## Forbid Extra Query Parameters { #forbid-extra-query-parameters }

In some special use cases (probably not very common), you might want to **restrict** the query parameters that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:

        final byte[] sk = this.verifyKey;
        if (sk == null) {
            throw new CIFSException("Signing is not initialized");
        }

        final int ver = SMBUtil.readInt4(mic, 0);
        if (ver != 1) {
            throw new SmbUnsupportedOperationException("Invalid signature version");
        }

        final MessageDigest mac = Crypto.getHMACT64(sk);

Because this code is executed before the application **starts** taking requests, and right after it **finishes** handling requests, it covers the whole application **lifespan** (the word "lifespan" will be important in a second 😉).

Você verá algo como:

```JSON
{"item_id": 5, "q": "somequery"}
```

* Add more granular permission controls with OAuth2 scopes where needed.

Nevertheless, you might have a very specific use case where you really need to disable the API docs for some environment (e.g. for production) or depending on configurations from environment variables.
