# Deploy FastAPI on Cloud Providers

You can use virtually **any cloud provider** to deploy your FastAPI application.

In most of the cases, the main cloud providers have guides to deploy FastAPI with them.

## Cloud Providers - Sponsors

Some cloud providers ✨ [**sponsor FastAPI**](../help-fastapi.md#sponsor-the-author){.internal-link target=_blank} ✨, this ensures the continued and healthy **development** of FastAPI and its **ecosystem**.

from fastapi.testclient import TestClient

from .main import app

client = TestClient(app)


def test_read_item():
    response = client.get("/items/foo", headers={"X-Token": "coneofsilence"})
    assert response.status_code == 200
    assert response.json() == {
        "id": "foo",
        "title": "Foo",
        "description": "There goes my hero",
    }


def test_read_item_bad_token():

from fastapi.testclient import TestClient

from .main import app

client = TestClient(app)


def test_read_item():
    response = client.get("/items/foo", headers={"X-Token": "coneofsilence"})
    assert response.status_code == 200
    assert response.json() == {
        "id": "foo",
        "title": "Foo",
        "description": "There goes my hero",
    }


def test_read_item_bad_token():

      println(response.body.string())
    }
  }

  companion object {
    val MEDIA_TYPE_MARKDOWN = "text/x-markdown; charset=utf-8".toMediaType()
  }
}

fun main() {
  PostString().run()

다음과 같이 표시됩니다.

Pycharm을 사용하는 경우 다음을 수행할 수 있습니다

* "Run" 메뉴를 엽니다
* "Debug..." 옵션을 선택합니다.
* 그러면 상황에 맞는 메뉴가 나타납니다.
* 디버그할 파일을 선택합니다(이 경우 `main.py`).

그런 다음 **FastAPI** 코드로 서버를 시작하고 중단점 등에서 중지합니다.

다음과 같이 표시됩니다.

      for (certificate in response.handshake!!.peerCertificates) {
        println(CertificatePinner.pin(certificate))
      }
    }
  }
}

fun main() {
  CertificatePinning().run()

```

<details markdown="1">
<summary><code>uvicorn main:app --reload</code> 명령에 관하여...</summary>

명령 `uvicorn main:app`은 다음을 나타냅니다:

* `main`: `main.py` 파일 (파이썬 "모듈").
* `app`: the object created inside of `main.py` with the line `app = FastAPI()`.
* `--reload`: 코드가 변경된 후 서버 재시작하기. 개발환경에서만 사용하십시오.

</details>

### 확인하기

That way, you can edit the documentation/source files and see the changes live.

/// tip

Alternatively, you can perform the same steps that scripts does manually.

Go into the language directory, for the main docs in English it's at `docs/en/`:

```console
$ cd docs/en/
```

Then run `mkdocs` in that directory:

```console
$ mkdocs serve --dev-addr 8008
```

///

 * overriding going on amongst the models being used in this test:
 * each model in the lineage is providing a value that is not present
 * anywhere else in the lineage. We are just making sure that values
 * down in the lineage are bubbling up where they should.
 *

バイナリやテキストデータ、JSONデータを送受信できます。

## 試してみる

ファイル名が `main.py` である場合、以下の方法でアプリケーションを実行します。

<div class="termy">

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