Để chạy bất kì ví dụ nào, sao chép code tới tệp tin `main.py`, và bắt đầu `uvicorn` với:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

## ❎ `python-jose`

👥 💪 ❎ `python-jose` 🏗 &amp; ✔ 🥙 🤝 🐍:

<div class="termy">

```console
$ pip install "python-jose[cryptography]"

`__name__ == "__main__"` 的主要目的是使用以下代码调用文件时执行一些代码：

<div class="termy">

```console
$ python myapp.py
```

</div>

而当其它文件导入它时并不会被调用，像这样：

```Python
from myapp import app
```

#### 更多细节

假设你的文件命名为 `myapp.py`。

如果你这样运行：

<div class="termy">

```console
$ python myapp.py
```

</div>

那么文件中由 Python 自动创建的内部变量 `__name__`，会将字符串 `"__main__"` 作为值。

Para rodar qualquer um dos exemplos, copie o codigo para um arquivo `main.py`, e inicie o `uvivorn` com:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

<div class="termy">

```console
$ pip install pytest

---> 100%
```

</div>

It will detect the files and tests automatically, execute them, and report the results back to you.

Run the tests with:

<div class="termy">

```console
$ pytest

================ test session starts ================

Wszystkie fragmenty kodu mogą być skopiowane bezpośrednio i użyte (są poprawnymi i przetestowanymi plikami).

Żeby wykonać każdy przykład skopiuj kod to pliku `main.py` i uruchom `uvicorn` za pomocą:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

All the code blocks can be copied and used directly (they are actually tested Python files).

To run any of the examples, copy the code to a file `main.py`, and start `fastapi dev` with:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

#!/bin/sh -e

../gradlew -q --console plain nativeImage

//// tab | 💾, 🇸🇻, 🚪 🎉

<div class="termy">

```console
// You could create an env var MY_NAME with
$ export MY_NAME="Wade Wilson"

// Then you could use it with other programs, like
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

//// tab | 🚪 📋

<div class="termy">

```console
// Create an env var MY_NAME
$ $Env:MY_NAME = "Wade Wilson"
