# Body - Multiple Parameters

Now that we have seen how to use `Path` and `Query`, let's see more advanced uses of request body declarations.

## Mix `Path`, `Query` and body parameters

First, of course, you can mix `Path`, `Query` and request body parameter declarations freely and **FastAPI** will know what to do.

And you can also declare body parameters as optional, by setting the default to `None`:

=== "Python 3.10+"

        this.hostname = value;
    }

    public String getParameters() {
        checkSpecifiedProperty("parameters");
        return convertEmptyToNull(parameters);
    }

    public void setParameters(String value) {
        registerModifiedProperty("parameters");
        this.parameters = value;
    }

    public String getPassword() {
        checkSpecifiedProperty("password");

  /** True if the agreed upon extension parameters includes "client_no_context_takeover". */
  @JvmField val clientNoContextTakeover: Boolean = false,
  /** Should be a value in [8..15]. Any value in that range is acceptable by OkHttp. */
  @JvmField val serverMaxWindowBits: Int? = null,
  /** True if the agreed upon extension parameters includes "server_no_context_takeover". */

Um diese zu konfigurieren, übergeben Sie das Argument `swagger_ui_parameters` beim Erstellen des `FastAPI()`-App-Objekts oder an die Funktion `get_swagger_ui_html()`.

`swagger_ui_parameters` empfängt ein Dict mit den Konfigurationen, die direkt an die Swagger-Oberfläche übergeben werden.

# Cookie Parameters

You can define Cookie parameters the same way you define `Query` and `Path` parameters.

## Import `Cookie`

First import `Cookie`:

        this.hostname = value;
    }

    public String getParameters() {
        checkSpecifiedProperty("parameters");
        return convertEmptyToNull(parameters);
    }

    public void setParameters(String value) {
        registerModifiedProperty("parameters");
        this.parameters = value;
    }

    public String getPassword() {
        checkSpecifiedProperty("password");

        val ignoreIncomingBuildReceipt: Property<Boolean>

        @get:Optional
        val buildReceiptFileContents: Property<String>
    }

    override fun obtain(): String? = parameters.run {
        buildReceiptString()
