**FastAPI** 提供了以下内容：

### 基于开放标准


* 用于创建 API 的 <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank"><strong>OpenAPI</strong></a> 包含了<abbr title="也被叫做: endpoints, routes">路径</abbr><abbr title="也叫做HTTP方法, 例如 POST, GET, PUT, DELETE">操作</abbr>，请求参数，请求体，安全性等的声明。
* 使用 <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (因为 OpenAPI 本身就是基于 JSON Schema 的)自动生成数据模型文档。

from pydantic import BaseModel, Field


class MessageEventType(str, Enum):
    alpha = "alpha"
    beta = "beta"


class MessageEvent(BaseModel):
    event_type: MessageEventType = Field(default=MessageEventType.alpha)
    output: str


class MessageOutput(BaseModel):
    body: str = ""
    events: list[MessageEvent] = []


class Message(BaseModel):
    input: str
    output: MessageOutput

            session.setSession(defaultSessionFactory.newSession(session));

            sessionScope.seed(MavenSession.class, session);
            sessionScope.seed(Session.class, session.getSession());
            sessionScope.seed(InternalMavenSession.class, InternalMavenSession.from(session.getSession()));

            legacySupport.setSession(session);

Hier werden wir ein Beispiel mit <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel</a> sehen.
