These are any `OPTIONS` request with `Origin` and `Access-Control-Request-Method` headers.

In this case the middleware will intercept the incoming request and respond with appropriate CORS headers, and either a `200` or `400` response for informational purposes.

### Simple requests

Any request with an `Origin` header. In this case the middleware will pass the request through as normal, but will include appropriate CORS headers on the response.

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

Qualquer solicitação com um cabeçalho `Origin`. Neste caso, o middleware passará a solicitação normalmente, mas incluirá cabeçalhos CORS apropriados na resposta.

                </mxCell>
                <mxCell id="5" value="" style="rounded=0;whiteSpace=wrap;html=1;fontStyle=1;strokeWidth=4;" parent="1" vertex="1">
                    <mxGeometry x="1030" y="430" width="400" height="260" as="geometry"/>
                </mxCell>

中间件响应两种特定类型的 HTTP 请求……

### CORS 预检请求

这是些带有 `Origin` 和 `Access-Control-Request-Method` 请求头的 `OPTIONS` 请求。

在这种情况下，中间件将拦截传入的请求并进行响应，出于提供信息的目的返回一个使用了适当的 CORS headers 的 `200` 或 `400` 响应。

### 简单请求

任何带有 `Origin` 请求头的请求。在这种情况下，中间件将像平常一样传递请求，但是在响应中包含适当的 CORS headers。
