The HTTP clients CurlClient and StreamClient are invoked with a ResponseFactoryInterface instance
as the first parameter, followed by optional HTTPOptions and PSR-3 LoggerInterface instances.
You can then send a request via the implemented PSR-18 method ClientInterface::sendRequest(),
using a PSR-7 RequestInterface and expect a PSR-7 ResponseInterface.
$options = new HTTPOptions; $options->ca_info = '/path/to/cacert.pem'; $options->user_agent = 'my cool user agent 1.0'; $options->dns_over_https = 'https://cloudflare-dns.com/dns-query'; $httpClient = new CurlClient($responseFactory, $options, $logger); $request = $requestFactory->createRequest('GET', 'https://www.example.com?foo=bar'); $httpClient->sendRequest($request);
The CurlMultiClient client implements asynchronous multi requests ("rolling-curl").
It needs a MultiResponseHandlerInterface that parses the incoming responses, the callback may return a failed request to the stack:
$handler = new class () implements MultiResponseHandlerInterface{ public function handleResponse( ResponseInterface $response, // the incoming response RequestInterface $request, // the corresponding request int $id, // the request id array|null $curl_info, // the curl_getinfo() result for this request ):RequestInterface|null{ if($response->getStatusCode() !== 200){ // return the failed request back to the stack return $request; } try{ $body = $response->getBody(); // the response body is empty for some reason, we pretend that's fine and exit if($body->getSize() === 0){ return null; } // parse the response body, store the result etc. $data = $body->getContents(); // save data to file, database or whatever... // ... } catch(Throwable){ // something went wrong, return the request to the stack for another try return $request; } // everything ok, nothing to return return null; } };
You can then invoke the multi request client - the MultiResponseHandlerInterface and ResponseFactoryInterface are mandatory,
HTTPOptions and LoggerInterface are optional:
$options = new HTTPOptions; $options->ca_info = '/path/to/cacert.pem'; $options->user_agent = 'my cool user agent 1.0'; $options->sleep = 750000; // microseconds, see usleep() $options->window_size = 5; $options->retries = 1; $multiClient = new CurlMultiClient($handler, $responseFactory, $options, $logger); // create and add the requests foreach(['..', '...', '....'] as $item){ $multiClient->addRequest($factory->createRequest('GET', $endpoint.'/'.$item)); } // process the queue $multiClient->process();
The URLExtractor wraps a PSR-18 ClientInterface to extract and follow shortened URLs to their original location.
$options = new HTTPOptions; $options->user_agent = 'my cool user agent 1.0'; $options->ssl_verifypeer = false; $options->curl_options = [ CURLOPT_FOLLOWLOCATION => false, CURLOPT_MAXREDIRS => 25, ]; $httpClient = new CurlClient($responseFactory, $options, $logger); $urlExtractor = new URLExtractor($httpClient, $responseFactory); $request = $factory->createRequest('GET', 'https://t.co/ZSS6nVOcVp'); $urlExtractor->sendRequest($request); // -> response from the final location // you can retrieve an array with all followed locations afterwards $responses = $this->http->getResponses(); // -> ResponseInterface[] // if you just want the URL of the final location, you can use the extract method: $url = $this->http->extract('https://t.co/ZSS6nVOcVp'); // -> https://api.guildwars2.com/v2/build
The LoggingClient wraps a ClientInterface and outputs the HTTP messages in a readable way through a LoggerInterface (do NOT use in production!).
$loggingClient = new LoggingClient($httpClient, $logger); $loggingClient->sendRequest($request); // -> log to output given via logger
The API documentation can be auto generated with phpDocumentor. There is an online version available via the gh-pages branch that is automatically deployed on each push to main.
Locally created docs will appear in the directory .build/phpdocs/. If you'd like to create local docs, please follow these steps:
- download phpDocumentor v3+ as .phar archive
- run it in the repository root directory:
- on Windows
c:\path\to\php.exe c:\path\to\phpDocumentor.phar --config=phpdoc.xml - on Linux just
php /path/to/phpDocumentor.phar --config=phpdoc.xml
- on Windows
- open index.html in a browser
- profit!
Use at your own risk!
