**FastAPI** is based on **OpenAPI**.

That's what makes it possible to have multiple automatic interactive documentation interfaces, code generation, etc.

OpenAPI has a way to define multiple security "schemes".

By using them, you can take advantage of all these standard-based tools, including these interactive documentation systems.

The generated responses in the OpenAPI for this *path operation* will be:

```JSON hl_lines="3-12"
{
    "responses": {
        "404": {

    "jinja2 >=3.1.5",
    # For forms and file uploads
    "python-multipart >=0.0.18",
    # For Starlette's SessionMiddleware, not commonly used with FastAPI
    "itsdangerous >=1.1.0",
    # For Starlette's schema generation, would not be used with FastAPI
    "pyyaml >=5.3.1",
    # To validate email fields
    "email-validator >=2.0.0",
    # Uvicorn with uvloop
    "uvicorn[standard] >=0.12.0",
    # Settings management

**FastAPI** est basé sur **OpenAPI**.

C'est ce qui rend possibles plusieurs interfaces de documentation interactive automatiques, la génération de code, etc.

OpenAPI propose une manière de définir plusieurs « schémas » de sécurité.

      assertThat(allowedByCompactTable).isEqualTo(allowedByTable)
      assertThat(compactTableMappedTo).isEqualTo(tableMappedTo)
    }
  }

  /** Confirm we didn't corrupt any data in code generation. */
  @Test fun compareConstructedAndGeneratedCompactTables() {
    assertThat(IDNA_MAPPING_TABLE.sections).isEqualTo(compactTable.sections)
    assertThat(IDNA_MAPPING_TABLE.ranges).isEqualTo(compactTable.ranges)

            * **FastAPI** bunu doğrudan gömmek yerine OpenAPI'deki başka bir yerde bulunan global JSON Schema'lara bir referans ekler. Böylece diğer uygulamalar ve client'lar bu JSON Schema'ları doğrudan kullanabilir, daha iyi code generation araçları sağlayabilir, vb.
