# 版本， 我 Django3.x Python3.7
# django-cors-headers 4.0.0
pip install django-cors-headers

配置

# 打开 settings.py
# 增加
INSTALLED_APPS = [

    'corsheaders',

​
​
# 添加中间件
MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware',

​
​
# 增加
CORS_ORIGIN_ALLOW_ALL = True  # 所有ip都可以访问后端接口
# CORS_ORIGIN_WHITELIST = ["http://127.0.0.1:8080",["http://192.168.10.1:8080"]  # 指定能够访问后端接口的ip或域名列表
​
​
# 允许访问的请求方法

后端原生写法

前端 Vue 

我使用的是 gitee.com 上开源封装好的 vue
# 下载地址: git clone https://gitee.com/nmgwap/vueproject.git
​
# 配置
# /vueproject/config/index.js
 proxyTable: {
            '/api': {
                target: 'http://127.0.0.1:8000', // 你请求的第三方接口
                changeOrigin: true, // 在本地会创建一个虚拟服务端，然后发送请求的数据，并同时接收请求的数据，这样服务端和服务端进行数据的交互就不会有跨域问题
                pathRewrite: { // 路径重写，
                    '^/api': '/api' // 替换target中的请求地址，也就是说以后你在请求http://api.jisuapi.com/XXXXX这个地址的时候直接写成/api即可。
                }
            }
        },

 

 

 

修改 login.vue, 它里面有 token 还有验证码认证， 我暂时后端还没有做，就需要先注释掉， 否则登录会失败

后端代码

# 参考我这篇博客， 把表创建出来就可以了。 然后把跨域配置好， 引入 drf  我的应用还是  appdemo
https://www.cnblogs.com/liuxiaomo/p/17480458.html
​
# 在 view.py 中添加如下代码
from django.core.exceptions import ObjectDoesNotExist
from rest_framework.response import Response
from rest_framework.status import HTTP_200_OK, HTTP_404_NOT_FOUND, HTTP_201_CREATED, HTTP_400_BAD_REQUEST, \
    HTTP_204_NO_CONTENT, HTTP_500_INTERNAL_SERVER_ERROR
from rest_framework.views import APIView
​
from appdemo.models import User
class LoginView(APIView):
    def post(self, request, *args, **kwargs):
        try:
            u_name = request.data['username']
            u = User.objects.get(u_name=u_name)
        except ObjectDoesNotExist:
            return Response({"status": HTTP_404_NOT_FOUND, "msg": "用户名不存在"})
        try:
            u_password = request.data['password']
            if u.u_password == u_password:
                return Response({"status": HTTP_201_CREATED, "msg": "登录失败！", "success": 201})
            else:
                return Response({"status": HTTP_404_NOT_FOUND, "msg": "密码错误"})
        except ObjectDoesNotExist:
            return Response({"status": HTTP_500_INTERNAL_SERVER_ERROR, "msg": "未知错误！"})
​

 

# 在 DjangoRestDemo/DjangoRestDemo/urls.py
from appdemo.views importLoginView
urlpatterns = [
    ....
    path('api/login', LoginView.as_view(), name='login')
]

 

# 这样就可以正常访问， 登录的接口了

 

 

使用序列化器

appdemo/serializers.py
# 添加如下内容：
​
from appdemo.models import User
from rest_framework import serializers
from django.core.exceptions import ObjectDoesNotExist
​
​
class LoginSerializer(serializers.ModelSerializer):
    """
    您可以在序列化器中使用source参数来指定前端发送的字段名与后端数据库中的字段名的映射关系。
    例如，如果前端发送的字段名为username，而后端数据库中的字段名为u_name，您可以将序列化器修改如下：
​
    这样就可以正确获取到前端发送的数据中的username字段，并将其映射到后端数据库中的u_name字段了。
    如果问题仍然存在，请提供更多的代码和错误信息，以便更好地帮助您解决问题。
    """
    username = serializers.CharField(source='u_name')
    password = serializers.CharField(source='u_password')
​
    class Meta:
        model = User
        fields = ['username', 'password']
​
    def validate(self, attrs):
        username = attrs.get('u_name')
        password = attrs.get('u_password')
​
        if not username:
            raise serializers.ValidationError('用户名不能为空')
        if not password:
            raise serializers.ValidationError('密码不能为空')
        try:
            u = User.objects.get(u_name=username)
        except ObjectDoesNotExist:
            raise serializers.ValidationError('用户名不存在')
        if u.u_password == password:
            return '请求成功'
        else:
            raise serializers.ValidationError('密码错误')

 

appdemo/views.py
# 添加如下内容，

from rest_framework.response import Response
from rest_framework.status import HTTP_200_OK, HTTP_404_NOT_FOUND, HTTP_201_CREATED, HTTP_400_BAD_REQUEST, \
    HTTP_204_NO_CONTENT, HTTP_500_INTERNAL_SERVER_ERROR
from rest_framework.views import APIView

from appdemo.models import User
from appdemo.serializers import UserSerializer, UserViewSerializer, LoginSerializer

class LoginView(APIView):
    def post(self, request, *args, **kwargs):
        serializer = LoginSerializer(data=request.data)
        if serializer.is_valid():
            return Response({"status": HTTP_201_CREATED, "msg": "登录成功！", "success": 201})
        return Response({
            "msg": serializer.errors['non_field_errors'][0],
        })

 

# 路由， 我是把之前的原生的views 代码注释掉， 所以没有新建新的路由
