#### `RequestValidationError`と`ValidationError`

/// warning | 注意

これらは今のあなたにとって重要でない場合は省略しても良い技術的な詳細です。

///

`RequestValidationError`はPydanticの<a href="https://docs.pydantic.dev/latest/concepts/models/#error-handling" class="external-link" target="_blank">`ValidationError`</a>のサブクラスです。

**FastAPI** は`response_model`でPydanticモデルを使用していて、データにエラーがあった場合、ログにエラーが表示されるようにこれを使用しています。

1. 直接将`main.py`文件复制到`/code`目录中（不包含任何`./app`目录）。

2. 运行 Uvicorn 并告诉它从 `main` 导入 `app` 对象（而不是从 `app.main` 导入）。

然后调整Uvicorn命令使用新模块`main`而不是`app.main`来导入FastAPI 实例`app`。

## 部署概念

我们再谈谈容器方面的一些相同的[部署概念](concepts.md){.internal-link target=_blank}。

容器主要是一种简化**构建和部署**应用程序的过程的工具，但它们并不强制执行特定的方法来处理这些**部署概念**，并且有几种可能的策略。

**好消息**是，对于每种不同的策略，都有一种方法可以涵盖所有部署概念。 🎉

让我们从容器的角度回顾一下这些**部署概念**：

* HTTPS
* 启动时运行

      return INSTANCE;
    }

    @GwtIncompatible @J2ktIncompatible private static final long serialVersionUID = 1;
  }

  /**
   * Returns a serializable converter object that converts between strings and integers using {@link
   * Integer#decode} and {@link Integer#toString()}. The returned converter throws {@link
   * NumberFormatException} if the input string is invalid.
   *

  // To avoid a self retain cycle under j2objc, we store Optional.absent() instead of
  // Optional.of(this). To access the delegate iterable, call #getDelegate(), which converts to
  // absent() back to 'this'.
  private final Optional<Iterable<E>> iterableDelegate;

  /** Constructor for use by subclasses. */
  protected FluentIterable() {
    this.iterableDelegate = Optional.absent();
