# Modèles de paramètres d'en-tête { #header-parameter-models }

Si vous avez un groupe de **paramètres d'en-tête** liés, vous pouvez créer un **modèle Pydantic** pour les déclarer.

Cela vous permet de **réutiliser le modèle** à **plusieurs endroits** et aussi de déclarer des validations et des métadonnées pour tous les paramètres en une seule fois. 😎

/// note | Remarque

Cela est pris en charge depuis la version `0.115.0` de FastAPI. 🤓

OkHttp Brotli Implementation
============================

This module is an implementation of [Brotli][1] compression.
It enables Brotli support in addition to tranparent Gzip support,
provided Accept-Encoding is not set previously.  Modern web servers
must choose to return Brotli responses.  n.b. It is not used for
sending requests.

```java
OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(BrotliInterceptor.INSTANCE)
  .build();

OkHttp DNS over HTTPS Implementation
====================================

This module is an implementation of [DNS over HTTPS][1] using OkHttp.

### Download

```kotlin
testImplementation("com.squareup.okhttp3:okhttp-dnsoverhttps:5.3.0")
```

### Usage

```
  val appCache = Cache(File("cacheDir", "okhttpcache"), 10 * 1024 * 1024)
  val bootstrapClient = OkHttpClient.Builder().cache(appCache).build()

MockWebServer for JUnit 5
=========================

This module integrates mockwebserver3.MockWebServer with JUnit 5.

To use, first add this library as a test dependency:

```
testImplementation("com.squareup.okhttp3:mockwebserver3-junit5:5.3.0")
```

Annotate fields in test classes with `@StartStop`. The server will be started and shut down
automatically.

```
class MyTest {

  @StartStop

plugins {
    `java-library`
    groovy

    id("gradlebuild.ci-reporting")
    id("gradlebuild.code-quality")
    id("gradlebuild.module-jar")
    id("gradlebuild.repositories")
    id("gradlebuild.reproducible-archives")
    id("gradlebuild.private-javadoc")
}

description = "A plugin that sets up a Java code that is shared between build-logic and runtime"

java {
    sourceCompatibility = JavaVersion.VERSION_1_8

OkHttp Zstandard (zstd) Integration
===================================

This module enables [Zstandard (zstd)][1] response compression in addition to Gzip, as long as
the `Accept-Encoding` header is not otherwise set. Web servers must be configured to return zstd
responses.

Note that zstd is not used for sending requests.

```java
OkHttpClient client = new OkHttpClient.Builder()
  .addInterceptor(CompressionInterceptor(Zstd, Gzip))
  .build();
