You actually don't have users that log in to your application but robots, bots, or other systems, that have just an access token? Again, it all works the same.

Just use any kind of model, any kind of class, any kind of database that you need for your application. **FastAPI** has you covered with the dependency injection system.

## Code size { #code-size }

檔案與表單欄位會作為表單資料上傳，而你將能接收到這些檔案與欄位。

你也可以將部分檔案宣告為 `bytes`，另一些宣告為 `UploadFile`。

/// warning

你可以在一個路徑操作 (path operation) 中宣告多個 `File` 與 `Form` 參數，但不能同時再宣告預期以 JSON 接收的 `Body` 欄位，因為該請求的本文會使用 `multipart/form-data` 而非 `application/json` 進行編碼。

這不是 **FastAPI** 的限制，這是 HTTP 通訊協定本身的規範。

## 小結 { #recap }

        def fetch_credentials():
            # HTTP headers are case insensitive filter out
            # all duplicate headers and pick one.
            headers = {}
            headers['content-type'] = 'application/x-www-form-urlencoded'
            headers['authorization'] = urllib3.make_headers(
                basic_auth='%s:%s' % (self.cid, self.csec))['authorization']

            response = self._http.urlopen('POST', self.idp_ep,

/**

    public RootAction() {

/** Authorization for an application to make Slack API calls on behalf of a user. */
@SuppressWarnings("checkstyle:membername")
public final class OAuthSession {
  public final boolean ok;
  public final String access_token;
  public final String scope;

Ви можете оголосити кілька параметрів `File` і `Form` в операції *шляху*, але не можете одночасно оголошувати `Body`-поля, які очікуєте отримати у форматі JSON, оскільки запит матиме тіло, закодоване за допомогою `multipart/form-data`, а не `application/json`.

Це не обмеження **FastAPI**, а частина протоколу HTTP.

Es **ALTAMENTE recomendable** que escribas o copies el código, lo edites y lo ejecutes localmente.

コードを記述またはコピーし、編集してローカルで実行することを**強く推奨します**。

エディターで使用することで、書く必要のあるコードの少なさ、すべての型チェック、自動補完など、FastAPIの利点を本当に実感できます。
