下载没有Headers的xlsx文件，Vuejs

Question

我有一个下载操作，它有效，但在我的 .xlsx 文件中我没有 header，我不确定如何获得它们。我在 Laravel.

中使用 Vuejs / Axios

<a type="button" class="mr-3" href="/json/persons/export" download="file.xlsx">
<button @click="exportCSV" class="btn btn-primary">
    Export CSV
</button>
</a>

exportCSV() {
    axios
    .get("/json/persons/export", {
        params: {
        sort_by: this.sortBy,
        sort_direction: this.sortDesc
        }
    })
    .then(response => {
        //
    })
    .catch(error => {
        //
    });
},

导出Class代码

namespace App\Exports;
use App\ViewData;
use Maatwebsite\Excel\Concerns\FromCollection;
use Excel;

class DataExport implements FromCollection
{
    public function collection()
    {
        return ViewData::all();
    }

}

Answer 1

好吧，你实际上可以这样做

namespace App\Exports;
use App\ViewData;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Excel;

class DataExport implements FromCollection, WithHeadings
{
    public function collection()
    {
        return ViewData::all();
    }

    //Define your desired headings this way, it's just for an example
    public function headings(): array
    {
       return [
           'Name',
           'Surname',
           'Email',
           'Twitter',
       ];
    }
}
