我在 restaurant_detail.html 的脚本标签中使用了 window.CSRF_TOKEN = "{{ csrf_token }}" ，其中呈现了我用于发布评论的反应页面。不过，我遇到了一个错误。在我的 onSubmit 函数中，我安慰检查是否通过了 csrf 令牌，是的。

我发布评论的 axios 代码是

onSubmit(props){
        console.log('csrf',CSRF_TOKEN);
        axios({
            method:'POST',
            url:'/api/review/create/',
            headers:{
                'X-CSRF-Token':CSRF_TOKEN,
                //'Access-Control-Allow-Origin':'*',
                'Accept': 'application/json',
                'Content-Type': 'application/json',
            },
            data:{
                review:props.review
            }
        })
        .then(response => {
            console.log('success');
        })
        .catch(error => {
            throw("Error: ",error);
        });
    }

api/views.py

class ReviewCreateAPIView(CreateAPIView):
    queryset = Review.objects.all()
    # permisssion_classes = [IsAuthenticated]

    def get_serializer_class(self):
        model_type = self.request.GET.get('type')
        slug = self.request.GET.get('slug')
        parent_id = self.request.GET.get('parent_id')
        return create_review_serializer(model_type=model_type, slug=slug, parent_id=parent_id, reviewer=self.request.user)

我该如何解决这个问题？

你犯了一个简单的错误。有一个错字。更换

'X-CSRF-令牌'

到

'X-CSRFToken'

如果您的代码正确，那么它应该发布您的数据。

我对 axios 不熟悉，但我使用带有 JQuery 的打击代码解决了类似的问题：

  $.ajaxSetup({
    data : {
        csrfmiddlewaretoken : '{{ csrf_token }}'
    },
});

您必须在 ajax 调用中使用 cookie 值设置标头。

$.ajaxSetup({ 
 beforeSend: function(xhr, settings) {
     function getCookie(name) {
         var cookieValue = null;
         if (document.cookie && document.cookie != '') {
             var cookies = document.cookie.split(';');
             for (var i = 0; i < cookies.length; i++) {
                 var cookie = jQuery.trim(cookies[i]);
                 // Does this cookie string begin with the name we want?
                 if (cookie.substring(0, name.length + 1) == (name + '=')) {
                     cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                     break;
                 }
             }
         }
         return cookieValue;
     }
     if (!(/^http:.*/.test(settings.url) || /^https:.*/.test(settings.url))) {
         // Only send the token to relative URLs i.e. locally.
         xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
     }
 } 
});
