HTTP Client File Download
Hello,
I am using HTTP Client to try and download file from external server via api. I am using get methong with some basicAuth to connect and fetch the file that I want.
In the browser when I lunch the URL eveything is fine, the file starts to download but I can't seem to get it work inside the application.
I am getting errors like:
Symfony \ Component \ HttpFoundation \ File \ Exception \ FileNotFoundException
or
Argument #1 must not contain any null bytes (when I do dump(strlen($file)) there seems to be data)
How can I make this work? Best Regards!

$file = Http::withBasicAuth(username, password)->withHeaders([
'accept' => 'application/octet-stream',
])->get('http://mydomain.com/Download?docId='.$id);
return response()->download($file);
There is not much really to the code

@iKyzu did you try just saving it to disk? As a test
$response = Http::withBasicAuth(username, password)->withHeaders([
'accept' => 'application/octet-stream',
])->get('http://mydomain.com/Download?docId='.$id);
Storage::putFile('downloads', $response->body());
Or try a streamed download
return response()->streamDownload(function () {
$response = Http::withBasicAuth(username, password)->withHeaders([
'accept' => 'application/octet-stream',
])->get('http://mydomain.com/Download?docId='.$id);
echo $response->body();
}, 'filename.pdf'); // replace with actual name

When I try to save it in a disk I am getting: Symfony \ Component \ HttpFoundation \ File \ Exception \ FileNotFoundException
Stream download - download a file but it's empty/damaged (0 bytes)

@iKyzu seems to not be possible then unless you are just getting an error. Did you check? https://laravel.com/docs/9.x/http-client#error-handling

@Sinnbeck I am getting 200 status code
Level 102
@iKyzu are you able to download any other file using this technique? From a site without auth
Level 1
@Sinnbeck yes I am able to download other file using this technique.
I see I need to find what's wrong with the place I am trying to get the file from.
Level 1
@Sinnbeck I dont undestand I even try to just put in the browser link:
http://user:password@localhost:8080/Download?fileId=4ca63b87-e340-443e-aeef-6c7e2fb57aea
With of course changing the user and password and it's working inside my browser. Right away from clicking enter the file is starting to download even with the name itself.
Level 1
@Sinnbeck I found a way to work:
$tempFile = tempnam(sys_get_temp_dir(), $fileName);
copy('http://localhost/Download?fileId='.$id, $tempFile);
return response()->download($tempFile, $fileName);

when it says mydomain.com, is it another webserver? You are not trying to load from this same site (as a test)?
Level 1
@Snapey With mydomain.com I mean another webserver since the file should be downloaded from the server.

I had issues recently download a .pdf blob from my report server and this is what solved for me. Just a little context, my report server (.Net Core app) is another docker container running on the same docker network as my Laravel app container and the report server is not exposed to the internet, the reason with I used the withoutVerifying() method.
...
$myUrl = 'url path to the file';
$report = ReportResource::find($id);
$tempFile = tempnam(sys_get_temp_dir(), $fNameTemp);
Http::withoutVerifying()->send('GET', $myUrl, ['sink' => $tempFile]);
return response()->download($tempFile, $report->name.'.'.$report->export_type);

With laravel 11, this worked for me
Storage::put("file.pdf", $response->body());
The filename can be generated dynamically though.
