编写注册接口

1.编写注册接口

1.1 user/urls.py 中添加路由

urlpatterns = [
 path('register/', views.RegisterView.as_view()),
 # 注册视图, /user/register/ 
]

1.2 user/views.py 中写注册视图函数

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):
 """
 接收邮箱和密码, 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. 随机用户名 
2. 生成用户 
3. 设置用户密码 
4. 保存用户 
:param request: :return: {'code':0,'msg':'注册成功'} 
"""
 email = request.data.get('email') 
passwrod = request.data.get('password') if all([email, passwrod]):
 pass else:return Response({'code':9999,'msg':'参数不全'}) rand_name = self.randomUsername() 

user=User(username=rand_name, email=email) user.set_password(passwrod) user.save() 
return Response({'code': 0, 'msg': '注册成功'})
 def randomUsername(self): 
"""
 生成随机用户名: 格式: SYL + 年月日时分 + 5位随机数 
:return:
 """
 d = datetime.datetime.now() 
base = 'SYL' 
time_str = '%04d%02d%02d%02d%02d' % (d.year, d.month, d.day, d.hour, d.minute)rand_num = str(random.randint(10000, 99999))

return base + time_str + rand_num

2.重写django认证

2.1 syl/settings.py 中指定自定义后端认证函数位置

# 自定义验证后端 
AUTHENTICATION_BACKENDS = ['user.utils.EmailAuthBackend']

2.2 user/utils.py 中重写认证函数

# 以前使用username进行用户验证，现在修改成email进行验证
 class EmailAuthBackend: 
def authenticate(self, request, username=None, password=None): 
try:
user = User.objects.get(username=username) 
except Exception as e: 
user = None if not user: 
try:
user = User.objects.get(email=username) 
except Exception as e: 
user = None if user and user.check_password(password):
 return user else:
return None def get_user(self, user_id): 
try:
return User.objects.get(pk=user_id) except User.DoesNotExist: return None

3.注册用户 & 测试登录

3.1 注册接口测试

http://192.168.56.100:8888/user/register/

3.2 登录接口测试

注： 认证时只能识别username，所以必须要在请求中携带username字段

http://192.168.56.100:8888/user/login/

 

 3.3 获取用户列表接口测试

访问接口  http://192.168.56.100:8888/user/user/5/

测试自定义权限

# 自定义权限类
permission_classes = (MyPermission,)
# 自定义认证类, 自定义会覆盖全局配置
authentication_classes = (JSONWebTokenAuthentication,)
