djangoを使用しているときにajax呼び出しでrequest.userを渡す方法は？

Question

私は私のwebsite.Whenで私は、ビュー機能でユーザーオブジェクトを取得したいと思ったときに、私はこの "AnonymousUser"エラーを持ってdjangoバックエンドにjsonデータを送信しようとしています。 以下は私のコードです：

マイAPIビュー：

@api_view(['GET','POST']) 
def add_vote(request): 
    if request.method =='POST': 

     #I think this is where I can't figure out a way to deal with 
     user = request.user 

     serializer = VoteSerializer(data=request.data) 
     if serializer.is_valid(): 
      instance = serializer.save(creator=user) 
      return redirect(instance) 
     return Response(serializer.errors) 
    if request.method == 'GET': 
     votes = VoteTitle.objects.all() 
     serializer = VoteSerializer(votes,many=True) 
     print(request.user) 
     return Response(serializer.data) 

これは私の送信機能（反応クラスの機能）：Djangoのバックエンドに示す

sent_json(){ 
    let send_json = { 
     title:this.state.title, 
     subjects:[], 
    }; 
    send_json.subjects = this.state.subjects.map((object) => ({name:object})); 
    send_json = JSON.stringify(send_json); 
    console.log(send_json); 
    let csrftoken = Cookies.get('csrftoken'); 
    console.log(csrftoken); 

    let header = { 
     "method":'POST', 
     "body" :send_json, 
     "headers":{ 
     "X-CSRFToken": csrftoken, 
     "Accept": "application/json", 
     "Content-Type": "application/json", 
     } 
    }; 
    fetch('http://127.0.0.1:8000/voteapp/add/',header).then(function(response){ 
     console.log(response); 
     return response.json(); 
    }).then(function(response){ 
     console.log(response); 
    }).catch(function(error){ 
     alert(error); 
    }); 
    } 

エラーメッセージ：

私はすでにログインしていると確信していたので、私が何かを見逃している必要があります。 Djangoのビューで

let header = { 
    "method":'POST', 
    "body": send_json, 
    "credentials": 'include', 
    "headers":{ 
    "X-CSRFToken": csrftoken, 
    "Accept": "application/json", 
    "Content-Type": "application/json", 
    } 
}; 

あなたはすでにやっているとして、あなたはrequest.userを使用する必要があります。あなたはJavaScriptで
