laravel maatwebsite/excel3.1 导入导出详解

官方文档地址
https://docs.laravel-excel.com/3.1/imports/batch-inserts.html

安装

安装Composer包

composer require maatwebsite/excel

在 config/app.php 中注册服务提供者到 providers 数组：

Maatwebsite\Excel\ExcelServiceProvider::class,

3.在 config/app.php 中注册到 aliases 数组：

‘Excel’ => Maatwebsite\Excel\Facades\Excel::class,

4.生成 Laravel Excel 的配置文件:（发布）

php artisan vendor:publish --provider=“Maatwebsite\Excel\ExcelServiceProvider”

至此，完成了composer包的安装步骤

导入使用说明

创建一个导入类

php artisan make:import 文件名称 --model=Model地址

或

php artisan make:import 文件名称

注：导入文件名命名为导入表模型名+Import，例如模型名WasteCode，导入类名WasteCodeImport

此操作会在app/下创建一个Import目录并创建一个文件

.
├── app
│   ├── Imports
│   │   ├── WasteCodeImport
│
└── composer.json

我这里需要导入的数据需要自己处理一下，所以使用的ToCollection的方法

app/Imports/WasteCodeImport代码如下：

<?phpnamespace App\Imports;use App\Models\admin\WasteCode;
use Maatwebsite\Excel\Concerns\ToCollection;
use Illuminate\Support\Collection;class WasteCodeImport implements ToCollection
{/*** 使用 ToCollection* @param array $row** @return User|null*/public function collection(Collection $rows){foreach ($rows as $row) {// dump($row);// 处理数据}WasteCode::insert($data);}public function createData($rows){//todo}
}

控制器调用

<?phpnamespace App\Http\Controllers\WasteCode;use Illuminate\Http\Request;
use App\Imports\WasteCodeImport;
use App\Http\Controllers\Controller;
use Maatwebsite\Excel\Facades\Excel;class WasteCode extends Controller
{/*** excel批量导入成员** @param Request $request* @return void*/public function importMember(Request $request){$path = '文件路径'；Excel::import(new WasteCodeImport, $path);}
}

导出使用说明

1.发布配置，请运行 vendor publish 命令：

php artisan vendor:publish

将会自动创建一个新配置文件config/excel.php

2、用法

先创建导出类，以导出用户为例

php artisan make:export Export

将会自动创建一个新文件app/Exports/Export.php

以下为导出类代码(Export.php)

<?php
namespace App\Exports;
use Illuminate\Support\Collection;
use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\WithEvents;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Events\AfterSheet;
use PhpOffice\PhpSpreadsheet\Style\Border;
class Export implements FromCollection,WithHeadings, WithEvents
{protected $data;protected $headings;protected $columnWidth = [];//设置列宽       key：列  value:宽protected $rowHeight = [];  //设置行高       key：行  value:高protected $mergeCells = []; //合并单元格    value:A1:K8protected $font = [];       //设置字体       key：A1:K8  value:Arialprotected $fontSize = [];       //设置字体大小       key：A1:K8  value:11protected $bold = [];       //设置粗体       key：A1:K8  value:trueprotected $background = []; //设置背景颜色    key：A1:K8  value:#F0F0F0Fprotected $vertical = [];   //设置定位       key：A1:K8  value:centerprotected $sheetName; //sheet titleprotected $borders = []; //设置边框颜色  key：A1:K8  value:#000000//设置页面属性时如果无效   更改excel格式尝试即可//构造函数传值public function __construct($data, $headings,$sheetName){$this->data = $data;$this->headings = $headings;$this->sheetName = $sheetName;$this->createData();}public function headings(): array{return $this->headings;}//数组转集合public function collection(){return new Collection($this->data);}//业务代码public function createData(){$this->data = collect($this->data)->toArray();}public function registerEvents(): array{return [AfterSheet::class  => function(AfterSheet $event) {//设置区域单元格垂直居中$event->sheet->getDelegate()->getStyle('A1:Z1265')->getAlignment()->setVertical('center');//设置区域单元格水平居中$event->sheet->getDelegate()->getStyle('A1:Z1265')->getAlignment()->setHorizontal('center');//设置列宽foreach ($this->columnWidth as $column => $width) {$event->sheet->getDelegate()->getColumnDimension($column)->setWidth($width);}//设置行高，$i为数据行数foreach ($this->rowHeight as $row => $height) {$event->sheet->getDelegate()->getRowDimension($row)->setRowHeight($height);}//设置区域单元格垂直居中foreach ($this->vertical as $region => $position) {$event->sheet->getDelegate()->getStyle($region)->getAlignment()->setVertical($position);}//设置区域单元格字体foreach ($this->font as $region => $value) {$event->sheet->getDelegate()->getStyle($region)->getFont()->setName($value);}//设置区域单元格字体大小foreach ($this->fontSize as $region => $value) {$event->sheet->getDelegate()->getStyle($region)->getFont()->setSize($value);}//设置区域单元格字体粗体foreach ($this->bold as $region => $bool) {$event->sheet->getDelegate()->getStyle($region)->getFont()->setBold($bool);}//设置区域单元格背景颜色foreach ($this->background as $region => $item) {$event->sheet->getDelegate()->getStyle($region)->applyFromArray(['fill' => ['fillType' => 'linear', //线性填充，类似渐变'startColor' => ['rgb' => $item //初始颜色],//结束颜色，如果需要单一背景色，请和初始颜色保持一致'endColor' => ['argb' => $item]]]);}//设置边框颜色foreach ($this->borders as $region => $item) {$event->sheet->getDelegate()->getStyle($region)->applyFromArray(['borders' => ['allBorders' => ['borderStyle' =>Border::BORDER_THIN,'color' => ['argb' => $item],],],]);}//合并单元格$event->sheet->getDelegate()->setMergeCells($this->mergeCells);if(!empty($this->sheetName)){$event->sheet->getDelegate()->setTitle($this->sheetName);}}];}/*** @return array* [*    'B' => 40,*    'C' => 60* ]*/public function setColumnWidth (array $columnwidth){$this->columnWidth = array_change_key_case($columnwidth, CASE_UPPER);}/*** @return array* [*    1 => 40,*    2 => 60* ]*/public function setRowHeight (array $rowHeight){$this->rowHeight = $rowHeight;}/*** @return array* [*    A1:K7 => '宋体'* ]*/public function setFont (array $font){$this->font = array_change_key_case($font, CASE_UPPER);}/*** @return array* @2020/3/22 10:33* [*    A1:K7 => true* ]*/public function setBold (array $bold){$this->bold = array_change_key_case($bold, CASE_UPPER);}/*** @return array* @2020/3/22 10:33* [*    A1:K7 => F0FF0F* ]*/public function setBackground (array $background){$this->background = array_change_key_case($background, CASE_UPPER);}/*** @return array* [*    A1:K7* ]*/public function setMergeCells (array $mergeCells){$this->mergeCells = array_change_key_case($mergeCells, CASE_UPPER);}/*** @return array* [*    A1:K7 => 14* ]*/public function setFontSize (array $fontSize){$this->fontSize = array_change_key_case($fontSize, CASE_UPPER);}/*** @return array* [*    A1:K7 => #000000* ]*/public function setBorders (array $borders){$this->borders = array_change_key_case($borders, CASE_UPPER);}
}

3、调用方法导出文件（UserController .php)

<?php
namespace App\Http\Controllers\Admin;
use Maatwebsite\Excel\Facades\Excel;
use App\Exports\UserExport;
use App\Models\User as userModel;
class UserController extends Controller
{/*** 用户列表导出* @param Request $request*/public function user_export(Request $request){//设置表头$row = [["id"=>'ID',"nickname"=>'用户昵称',"gender_text"=>'性别',"mobile"=>'手机号',"addtime"=>'创建时间  ']];//数据$list=[0=>["id"=>'1',"nickname"=>'张三',"gender_text"=>'男',"mobile"=>'18812345678',"addtime"=>'2019-11-21  '],2=>["id"=>'2',"nickname"=>'李四',"gender_text"=>'女',"mobile"=>'18812349999',"addtime"=>'2019-11-21  ']];//执行导出
$data = $list;//要导入的数据$header = $row;//导出表头$excel = new export($data, $header,'导出sheetName');$excel->setColumnWidth(['B' => 40, 'C' => 40]);$excel->setRowHeight([1 => 40, 2 => 50]);$excel->setFont(['A1:Z1265' => '宋体']);$excel->setFontSize(['A1:I1' => 14,'A2:Z1265' => 10]);$excel->setBold(['A1:Z2' => true]);$excel->setBackground(['A1:A1' => '808080','C1:C1' => '708080']);$excel->setMergeCells(['A1:I1']);$excel->setBorders(['A2:D5' => '#000000']);return Excel::download($excel, '导出文件.xlsx');

参考了网上搜罗来的源码加上实际开发中用的sheetName设置、合并单元格、设置边框、设置字体等，网上留存，以备后用
