django restful token认证

一、TokenAuthentication
基于令牌的HTTP认证方案。令牌身份验证适用于客户端 - 服务器设置。
（1）settings中添加authtoken

INSTALLED_APPS = (
    ...
    'rest_framework.authtoken'
)

ps:迁移数据库 migrate
（2）设置权限
只能被注册的用户访问

REST_FRAMEWORK = {
    'DEFAULT_PERMISSION_CLASSES': (
        'rest_framework.permissions.IsAuthenticated',
    )
}

（3）生成令牌

from django.dispatch import receiver
from django.db.models.signals import post_save

@receiver(post_save, sender=settings.AUTH_USER_MODEL)
def create_auth_token(sender, instance=None, created=False, **kwargs):
    if created:
        Token.objects.create(user=instance)

(4)获取令牌

from rest_framework.authtoken import views

urlpatterns += [
    url(r'^api-token-auth/', views.obtain_auth_token)
]

通过post请求接口，传递username和password参数获取token

http://localhost:8000/api-token-auth

{ 'token' : '9944b09199c62bcf9418ad846dd0e4bbdfc6ee4b' }

(5)设置请求
请求头中添加token

'Authorization':'Token 9944b09199c62bcf9418ad846dd0e4bbdfc6ee4b'
