`Headers` class offers full access to the HTTP headers.

 *  **Okio dependency added.** OkHttp now depends on
    [Okio](https://github.com/square/okio), an I/O library that makes it easier
    to access, store and process data. Using this library internally makes OkHttp
    faster while consuming less memory. You can write a `RequestBody` as an Okio
    `BufferedSink` and a `ResponseBody` as an Okio `BufferedSource`. Standard

                    logger.warn("Not Found for SearchLog: {}", clickLog);
                });
            } catch (final Exception e) {
                logger.warn("Failed to process: {}", clickLog, e);
            }
        }
        processClickLog(clickLogList);

        updateClickFieldInIndex(clickCountMap);

And you can use directly many well maintained and widely used packages like `passlib` and `PyJWT`, because **FastAPI** doesn't require any complex mechanisms to integrate external packages.

But it provides you the tools to simplify the process as much as possible without compromising flexibility, robustness, or security.

And you can use and implement secure, standard protocols, like OAuth2 in a relatively simple way.

Це означає:

* Змінна `prices` це `dict`:
    * Ключі цього `dict` типу `str` (наприклад, назва кожного елементу).
    * Значення цього `dict` типу `float` (наприклад, ціна кожного елементу).

#### Union (об'єднання)

* Hỗ trợ **WebSocket**.
* In-process background tasks.
* Startup and shutdown events.
* Client cho kiểm thử xây dựng trên HTTPX.
* **CORS**, GZip, Static Files, Streaming responses.
* Hỗ trợ **Session and Cookie**.
* 100% test coverage.

#### 字典

定义 `dict` 时，需要传入两个子类型，用逗号进行分隔。

第一个子类型声明 `dict` 的所有键。

第二个子类型声明 `dict` 的所有值：

```Python hl_lines="1  4"
{!../../docs_src/python_types/tutorial008.py!}
```

这表示：

* 变量 `prices` 是一个 `dict`：
    * 这个 `dict` 的所有键为 `str` 类型（可以看作是字典内每个元素的名称）。
    * 这个 `dict` 的所有值为 `float` 类型（可以看作是字典内每个元素的价格）。

### 类作为类型

你也可以将类声明为变量的类型。

假设你有一个名为 `Person` 的类，拥有 name 属性：

    asByteSource(from).copyTo(to);
  }

  /**
   * Copies all the bytes from one file to another.
   *
   * <p>Copying is not an atomic operation - in the case of an I/O error, power loss, process
   * termination, or other problems, {@code to} may not be a complete copy of {@code from}. If you
   * need to guard against those conditions, you should employ other file-level synchronization.
   *
