Anonymize or truncate parts of json or xml payloads and request headers before logging with a guzzle middleware.
For data protection you might not want to log personal data, like names, addresses etc in your requests.

Usage

Example usage for Json Payloads:

... $formatter = new GuzzleMessageJsonAnonymizerFormatter( ['PersonalData'], $substitute = '*****', AbstractAnonymizerFormatter::DEBUG, ['Authorization' => '*****'] ); $loggerMiddleware = Middleware::log($logger, $formatter); $stack->push($loggerMiddleware); $config = [ ... 'handler' => $stack, ]; $client = new Client($config); 

This will log:

<<<<<<<< HTTP/1.1 200 OK Date: Thu, 18 Jun 2020 10:04:21 GMT Content-Type: application/json Authorization: ***** ... { ... "Payload": { "Foo": "Bar", ... "PersonalData": "*****" }, ... } 

Usage Symfony

Declare the Formatter service:

Freshcells\GuzzleMessageAnonymizerFormatter\GuzzleMessageXmlAnonymizerFormatter: arguments: $elements: - 'none:FirstName' - 'none:LastName' $attributes: - 'none:Customer[@Age]' $namespaces: none: 'http://namespace.de/middleware/payment/' $truncateElements VeryLongText: 200 

Override existing message formatter of a logger middleware:

csa_guzzle.logger.message_formatter: alias: 'Freshcells\GuzzleMessageAnonymizerFormatter\GuzzleMessageXMLAnonymizerFormatter' 

Or declare a dedicated anonymizer_logger middleware:

guzzle.middleware.anonymizer_logger: class: Closure factory: ['GuzzleHttp\Middleware', log] arguments: ['@monolog.logger', '@Freshcells\GuzzleMessageAnonymizerFormatter\GuzzleMessageXmlAnonymizerFormatter', 'info'] tags: - { name: csa_guzzle.middleware, alias: anonymizer_logger }
