But for the generated client we could **modify** the OpenAPI operation IDs right before generating the clients, just to make those method names nicer and **cleaner**.

We could download the OpenAPI JSON to a file `openapi.json` and then we could **remove that prefixed tag** with a script like this:

//// tab | Python

```Python

* 创建一个允许的源列表（由字符串组成）。
* 将其作为「中间件」添加到你的 **FastAPI** 应用中。

你也可以指定后端是否允许：

* 凭证（授权 headers，Cookies 等）。
* 特定的 HTTP 方法（`POST`，`PUT`）或者使用通配符 `"*"` 允许所有方法。
* 特定的 HTTP headers 或者使用通配符 `"*"` 允许所有 headers。

```Python hl_lines="2  6-11  13-19"
{!../../docs_src/cors/tutorial001.py!}
```

默认情况下，这个 `CORSMiddleware` 实现所使用的默认参数较为保守，所以你需要显式地启用特定的源、方法或者 headers，以便浏览器能够在跨域上下文中使用它们。

支持以下参数：

labels.roletype_title_details=Role
labels.roletype_name=Name
labels.roletype_value=Value
labels.reqheader_configuration=Request Header
labels.reqheader_list_name=Name
labels.reqheader_list_web_crawling_config=Config Name
labels.reqheader_create_web_config=Create New Web Config
labels.reqheader_title_details=Request Header
labels.reqheader_name=Name
labels.reqheader_value=Value
labels.reqheader_web_crawling_config=Web Config
