### Step 3: Test on RabbitMQ

The python program below waits on the queue exchange `bucketevents` and prints event notifications on the console. We use [Pika Python Client](https://www.rabbitmq.com/tutorials/tutorial-three-python.html) library to do this.

```py
#!/usr/bin/env python
import pika

connection = pika.BlockingConnection(pika.ConnectionParameters(

# 🎻 📁

👆 💪 🍦 🎻 📁 🔁 ⚪️➡️ 📁 ⚙️ `StaticFiles`.

## ⚙️ `StaticFiles`

* 🗄 `StaticFiles`.
* "🗻" `StaticFiles()` 👐 🎯 ➡.

# 全局依赖项

有时，我们要为整个应用添加依赖项。

通过与定义[*路径装饰器依赖项*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} 类似的方式，可以把依赖项添加至整个 `FastAPI` 应用。

这样一来，就可以为所有*路径操作*应用该依赖项：

```Python hl_lines="15"
{!../../docs_src/dependencies/tutorial012.py!}
```

[*路径装饰器依赖项*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} 一章的思路均适用于全局依赖项， 在本例中，这些依赖项可以用于应用中的所有*路径操作*。

## 为一组路径操作定义依赖项

    sent to the client.

    Read more about it in the
    [FastAPI docs for Background Tasks](https://fastapi.tiangolo.com/tutorial/background-tasks/).

    ## Example

    ```python
    from fastapi import BackgroundTasks, FastAPI

    app = FastAPI()


    def write_notification(email: str, message=""):
        with open("log.txt", mode="w") as email_file:

## Das `Request`-Objekt direkt verwenden

Angenommen, Sie möchten auf die IP-Adresse/den Host des Clients in Ihrer *Pfadoperation-Funktion* zugreifen.

Dazu müssen Sie direkt auf den Request zugreifen.

### What is a Program

The word **program** is commonly used to describe many things:

* The **code** that you write, the **Python files**.
* The **file** that can be **executed** by the operating system, for example: `python`, `python.exe` or `uvicorn`.
* A particular program while it is **running** on the operating system, using the CPU, and storing things on memory. This is also called a **process**.

這也展現了他們對 FastAPI 和其**社群**（包括你）的真正承諾，他們不僅希望為你提供**優質的服務**，還希望確保你擁有一個**良好且健康的框架**：FastAPI。🙇

你可能會想嘗試他們的服務，以下有他們的指南：

The `status_code` parameter receives a number with the HTTP status code.

/// info

`status_code` can alternatively also receive an `IntEnum`, such as Python's <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

It will:

* Return that status code in the response.
