    @DisplayName("writeSetupWireFormat writes subCommand and padding")
    void testWriteSetup() throws Exception {
        Trans2GetDfsReferral cmd = new Trans2GetDfsReferral("foo");
        byte[] buf = new byte[2];
        int r = cmd.writeSetupWireFormat(buf, 0);
        assertEquals(2, r);
        byte subCmd = (byte) getPrivateField(cmd, "subCommand");
        assertEquals(subCmd, buf[0]);

Das würde bedeuten, dass **FastAPI** einen Body wie folgt erwartet:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

Wiederum, nur mit dieser Deklaration erhalten Sie von **FastAPI**:

    publicSuffixList.ensureLoaded()

    // Break apart the domain into UTF-8 labels, i.e. foo.bar.com turns into [foo, bar, com].
    val domainLabelsUtf8Bytes = Array(domainLabels.size) { i -> domainLabels[i].encodeUtf8() }

    // Start by looking for exact matches. We start at the leftmost label. For example, foo.bar.com
    // will look like: [foo, bar, com], [bar, com], [com]. The longest matching rule wins.
    var exactMatch: String? = null

    }
    assertFailsWith<SSLPeerUnverifiedException> {
      certificatePinner.check("foo.bar.example.co.uk", listOf(certB1.certificate))
    }
    assertFailsWith<SSLPeerUnverifiedException> {
      certificatePinner.check("foo.bar.baz.example.co.uk", listOf(certB1.certificate))
    }

        ]
    }

Eğer bu *path operation* ile iki HTTP header göndererek iletişim kurarsanız:

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

response şöyle olur:

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

## Özet { #recap }

Header'ları `Header` ile tanımlayın; `Query`, `Path` ve `Cookie` ile kullanılan ortak kalıbı burada da kullanın.
