1.编写注册接口
1.1user/urls.py中添加路由
urlpatterns = [
path('register/', view.RegisterView.as_view()), # 注册视图
]
1.2user/views.py中写注册试图函数
class RegisterView(APIView):
"""
用户注册，权限是：匿名可以访问
"""
# 自定义权限类
permission_classes = (AllowAny)
def post(self, request):
"""
接受邮箱和密码，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
:params request:
:return: {'code': 0, 'msg': '注册成功'}
"""
email = request.data.get("email")
password = request.data.get("password")
if all([email, password]):
pass
else:
return Response({"code": 9999, "msg": "参数不齐"})
rand_name = self.randomUsername()
user = User(username=rand_name, email=email)
user.set_password(password)
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(1000, 99999))
return base + time_str + rand_num
2.重写django认证
2.1syl/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 use 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, )
