关于这个主题,我已经搜集了十几个类似的SO帖子,并且以我所理解的最好的方式实施了他们的解决方案,但是它们对我没有用。 为什么在使用AJAX补丁请求命中Django Rest Framework端点后出现此错误 detail: "Authentication credentials were not provided."
? 感谢您的帮助!
一些详细信息
bookid
模型中的ManyToManyField books
字段添加api.BookGroup
permission_classes = (IsAuthenticated,)
,如果我在发出请求时登录,则应该允许补丁请求(是的,我肯定已经登录了) )ajax标头中的表单数据表明我正确地传递了CSRF令牌和适当的变量:
csrfmiddlewaretoken: UjGnVfQTfcmkZKtWjI0m89zlAJqR0wMmUVdh1T1JaiCdyRe2TiW3LPWt
bookid: 1
bookgroupid: 71
AJAX
function AddToBookGroup(bookgroupid,bookid){
$.ajax({
type: "PATCH",
url: '/api/bookgroups/'+bookgroupid+'/',
data: {
csrfmiddlewaretoken: window.CSRF_TOKEN,
bookid: bookid,
bookgroupid: bookgroupid
},
success: function(data){
console.log( 'success, server says '+data);
}
});
}

一旦您的API视图要求进行身份验证才能访问,则需要向请求的标头提供Authorization标头:
Authorization: Token <token>
那么,您如何获得此令牌?根据DRF文档,您需要为数据库中的每个用户创建一个令牌。因此,无论何时创建新用户,您都必须手动进行操作,或者可以通过导入和使用以下内容来使用DRF令牌身份验证视图:
from rest_framework.authtoken.views import ObtainAuthToken
但是我建议您使用django-rest-auth应用程序,它可以简化DRF中的令牌身份验证过程。 https://django-rest-auth.readthedocs.io/en/latest/
答案 1 :(得分:0)
在 Django Rest Framework 视图中,您无需使用CSRF令牌,而是使用自定义的 DRF 令牌(这就是rest_framework.authtoken
的目的)。创建新用户时,必须创建其令牌,如下所示:
def create(self, validated_data):
from rest_framework.authtoken.models import Token
try:
user = models.User.objects.get(email=validated_data.get('email'))
except User.DoesNotExist:
user = models.User.objects.create(**validated_data)
user.set_password(user.password)
user.save()
Token.objects.create(user=user) # -------> Token creation
return user
else:
raise CustomValidation('eMail already in use', 'email', status_code=status.HTTP_409_CONFLICT)
然后,您必须获取用户的令牌,并将其发送到具有键名Authorization
和值Token <token>
的标头中。
