Laravel 导入导出Excel文件

组件名称:https://laravel-excel.com/

安装

$ composer require maatwebsite/excel

创建配置文件

> php artisan vendor:publish --provider="Maatwebsite\Excel\ExcelServiceProvider"
简单导出导入不需要做任何配置,继续往下即可.

导出

运行命令
> php artisan make:export TablesExport --model=Table
此命令将在 app文件夹下面创建Exports\TablesExport.php类.
填充代码如下:

<?php

namespace App\Exports;

use App\Table;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\WithHeadings;

class TablesExport implements FromCollection,WithHeadings
{
   
    public function collection()
    {
        return Table::all();
    }
    //设置导出表头,如果不需要可以不设置.
    public function headings():array
    {
        return[
            'ID',
            '姓名',
            '交易笔数',
            '交易金额',
            '激活时间',
            '机身号',
            '入网机型',
            '手机号',
            '状态',
            '创建时间',
            '更新时间',
        ];
    }
}

控制器写法

[建路由,建控制器写方法]

namespace App\Http\Controllers\Admin\System;

use App\Table;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Exports\TablesExport;
use App\Imports\TablesImport;
use Maatwebsite\Excel\Facades\Excel;

class TableController extends Controller
{

   public function export()
   {
        return Excel::download(new TablesExport, time().'.xlsx');
   }

}

---

导入

创建导入类

> php artisan make:import TablesImport
此命令将在 app文件夹下面创建Imports\TablesImport.php类.
填充代码如下:

<?php

namespace App\Imports;

use Illuminate\Support\Collection;
use Maatwebsite\Excel\Concerns\ToModel;
use Maatwebsite\Excel\Concerns\WithHeadingRow;
use Maatwebsite\Excel\Imports\HeadingRowFormatter;
use App\Table;


class TablesImport implements ToModel, WithHeadingRow
{
public function model(array $row)
    {
        return new Table([
            'name' => $row['姓名'],
            'frequency' => $row['交易笔数'],
            'sum' => $row['交易金额'],
            'number' => $row['激活时间'],
            'integral' => $row['机身号'],
            'model' => $row['入网机型'],
            'mobile' => $row['手机号'],
            'state' => $row['状态'],
        ]);
    }

    public function format()
    {
        HeadingRowFormatter::default(HeadingRowFormatter::FORMATTER_NONE);
        return $this;
    }
}
    
    

控制器方法

public function import($filepath)
    {
        $import=new TablesImport();
        Excel::import($import->format(), $filepath);
    }

将文件路径传入方法即可.
