chillerlan/php-httpinterface

A PSR-7/PSR-17/PSR-18 HTTP message/client implementation.

Documentation

An API documentation created with phpDocumentor can be found at https://chillerlan.github.io/php-httpinterface/ (WIP).

Requirements

• PHP 8.4+
  • ext-curl
  • from dependencies:
    • ext-fileinfo
    • ext-intl
    • ext-json
    • ext-mbstring
    • ext-simplexml
    • ext-zlib

Installation with composer

Terminal

composer require chillerlan/php-httpinterface

composer.json

{
"require": {
"php": "^8.4",
"chillerlan/php-httpinterface": "dev-main#<commit_hash>"
}
}

Note: replace dev-main with a version constraint, e.g. ^7.0 - see releases for valid versions.

Profit!

Quickstart

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.

CurlClient, StreamClient

$options = newHTTPOptions;
$options->user_agent = 'my cool user agent 1.0';
$options->ca_info = '/path/to/cacert.pem';
$options->dns_over_https = 'https://cloudflare-dns.com/dns-query';
$options->curl_check_OCSP = true;
$options->curl_check_doh_OCSP = true;
$httpClient = newCurlClient($responseFactory, $options, $logger);
$request = $requestFactory->createRequest('GET', 'https://www.example.com?foo=bar');
$httpClient->sendRequest($request);

CurlMultiClient

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:

$handler = newclass () implements MultiResponseHandlerInterface{
publicfunctionhandleResponse(
ResponseInterface$response, // the incoming responseRequestInterface$request, // the corresponding requestint$id, // the request idarray|null$curl_info, // the curl_getinfo() result for this request
):RequestInterface|null{
if($response->getStatusCode() !== 200){
// return the failed request back to the stackreturn$request;
}
try{
$body = $response->getBody();
// the response body is empty for some reason, we pretend that's fine and exitif($body->getSize() === 0){
returnnull;
}
// parse the response body, store the result etc.$data = $body->getContents();
// save data to file, database or whatever...// ...
}
catch(Throwable){
// something went wrong, return the request to the stack for another tryreturn$request;
}
// everything ok, nothing to returnreturnnull;
}
};

You can then invoke the multi request client - the MultiResponseHandlerInterface and ResponseFactoryInterface are mandatory, HTTPOptions and LoggerInterface are optional:

$options = newHTTPOptions;
$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;
$multiClient = newCurlMultiClient($handler, $responseFactory, $options, $logger);
// create and add the requestsforeach(['..', '...', '....'] as$item){
$multiClient->addRequest($factory->createRequest('GET', $endpoint.'/'.$item));
}
// process the queue$multiClient->process();

Auto generated API documentation

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
• open index.html in a browser
• profit!
