Framing rules make it impractical to implement http/2 correctly on a single blocking thread. The flow-control features introduce feedback between reads and writes, requiring writes to acknowledge reads and reads to throttle writes.

In OkHttp we expose a blocking API over a framed protocol. This document explains the code and policy that makes that work.

### Threads

#### Application's calling thread

   *       to make such changes to our serialized forms, and we have made them before, usually
   *       without trouble. In this case, my guess is that our chosen approach is even less likely
   *       to lead to trouble than an incompatible change would be.
   *   <li>We could make {@link #countMap} no longer be {@code final}. Then we could write to it

        // TODO: Staging directory should be a part of the Javadocs extension
        // TODO: Pull out more of this configuration into the extension if it makes sense
        // TODO: in a typical project, this may need to be the regular javadoc task vs javadocAll

        var groovyPackageListBucket = project.getConfigurations().dependencyScope("groovyPackageListBucket");

### Retrieving Container ID

To use Docker commands on a specific container, you need to know the `Container ID` for that container. To get the `Container ID`, run

```sh
docker ps -a
```

`-a` flag makes sure you get all the containers (Created, Running, Exited). Then identify the `Container ID` from the output.

### Starting and Stopping Containers

`OAuth2PasswordBearer` makes **FastAPI** know that it is a security scheme. So it is added that way to OpenAPI.

But `OAuth2PasswordRequestForm` is just a class dependency that you could have written yourself, or you could have declared `Form` parameters directly.

But as it's a common use case, it is provided by **FastAPI** directly, just to make it easier.

但接著我們在路徑操作函式（*path operation function*）的參數 `commons` 中取得的是一個 `dict`。

而我們知道，編輯器對 `dict` 無法提供太多輔助（例如自動完成），因為它無法預先知道其中的鍵與值的型別。

我們可以做得更好...

## 什麼算是相依性 { #what-makes-a-dependency }

到目前為止，你看到的相依性都是宣告成函式。

但那不是宣告相依性的唯一方式（雖然那大概是最常見的）。

關鍵在於，相依性應該要是「callable」。

在 Python 中，「**callable**」指的是任何可以像函式一樣被 Python「呼叫」的東西。

因此，如果你有一個物件 `something`（它可能不是函式），而你可以像這樣「呼叫」（執行）它：

    OkHttp used _get_ and _set_ prefixes sporadically which make the API
    inconsistent and awkward to explore.

 *  **OkHttpClient now implements the new `Call.Factory` interface.** This
    interface will make your code easier to test. When you test code that makes
    HTTP requests, you can use this interface to replace the real `OkHttpClient`
    with your own mocks or fakes.

하지만 그러면 *경로 처리 함수*의 매개변수 `commons`에서 `dict`를 받게 됩니다.

그리고 에디터는 `dict`의 키와 값 타입을 알 수 없기 때문에 `dict`에 대해서는 (완성 기능 같은) 많은 지원을 제공할 수 없다는 것을 알고 있습니다.

더 나은 방법이 있습니다...

## 의존성이 되기 위한 조건 { #what-makes-a-dependency }

지금까지는 함수로 선언된 의존성을 봤습니다.

하지만 그것만이 의존성을 선언하는 유일한 방법은 아닙니다(아마도 더 일반적이긴 하겠지만요).

핵심 요소는 의존성이 "호출 가능(callable)"해야 한다는 것입니다.

파이썬에서 "**호출 가능(callable)**"이란 파이썬이 함수처럼 "호출"할 수 있는 모든 것입니다.
