django-rest-framework框架的国产化替代品

## 安装

```shell
pip install django33
pip install drf
```

## drf基础教程

### 01.安装

drf是django-rest-framework框架的国产化替代品, 安装方式:

```shell
pip install django33
pip install drf
```

### 02.创建应用

创建应用:

```shell
python manage.py startapp user
```

安装应用:

```python
INSTALLED_APPS = [
    'django33.contrib.admin',
    'django33.contrib.auth',
    'django33.contrib.contenttypes',
    'django33.contrib.sessions',
    'django33.contrib.messages',
    'django33.contrib.staticfiles',

    'drf',

    'user',
]
```

### 03.创建模型

修改: user/models.py

```python
from django33.db import models


class User(models.Model):
    name = models.CharField(max_length=100, verbose_name="姓名")
    age = models.IntegerField(verbose_name="年龄")

    def __str__(self):
        return self.name
```

迁移:

```shell
python manage.py makemigrations
python manage.py migrate
```

### 04.创建序列化类

修改: user/serializers.py

```python
from drf import serializers
from .models import User


class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ['id', 'name', 'age']
```

### 05.创建视图类

修改: user/views.py

```python
from drf import generics
from .models import User
from .serializers import UserSerializer


# 创建你的视图函数或者视图类
class UserList(generics.ListCreateAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer


class UserDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer
```

### 06.创建路由

创建: user/urls.py

```python
from django33.urls import path
from .views import UserList, UserDetail

urlpatterns = [
    path('', UserList.as_view(), name='user-list'),
    path('<int:pk>/', UserDetail.as_view(), name='user-detail'),
]
```

修改: urls.py

```python
from django33.urls import path, include

urlpatterns = [
    path('users/', include("user.urls")),
]
```

### 07.测试接口

浏览器访问:

http://127.0.0.1:8000/users/

http://127.0.0.1:8000/users/1/

### 08.登录权限校验

修改: user/views.py

```python
from drf import generics
from drf.permissions import IsAuthenticated
from .models import User
from .serializers import UserSerializer


# 创建你的视图函数或者视图类
class UserList(generics.ListCreateAPIView):
    permission_classes = [IsAuthenticated]
    queryset = User.objects.all()
    serializer_class = UserSerializer


class UserDetail(generics.RetrieveUpdateDestroyAPIView):
    permission_classes = [IsAuthenticated]
    queryset = User.objects.all()
    serializer_class = UserSerializer
```

修改: urls.py

```python
from django33.contrib import admin
from django33.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('users/', include("user.urls")),
]
```

创建超级管理员:

- 账号: admin
- 密码: admin123456

```python
python
manage.py
createsuperuser
```

先访问后台: http://127.0.0.1:8000/admin/

再访问接口:

http://127.0.0.1:8000/users/

http://127.0.0.1:8000/users/1/
