### Documentation interactive de l'API

Rendez-vous sur <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>.

    * FastAPI provides more features on top of Starlette. Features that you almost always need when building APIs, like data validation and serialization. And by using it, you get automatic documentation for free (the automatic documentation doesn't even add overhead to running applications, it is generated on startup).

 * provides those capabilities, such as {@link Graph}, {@link ValueGraph}, or {@link Network}.
 *
 * <h3>Additional documentation</h3>
 *
 * <p>See the Guava User Guide for the {@code common.graph} package (<a
 * href="https://github.com/google/guava/wiki/GraphsExplained">"Graphs Explained"</a>) for
 * additional documentation, including <a

{* ../../docs_src/path_operation_configuration/tutorial002_py310.py hl[15,20,25] *}

They will be added to the OpenAPI schema and used by the automatic documentation interfaces:

## About security, APIs, and docs { #about-security-apis-and-docs }

Hiding your documentation user interfaces in production *shouldn't* be the way to protect your API.

That doesn't add any extra security to your API, the *path operations* will still be available where they are.

If there's a security flaw in your code, it will still exist.

Even if they are in different modules (Python files).

///

## Exclude from OpenAPI { #exclude-from-openapi }

To exclude a *path operation* from the generated OpenAPI schema (and thus, from the automatic documentation systems), use the parameter `include_in_schema` and set it to `False`:

{* ../../docs_src/path_operation_advanced_configuration/tutorial003.py hl[6] *}

        String title = DocumentUtil.getValue(document, fessConfig.getIndexFieldTitle(), String.class);
        if (StringUtil.isBlank(title)) {
            title = DocumentUtil.getValue(document, fessConfig.getIndexFieldFilename(), String.class);
            if (StringUtil.isBlank(title)) {
                title = DocumentUtil.getValue(document, fessConfig.getIndexFieldUrl(), String.class);
            }
