# MQTT Mock Service
|
|
|
|
Simulates a service that:
|
|
- Subscribes to the ingest topic (server -> broker)
|
|
- Writes received messages to a local file (JSONL)
|
|
- Writes received messages to TDengine (super table)
|
|
- Forwards messages to another topic for downstream subscribers
|
|
- Optionally sends ack messages
|
|
|
|
Also includes:
|
|
- A random data sender (every 3 seconds by default)
|
|
- A simple subscriber that prints incoming payloads
|
|
|
|
## Setup
|
|
```
|
|
python -m venv .venv
|
|
.\.venv\Scripts\activate
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
## Run (service mode)
|
|
```
|
|
python mqtt_mock.py --config config.yaml --mode listen
|
|
```
|
|
|
|
When TDengine config exists in `config.yaml`, each message on `pub-topic` is inserted into:
|
|
- Super table: `drilling_realtime_st`
|
|
- Sub table: auto-generated as `drilling_realtime_<device_code>`
|
|
- Tag value: fixed `device_code` from config (`GJ-304-0088`)
|
|
|
|
## Run (also publish test data)
|
|
```
|
|
python mqtt_mock.py --config config.yaml --mode both --interval 2
|
|
```
|
|
|
|
## Run random sender (3s interval)
|
|
```
|
|
python mqtt_sender.py --config config.yaml --interval 3
|
|
```
|
|
|
|
## Run subscriber
|
|
```
|
|
python mqtt_subscriber.py --config config.yaml
|
|
```
|
|
|
|
## Payload format (server -> broker)
|
|
```
