Loggable HTTP Client

Extended logging for the Symfony HTTP Client allowing especially to log the content of the request and response.

Adds events to PSR-3 logger interface:

• 'Response content:' (level: info) - response body content received; in context is available (details in Usage):
  • request (\Liborm85\LoggableHttpClient\Context\RequestContextInterface)
  • response (\Liborm85\LoggableHttpClient\Context\ResponseContextInterface)
  • info (\Liborm85\LoggableHttpClient\Context\InfoContextInterface)
• 'Response content (canceled):' (level: info) - same as above, only for canceled request (not all data may be available)

Adds additional information to getInfo() method:

• request_json (mixed) - json option from request $options (if is provided)
• request_body (\Liborm85\LoggableHttpClient\Body\BodyInterface) - body option from request $options transformed to object (if is provided)
• response_time (float) - the time when the response was received

Usage

<?php

$httpClient = \Symfony\Component\HttpClient\HttpClient::create(); // optional
$loggableHttpClient = new \Liborm85\LoggableHttpClient\LoggableHttpClient($httpClient);
$loggableHttpClient->setLogger(new \MyLogger());

$response = $loggableHttpClient->request('GET', 'https://example.com');


class MyLogger extends \Psr\Log\AbstractLogger
{

    public function log($level, $message, array $context = []): void
    {
        if (isset($context['request']) && ($context['request'] instanceof \Liborm85\LoggableHttpClient\Context\RequestContextInterface)) {
            $context['request']->getContent(); // request content body as string
            (string)$context['request']; // is Stringable, request content body as string
            $context['request']->toStream(); // request content body as PHP stream
            $context['request']->getHeadersAsString(); // request headers as string
            $context['request']->getHeaders(); // request headers as array (string[][])
            $context['request']->getRequestTime(); // request time as DateTimeInterface
            $context['request']->getRequestMethod(); // request HTTP method
            $context['request']->getUrl(); // full request URL
        }

        if (isset($context['response']) && ($context['response'] instanceof \Liborm85\LoggableHttpClient\Context\ResponseContextInterface)) {
            $context['response']->getContent(); // response content body as string
            (string)$context['response']; // is Stringable, response content body as string
            $context['response']->toStream(); // response content body as PHP stream
            $context['response']->getHeadersAsString(); // response headers as string
            $context['response']->getHeaders(); // response headers as array (string[][])
            $context['response']->getResponseTime(); // response time as DateTimeInterface
        }

        if (isset($context['info']) && ($context['info'] instanceof \Liborm85\LoggableHttpClient\Context\InfoContextInterface)) {
            $context['info']->getInfo(); // return all available information
            $context['info']->getInfo('url'); // return one information for provided type
        }
    }
