一、前提
想要将excel内容入库，laravel有扩展可以使用,常用的扩展是maatwebsite/excel，安装步骤参考上一篇：laravel中安装Maatwebsite/excel扩展
二、使用
2.1、新建一个导入文件
php artisan make:import 文件名称 --model=Model地址
然后在里边编写你的导入逻辑
<?php
namespace App\Imports;
use App\Exceptions\ApiException;
use Illuminate\Support\Facades\DB;
use Maatwebsite\Excel\Concerns\ToArray;
use Maatwebsite\Excel\Concerns\WithChunkReading;
use Maatwebsite\Excel\Concerns\WithHeadingRow;
class QuesExport implements ToArray, WithChunkReading, WithHeadingRow
{
public function array(array $rows)
{
$data = [];
$now = date('Y-m-d H:i:s');
foreach ($rows as $row) {
$data[] = [
'id' => $row['id'],
'number' => 0,
'parent_id' => 0,
'type' => 1,
'question' => $row['ques'],
'standard_answer' => $row['answer'],
'ai_ques_id' => $row['aiid'],
'created_at' => $now
];
}
if (!$data) {
throw new ApiException('没有要导入的数据');
return false;
};
//全部导入
DB::select('TRUNCATE table questions_copy1');
DB::table('questions_copy1')->insert($data);
return true;
}
public function chunkSize(): int
{
return 500;
}
public function headingRow(): int
{
return 1;
}
/**
* @param Failure[] $failures
*/
public function onFailure(Failure ...$failures)
{
// Handle the failures how you'd like.
throw new ApiException('fhwaeurewsdf');
}
}
2.2、新建一个控制器和方法,调用导入文件
/**
* 导入excel，入库
*
* */
public function uploadQues(Request $request){
$file = $request->file('file');
// 保存上传文件
$path = public_path('uploads/admin/ques');
$this->mkdirs($path); // 已存在的路径不会再创建
$fileName = date('YmdHis') . '_' . uniqid() . '_' . '.' . strtolower($file->getClientOriginalExtension());
$file->move($path, $fileName);
// 读取文件并入库
Excel::import(new QuesExport(), $path . '/' . $fileName);
// 删除上传文件
unlink($path . '/' . $fileName);
return response()->json([
'status'=>1,
'msg'=>'',
]);
}
2.3、 新建一个页面，支持文件上传
我这里简单写了个页面，如下：
<!DOCTYPE html>
<html >
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Laravel</title>
<script src="/js/jquery-3.3.1.min.js?v=2021123999" type="text/javascript" charset="utf-8"></script>
<meta name="csrf-token" content="{{ csrf_token() }}">
</head>
<body>
<div class="flex-center position-ref full-height">
<div class="upload_box">
<input type="file" name="file" accept="file" id="auth-upload" onchange="uploadFile();"/>
<div class="reload_file flex-v flex-vc flex-hc">
<i class="icon icon_add"></i>
<p>文件</p>
</div>
</div>
</div>
<script>
function uploadFile(){
file = $("#auth-upload")[0].files[0];
// alert(file);
// alert(file.name);
// return;
file_name = file.name;
ext = file_name.slice(file_name.lastIndexOf(".")+1).toLowerCase();
imgMaxSize = 1024*1024*10;
if (ext != 'xlsx' ) {swal('文件格式不正确');return ;}
// if (file.size > imgMaxSize) {swal('文件大小超过10M'); return ;}
formData = new FormData();
// 自定义formData中的内容
formData.append('file', file);
formData.append('_token', '{{csrf_token()}}');
$.ajax({
type: 'POST',
url: "/upload",
data: formData,
cache: false,
processData: false,
contentType: false,
dataType:'json',
success: function (data) {
if (data.status){
alert('成功');
}else{
alert('失败');
}
}
});
}
</script>
</body>
</html>
