You will see examples of this in the next chapters, about relational and NoSQL databases, security, etc.

## **FastAPI** compatibility { #fastapi-compatibility }

The simplicity of the dependency injection system makes **FastAPI** compatible with:

* all the relational databases
* NoSQL databases
* external packages
* external APIs
* authentication and authorization systems
* API usage monitoring systems

 * or obfuscated with tools like R8 or ProGuard. In such cases it'll return a longer string like
 * "com.example.shaded.okhttp3.OkHttp". In large applications it's possible to have multiple OkHttp
 * instances; this makes it clear which is which.

OkHttp
======

See the [project website][okhttp] for documentation and APIs.

HTTP is the way modern applications network. It’s how we exchange data & media. Doing HTTP
efficiently makes your stuff load faster and saves bandwidth.

OkHttp is an HTTP client that’s efficient by default:

 * HTTP/2 support allows all requests to the same host to share a socket.
 * Connection pooling reduces request latency (if HTTP/2 isn’t available).

  }

  /**
   * Similar to load64, but allows offset + 8 > input.length, padding the result with zeroes. This
   * has to explicitly reverse the order of the bytes as it packs them into the result which makes
   * it slower than the native version.
   *
   * @param input the input bytes
   * @param offset the offset into the array at which to start reading
   * @param length the number of bytes from the input to read

但是后面我们在路径操作函数的参数 `commons` 中得到了一个 `dict`。

我们知道编辑器不能为 `dict` 提供很多支持(比如补全)，因为编辑器不知道 `dict` 的键和值类型。

对此，我们可以做的更好...

## 什么构成了依赖项 { #what-makes-a-dependency }

到目前为止，你看到的依赖项都被声明为函数。

但这并不是声明依赖项的唯一方法(尽管它可能是更常见的方法)。

关键因素是依赖项应该是 "可调用对象"。

Python 中的 "**可调用对象**" 是指任何 Python 可以像函数一样 "调用" 的对象。

所以，如果你有一个对象 `something` (可能*不是*一个函数)，你可以 "调用" 它(执行它)，就像：

            return;
        }

        // Convert modules element to subprojects
        Element modulesElement = root.child(MODULES).orElse(null);
        if (modulesElement != null) {
            // domtrip makes this much simpler - just change the element name
            // The formatting and structure are preserved automatically
            modulesElement.name(SUBPROJECTS);
