For example, to declare a header of `X-Token` that can appear more than once, you can write:

{* ../../docs_src/header_params/tutorial003_an_py310.py hl[9] *}

If you communicate with that *path operation* sending two HTTP headers like:

```
X-Token: foo
X-Token: bar
```

The response would be like:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

def test_read_nonexistent_item():
    response = client.get("/items/baz", headers={"X-Token": "coneofsilence"})
    assert response.status_code == 404
    assert response.json() == {"detail": "Item not found"}


def test_create_item():
    response = client.post(
        "/items/",
        headers={"X-Token": "coneofsilence"},

def test_read_nonexistent_item():
    response = client.get("/items/baz", headers={"X-Token": "coneofsilence"})
    assert response.status_code == 404
    assert response.json() == {"detail": "Item not found"}


def test_create_item():
    response = client.post(
        "/items/",
        headers={"X-Token": "coneofsilence"},

    /**
     * Generate the access token.
     * @return The access token.
     */
    public String generateAccessToken() {
        return RandomStringUtils.random(ComponentUtil.getFessConfig().getApiAccessTokenLengthAsInteger(), 0, 0, true, true, null, random);
    }

    /**
     * Get the access token from the request.
     * @param request The request.
     * @return The access token.
     */

    /**
     * Creates a Kerberos AP request from a token.
     *
     * @param token the Kerberos AP-REQ token
     * @param keys the Kerberos keys for decryption
     * @throws PACDecodingException if the token cannot be decoded
     */
    public KerberosApRequest(byte[] token, KerberosKey[] keys) throws PACDecodingException {
        this(parseSequence(token), keys);
    }

Наприклад, щоб оголосити заголовок `X-Token`, який може з’являтися більше ніж один раз:

{* ../../docs_src/header_params/tutorial003_an_py310.py hl[9] *}

Якщо Ви взаємодієте з цією операцією шляху, надсилаючи два HTTP-заголовки, наприклад:

```
X-Token: foo
X-Token: bar
```

Відповідь буде така:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

def test_parameterless_with_scopes():
    response = client.get(
        "/parameterless-with-scopes", headers={"authorization": "Bearer token"}
    )
    assert response.status_code == 200, response.text
