To log a request, you'll need to push Loguzz\Middleware\LogMiddleware to Guzzle's handler.

• $logger is the implementation of Psr\Log\LoggerInterface.
• $options is an array to change the default behaviour of LogMiddleware.
• 'logger' is the internal name of the middleware for Guzzle. It can be any name.

Options

• length - int. Minimum 10. To set the length of when formatting request with \Loguzz\Formatter\RequestCurlFormatter.
• log_request - bool. To enable or disable request logging.
• log_response - bool. To enable or disable response logging.
• success_only - bool. Only log successful responses. If the server could be reached, it's a success.
• exception_only - bool Only log exceptions. Logs when an exception is thrown by Guzzle for connection/timeout related exceptions.
• log_level - string. Any valid log level.
• request_formatter - instance of \Loguzz\Formatter\AbstractRequestFormatter. Available
  • \Loguzz\Formatter\RequestArrayFormatter
  • \Loguzz\Formatter\RequestCurlFormatter
  • \Loguzz\Formatter\RequestJsonFormatter
• response_formatter - instance of \Loguzz\Formatter\AbstractResponseFormatter
  • \Loguzz\Formatter\ResponseArrayFormatter
  • \Loguzz\Formatter\ResponseJsonFormatter
• exception_formatter - instance of \Loguzz\Formatter\AbstractResponseFormatter
  • \Loguzz\Formatter\ExceptionArrayFormatter
  • \Loguzz\Formatter\ExceptionJsonFormatter
• tag - string. Empty by default. When non-empty string, it'll log the formatted data under this tag. Tag can be used to search for specific type of request/response in your log file or your storage.
• force_json - bool. true by default. It is only applicable when tag is non-empty string. If enabled, it will then log data as json string, otherwise it'll log as an array. If set to false, the code may break due to the type-hint in psr/log interface. If your logger interface supports array, it will work.
• separate - bool. It is only applicable when tag is non-empty string. If enabled, it will then log data in {tag}.request, {tag}.success, {tag}.failure for request logging, successful response and error response.

Request Formatter

Response Formatter

To create a new response formatter you need to extend the \Loguzz\Formatter\AbstractResponseFormatter class.

Exception Formatter

To create a new exception formatter you need to extend the \Loguzz\Formatter\AbstractExceptionFormatter class.

Manual Request formatting

Implementations of \Loguzz\Formatter\AbstractRequestFormatter::format accept parameters as

• \Psr\Http\Message\RequestInterface $request
• array $options = []

Available request formatters parse data from $request and cookies from the $options. The values in $options['cookies'] must be an implementation of \GuzzleHttp\Cookie\CookieJarInterface. To parse cookies, the request URL must contain the domain.

Manual Response formatting

Implementations of \Loguzz\Formatter\AbstractResponseFormatter::format accept parameters as

• \Psr\Http\Message\RequestInterface $request
• \Psr\Http\Message\ResponseInterface $response
• array $options = []

Available response formatters parse data from $response and cookies from the set-cookie header. To parse cookies, the request URL must contain the domain.

The set-cookie headers will not be available in the headers for available response formatters.
