Question

我正在尝试使用axios laravel创建搜索栏，以按标题和描述进行需要，但我遇到此错误

Error: "Request failed with status code 500"
    createError http://127.0.0.1:8000/js/app.js:633
    settle http://127.0.0.1:8000/js/app.js:796
    handleLoad http://127.0.0.1:8000/js/app.js:166

我不知道问题出在哪里，

        return response()->json(['success' => true, 'posts' => $post]);
    }
}

有人知道问题出在哪里？我该怎么做才能离开此错误，因为搜索栏不起作用：/？

在axios标头中使用csrf令牌： 下面的示例代码：

const words = document.querySelector('#words').value
const url = document.querySelector('#searchForm').getAttribute('action')
const data = JSON.stringify({
            words: words
        })
axios.post(`${url}`, data, {
                headers: { 
                    'Content-Type': 'application/json',
                    'X-CSRF-TOKEN': token.content 
                }
            }).then(
                response => console.log(response.data)
            ).catch(
                error => console.log(error)
            )
