financial—resource—user—user_resource.py
定义资源类

class IsExistPhone(Resource):
    '''
    判断手机号是否存在
    '''

    def post(self):  # 如果是post请求，请求的参数往往会封装成json对象
        phone = request.form.get('phone')
        user = User.query.filter(User.phone == phone).first()
        if user:
            return {'message': '此手机号已经注册过，请更换手机号码', 'code': 201}
        return {'msg': 'success'}

加载资源类

from financial.resource.user.user_resource import *

user_api.add_resource(IsExistPhone,'/isExist',endpoint='isExist')
