browser = playwright.chromium.launch(headless=False)
    context = browser.new_context(viewport={"width": 960, "height": 1080})
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_text("POST/items/Create Item").click()
    page.get_by_role("tab", name="Schema").first.click()

Now you can create the *path operations* for the custom docs.

You can re-use FastAPI's internal functions to create the HTML pages for the docs, and pass them the needed arguments:

* `openapi_url`: the URL where the HTML page for the docs can get the OpenAPI schema for your API. You can use here the attribute `app.openapi_url`.
* `title`: the title of your API.
* `oauth2_redirect_url`: you can use `app.swagger_ui_oauth2_redirect_url` here to use the default.

    context = browser.new_context(viewport={"width": 960, "height": 1080})
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_role("button", name="Item-Input").click()
    page.get_by_role("button", name="Item-Output").click()
    page.set_viewport_size({"width": 960, "height": 820})
    page.screenshot(
        path="docs/en/docs/img/tutorial/separate-openapi-schemas/image04.png"
    )

def on_pre_page(page: Page, *, config: MkDocsConfig, files: Files) -> Page:
    return page


def on_page_markdown(
    markdown: str, *, page: Page, config: MkDocsConfig, files: Files
) -> str:
    if isinstance(page.file, EnFile):
        for excluded_section in non_traslated_sections:
            if page.file.src_path.startswith(excluded_section):

    browser = playwright.chromium.launch(headless=False)
    context = browser.new_context(viewport={"width": 960, "height": 1080})
    page = context.new_page()
    page.goto("http://localhost:8000/docs")
    page.get_by_role("button", name="Item", exact=True).click()
    page.set_viewport_size({"width": 960, "height": 700})
    page.screenshot(
        path="docs/en/docs/img/tutorial/separate-openapi-schemas/image05.png"
    )

## 使用 CLI 登录

现在，使用 CLI 登录 Deta：

<div class="termy">

```console
$ deta login

Please, log in from the web page. Waiting..
Logged in successfully.
```

</div>

这个命令会打开浏览器并自动验证身份。

## 使用 Deta 部署

接下来，使用 Deta CLI 部署应用：

<div class="termy">

```console
$ deta new

<mxfile host="65bd71144e">
    <diagram id="jyERGzDynktFHFRGN0ph" name="Page-1">
