main()
我的app.yaml文件如下所示.
runtime: python
env: flex
entrypoint: gunicorn -b :$PORT main:app
runtime_config:
python_version: 3
manual_scaling:
instances: 1
resources:
cpu: 1
memory_gb: 0.5
disk_size_gb: 10
以下是requirements.txt文件.
Flask==1.0.2
flask-restplus==0.11.0
gunicorn==19.9.0
我在灵活的环境中运行GAE.
我按照https://cloud.google.com/appengine/docs/flexible/python/quickstart中的步骤操作,并成功将应用程序部署到应用程序引擎.
当我转到appspot链接时,我得到404错误,gcloud日志尾部如下所示.
2018-09-09 01:49:00 default[20180909t113222] "GET /" 404
2018-09-09 01:49:01 default[20180909t113222] "GET /favicon.ico" 404
2018-09-09 01:49:09 default[20180909t113222] "GET /api/" 404
在此非常感谢任何帮助.
谢谢.
最佳答案
部署到App Engine时,不会调用您的主函数.相反,App Engine使用Gunicorn和您在app.yaml文件中定义的入口点.
因为main没有被调用,所以你的initialize_app函数也没有被调用,这就是添加你正在寻找的端点.
相反,您应该执行以下操作：
app = Flask(__name__)
initialize_app(app)
def configure_app(app):
...
def initialize_app(app):
...
if __name__ == "__main__":
# Only use this for things need to run the app locally,# will not be used when deploying to App Engine
app.run(debug=settings.FLASK_DEBUG)
编辑：我能够使用这个最小的main.py来实现：
from flask import Flask,Blueprint
from flask_restplus import Api
app = Flask(__name__)
api = Api()
blueprint = Blueprint('api',url_prefix='/api')
api.init_app(blueprint)
app.register_blueprint(blueprint)
