## ❎ FastAPI

🥇 🔁 ❎ FastAPI.

🔰, 👆 💪 💚 ❎ ⚫️ ⏮️ 🌐 📦 🔗 &amp; ⚒:

<div class="termy">

```console
$ pip install "fastapi[all]"

---> 100%
```

</div>

...👈 🔌 `uvicorn`, 👈 👆 💪 ⚙️ 💽 👈 🏃 👆 📟.

Make sure you create a [virtual environment](../../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

/// info

If you are planning to use digital signature algorithms like RSA or ECDSA, you should install the cryptography library dependency `pyjwt[crypto]`.

                    out.print("</b></a><div align='right'>");
                    out.print(f.length() / 1024 + " KB </div><div>");
                    i = name.lastIndexOf('.') + 1;
                    if (i > 1 && name.length() - i < 6) {
                        out.print(name.substring(i).toUpperCase() + "</div class='ext'>");
                    } else {
                        out.print("&nbsp;</div>");
                    }

## Executá-lo

Você pode executar os seus testes normalmente via:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## Em Detalhes

O marcador `@pytest.mark.anyio` informa ao pytest que esta função de teste deve ser invocada de maneira assíncrona:

    response.append(String.format("<h1>%s</h1>", basePath));
    for (String file : directory.list()) {
      response.append(String.format("<div class='file'><a href='%s'>%s</a></div>",
          basePath + file, file));
    }
    response.append("</body></html>");

    return new MockResponse()
        .setStatus("HTTP/1.1 200")

برنامه را با استفاده از ‘uvicorn‘ اجرا کنید، اگر فایل شما ‘main.py‘ نام دارد، دستور زیر را وارد کنید:
<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)
```

</div>
