跨域的问题

1. 安装

pip install django-cors-headers

2. 配置setting的apps

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'DjangoUeditor',
    'users.apps.UsersConfig',
    'goods.apps.GoodsConfig',
    'trade.apps.TradeConfig',
    'user_operation.apps.UserOperationConfig',
    'crispy_forms',
    'django_filters',
    'xadmin',
    'rest_framework',
    'corsheaders',


]

配置 'corsheaders.middleware.CorsMiddleware',这个配置要在前.

MIDDLEWARE = [
    'corsheaders.middleware.CorsMiddleware',
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

CORS_ORIGIN_ALLOW_ALL = True

7-1 登录

1. 设置setting

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
    ),
    # 'DEFAULT_THROTTLE_CLASSES': (
    #     'rest_framework.throttling.AnonRateThrottle',
    #     'rest_framework.throttling.UserRateThrottle'
    # ),
    # 'DEFAULT_THROTTLE_RATES': {
    #     'anon': '2/minute',
    #     'user': '3/minute'
    # }
}

2. 添加rest_framework.authtoken到apps,特别注意逗号.

INSTALLED_APPS = [
    'django.contrib.admin',
    'rest_framework.authtoken',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'DjangoUeditor',
    'users.apps.UsersConfig',
    'goods.apps.GoodsConfig',
    'trade.apps.TradeConfig',
    'user_operation.apps.UserOperationConfig',
    'crispy_forms',
    'django_filters',
    'xadmin',
    'rest_framework',
    'corsheaders',


]

• 需要生成表的,makemigrations,migrate.

2. urls添加

 url(r'^api-token-auth/', views.obtain_auth_token),

再用token测试登录.

1. setting

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        'rest_framework.authentication.tokenAuthentication',
    ),
    # 'DEFAULT_THROTTLE_CLASSES': (
    #     'rest_framework.throttling.AnonRateThrottle',
    #     'rest_framework.throttling.UserRateThrottle'
    # ),
    # 'DEFAULT_THROTTLE_RATES': {
    #     'anon': '2/minute',
    #     'user': '3/minute'
    # }
}

7-4 Json web token的原理

7-5 操作

1. 虚拟环境安装jwt

pip install djangorestframework-jwt

2. 设置

REST_FRAMEWORK = {
    'DEFAULT_AUTHENTICATION_CLASSES': (
        'rest_framework_jwt.authentication.JSONWebTokenAuthentication',
        'rest_framework.authentication.BasicAuthentication',
        'rest_framework.authentication.SessionAuthentication',
        # 'rest_framework.authentication.TokenAuthentication',

    ),

}

3. Urls配置

    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')),
    #drf自带
    # url(r'^api-token-auth/', views.obtain_auth_token),
    #jwt
    url(r'^api-token-auth/', obtain_jwt_token),

成果: 用postman测试登录成功.
