# Concepts de déploiement { #deployments-concepts }

Lorsque vous déployez une application **FastAPI**, ou en fait n'importe quel type de web API, il existe plusieurs concepts qui vous importent probablement, et en les utilisant vous pouvez trouver la manière la **plus appropriée** de **déployer votre application**.

Parmi les concepts importants, on trouve :

* Sécurité - HTTPS
* Exécuter au démarrage
* Redémarrages

     * Sets up the command list, working directory, and environment variables,
     * then starts the Python process and waits for completion.
     *
     * @throws JobProcessingException if the Python script execution fails
     */
    protected void executePython() {
        final List<String> cmdList = new ArrayList<>();
        final ServletContext servletContext = ComponentUtil.getComponent(ServletContext.class);

            // Single zero should not be compressed
            assertEquals("2001:db8:1:0:2:3:4:5", method.invoke(null, "2001:0db8:1:0:2:3:4:5"));
        } catch (Exception e) {
            // If reflection fails, skip this test
        }
    }

    @Test
    public void testIsIPv6Address() {
        // IPv6 addresses
        assertTrue(IpAddressUtil.isIPv6Address("::1"));

	MaximumFileSize int64

	// FileNameFunc specifies the name a new file will take.
	// FileNameFunc must ensure collisions in filenames do not occur.
	// Do not rely on timestamps to be unique, high throughput writes
	// may fall on the same timestamp.
	// Eg.
	// 	2020-03-28_15-00-945-<random-hash>.log
	// When FileNameFunc is not specified, DefaultFilenameFunc will be used.
	FileNameFunc func() string

pkg net/mail, func ReadMessage(io.Reader) (*Message, error)
pkg net/mail, method (*Address) String() string
pkg net/mail, method (Header) AddressList(string) ([]*Address, error)
pkg net/mail, method (Header) Date() (time.Time, error)
pkg net/mail, method (Header) Get(string) string
pkg net/mail, type Address struct
pkg net/mail, type Address struct, Address string

     * @param failureReason the reason for failure ("no_results" or "no_relevant_results")
     * @param history the conversation history
     * @return a new query string, or the userMessage if regeneration fails
     */
    String regenerateQuery(String userMessage, String failedQuery, String failureReason, List<LlmMessage> history);

    /**
     * Generates an answer using document content (streaming version for enhanced flow).

 *   <li>comparing each pair of objects from different equality groups returns false
 *   <li>the hash codes of any two equal objects are equal

 *
 * <p>When a test fails, the error message labels the objects involved in the failed comparison as
 * follows:

 * <ul>
 *   <li>"{@code [group }<i>i</i>{@code , item }<i>j</i>{@code ]}" refers to the

Mais ensuite, les attaquants essaient avec le nom d'utilisateur `stanleyjobsox` et le mot de passe `love123`.

Et le code de votre application fait quelque chose comme :

```Python
if "stanleyjobsox" == "stanleyjobson" and "love123" == "swordfish":
    ...
```

# CORS (Partage des ressources entre origines) { #cors-cross-origin-resource-sharing }

[CORS ou « Cross-Origin Resource Sharing »](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) fait référence aux situations où un frontend exécuté dans un navigateur contient du code JavaScript qui communique avec un backend, et où le backend se trouve dans une « origine » différente de celle du frontend.

Graças ao [Starlette](https://www.starlette.dev/testclient/), testar aplicações **FastAPI** é fácil e agradável.

Ele é baseado no [HTTPX](https://www.python-httpx.org), que por sua vez é projetado com base em Requests, por isso é muito familiar e intuitivo.

Com ele, você pode usar o [pytest](https://docs.pytest.org/) diretamente com **FastAPI**.
