尽管如此，我们仍然可以声明请求体的预期方案。

### 自定义 OpenAPI 内容类型 { #custom-openapi-content-type }

使用同样的技巧，你可以用一个 Pydantic 模型来定义 JSON Schema，然后把它包含到该 *路径操作* 的自定义 OpenAPI 方案部分中。

即使请求中的数据类型不是 JSON，你也可以这样做。

例如，在这个应用中我们不使用 FastAPI 集成的从 Pydantic 模型提取 JSON Schema 的功能，也不使用对 JSON 的自动校验。实际上，我们将请求的内容类型声明为 YAML，而不是 JSON：

    // GET /api/admin/accesstoken
    // PUT /api/admin/accesstoken
    /**
     * Retrieves a list of access token settings.
     *
     * @param body the search body containing filter criteria
     * @return JSON response with access token list
     */
    @Execute
    public JsonResponse<ApiResult> settings(final SearchBody body) {
        validateApi(body, messages -> {});

):
    pass  # pragma: no cover


client = TestClient(app)


def test_openapi_schema():
    response = client.get("/openapi.json")
    assert response.status_code == 200, response.text
    assert response.json() == snapshot(
        {
            "openapi": "3.1.0",
            "info": {"title": "FastAPI", "version": "0.1.0"},
