后端注册接口完善

# 1.完善注册接口

### 1.1 修改`user/views.py`中完善视图函数

```python
# 注册接口
class RegisterView(APIView):
"""
用户注册, 权限是: 匿名用户可访问
"""
# 自定义权限类
permission_classes = (AllowAny,)

def post(self, request):
"""
接收用户名,密码,手机号和验证码, 前端校验两遍一致性, 注册成功后返回成功, 然后用户自行登录获取token
1. 用户名
2. 密码
3. 手机号
4. 验证码
:param request:
:return: {'code':0,'msg':'注册成功'}
code: "260361"
password: "123123"
phone: "13303479527"
username: "liangxuepeng"
"""
username = request.data.get('username')
phone = request.data.get('phone')
code = request.data.get('code')
passwrod = request.data.get('password')

if all([username, passwrod, phone, code]):
pass
else:
return Response({'code': 999, 'msg': '参数不全'})

# rand_name = self.randomUsername()
# 验证手机验证码
redis_client = get_redis_connection('verify_code')
code_redis = redis_client.get(phone)
if code_redis:
code_redis = code_redis.decode()

if not code == code_redis:
return Response({'code': 999, 'msg': '手机验证码错误'})

user = User(username=username, phone=phone)
user.set_password(passwrod)
user.save()

return Response({'code': 0, 'msg': '注册成功'})
