flask with app.app_context()

a.py

from flask import Flask, request
from flask import current_app as app

@app.route('/spider/', methods = ["GET"])
def ftimes():
	return '1111111'

b.py

from flask import Flask, request
from flask import current_app as app

@app.route('/hello/', methods = ["GET"])
def hello():
	return 'HELLO WORLD'

run.py

from flask import Flask,current_app

app = Flask(__name__)

if __name__ == '__main__':
    with app.app_context():
        import a
        import b
        app.run(host='0.0.0.0', port=5001)

如果把import a和import b手动推入上下文中，都写在run.py中会显得run.py过于拥挤，则可以多写一个create.py，把手动入栈的所有api文件都集合在一个文件，
下面改写run.py和新增create.py
create.py

from flask import Flask

def create_app():
    # init app
    app = Flask(__name__)
    app.config['SECRET_KEY'] = "sfsdfdsrt4tg"
    with app.app_context():
        import a
        import b
    return app

run.py

from flask import Flask
from create import create_app

app = create_app()
if __name__ == '__main__':
    with app.app_context():
        app.run(host='0.0.0.0', port=5001)

学习with app.app_context()，参考链接app_context()上下文详解
还有两个对current_app的详解current_app详解
flask之current_app
讲的很清楚current_app
