php-guzzleHow to use Monolog with Guzzle in PHP?

Monolog is a logging library for PHP which can be used with Guzzle to log requests and responses.

use Monolog\Logger;
use Monolog\Handler\StreamHandler;

$logger = new Logger('guzzle');
$logger->pushHandler(new StreamHandler('/path/to/your.log', Logger::DEBUG));

$client = new GuzzleHttp\Client([
    'base_uri' => 'http://httpbin.org',
    'handler' => GuzzleHttp\HandlerStack::create(
        new GuzzleHttp\Handler\CurlHandler(),
        new GuzzleHttp\Handler\LoggingHandler($logger)
    )
]);

$response = $client->get('/get');

The output of the example code will be a log file containing the request and response information.

Code explanation

1. use Monolog\Logger; and use Monolog\Handler\StreamHandler; - These lines import the Monolog library and the StreamHandler class.

2. $logger = new Logger('guzzle'); - This line creates a new Logger instance with the name 'guzzle'.

3. $logger->pushHandler(new StreamHandler('/path/to/your.log', Logger::DEBUG)); - This line adds a StreamHandler to the Logger instance, which will write the log messages to the specified file.

4. new GuzzleHttp\Handler\LoggingHandler($logger) - This line creates a LoggingHandler instance which will use the Logger instance to log the requests and responses.

5. $client = new GuzzleHttp\Client([...]) - This line creates a new Guzzle client with the LoggingHandler added to the handler stack.

6. $response = $client->get('/get'); - This line sends a GET request to httpbin.org and stores the response in the $response variable.
