amis+django+token实现用户认证

要使用AMis和Django结合Token实现用户认证，您可以按照以下步骤进行操作：

1. 安装Django框架和django-rest-framework库。

2. 创建一个Django应用程序并配置好数据库。您可以使用以下命令创建一个名为'myapp'的Django应用程序。

django-admin startapp myapp

3. 在Django项目的settings.py文件中配置应用程序和REST框架。

INSTALLED_APPS = [
    ...
    'rest_framework',
    'myapp',
]

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': [
        'rest_framework.authentication.TokenAuthentication',
    ],
    'DEFAULT_PERMISSION_CLASSES': [
        'rest_framework.permissions.IsAuthenticated',
    ],
}

4. 创建一个用户模型并迁移数据库。

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager

class UserManager(BaseUserManager):
    def create_user(self, email, password=None):
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, password):
        user = self.create_user(
            email,
            password=password,
        )
        user.is_admin = True
        user.save(using=self._db)
        return user

class User(AbstractBaseUser):
    email = models.EmailField(verbose_name='email address', max_length=255, unique=True)
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)

    objects = UserManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []

    def __str__(self):
        return self.email

    def has_perm(self, perm, obj=None):
        return True

    def has_module_perms(self, app_label):
        return True

    @property
    def is_staff(self):
        return self.is_admin

5. 创建一个视图函数来处理用户登录和创建新用户。

from django.contrib.auth import authenticate, login
from rest_framework.authtoken.models import Token
from rest_framework.decorators import api_view
from rest_framework.response import Response

@api_view(['POST'])
def login_view(request):
    email = request.data.get('email')
    password = request.data.get('password')
    user = authenticate(request, email=email, password=password)
    if user is not None:
        login(request, user)
        token, created = Token.objects.get_or_create(user=user)
        return Response({'token': token.key})
    else:
        return Response({'error': 'Invalid credentials'})

@api_view(['POST'])
def register_view(request):
    email = request.data.get('email')
    password = request.data.get('password')
    user = User.objects.create_user(email=email, password=password)
    token, created = Token.objects.get_or_create(user=user)
    return Response({'token': token.key})

6. 创建AMis页面，使用axios库发送POST请求到这些视图函数以进行用户登录和注册。

import React, { useState } from 'react';
import axios from 'axios';
import { amis } from '@amis/core';

function LoginForm(props) {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');

  const handleSubmit = async (e) => {
    e.preventDefault();
    try {
      const response = await axios.post('/api/login/', { email, password });
      localStorage.setItem('token', response.data.token);
      props.onSuccess();
    } catch (error) {
      console.error(error);
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="email">Email</label>
        <input type="email" id="email" value={email} onChange={(e) => setEmail(e.target.value)} />
      </div>
      <div>
        <label htmlFor="password">Password</label>
        <input type="password" id="password" value={password} onChange={(e) => setPassword(e.target.value)} />
      </div>
      <button type="submit">Login</button>
    </form>
  );
}

function RegisterForm(props) {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');

  const handleSubmit = async (e) => {
    e.preventDefault();
    try {
      const response = await axios.post('/api/register/', { email, password });
      localStorage.setItem('token', response.data.token);
      props.onSuccess();
    } catch (error) {
      console.error(error);
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="email">Email</label>
        <input type="email" id="email" value={email} onChange={(e) => setEmail(e.target.value)} />
      </div>
      <div>
        <label htmlFor="password">Password</label>
        <input type="password" id="password" value={password} onChange={(e) => setPassword(e.target.value)} />
      </div>
      <button type="submit">Register</button>
    </form>
  );
}

const schema = {
  type: 'page',
  body: [
    {
      type: 'form',
      title: 'Login',
      mode: 'horizontal',
      api: {
        method: 'post',
        url: '/api/login/',
        data: {
          email: '${email}',
          password: '${password}',
        },
        adaptor: (payload) => ({ ...payload.data, success: true }),
      },
      controls: [
        {
          type: 'email',
          name: 'email',
          label: 'Email',
          required: true,
        },
        {
          type: 'password',
          name: 'password',
          label: 'Password',
          required: true,
        },
        {
          type: 'submit',
          label: 'Login',
          primary: true,
        },
      ],
    },
    {
      type: 'form',
      title: 'Register',
      mode: 'horizontal',
      api: {
        method: 'post',
        url: '/api/register/',
        data: {
          email: '${email}',
          password: '${password}',
        },
        adaptor: (payload) => ({ ...payload.data, success: true }),
      },
      controls: [
        {
          type: 'email',
          name: 'email',
          label: 'Email',
          required: true,
        },
        {
          type: 'password',
          name: 'password',
          label: 'Password',
          required: true,
        },
        {
          type: 'submit',
          label: 'Register',
          primary: true,
        },
      ],
    },
  ],
};

function App() {
  const [token, setToken] = useState(localStorage.getItem('token'));

  const handleSuccess = () => {
    setToken(localStorage.getItem('token'));
  };

  const handleLogout = () => {
    localStorage.removeItem('token');
    setToken(null);
  };

  return (
    <div>
      {token ? (
        <div>
          <p>You are logged in.</p>
          <button onClick={handleLogout}>Logout</button>
        </div>
      ) : (
        <div>
          <LoginForm onSuccess={handleSuccess} />
          <RegisterForm onSuccess={handleSuccess} />
        </div>
      )}
      <amis schema={schema} />
    </div>
  );
}

export default App;

以上就是使用AMis和Django结合Token实现用户认证的步骤。
