# Custom Response Classes - File, HTML, Redirect, Streaming, etc.

There are several custom response classes you can use to create an instance and return them directly from your *path operations*.

Read more about it in the [FastAPI docs for Custom Response - HTML, Stream, File, others](https://fastapi.tiangolo.com/advanced/custom-response/).

You can import them directly from `fastapi.responses`:

```python
from fastapi.responses import (
    FileResponse,

	return func(network, address string, c syscall.RawConn) error {
		return nil
	}
}

// DialContext is a function to make custom Dial for internode communications
type DialContext func(ctx context.Context, network, address string) (net.Conn, error)

// NewInternodeDialContext configures a custom dialer for internode communications
func NewInternodeDialContext(dialTimeout time.Duration, _ TCPOptions) DialContext {

    cniNetnsDir: # Defaults to '/var/run/netns', in minikube/docker/others can be '/var/run/docker/netns'.


    excludeNamespaces:
      - kube-system

    # Allows user to set custom affinity for the DaemonSet
    affinity: {}

    # Custom annotations on pod level, if you need them
    podAnnotations: {}

    # Deploy the config files as plugin chain (value "true") or as standalone files in the conf dir (value "false")?

from dirty_equals import IsDict
from fastapi.testclient import TestClient

from docs_src.custom_request_and_route.tutorial002 import app

client = TestClient(app)


def test_endpoint_works():
    response = client.post("/", json=[1, 2, 3])
    assert response.json() == 6


def test_exception_handler_body_access():
    response = client.post("/", json={"numbers": [1, 2, 3]})
    assert response.json() == IsDict(
        {

Nevertheless, we can declare the expected schema for the request body.

### Custom OpenAPI content type

Using this same trick, you could use a Pydantic model to define the JSON Schema that is then included in the custom OpenAPI schema section for the *path operation*.

And you could do this even if the data type in the request is not JSON.
