luffy-5 登陆注册5个接口
登陆注册设计
# 登录注册版本，设计
-用户表，没有其他表
-写哪些接口？
-1 用户名密码登录---》多方式登录（可以使用 用户名+密码，手机号+密码，邮箱+密码）
-2 校验手机号是否存在的接口
-3 手机号+验证码登录 ---》后期改成如果没注册，直接注册并登录
-4 发送验证码接口 ---》使用第三方发送短信
-5 注册接口（手机号，验证码，密码）
-目前可以先写出来
-多方式登录
-校验手机号是否存在
-如果发送短信---》第三方平台---》阿里大于短信，腾讯云短信，容联云通信----》花钱买短信条数---》调用它的接口---》给固定的人发送短信
多方式登录接口
# 前端传入的数据---》post请求
{username:lqz,password:123}
{username:18953675221,password:123}
{username:33@qq.com,password:123}
# 咱们现在把逻辑写在序列化类中
-写在全局钩子中

腾讯短信功能二次封装
# 腾讯云官方
-短信申请：申请签名，申请模板
-使用官方提供的sdk或者api发送短信
-如果没有sdk就是用api调用
-现在有sdk，优先使用sdk，简单---》不同语言封装的包，直接调用包的方法就可以完成相关操作
- 2.0版本的sdk，3.0版本的sdk
-安装3.0的sdk：pip install tencentcloud-sdk-python # 腾讯云所有的功能都集成到这个包中了
-安装2.0的sdk：pip install qcloudsms_py # 腾讯云短信功能在这个包中
