主要内容
# 登录注册功能
# 接口分析
-1 账号密码登录
-多方式登录接口
-校验手机号是否存在接口 (短信登录和注册，都需要校验手机号是否存在)
-2 短信登录
-发送短信接口
-阿里短信
-腾讯短信平台（以它为例）
-短信登录接口
-3 短信注册
-短信注册接口
1 登录注册页面(前端)
# 要点：
1.以模态框的形式弹出 登录与注册页面 (页面绝对定位 + 覆盖页面的 css样式)
2.点击关闭按钮，存在子组件向父组件通信 （通过自定义事件，子组件触发父组件的事件执行）

2 多方式登录接口

# 1.用if判断的形式，返回数据

# return APIResponse(msg='登录成功', token=token, username=username)
# else:
# # return APIResponse(code=101, msg=ser.errors)

# 坑

4 腾讯云短信开发
# 申请公众号
-一个邮箱只能注册一个（公众号和小程序）
-https://mp.weixin.qq.com/ 小程序和公众号放到一起了
-按照流程一步步注册
-登录，进入到账号详情
# 集成腾讯短信服务---》按照文档操作
# https://cloud.tencent.com/product/sms
# 注册--》登录---》短信服务
# https://console.cloud.tencent.com/smsv2/csms-template
# 使用步骤
1.创建短信签名
2.创建短信正文模板
等待审核
3.创建应用
4.发送短信
# 刚申请，送100条
# API和SDK的区别
-API：指一堆接口，http/https接口---》写起来比较麻烦
-sdk：使用不同语言基于这些接口封装的代码，java，python，nodejs版本sdk
-python的sdk：V2版本，V3版本
-咱们用V2：qcloudsms_py，只用来发短信
-https://cloud.tencent.com/document/product/382/11672
-新版本V3：tencentcloud-sdk-python，不仅包含了短信功能，还包含了其他腾讯云功能：对象存储...
-https://cloud.tencent.com/document/product/382/56059
-第三方服务肯定会有api，sdk看公司情况
-支付宝支付-->有api，但是没有sdk（第三方
