HTTP Client Adapters

For GenerationTarget::Client, the generator emits typed API clients with one of three HTTP transport styles.

Overview

Adapter	Constructor Dependencies	Request Method	Good Choice For
`HttpClientAdapter::SymfonyHttpClient`	`Symfony\Contracts\HttpClient\HttpClientInterface`	`request()`	Symfony apps and lightweight clients
`HttpClientAdapter::Guzzle`	`GuzzleHttp\ClientInterface`	`request()` + `RequestOptions`	Existing Guzzle middleware stacks
`HttpClientAdapter::Psr18`	`Psr\Http\Client\ClientInterface`, request factory, stream factory	`sendRequest()`	Portable libraries and framework-neutral code

All adapters expose the same generated API signatures (*ApiClientInterface + *ApiClient).

Generated Files

generated/
|- Api/
|  |- PetsApiClientInterface.php
|  `- PetsApiClient.php
`- Model/
   |- Pet.php
   |- NewPet.php
   `- ...

Shared Runtime Behavior

path parameters are inserted without redundant concatenation fragments
nullable query params are omitted from the final request
request bodies use generated toArray() output
response payloads are mapped back via generated fromArray() methods
void operations still execute HTTP calls and skip response deserialization

Typical Configuration

use MaxBeckers\OpenApiGenerator\Config\GenerationTarget;
use MaxBeckers\OpenApiGenerator\Config\HttpClientAdapter;

$config->generationTarget = GenerationTarget::Client;
$config->httpClient = HttpClientAdapter::SymfonyHttpClient; // symfony|guzzle|psr18
$config->httpClientVersion = '7.0'; // optional, when adapter majors require different generated code

Leave $config->httpClientVersion as null if you do not need adapter-version-specific generation yet.
