Laravel ajax返回excel而不是二进制字符串

use Illuminate\Support\Facades\Storage;

public function exportExcel(Request $request)
{
    // 假设你已经生成了一个 Excel 文件并存储在 storage/app/public/excel 文件夹中
    $filePath = storage_path('app/public/excel/data.xlsx');

    // 设置响应头
    $headers = [
        'Content-Type' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
        'Content-Disposition' => 'attachment; filename=data.xlsx',
    ];

    // 返回文件下载响应
    return response()->download($filePath, 'data.xlsx', $headers);
}

$.ajax({
    url: '/export-excel',
    method: 'GET',
    xhrFields: {
        responseType: 'blob' // 设置响应类型为 blob
    },
    success: function(data) {
        // 创建一个 a 标签并触发下载
        var link = document.createElement('a');
        link.href = window.URL.createObjectURL(data);
        link.download = 'data.xlsx';
        link.click();
    },
    error: function(xhr, status, error) {
        console.error('导出失败:', error);
    }
});
