如何使用 Mojolicious 上传多个文件？

Question

我是 Mojolicious 的新手，正在尝试学习它。 我正在尝试使用表单上传多个文件，但一次只上传一个文件。 有什么建议吗？

#!perl -w

use Mojolicious::Lite;
use Mojo::Upload;
use v5.14;

get '/' => 'page';
post '/' => sub {
   my $self = shift;
   my @files;
   for my $file ($self->req->upload('files')) {
     my $size = $file->size;
     my $name = $file->filename;

     push @files, "$name ($size)";
     $file->move_to("C:\\Program Files\\Apache Software Foundation\\Apache24\\htdocs\\ProcessingFolder\\".$name);
   }
   $self->render(text => "@files");
} => 'save';

app->start;

Answer 1

找到答案。 使用uploads()而不是upload()返回数组引用。

#!perl -w

use Mojolicious::Lite;
use Mojo::Upload;
use v5.14;

get '/' => 'page';
post '/' => sub {
   my $self = shift;
   my @files;
   for my $file (@{$self->req->uploads('files')}) {
     my $size = $file->size;
     my $name = $file->filename;

     push @files, "$name ($size)";
     $file->move_to("C:\\Program Files\\Apache Software Foundation\\Apache24\\htdocs\\ProcessingFolder\\".$name);
   }
   $self->render(text => "@files");
} => 'save';

app->start;

Answer 2

我认为上面的答案中有一个小错误 - 变量 ProcessingFolder 已过时......

#!perl -w
# install Mojolicious by : sudo -s 'curl -L cpanmin.us | perl - Mojolicious'
# run by : perl mojo-file-upload.pl daemon -m production -l http://*:8083
# point your browser @: http://127.0.0.1/upload-files
#
use Mojolicious::Lite;
use Mojo::Upload;
use v5.14;

get '/' => 'upload-files-page';
get '/upload-files' => 'upload-files-page';
post '/upload-files' => sub {
   my $self = shift;
   my @files;
   for my $file (@{$self->req->uploads('files')}) {
     my $size = $file->size;
     my $name = $file->filename;

     push @files, "$name ($size)";
     $file->move_to("/tmp/".$name);
   }
   $self->render(text => "@files");
} => 'save';

app->start;
