    * A "token" is just a string with some content that we can use later to verify this user.
    * Normally, a token is set to expire after some time.
        * So, the user will have to log in again at some point later.
        * And if the token is stolen, the risk is less. It is not like a permanent key that will work forever (in most of the cases).
* The frontend stores that token temporarily somewhere.

```Python
commons: CommonQueryParams = Depends()
```

////

You declare the dependency as the type of the parameter, and you use `Depends()` without any parameter, instead of having to write the full class *again* inside of `Depends(CommonQueryParams)`.

The same example would then look like:

{* ../../docs_src/dependencies/tutorial004_an_py310.py hl[19] *}

...and **FastAPI** will know what to do.

    * Наприклад, `await myfile.seek(0)` поверне курсор на початок файлу.
    * This is especially useful if you run `await myfile.read()` once and then need to read the contents again. Це особливо корисно, якщо Ви виконуєте await `await myfile.read()` один раз, а потім потрібно знову прочитати вміст.
* `close()`: Закриває файл.

Оскільки всі ці методи є асинхронними `async`, Вам потрібно використовувати "await":

  shopt -s expand_aliases
else
  echo '==TFCI==: Error: Cannot find path to grealpath or gstat'
  echo 'TF CI scripts require GNU core utilties to be installed. Please make'
  echo 'sure they are present on your system and try again.'
  exit 1

# "TFCI_MACOS_BAZEL_TEST_DIR_PATH" specifies the directory that Bazel should use
# when running tests. Each test will be executed in a separate subdirectory

### Include the custom docs for static files { #include-the-custom-docs-for-static-files }

And the same way as with a custom CDN, now you can create the *path operations* for the custom docs.

Again, you can reuse FastAPI's internal functions to create the HTML pages for the docs, and pass them the needed arguments:
