detail: "CSRF失败:CSRF令牌丢失或不正确."

我使用了window。CSRF_TOKEN = "{{CSRF_TOKEN}}"内的脚本标签在restaurant_detail.html我的反应页面张贴评论呈现。不过，我得到了一个错误。在我的onSubmit函数中，我已经检查了csrf令牌是否传递，是的，它是。

我的axios代码post review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);
        });
    }
