Download a file from command line in laravel artisan - php

Question

I am using laravel Artisan Commands to download a file from public folder .
Actually i want to download a zip file which i have successfully made in public folder.
I am able to download the file when I call the methods on button click.
But when I execute the command in console it does not work and also not throw any error.
public function downloadExportRawData() {
$a=public_path().'/temp/rawexport/rawexportproduct.zip';
$path='/temp/rawexport/rawexportproduct.zip';
if(file_exists('temp/rawexport/rawexportproduct.zip')){
return Response::download($a);
}else{
return "hello";
}
}
Tried this also...
public static function downloadZip($rand_folder, $zipname, $fileName) {
header('Content-Type: application/force-download');
header('Content-Disposition: attachment; filename="' . $fileName . '.zip"');
header('Content-Length: ' . filesize($zipname));
$handle = fopen($zipname, 'rb');
//exec("rm -r ".$temp);
while (!feof($handle)) {
echo fread($handle, 1048576);
ob_flush();
flush();
}
fclose($handle);
// exec("rm -r " . $rand_folder);
}
and the command is
php artisan product:export --from=http://localhost/valuable-app/dev-master/rest_app/public/ --productid=5b273b0e4bb5995b108b4576 --tokenexport=354c3ddb2bd45aa6e5c4f749749b0b58cbacef48
The main problem is that it is going through the function in controller but not downloading it.
And I tried to echo the response it prints code in zip form means a encoded form which have something related to my zip file means its printing the zip not downloading it.
I am using Artisan first time. Any idea how to download that file using using user-defined Artisan command.
I am trying this from last two weeks but not able to do anything.

Answer 1

How about this:
First identify the file which you want to download and then call
string shell_exec ( string $cmd )
you can use wget to get the file.
for example, in your command
$fileName = $this->argument('filename');
$file = url('storage/public/' . $fileName);
shell_exec("wget $file");
$this->info('downloading');

Answer 2

if you'r using the console, the http download will not work (you are not using a browser).
Instead you can move the file to your wished destination or something like that, but not download it via console

Answer 3

console will not handle http response as download (will not save it)
I think you should consider to add second argument in your console:
--destination=/home/user/downloads/filetosaveas.extension and in your code use curl to download
or more simple use core curl:
curl http://example.com --output my.file --silent

It would be nice if you actually went through the nicely done Writing Commands guide at the Laravel Docs site, here.
In a nutshell, there are mainly two ways to register artisan command. Be it that one is an alternative to the other.
(Like routes) specify your instructions within a closure.
(Like controllers) create a command class and specify your instructions.
The closure way
Inside my routes/console.php, I specify something like below:
Artisan::command('download:file', function () {
// your code goes here.
})->describe('Download a file.');
Now execute a help routine for your newly created command.
-> php artisan help download:file
Description:
Donwload a file.
Usage:
donwload:file
//...
The command way
Generate the command class using php artisan make:command EmailFileCommand. This command will create app/Console/Commands/EmailFileCommand.php. Update the file to specify what we want it to do.
// ...
class EmailFileCommand extends Command
{
/**
* The name and signature of the console command.
*
* #var string
*/
protected $signature = 'email:file';
/**
* The console command description.
*
* #var string
*/
protected $description = 'Email a file.';
/**
* Create a new command instance.
*
* #return void
*/
public function __construct()
{
parent::__construct();
}
/**
* Execute the console command.
*
* #return mixed
*/
public function handle()
{
// your code goes here.
}
}
Trigger commands via HTTP
Say you want to call the commands via an http request. In my routes/web.php file,
//...
use Artisan;
//...
Route::get('/download', function () {
Artisan::call('download:file');
});
Route::get('/email', function () {
Artisan::call('email:file');
});
//...
Now execute your http requests /download and /email.
To download a file, you can use Laravel's Filesystem.
//...
use Storage;
//...
Storage::download('file.jpg')

One can use the shell_exec() command to run a terminal command through PHP function or script. It will execute the command without opening the terminal window. the behaviour of command will be little bit different from the original command.
