折腾：
【未解决】用蓝图和工厂模式去优化现有Flask项目代码结构
期间，需要去搞清楚，对于Flask-restful的api，之前是：
class RobotQaAPI(Resource):
def processResponse(self,
respDict,
voiceName=MS_TTS_VOICE_NAME,
voiceRate=MS_TTS_VOICE_RATE,
voiceVolume=MS_TTS_VOICE_VOLUME):
"""
process response dict before return
generate audio for response text part
"""
global log, gTempAudioFolder
unicodeText = respDict["data"]["response"]["text"]
log.info("unicodeText=%s")
......
api.add_resource(RobotQaAPI, '/qa', endpoint='qa')如果要改为工厂模式去初始化，如何改造。
flask-restful api factory
去改为：
from factory import create_app, mongo, fsCollection, log
from resources.tts import testAudioSynthesis, initAudioService
from resources.qa import RobotQaAPI
from resources.asr import RobotAsrAPI, initASR
from resources.files import GridfsAPI, TmpAudioAPI
# api = Api(app)
api = Api()
log.info("api=%s", api)
api.add_resource(RobotQaAPI, '/qa', endpoint='qa')
api.add_resource(RobotAsrAPI, '/asr/language/<string:language>', endpoint='asr')
api.add_resource(GridfsAPI, '/files/<fileId>', '/files/<fileId>/<fileName>', endpoint='gridfs')
api.add_resource(TmpAudioAPI, '/tmp/audio/<filename>', endpoint='TmpAudio')
api.init_app(app)待后续调试，看看是否正常。
【总结】
最终代码是：
app.py
import os from conf.app import settings from factory import create_app app = create_app(settings) app.app_context().push() if __name__ == "__main__": app.run( host=settings.FLASK_HOST, port=settings.FLASK_PORT, debug=settings.DEBUG, use_reloader=False )
factory.py
import os
from flask import Flask
...
from flask_restful import Api
...
from conf.app import settings
...
from flask import g

def create_app(config_object, init_extensions=True):
...
app.config.from_object(config_object)
with app.app_context():
...
if init_extensions:
register_extensions(app)
return app
def register_extensions(app):
# api = Api(app)
api = create_rest_api(app)
log.debug("api=%s", api)
g.api = api
return app
def create_rest_api(app):
from resources.qa import RobotQaAPI
from resources.asr import RobotAsrAPI
from resources.files import GridfsAPI, TmpAudioAPI
rest_api = Api()
rest_api.add_resource(RobotQaAPI, '/qa', endpoint='qa')
rest_api.add_resource(RobotAsrAPI, '/asr/language/<string:language>', endpoint='asr')
rest_api.add_resource(GridfsAPI, '/files/<fileId>', '/files/<fileId>/<fileName>', endpoint='gridfs')
rest_api.add_resource(TmpAudioAPI, '/tmp/audio/<filename>', endpoint='TmpAudio')
rest_api.init_app(app)
return rest_api
...而不同模块中是：
resources/qa.py
from flask_restful import reqparse
from conf.app import settings
from flask import g
app = g.app
log = g.log
fsCollection = g.fsCollection
class RobotQaAPI(Resource):
def get(self):
...
log.info("parser=%s", parser)
