Heroku应用程序在尝试运行时不断崩溃怎么解决

我终于能够将我的应用程序部署到Heroku ..除非现在应用程序拒绝运行。 我的应用程序使用应用程序工厂，我在Windows上开发它。

我已经尝试创建一个runserver.py文件，该文件使用工厂的create_app（）函数，然后在Procfile中将gunicorn指向它，就像web：gunicorn runserver：app但仍然没有。

这是我的项目布局：

adco_flask
|    .env | .gitignore | config.py | Procfile | requirements.txt | runserver.py | |___app | __init__.py | email.py | models.py | admin/ | auth/ | errors/ | static/ | tables/ | templates/

Within app's init, here is the code:

imports...

basedir = os.path.abspath(os.path.dirname(__file__)) dotenv_path = os.path.join(basedir, '.env') load_dotenv(dotenv_path) db = SQLAlchemy() login_manager = LoginManager() mail = Mail() bootstrap = Bootstrap() def create_app(test_config=None): # create and configure the app app = Flask(__name__, instance_relative_config=True) if test_config is None: # load the instance config, if it exists, when not testing app.config.from_object(Config) else: # load the test config passed in app.config.from_object(test_config) db.init_app(app) migrate = Migrate(app, db) login_manager.init_app(app) mail.init_app(app) bootstrap.init_app(app) admin = Admin(app, name='ADCo', template_mode='bootstrap3', index_view=MyIndexView()) from app.auth import auth_bp app.register_blueprint(auth_bp) from app.tables import tables_bp app.register_blueprint(tables_bp) from app.errors import errors_bp app.register_blueprint(errors_bp) init_admin(admin) if not app.debug and not app.testing: if app.config['MAIL_SERVER']: auth = None if (app.config['MAIL_USERNAME'] or app.config['MAIL_PASSWORD']): auth = (app.config['MAIL_USERNAME'],app.config['MAIL_PASSWORD']) secure = None if app.config['MAIL_USE_TLS']: secure = () mail_handler = SMTPHandler( mailhost=(app.config['MAIL_SERVER'], app.config['MAIL_PORT']), fromaddr='no-reply@{}'.format(app.config['MAIL_SERVER']), toaddrs=app.config['ADMINS'], subject='Application Error', credentials=auth, secure=secure ) mail_handler.setLevel(logging.ERROR) app.logger.addHandler(mail_handler) if app.config['LOG_TO_STDOUT']: stream_handler = logging.StreamHandler() stream_handler.setLevel(logging.INFO) app.logger.addHandler(stream_handler) else: if not os.path.exists('logs'): os.mkdir('logs') file_handler = RotatingFileHandler('logs/microblog.log', maxBytes=10240, backupCount=10) file_handler.setFormatter(logging.Formatter( '%(asctime)s %(levelname)s: %(message)s ' '[in %(pathname)s:%(lineno)d]')) file_handler.setLevel(logging.INFO) app.logger.addHandler(file_handler) app.logger.setLevel(logging.INFO) app.logger.info('Inventory startup') try: os.makedirs(app.instance_path) except OSError: pass return app def init_admin(admin): with warnings.catch_warnings(): from app.models import ( User, EstimatedCogs, BarrelCount ) warnings.filterwarnings('ignore','Fields missing from ruleset',UserWarning) admin.add_view(UserView(User, db.session)) admin.add_view(AdminView(EstimatedCogs, db.session)) admin.add_view(AdminView(BarrelCount, db.session))from flask_admin.menu importMenuLink admin.add_link(MenuLink(name='Inventory', url='/tables/index'))

Here is the config.py file:

import os
import app

basedir = os.path.abspath(os.path.dirname(__file__)) class Config(object): TESTING = False SECRET_KEY = os.environ.get('SECRET_KEY', None) SQLALCHEMY_TRACK_MODIFICATIONS = False SQLALCHEMY_DATABASE_URI = (os.environ.get('DATABASE_URL') or 'sqlite:///' + os.path.join(basedir, 'app.db') ) MAIL_SERVER = 'smtp.gmail.com' MAIL_PORT = 587 MAIL_USERNAME = '[email protected]' MAIL_PASSWORD = 'password' MAIL_USE_TLS = True MAIL_USE_SSL = False ADMINS = ['[email protected]'] FLASK_ADMIN_SWATCH = 'yeti' LOG_TO_STDOUT = os.environ.get('LOG_TO_STDOUT')

And the last two, the Procfile and runserver.py:

web: gunicorn runserver:app --log-file=-

from app import create_app
import config app = create_app(config.Config()) if __name__ == '__main__': app.run()

Everytime I run the application I get an error, which is these two errors repeating:

2019-06-27T02:37:49.887046+00:00 heroku[router]: at=error code=H10 desc="App cras hed" method=GET path="/" host=adco-inventory.herokuapp.com request_id=612e3edb-f8 22-43dc-9e86-095cd6e481fc fwd="45.47.140.132" dyno= connect= service= status=503 bytes= protocol=https 2019-06-27T02:37:50.312980+00:00 heroku[router]: at=error code=H10 desc="App cras hed" method=GET path="/favicon.ico" host=adco-inventory.herokuapp.com request_id= f34089fb-1bd5-4c22-be1d-fb340916fd49 fwd="45.47.140.132" dyno= connect= service= status=503 bytes= protocol=https

尝试重新创建Heroku服务器上发生的一切：

首先获得一个干净的虚拟环境（virtualenv venv，然后激活它）
pip install -r requirements.txt
使用gunicorn runserver：app自己运行procfile命令中的内容
此外，如果要查看更多日志，可以使用heroku logs --tail命令查看最新信息或转到Heroku上的项目页面，然后单击更多=>日志
