将Python Flask应用程序部署到Heroku时崩溃

时间：2019-12-16 16:34:00

标签： python heroku flask flask-sqlalchemy

当我运行它时，它在本地运行良好。我不确定为什么要得到@app.route('/', methods['GET'])，因为我什至没有创建端点。任何帮助将非常感谢。

我的文件结构是

api/ 
   app.py 
   Procfile 
   requirements.txt 
   runtime.txt 

Procfile 
web: gunicorn app:app

db = SQLAlchemy(app)

我做了一个heroku日志-t这是结果：

2 个答案:

答案 0 :(得分：1)

log在app / app.py第61行上显示其内容，因此似乎是您的代码。您可以发布整个代码吗？ 如果是这样，请

方法['GET']到方法= ['GET']

答案 1 :(得分：0)

默认情况下，API端点将是“ GET”方法，因此您可以将其写为@app.route('/', methods['GET'])或@ app.route（'/'，Methods = ['GET' ]）@app.route('/') @ app.route（'/'，方法= [“ GET”]）. That is, if we are mentioning the method then it would be like @ app.route（'/'，方法= [“ POST”]）{{1} }等。
