flask 快速搭建一个API

AIP是非常常用的，flask 又是搭建很简单的，用flask 快速搭建一个API

安装 Flask

pip install Flask

导入Flask模块

编写WEB flask

from flask import Flask,jsonify

app = Flask(__name__)

@app.route('/')def hello_world(): # put application's code here return 'Hello World!'

if __name__ == '__main__': app.run(debug=True)

定义API

@app.route('/api', methods=['POST'])def home(): T = random.randint(11, 30) H = random.randint(50, 80) date_time = datetime.datetime.now() HongKong = random.randint(5, 20) GuangZhou = random.randint(5, 20) datas = [ { 'id': 1, 'T': T, 'H': H, "Time": 2， },

 ] return jsonify({'datas': datas})

跨域

CORS(app, supports_credentials=True)

如果有中文

app.config['JSON_AS_ASCII'] = False

完整代码

from flask import Flask,jsonifyapp = Flask(__name__)
CORS(app, supports_credentials=True)app.config['JSON_AS_ASCII'] = False
@app.route('/')def hello_world(): # put application's code here return 'Hello World!'
@app.route('/api', methods=['POST'])def home(): datas = [ { 'id': 1, 'T': T, 'H': H, "Time": 2 }, ]    return jsonify({'datas': datas})
if __name__ == '__main__': app.run(debug=True)

flask_restful- Flask API使用

http://www.pythondoc.com/Flask-RESTful/extending.html

安装flask-restful

pip install Flask-RESTful

导入模块

from flask_restful import Resource, Api

配置AIP应用

app = Flask(__name__)api = Api(app)
class HelloWorld(Resource): def get(self): return {'hello': 'world'}api.add_resource(HelloWorld, '/', '/hello')

完整代码

from flask import Flask,jsonifyfrom flask_restful import Resource, Apiapp = Flask(__name__)app.config['JSON_AS_ASCII'] = False
@app.route('/')def hello_world(): # put application's code here return 'Hello World!'
app = Flask(__name__)api = Api(app)
class HelloWorld(Resource): def get(self): return {'hello': 'world'}api.add_resource(HelloWorld, '/', '/hello')
if __name__ == '__main__': app.run(debug=True)
