/// note | 技术细节

`Request` 拥有 `request.scope` 属性，它就是一个 Python `dict`，包含与请求相关的元数据。

`Request` 还包含 `request.receive`，它是一个用于“接收”请求体的函数。

`scope` 字典和 `receive` 函数都是 ASGI 规范的一部分。

创建一个新的 `Request` 实例需要这两样：`scope` 和 `receive`。

想了解更多关于 `Request` 的信息，请查看 [Starlette 的 Request 文档](https://www.starlette.dev/requests/)。

///

	// use that and validate the authentication request. If not, we assume this
	// is an STS request for a claim based IDP (if one is present) and set
	// roleArn = openid.DummyRoleARN.
	//
	// Currently, we do not support multiple claim based IDPs, as there is no
	// defined parameter to disambiguate the intended IDP in this STS request.
	roleArn := openid.DummyRoleARN

This is the case for most of the web applications.

Many, many users, but your server is waiting 🕙 for their not-so-good connection to send their requests.

And then waiting 🕙 again for the responses to come back.

This "waiting" 🕙 is measured in microseconds, but still, summing it all, it's a lot of waiting in the end.

Ele também cuidará da maioria das coisas de que você precisaria ao implantar uma aplicação, como:

* HTTPS
* Replicação, com dimensionamento automático baseado em requests
* etc.

### Requisições CORS pré-voo (preflight) { #cors-preflight-requests }

Estas são quaisquer solicitações `OPTIONS` com cabeçalhos `Origin` e `Access-Control-Request-Method`.

Nesse caso, o middleware interceptará a solicitação recebida e responderá com cabeçalhos CORS apropriados e uma resposta `200` ou `400` para fins informativos.

### Requisições Simples { #simple-requests }

// proxyTaggingToRepTarget proxies tagging requests to remote targets for
// active-active replicated setups
func proxyTaggingToRepTarget(ctx context.Context, bucket, object string, tags *tags.Tags, opts ObjectOptions, proxyTargets *madmin.BucketTargets) (proxy proxyResult) {
	// this option is set when active-active replication is in place between site A -> B,
	// and request hits site B that does not have the object yet.

/// note | Технічні деталі

У `Request` є атрибут `request.scope` - це просто Python `dict`, що містить метадані, пов'язані із запитом.

Також `Request` має `request.receive` - це функція для «отримання» тіла запиту.

`scope` `dict` і функція `receive` є частиною специфікації ASGI.

І саме ці дві сутності - `scope` та `receive` - потрібні для створення нового екземпляра `Request`.

Bazı kullanım senaryoları:

* JSON olmayan request body'leri JSON'a dönüştürmek (örn. [`msgpack`](https://msgpack.org/index.html)).
* gzip ile sıkıştırılmış request body'leri açmak (decompress).
* Tüm request body'lerini otomatik olarak loglamak.

## Özel request body encoding'lerini ele alma { #handling-custom-request-body-encodings }

Gzip request'lerini açmak için özel bir `Request` alt sınıfını nasıl kullanabileceğimize bakalım.

     * Get the value for the key 'rate.limit.requests.per.window'. <br>
     * The value is, e.g. 100 <br>
     * comment: Maximum number of requests allowed per window.
     * @return The value of found property. (NotNull: if not found, exception but basically no way)
     */
    String getRateLimitRequestsPerWindow();

    /**
     * Get the value for the key 'rate.limit.requests.per.window' as {@link Integer}. <br>

También se encargará de la mayoría de las cosas que necesitas al desplegar una app, como:

* HTTPS
* Replicación, con autoescalado basado en requests
* etc.
