为此，`:80` 的后端必须有一个「允许的源」列表。

在这种情况下，它必须包含 `http://localhost:8080`，这样 `:8080` 的前端才能正常工作。

## 通配符 { #wildcards }

也可以使用 `"*"`（一个「通配符」）声明这个列表，表示全部都是允许的。

但这仅允许某些类型的通信，不包括所有涉及凭据的内容：比如 Cookies，以及那些使用 Bearer 令牌的 Authorization 请求头等。

因此，为了一切都能正常工作，最好显式地指定允许的源。

## 使用 `CORSMiddleware` { #use-corsmiddleware }

你可以在 **FastAPI** 应用中使用 `CORSMiddleware` 来配置它。

* 导入 `CORSMiddleware`。
* 创建一个允许的源列表（由字符串组成）。

   *
   * <p>Note that the cache <b>may evict an entry before this limit is exceeded</b>. For example, in
   * the current implementation, when {@code concurrencyLevel} is greater than {@code 1}, each
   * resulting segment inside the cache <i>independently</i> limits its own size to approximately
   * {@code maximumSize / concurrencyLevel}.
   *

Read the new docs: [Query Parameter Models](https://fastapi.tiangolo.com/tutorial/query-param-models/).

#### `Header` Parameter Models

Use Pydantic models for `Header` parameters:

```python
from typing import Annotated

from fastapi import FastAPI, Header
from pydantic import BaseModel

app = FastAPI()


class CommonHeaders(BaseModel):
    host: str

&.show { opacity: $modal-backdrop-opacity; }\n}\n\n// Modal header\n// Top section of the modal w/ title and dismiss\n.modal-header {\n  display: flex;\n  align-items: flex-start; // so the close btn always stays on the upper right corner\n  justify-content: space-between; // Put modal header elements (title and dismiss) on opposite ends\n  padding: $modal-header-padding;\n  border-bottom: $modal-header-border-width solid $modal-header-border-color;\n  @include border-top-radius($modal-content-i...

   *
   * @param a the first {@code long} to compare
   * @param b the second {@code long} to compare
   * @return a negative value if {@code a} is less than {@code b}; a positive value if {@code a} is
   *     greater than {@code b}; or zero if they are equal
   */
  @InlineMe(replacement = "Long.compare(a, b)")
  public static int compare(long a, long b) {
    return Long.compare(a, b);
  }

그리고 모든 메시지는 동일한 WebSocket 연결을 사용합니다.

## `Depends` 및 기타 사용하기 { #using-depends-and-others }

WebSocket 엔드포인트에서 `fastapi`에서 다음을 가져와 사용할 수 있습니다:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

이들은 다른 FastAPI 엔드포인트/*경로 처리*와 동일하게 동작합니다:
