Then, with a URL like:

```
http://localhost:8000/items/?q=foo&q=bar
```

you would receive the multiple `q` *query parameters'* values (`foo` and `bar`) in a Python `list` inside your *path operation function*, in the *function parameter* `q`.

Тогда при таком URL:

```
http://localhost:8000/items/?q=foo&q=bar
```

вы получите множественные значения query-параметра `q` (`foo` и `bar`) в виде Python-`list` внутри вашей *функции обработки пути*, в *параметре функции* `q`.

/// tip | 提示

IP `0.0.0.0` 常用于指程序监听本机或服务器上的所有有效 IP。

API 文档还需要 OpenAPI 概图声明 API `server` 位于 `/api/v1`（使用代理时的 URL）。例如：

```JSON hl_lines="4-8"
{
    "openapi": "3.0.2",
    // More stuff here
    "servers": [
        {

它可能看起来是这样的:
