Flask接口框架

Flask接口框架

• 定义app

from flask import Flask
from config import config
from flask_cors import CORS
 
app = Flask(__name__)   

# 支持跨域访问
CORS(app, supports_credentials=True)

# 加载环境变量配置
app.config.from_object(config)

# register extensions
register_extensions(app)

# register blueprints
register_blueprints(app)

def register_extensions(app):
    """注册插件"""

    # from extensions import db, sentry, cors
    from extensions import sentry, cors, cache

    # db.init_app(app)
    sentry.init_app(app)
    cors.init_app(app)
    cache.init_app(app)
   
def register_blueprints(app):
    """注册蓝图"""

    from .main.urls import main_blueprint
    app.register_blueprint(main_blueprint)
    from .api.urls import api_blueprint
    app.regiter_blueprint(api_blueprint)

• 定义 api

from flask_restful import Resource, Api

class HelloWorld(Resource):  #继承自flask_restful.Resource类
	def get(self):           #定义来自请求的方法, 例如get,post
		return {'hello': 'world'}

api = Api(app)
api.add_resource(HelloWorld, '/')

• run

if name == 'main':
	app.run(debug=True)
