This is normally the best way to contribute to the project.

## External Contributions

External contributions are very welcome and appreciated, including answering questions, submitting PRs, etc. 🙇‍♂️

Vou mostrar alguns dos principais conceitos que você provavelmente deve ter em mente ao implantar uma aplicação **FastAPI** (embora a maior parte se aplique a qualquer outro tipo de aplicação web).

                    }
                }
            }
        } catch (IOException | XMLStreamException e) {
            // The root locator can be used very early during the setup of Maven,
            // even before the arguments from the command line are parsed.  Any exception
            // that would happen here should cause the build to fail at a later stage

## 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);

This is just a **quick tutorial / refresher** about Python type hints. It covers only the minimum necessary to use them with **FastAPI**... which is actually very little.

**FastAPI** is all based on these type hints, they give it many advantages and benefits.

But even if you never use **FastAPI**, you would benefit from learning a bit about them.

/// note

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 😉).
