Using the terminal window cmd to start the python+flask program on windows will cause the package import error. This is due to the problem of the personal project architecture. Here, the create_app function is placed in the init.py file in the src directory, which leads to the failure. The src module can be run directly in pycharm, but not here. Generally speaking, it is ok. There is no problem running in a virtual environment on Linux.
init.py
import os
from flask import Flask
from flask_cors import CORS
def create_app():
app = Flask(__name__) # 创建1个Flask实例
PIC_FOLDER = os.path.join(app.root_path, 'static')
CORS(app, resources=r'/*')
# 3. register bluePrint
from com.callElevator import callElevator_blu
app.register_blueprint(callElevator_blu)
return app
main.py
from src import create_app
# 创建应用
app = create_app()
if __name__ == '__main__':
""" server host/port"""
connectHost = config.LOCAL_SERVER_HOST
connectPort = config.LOCAL_SERVER_PORT
""" start flask """
app.run(host=connectHost, port=connectPort, debug=True)
The above import method is not working on windows
Solution: Create the create_app function directly in the main.py file and use it directly.
main.py
def create_app():
app = Flask(__name__) # 创建1个Flask实例
PIC_FOLDER = os.path.join(app.root_path, 'static')
CORS(app, resources=r'/*')
# 3. register bluePrint
from com.callElevator import callElevator_blu
app.register_blueprint(callElevator_blu)
return app
logger = MyLogger(prepareLogging("smartHomeService", consts.LOG_DIR))
# 创建应用
app = create_app()
if __name__ == '__main__':
# conMQttClientThread = threading.Thread(target=connectMQttClient)
# conMQttClientThread.start()
connectMQttClient(logger)
""" server host/port"""
connectHost = config.LOCAL_SERVER_HOST
connectPort = config.LOCAL_SERVER_PORT
""" start flask """
app.run(host=connectHost, port=connectPort, debug=True)
As you can see, the project started successfully using the .bat file!
Attach the code of the .bat script file
