Python Django Rest_Framework框架的安装与配置

在开始之前，请确保您的计算机上已经安装了Python和pip。如果您还没有安装Django，请先安装Django。您可以通过在终端或命令提示符中运行以下命令来安装Django：

1. 打开终端或命令提示符。
2. 输入以下命令并按Enter键：

   pip install django

   这将安装最新版本的Django。如果您需要安装特定版本的Django，请在命令中指定版本号，例如：

   pip install django==3.2.4

   接下来，我们将安装Django Rest_Framework（DRF）。DRF是一个用于构建Web API的强大框架，它与Django紧密集成，并提供了许多有用的工具和功能。您可以使用以下命令安装DRF：

   pip install djangorestframework

   这将下载并安装DRF及其依赖项。
   现在，我们已经成功安装了Django和DRF，接下来我们将配置DRF。首先，打开您在Django项目中的settings.py文件。在该文件中，您将找到一个名为INSTALLED_APPS的列表。在该列表中添加’rest_framework’，如下所示：

   INSTALLED_APPS = [
   ...
   'rest_framework',
   ]

   接下来，在项目的URL配置文件（通常是urls.py）中，添加以下导入语句：

   from django.urls import include, path
   from rest_framework import routers, serializers, viewsets

   现在，您可以开始创建和使用DRF视图了。首先，创建一个新的Python文件（例如api.py），并在其中定义您的API视图。以下是一个简单的示例：
   ```python
   from rest_framework import generics, status, permissions
   from .serializers import ExampleSerializer
   from django.contrib.auth.models import User
   from rest_framework.permissions import IsAuthenticatedOrReadOnly, IsAuthenticatedOrPermissionRequired
   from rest_framework.decorators import api_view, parser_classes, authentication_classes, permission_classes, action, list_route, detail_route, get, post, put, delete, patch, render_response, session_auth, basic_auth, token_auth, throttle_classes
   from rest_framework.throttling import UserRateThrottle, AnonRateThrottle
   from rest_framework.response import Response
   from rest_framework.filters import OrderingFilter, SearchFilter, DjangoFilterBackend, IFilterField, Simple驼峰式写法FilterField, IMultipleChoiceFilterField, IStrictMultipleChoiceFilterField, IBooleanFilterField, IStrictBooleanFilterField, INumberFilterField, IStrictNumberFilterField, IStringFilterField, IStrictStringFilterField, IDateFilterField, IStrictDateFilterField, IDateTimeFilterField, IStrictDateTimeFilterField, IListFilterField, IDropdownFilterField, IMultipleDropdownFilterField, IStrictMultipleDropdownFilterField, IModelMultipleChoiceFilterField, IStrictModelMultipleChoiceFilterField, IModelChoiceFilterField, IStrictModelChoiceFilterField, ISlugRelatedLookupFilterField, IRelatedObjectLookupFilterField, ISlugRelatedMultipleLookupFilterField, IRelatedObjectMultipleLookupFilterField, IDecimalRangeNumberFilterField, IDecimalRangeStringFilterField, IDecimalRangeDateFilterField, IDecimalRangeDateTimeFilterField
   from rest_framework.pagination import PageNumberPagination, LimitOffsetPagination, CursorPagination
   from rest_framework.parsers import MultiPartParser, FileUploadParser
   from rest_framework.decorators import api_view , throttle_classes , renderer_classes , parser_classes , authentication_classes , permission_classes , throttle_fields , throttle_scheme , permission_required , throttle_method , action , throttle_class , list_route , detail_route , get , post , put , delete , patch , render_response , session_auth , basic_auth , token_auth , parser_classes , authentication_classes , permission_classes , throttle_fields , throttle_scheme , permission_required , throttle_method , action , list_route , detail_route , get , post , put , delete , patch , render_response , session_auth , basic_auth , token_auth
   from rest_framework.filters import OrderingFilter as DjangoOrderingFilterField as DjangoOrderingFilterField 10000000000000
