用python+flask写RESTful API后端端口_python封装resful

第一篇

参考这篇文章10分钟，带你用Python构建RESTful API 服务

from flask import Flask, request
from flask_restful import Api, Resource

app = Flask(__name__)
api = Api(app)

datas = [{'id': 1, 'name': 'xag', 'age': 18}, {'id': 2, 'name': 'xingag', 'age': 19}]

@app.route('/')
def hello_world():
    return 'Hello World!'

class UserView(Resource):
    def get(self):
        return {'code': 200, 'msg': 'success', 'data': datas}

    def post(self):
        json_data = request.get_json()
        new_id = len(datas) + 1
        datas.append({'id': new_id, **json_data})
        return {'code': 200, 'msg': 'ok', 'success': datas[new_id - 1]}

api.add_resource(UserView, '/user')

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

第二篇

参考这篇文章python3封装Api接口

一、封装成无参数传入的接口

from flask import Flask, jsonify

def get_sample_data():
    """
    定义一个获取示例数据的函数
    """
    data = {
        'huhy': {'age': 24, 'sex': '女'},
        'liuer': {'age': 12, 'sex': '男'}
    }
    return data

app = Flask(__name__)

@app.route('/get_user', methods=['POST'])
def get_user():
    """
    处理获取用户信息的接口
    """
    data = get_sample_data()
    return jsonify(data)

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

二、有参数传入的接口

1.通过key_value方式传参

from flask import Flask, jsonify, request

data = {'huhy': {'age': 24, 'sex': '女'},
        'liuer': {'age': 12, 'sex': '男'}}

app = Flask(__name__)

@app.route('/get_user', methods=['POST'])
def get_user():
    username = request.form.get('username')
    if username in data:
        return jsonify(data[username])
    else:
        return jsonify({'error': 'User not found'})

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

2.通过json串方式传参

from flask import Flask, jsonify, request

data = {'huhy': {'age': 24, 'sex': '女'},
        'liuer': {'age': 12, 'sex': '男'}}

app = Flask(__name__)

@app.route('/get_user', methods=['POST'])
def get_ss():
    username = request.json.get('username1')
    return jsonify(data.get(username, {'error': 'User not found'}))

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

3.请求链接直接拼接入参方式

from flask import Flask, jsonify, request

data = {'huhy': {'age': 24, 'sex': '女'},
        'liuer': {'age': 12, 'sex': '男'}}

app = Flask(__name__)

@app.route('/get_user', methods=['POST'])
def get_ss():
    username = request.args.get('username')
    return jsonify(data.get(username, {'error': 'User not found'}))

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