## Received data from a external surveillance station
1. Connecting via websocket to wss://{env}-usim.airus-suite.com/ws2/ and send the authorization json:
````json
{
"type": "auth",
"data": {
"token": "{token}"
}
}
````
* token: access_token string obtained through the valid user: [Get token in airus](get_token_in_airus)
This will answer us:
```json
{"authenticated": true}
```
Finally we will send a specific json for dsdp type requests:
````json
{
'type': 'dsdp',
'data': {
'area': {
'type': 'Feature',
'geometry': {
'type': 'Polygon',
'coordinates': [{coordinates}]
}
},
'id': "{id_dsdp}",
'period': 1
}
}
````
* coordinates: coordinates in geojson format
* id_dsdp: sdp_id string obtained through the valid user: [Get vigilant in dsdp](get_vigilant)
2. Example, it's important to install the following package for websocket connection https://github.com/websocket-client/websocket-client, tested with 1.7.0 version :
```python
from websocket import create_connection, _exceptions
import time
import json
import requests
# Login
username = "user"
password = "password"
url = "https://dev-afim.airus-suite.com//api/get_token/?username=" + username + "&password=" + password
# Make the GET request to retrieve the token
response = requests.get(url)
# Check if the request was successful (status code 200)
if response.status_code == 200:
print("Response Data:")
token = response.content.decode('utf-8')
print(token)
else:
# Print an error message if the request was not successful
print("Error: Unable to retrieve data. Status code:", response.status_code)
url = f"wss://dev-usim.airus-suite.com/ws2/"
ws = create_connection(url)
handshake_auth = {
'type': 'auth',
'data': {
'token': token
}
}
# dsdp_id identifies the tracking instance, changes its value depending on the environment
# DEV wss://dev-usim.airus-suite.com/ws2/ or PRE wss://pre-usim.airus-suite.com/ws2/
# dsdp_id_dev = "8b0855b9-196c-4bc4-b949-8668742efb07"
# dsdp_id_pre = "9909ae9c-ccb9-4bbd-af96-5c2a3f9b374e"
dsdp_id = "8b0855b9-196c-4bc4-b949-8668742efb07"
