your build system.

    OkHttp will use Conscrypt if you set the `okhttp.platform` system property
    to `conscrypt`.

    Alternatively, OkHttp will also use Conscrypt if you install it as your
    preferred security provider. To do so, add the following code to execute
    before you create your `OkHttpClient`.

    ```
    Security.insertProviderAt(

This gives you a lot of flexibility. You can return any data type, override any data declaration or validation, etc.

## Using the `jsonable_encoder` in a `Response` { #using-the-jsonable-encoder-in-a-response }

Because **FastAPI** doesn't make any changes to a `Response` you return, you have to make sure its contents are ready for it.

## Use `CORSMiddleware` { #use-corsmiddleware }

You can configure it in your **FastAPI** application using the `CORSMiddleware`.

* Import `CORSMiddleware`.
* Create a list of allowed origins (as strings).
* Add it as a "middleware" to your **FastAPI** application.

You can also specify whether your backend allows:

* Credentials (Authorization headers, Cookies, etc).

   * {@link #escape(int)} for each of them. If the semantics of your escaper are such that code
   * points in the supplementary range are either all escaped or all unescaped, this method can be
   * implemented more efficiently using {@link CharSequence#charAt(int)}.
   *
   * <p>Note however that if your escaper does not escape characters in the supplementary range, you

   * {@link #escape(int)} for each of them. If the semantics of your escaper are such that code
   * points in the supplementary range are either all escaped or all unescaped, this method can be
   * implemented more efficiently using {@link CharSequence#charAt(int)}.
   *
   * <p>Note however that if your escaper does not escape characters in the supplementary range, you

## Use it { #use-it }

Now you can declare your dependency using this class.

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

**FastAPI** calls the `CommonQueryParams` class. This creates an "instance" of that class and the instance will be passed as the parameter `commons` to your function.
