我试图在laravel中使用ajax方法下载excel文件。 控制器功能:
$myFile = Excel::create($name, function ($excel) use ($export) {
$excel->sheet('Data', function ($sheet) use ($export) {
$sheet->fromArray($export);
$sheet->cells('A1:N1', function ($cells) {
$cells->setBackground('#dbdbdb');
$cells->setFontColor('#000000');
$cells->setFontWeight('bold');
$cells->setFont(array(
'family' => 'Calibri',
'size' => '9',
));
});
$sheet->setStyle(array(
'font' => array(
'name' => 'Calibri',
'size' => 9,
),
));
});
});
$myFile = $myFile->string('xlsx');
$response = array(
'name' => $name,
'file' => "data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;base64," . base64_encode($myFile),
);
return response()->json($response);
Ajax功能:
$(document).on('click', '.ExportJobs', function() {
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
var ids = [];
$(".InvoiceCheckBox:checked").each(function(e) {
ids.push(this.value);
});
data = {
"ids": ids,
};
$.ajax({
method: "POST",
url: "/exportNew",
data: data,
success: function(response) {
var a = document.createElement("a");
a.href = response.file;
a.download = response.name;
document.body.appendChild(a);
a.click();
a.remove();
}
});
});
但是,如果我将字符串值从xlsx
更改为csv
,则使用上述控制器方法不会返回excel格式的文件,然后csv
格式化文件将被下载。
我们如何下载excel格式的文件?有任何建议,拜托!

我知道这已经很晚了,但要为像我这样遇到同样问题的人发帖
我还需要通过使用ajax发布调用从Maatwebsite excel库中下载excel。
添加了一个按钮来触发ajax调用以下载excel文件
<button onclick="downloadExcel()" id="btn-download-payroll" class="btn btn-dark-success btn-md" style="transform: translateY(50%); top: 50%; font-size: 13px;"><i aria-hidden="true" class="fa fa-cog mr-10"></i>
Download
</button>
使用以下js代码发布ajax请求
function downloadExcel() {
var salaryMonth = $("#dp-salary-month").datepicker("getDate");
var department = $("#cbox-department");
var month = new Date(salaryMonth).getMonth() + 1;
var year = new Date(salaryMonth).getFullYear();
$.ajax({
xhrFields: {
responseType: 'blob',
},
type: 'POST',
url: '/downloadPayroll',
data: {
salaryMonth: month,
salaryYear: year,
is_employee_salary: 1,
department: department.val()
},
success: function(result, status, xhr) {
var disposition = xhr.getResponseHeader('content-disposition');
var matches = /"([^"]*)"/.exec(disposition);
var filename = (matches != null && matches[1] ? matches[1] : 'salary.xlsx');
// The actual download
var blob = new Blob([result], {
type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
});
var link = document.createElement('a');
link.href = window.URL.createObjectURL(blob);
link.download = filename;
document.body.appendChild(link);
link.click();
document.body.removeChild(link);
}
});
}
在 routes / web.php 文件中为我的控制器设置路径
Route::post('/downloadPayroll', 'Payroll\\Process\\PayrollController@downloadPayroll');
这里,我使用 maatwebsite / excel 库通过 FromQuery 方法生成excel文件,但是由于库更新,Excel :: create已由<: strong>“ maatwebsite / excel”:“ ^ 3.1” 在我的案例中,我使用了下载方法,这里是我的HelperClass根据我的要求生成记录
PayrollHelper.php
namespace App\Http\Helpers;
use App\PayrollEmployee;
use Maatwebsite\Excel\Concerns\FromQuery;
use Maatwebsite\Excel\Concerns\Exportable;
class PayrollHelper implements FromQuery
{
use Exportable;
public function forDepartment(int $department)
{
$this->department = $department;
return $this;
}
public function forMonth(string $month)
{
$this->month = $month;
return $this;
}
public function query()
{
// get the salary information for the given month and given department
return PayrollEmployee::query()->where(['salary_month' => $this->month,'department_id'=>$this->department]);
}
}
最终在我的控制器中
class PayrollController extends Controller
{
public function downloadPayroll(Request $request)
{
$file_name = '';
try {
$requestData = $request->all();
$salary_month = $requestData['salaryMonth'];
$salary_year = $requestData['salaryYear'];
$department = $requestData['department'];
$is_employee_salary = boolval($requestData['is_employee_salary']);
$month = Carbon::createFromDate($salary_year, $salary_month);
$month_start = Carbon::parse($month)->startOfMonth();
$formated_month = Carbon::parse($month)->format('F Y');
$file_name = 'Employee_salary_' . $formated_month . '.xlsx';
// to download directly need to return file
return Excel::download((new PayrollHelper)->forMonth($month_start)->forDepartment($department), $file_name, null, [\Maatwebsite\Excel\Excel::XLSX]);
} catch (exception $e) {
}
}
}
创建excel文件后,返回文件以ajax 响应为blob
就这样

我也遇到了完全相同的问题,但是对我来说,我的代码可以正常工作,但是下载文件的内容不可读,而且仍然经过编码。
如果您可以帮助我,那就好了...
这里是ajax调用:
$.ajax({
type:"post",
url: btnExportExcel.attr('data-url-export'),
responseType:'document',
data: {
projetsJSON: JSON.stringify(projets)
},
success:function(data,status,xhr) {
console.log("success")
var disposition = xhr.getResponseHeader('content-disposition');
var matches = /"([^"]*)"/.exec(disposition);
var filename = (matches != null && matches[1] ? matches[1] : 'salary.xlsx');
var blob = new Blob([data],{type:'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'});
var downloadUrl = URL.createObjectURL(blob);
var a = document.createElement("a");
a.href = downloadUrl;
a.download = filename
document.body.appendChild(a);
a.click();
},
error: function(jqXHR, textStatus,errorThrown) {
alert(errorThrown);
}
})
它很好用,并以json发送数据。 之后,我调用从控制器加载此功能的路由:
/**
* Fonction d'export Excel
* @return Excel
*/
public function exportExcel(Request $request) {
$projets = json_decode($request->projetsJSON);
return Excel::download(new ProjetsExport($projets),'projets'. date('Y-m-d') . '.xlsx');
}
在ProjetsExport
类的构造函数中,我将在数组中解码的数据传递给参数:
<?php
namespace App\Exports;
use App\Models\Projet;
use Maatwebsite\Excel\Concerns\FromArray;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\WithMapping;
class ProjetsExport implements FromArray, WithHeadings, WithMapping
{
protected $request;
public function __construct($request)
{
$this->request = $request;
}
/**
* @return array
*/
public function array():array
{
return $this->request;
}
/**
* Initialisation des headers des colonnes du fichier Excel.
*/
public function headings(): array
{
return ['Libellé','Date de création','Date de fin','Budget HT','Objectif','Etat','Type','Ouverture','Chef de projet','Famille'];
}
/**
* Formattage des données.
*/
public function map($row): array
{
return [
$row->libelle,
(new \DateTime($row->dt_creation))->format('d/m/Y'),
(new \DateTime($row->dt_fin))->format('d/m/Y'),
$row->budget_ht,
$row->obj_collect,
$row->type_proj,
$row->ouverture,
$row->chef_proj,
$row->famille
];
}
}
然后,如果上面显示的ajax调用成功,那么我将创建一个blob对象,然后下载该对象,并且得到了此类文档。
