CI 4 Output Compression - [email protected] - 06-18-2021

Hi..

Anyone can help how to set output compression on CI4?

I read about content negotiation but no luck to set the output.

On CI 3 i just change to this line on config.php

$config['compress_output'] = TRUE;

Thanks..

Thanks, i am new on web programming. I have read that but still not sure how to make it works. I've tried this code on controller :

$negotiate = \Config\Services::negotiator();
$type = $negotiate->encoding(['gzip']);

But the output still not on gzip encoding.
I am using ajax call to controller and check the content encoding on firefox with inspect.

If I remember correctly there is a php.ini setting for it. Also you need to check your hosting provider
to see what types of encoding they allow. Check php.ini for mod_deflate.

Code:
# BEGIN GZIP

<ifmodule mod_deflate.c>

AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript

</ifmodule>

# END GZIP

This is for .htaccess GZip.

Thanks for replying,
The server support gzip. Client browser also. Before i was doing with setting config.php output compression = true on CI3, so i was hoping if there is a way to set that on CI4 so that i dont have to modify htaccess or php.ini
I was saving for last if there is no way to set through CI4.
I'm on process on learning how to compress just the ajax response data.

In your Controller you can call for negotiator service to set gzip encoding.

PHP Code:
service('negotiator')->encoding(['gzip']); 

In your public/.htaccess you may define other resources by file-extension to be gzip encoded by apache.

Code:
<IfModule mod_deflate.c>

 <FilesMatch "\.(js|css|html|htm|php|json|xml|jpg|jpeg|gif|raw)$">

 SetOutputFilter DEFLATE

 </FilesMatch>

</IfModule>

For apache gzip encoding to work: make sure you have this line uncommented in your apache/conf/httpd.conf

Code:
LoadModule deflate_module modules/mod_deflate.so

Let me know if it worked for you Smile

In my case i don't have to set this in controller. Just with the .htaccess and mod_deflate.so enable to make it work.
Thanks.
But still is there no other way to set compression without changing apache module?
I found a way to force gzip/compression without changing apache module but not sure if it's a good practice.
I edit Events.php file in config like this :

Code:
if(!ob_start("ob_gzhandler")){

 if (ini_get('zlib.output_compression'))

 {

 throw FrameworkException::forEnabledZlibOutputCompression();

 }

 while (ob_get_level() > 0)

 {

 ob_end_flush();

 }

 ob_start(function ($buffer) {

 return $buffer;

 });

 }
