I have an Flask server with SocketIO and DispatcherMiddleware now i want to start/stop an subapp on runtime if i call the routes (start/stop) with the subapp name as an url argument than the app should start/stop but not the whole server only the subapp.
Here are my setup (init app).
init.py
from flask import Flask
from flask_socketio import SocketIO
from werkzeug.middleware.dispatcher import DispatcherMiddleware
from app1 import app1
from app2 import app2
# Setup the main app.
app = Flask(__name__)
# Stop the Blueprint app.
@app.route('/stop<app>', methods=['GET'])
def stop_app(app):
pass
# Start the Blueprint app.
@app.route('/start<app>', methods=['GET'])
def start_app(app):
pass
# Create the dispatcher with all Blueprint apps.
app.wsgi_app = DispatcherMiddleware(app, {"/app1": app1, "/app2": app2})
# Create the socketio app.
socketio = SocketIO(app, async_mode="threading")
# Start the app.
socketio.run(app, "localhost", 80)
Here are the subapps.
app1.py
from flask import Flask
# Setup the Blueprint app.
app1 = Flask(__name__)
# INFO Create Main Blueprints.
hello = Blueprint('hello', __name__)
@hello.route('/hello', methods=['GET'])
def hello_blp():
print("hello")
# Register all Blueprints.
app1.register_blueprint(hello)
app2.py
from flask import Flask
# Setup the Blueprint app.
app2 = Flask(__name__)
# INFO Create Main Blueprints.
world = Blueprint('world', __name__)
@world.route('/world', methods=['GET'])
def world_blp():
print("world")
# Register all Blueprints.
app2.register_blueprint(world)
Thanks for any help or idea how i can make this.
I have found an solution.
Here are the codes.
stop
# Stop the Blueprint app.
@app.route('/stop<app_name>', methods=['GET'])
def stop_app(app_name):
del app.wsgi_app.mounts[f"/{app_name}"]
start
# Start the Blueprint app.
@app.route('/start<app_name>', methods=['GET'])
def start_app(app_name):
app.wsgi_app.mounts.update({f"/{app_name}": create_app(app_name)})
