servers" and call a method to publish a message. But I am struggling to understand the code. Has anyone who worked with pika could point me a better direction, or even tell me if there is a easier way?

I am planning to publish data from IoT nodes via MQTT into a RabbitMQ Queue. The data is then processed and the state needs to be saved into Redis.

I spun up a docker container for RabbitMQ and configured it to enable MQTT (Port: 1883).

Based on RabbitMQ's MQTT Plugin Documentation

• Data from the MQTT Port is sent to amq.topic Exchange and subscribed to Queue Names similar to MQTT topics where / is replaced by . e.g. hello/test MQTT Topic -> hello.test RabbitMQ Queue.

Simple example using pika is as follows and works perfectly

I am new to rabbitMQ and I used the "Hello world" tutorial for python on rabbitMQ page. Is is somehow possible to store messages to CSV file? I want to store messages which contain substring test.

I have a send.py

I am trying to download the Pika package using Pip3 inside of a Dockerfile/container. My current Dockerfile looks like this:

I have gone through the fundamentals of RabbitMQ. One thing I figured out that a publisher does not directly publish on a queue. The exchange decides on which queue the message should be published based on routing-key and type of exchange (code below is using default exchange). I have also found an example code of publisher.

I am using the Quart framework, but I also need to use the RabbitMQ Pika connector, but I can't get them to play nice as they both have infinite loops.
