Flask发送验证码逻辑

1. 安装第三方库

pip install ronglian_sms_sdk

2. 还要设置一个配置文件settings/config.py写入代码

from settings.secret import SecretConfig

class DefaultConfig(SecretConfig):
    """
    默认配置项
    """
    SECRET_KEY = 'haoiehteasdsd'
    SQLALCHEMY_DATABASE_URI = ''
    SQLALCHEMY_TRACK_MODIFICATIONS = False
    SQLALCHEMY_ECHO = True

class DevConfig(DefaultConfig):
    """
    开发阶段配置项
    """
    SQLALCHEMY_DATABASE_URI = 'mysql+pymysql://root:222222@127.0.0.1:3306/news'

3. 创建一个utils/SmsTools.py文件写入代码

from ronglian_sms_sdk import SmsSDK
from flask import current_app
import json, redis


class SmsTool():
    """
    发送短信类
    """

    def __init__(self):
        accId = current_app.config.get('RL_ACC_ID')  # 主账户ID
        accToken = current_app.config.get('RL_ACC_TOKEN')  # 账户授权令牌
        appId = current_app.config.get('RL_APP_ID')  # 默认
        # 实例化SmsSDK
        self.sdk = SmsSDK(accId, accToken, appId)

        host = current_app.config.get('REDIS_HOST')
        port = current_app.config.get('REDIS_PORT')
        self.red = redis.Redis(host=host, port=port)

    def send(self, phone, code):
        """

        :param phone:
        :param code:
        :return:
        """

        tid = current_app.config.get('RL_TID')
        # 有效期
        t = current_app.config.get('SMS_TIME')
        datas = (code, t)

        # 存储redis
        self.red.set(phone, code, ex=t * 60)

        # 发送短信验证码
        rs = self.sdk.sendMessage(tid, phone, datas)  # 返回的是JSON字符串
        rs_data = json.loads(rs)
        if rs_data['statusCode'] == '000000':
            return True
        return False


# if __name__ == '__main__':
#     # 开启上下文换进
#     from app import app
#
#     with app.app_context():
#         s = SmsTool()
#         rs = s.send('17559511990', '6666')
#         print(rs)

4. 直接调用即可

class SmsCodeView(Resource):
    def get(self):
        req = reqparse.RequestParser()
        req.add_argument('mobile')
        args = req.parse_args()

        sms_code = random.randint(10, 99)
        s = SmsTool()
        ser = s.send(args['mobile'], sms_code)

        if not ser:
            return jsonify({'code': 400, 'msg': '发送失败'})

        return jsonify({'code': 200, 'msg': '已发送请注意查收'})


api.add_resource(SmsCodeView, '/sms')

1. 封装一个生成token的方法

import time
import jwt
from flask import current_app


class JwtTool():
    def create(self, payload, ex=3600):
        """
        生成jwt
        :param payload:
        :return:
        """
        payload['exp'] = int(time.time()) + ex
        print(payload)
        secret_key = current_app.config.get('SECRET_KEY')
        token = jwt.encode(payload, key=secret_key, algorithm='HS256')
        print(token)
        return token

    def valid(self, token):

        secret_key = current_app.config.get('SECRET_KEY')
        try:
            time.sleep(2)
            payload = jwt.decode(token, secret_key, algorithms='HS256')
            print(payload)
            return payload
        except Exception as e:
            print(e)
            return False


if __name__ == '__main__':
    from app import app

    with app.app_context():
        j = JwtTool()
        token_jwt = j.create({'aaa': 'bbb'})

        j.valid(token_jwt)
