## `username` und `password` entgegennehmen

Wir werden **FastAPIs** Sicherheits-Werkzeuge verwenden, um den `username` und das `password` entgegenzunehmen.

OAuth2 spezifiziert, dass der Client/Benutzer bei Verwendung des „Password Flow“ (den wir verwenden) die Felder `username` und `password` als Formulardaten senden muss.

    client =
      OkHttpClient.Builder()
        .proxy(server.toProxyAddress())
        .build()
    server.enqueue(MockResponse(body = "abc"))
    server.enqueue(MockResponse(body = "def"))
    server.enqueue(MockResponse(body = "ghi"))
    client = client.newBuilder().build()
    executeSynchronously("/a").assertBody("abc")
    client = client.newBuilder().build()

The spec also states that the `username` and `password` must be sent as form data (so, no JSON here).

### `scope`

The spec also says that the client can send another form field "`scope`".

The form field name is `scope` (in singular), but it is actually a long string with "scopes" separated by spaces.

  // The server returns only those CIDRs that it thinks that the client can match.
  // For example: the master will return an internal IP CIDR only, if the client reaches the server using an internal IP.
  // Server looks at X-Forwarded-For header or X-Real-Ip header or request.RemoteAddr (in that order) to get the client IP.
  repeated ServerAddressByClientCIDR serverAddressByClientCIDRs = 2;

    client.webSocket!!.finishReader()
    assertThat(client.closed).isTrue()
    client.listener.assertFailure(
      ProtocolException::class.java,
      "Server-sent frames must not be masked.",
    )
    server.listener.assertClosing(1000, "Hello")
    server.listener.assertExhausted() // Client should not have sent second close.
  }

They will be converted to their corresponding values (strings in this case) before returning them to the client:

```Python hl_lines="18  21  23"
{!../../docs_src/path_params/tutorial005.py!}
```

In your client you will get a JSON response like:

```JSON

  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```
