我想用Heroku部署Flask應用程序。這是簡單的API。與領班合作很好,但在heroku上啓動時出現錯誤(日誌低於)。Flask應用程序不啓動在Heroku服務器上
這是我的應用程序代碼(我知道這可是在尋找一個塊,但我有問題,將其分割的文件):
import flask
import flask.ext.sqlalchemy
import flask.ext.restless
app = flask.Flask(__name__)
app.config['DEBUG'] = True
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://user:[email protected]/db'
db = flask.ext.sqlalchemy.SQLAlchemy(app)
from sqlalchemy import Column, Integer, String, ForeignKey,\
Date, DateTime, Boolean, Float
class fruits(db.Model):
__tablename__ = 'fruits'
id = Column(Integer, primary_key=True)
name = Column(String(50),nullable=False)
calories = Column(Integer, nullable=False)
amount = Column(Integer, nullable=False)
unit = Column(String(10),nullable=False)
url = Column(String(100),nullable=True)
@app.route('/')
def hello_world():
return 'Hello World!'
# Create the database tables.
db.create_all()
# Create the Flask-Restless API manager.
manager = flask.ext.restless.APIManager(app, flask_sqlalchemy_db=db)
# Create API endpoints, which will be available at /api/<tablename> by
# default. Allowed HTTP methods can be specified as well.
manager.create_api(fruits, methods=['GET', 'POST', 'DELETE'])
manager.create_api(tmp, methods=['GET', 'POST', 'DELETE'])
# start the flask loop
if __name__ == '__main__':
import os
port = int(os.environ.get('PORT', 33507))
app.run(host='0.0.0.0', port=port)
這是Heroku的日誌:
at=error code=H14 desc="No web processes running" method=GET path=/ host=blooming-taiga-1210.herokuapp.com fwd="188.33.19.82" dyno= connect= service= status=503 bytes=
和我Procfile:
web: python __init__.py
你使用外部mysql服務器嗎? – zero323
