-   In such situations, we may request you to make further changes to your PR
    for the tests to pass.
-   Once the tests pass, we now bring all the code into the internal code base,
    using a job called "copybara".

**5. Copy to Google Internal codebase and run internal CI**

-   Once the PR is in the Google codebase, we make sure it integrates well with
    its dependencies and the rest of the system.

    - Copy the OAuth Client Key as the value for `<CLIENT_ID>`.
    - Copy the OAuth Client Secret as the value for `<CLIENT_SECRET>`.
  - By default, `<IS_HOST>` is localhost. However, if using a public IP, the respective IP address or domain needs to be specified.
  - By default, `<IS_HTTPS_PORT>` has been set to 9443. However, if the port offset has been incremented by n, the default port value needs to be incremented by n.

You can send (and receive) many messages:

<img src="/img/tutorial/websockets/image04.png">

And all of them will use the same WebSocket connection.

## Using `Depends` and others { #using-depends-and-others }

In WebSocket endpoints you can import from `fastapi` and use:

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

要運行任何範例，請將程式碼複製到 `main.py` 檔案，並使用以下命令啟動 `fastapi dev`：
