Can';t下载带有PHPSReadSheet的excel文件
我在PHP中使用angular 6,我想使用PHPSReadSheet下载一个excel文件 当我使用默认代码时Can';t下载带有PHPSReadSheet的excel文件,php,angular,phpexcel,phpspreadsheet,Php,Angular,Phpexcel,Phpspreadsheet,我在PHP中使用angular 6,我想使用PHPSReadSheet下载一个excel文件 当我使用默认代码时 $writer = new Xlsx($spreadsheet); $writer->save('hello world.xlsx'); 该文件在不下载的情况下生成到php文件夹中,工作正常。现在我想下载它并选择保存它的位置 我使用在文档中找到的代码 // redirect output to client browser header('Content-Type: appl
$writer = new Xlsx($spreadsheet);
$writer->save('hello world.xlsx');
该文件在不下载的情况下生成到php文件夹中,工作正常。现在我想下载它并选择保存它的位置
我使用在文档中找到的代码
// redirect output to client browser
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="myfile.xlsx"');
header('Cache-Control: max-age=0');
$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save('php://output');
但该文件未下载,我在浏览器中看到:
在我的PHP文件的开头,我有
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
我在安格尔的服务是:
export_excel(localUserid, date, projectid) {
return this.http.post(this.apiUrl, {localUserid, date, projectid},
{
headers : {
'Content-Type' : 'application/x-www-form-urlencoded; charset=UTF-8'
}
})
}
我将一些值传递给PHP。
我试着改变角度的标题,但没有任何效果。
有人知道怎么解决吗?
谢谢。在尝试了许多不同的解决方案后,我找到了使用Angular 6和phpsReadSheet下载excel文件的正确方法 首先,在PHP中,我必须将文件保存在本地:
$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
$file_name = 'D:\wamp64\www\angular6-app\client\download_excel\hello_world.xlsx'; //it depends where you want to save the excel
$writer->save($file_name);
if(file_exists($file_name)){
echo json_encode(array('error'=>false, 'export_path'=>'download_excel/' . 'hello_world.xlsx')); //my angular project is at D:\wamp64\www\angular6-app\client\
}
然后,我更改了我的excel.service.ts:
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http'
interface excel {
error: any,
export_path: any
}
@Injectable({
providedIn: 'root'
})
export class ExcelService {
apiUrl = "http://localhost/angular6-app/api/exportexcel.php";
constructor(private http: HttpClient) { }
export_excel(localUserid, date, projectid) {
return this.http.post<excel>(this.apiUrl, {localUserid, date, projectid},
{
headers : {
'Content-Type' : 'application/x-www-form-urlencoded; charset=UTF-8'
}
})
}
}
现在,我已将excel下载到我的下载文件夹中。我已尝试过此代码,它工作正常。代码采用Symfony和javascript,如下所示: 我的数组是这样的: 我使用过PHPOffice库。所以我使用了这些类: //现在控制器的Symfony代码开始:
private function generateAlphabets($al) {
$char = "";
while ($al >= 0) {
$char = chr($al % 26 + 65) . $char;
$al = floor($al / 26) - 1;
}
return $char;
}
function generateExcel(){
$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$header=[];
$coloumn=[];
$k=0;
foreach ($reportData[0] as $key=> $value) {
$header[]=$this->generateAlphabets($k);
$coloumn[]=$key;
$k++;
}
foreach ($coloumn as $key=>$value) {
$cell = $header[$key].'1';
$sheet->setCellValue($cell, $value);
}
$htmlString = '<table>';
$htmlString.='<tr>';
foreach ($coloumn as $value) {
$htmlString.="<th>".$value."</th>";
}
$htmlString.='</tr>';
foreach ($reportData as $index=>$array) {
$htmlString.='<tr>';
foreach ($array as $key => $value) {
$htmlString.="<td>".$array[$key]."</td>";
}
$htmlString.='</tr>';
}
$htmlString .= '</table>';
$internalErrors = libxml_use_internal_errors(true);
$reader = new \PhpOffice\PhpSpreadsheet\Reader\Html();
$spreadsheet = $reader->loadFromString($htmlString);
$writer = new Xlsx($spreadsheet);
$fileName="Excel_List_".(time()).".xlsx";
$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
$file_name = $fileName; //it depends where you want to save the excel
$writer->save($file_name);
chmod($file_name, 0777);
if(file_exists($file_name)){
return new JsonResponse(['error'=>false, 'export_path'=>'/','file'=>$fileName]);
}
}
public function removeExcel(Request $request){
$file = !empty($request->get('file'))?json_decode($request->get('file'),true):[];
$status=false;
if(!empty($file)){
if(file_exists($file)){
unlink($file);
$status=true;
}
}
return new JsonResponse(['success'=>$status]);
}
欢迎来到SO!即使你的答案是正确的,也试着对你的回答稍加评论,主要是在几乎所有的东西都是代码的时候。好的。我会牢记在心,并在未来的回答中给出更多细节。
