octane: Response doesn't support stream-based output

• Octane Version: 0.1.0
• Laravel Version: 8.36.1
• PHP Version: 8.0.3
• Database Driver & Version:

Description:

Most of PHP’s output usages like echo, var_dump output its content to buffer. In Swoole’s case the result will print on console instead of web.

It seems this partial code in SwooleClient.php refers from here https://github.com/laravel/octane/blob/08537a7ed6d2c463f76278081ac7af9a6dd1dead/src/Swoole/SwooleClient.php#L153-L178 because the output property doesn’t exist in symfony’s response object. The output property is set from here in swooletw/laravel-swoole.

Symfony\Component\HttpFoundation\StreamedResponse doesn’t support getContent and setContent for setting output content, so I fetch buffer output and set the result to response’s output property manually.

If Octane is going to support stream output, it needs to use ob_ functions to catch stream content as well.

Many thanks to the official team for integrating Swoole into Laravel!

Steps To Reproduce:

echo 'hello world';

var_dump('Swoole is awesome');

response()->streamDownload(function () {
    echo file_get_contents("https://github.com/laravel/laravel/blob/8.x/README.md");
    }, 'laravel-readme.md');
});
