You can optionally deploy your FastAPI app to <a href="https://fastapicloud.com" class="external-link" target="_blank">FastAPI Cloud</a>, go and join the waiting list if you haven't. 🚀

If you already have a **FastAPI Cloud** account (we invited you from the waiting list 😉), you can deploy your application with one command.

Before deploying, make sure you are logged in:

<div class="termy">

```console
$ fastapi login

ahead of the loop in this program:
</p>

<pre>
n := 0
for e := list; e != nil; e = e.next {
	n++
}
i := *p
*q = 1
</pre>

<p>
If <code>list</code> pointed to a cyclic list,
then the original program would never access <code>*p</code> or <code>*q</code>,
but the rewritten program would.

`convert_underscores`を`False`に設定する前に、HTTPプロキシやサーバの中にはアンダースコアを含むヘッダーの使用を許可していないものがあることに注意してください。

## ヘッダーの重複

受信したヘッダーが重複することがあります。つまり、同じヘッダーで複数の値を持つということです。

これらの場合、リストの型宣言を使用して定義することができます。

重複したヘッダーのすべての値をPythonの`list`として受け取ることができます。

例えば、複数回出現する可能性のある`X-Token`のヘッダを定義するには、以下のように書くことができます:

{* ../../docs_src/header_params/tutorial003.py hl[9] *}

もし、その*path operation*で通信する場合は、次のように２つのHTTPヘッダーを送信します:

```
X-Token: foo

     *
     * @param dictId the dictionary ID
     * @param body the search body containing pagination and filter parameters
     * @return JSON response containing list of stemmer override dictionary items
     */
    // GET /api/admin/dict/stemmerOverride/settings/{dictId}
    @Execute
    public JsonResponse<ApiResult> get$settings(final String dictId, final SearchBody body) {

    }.also { e ->
      assertEquals(firstFailure.toString(), e.toString())
    }
  }

  /** These tests are provided by [publicsuffix.org](https://publicsuffix.org/list/). */
  @Test
  fun publicSuffixDotOrgTestCases() {

    // Mixed case.

    printEvent("callEnd");
  }

  @Override public void dnsStart(Call call, String domainName) {
    printEvent("dnsStart");
  }

  @Override public void dnsEnd(Call call, String domainName, List<InetAddress> inetAddressList) {
    printEvent("dnsEnd");
  }

  ...
}
```

We make a couple calls:

```java
Request request = new Request.Builder()

| aud        | _string array_ | The token audience list. The client identifier of the OAuth clients that the JWT is intended for, is sent herewith.                                                                     |

	if !valResult.IsOk() {
		// Set to false if configuration fails to validate.
		l.LDAP.Enabled = false
		return l, valResult
	}

	return l, nil
}

// GetConfigList - returns a list of LDAP configurations.
func (l *Config) GetConfigList(s config.Config) ([]madmin.IDPListItem, error) {
	ldapConfigs, err := s.GetAvailableTargets(config.IdentityLDAPSubSys)
	if err != nil {
		return nil, err
	}

If `bump-pydantic` doesn't work for your use case, you can use the support for both Pydantic v1 and v2 models in the same app to do the migration to Pydantic v2 gradually.

You could fist upgrade Pydantic to use the latest version 2, and change the imports to use `pydantic.v1` for all your models.
