# Simple OAuth2 with Password and Bearer { #simple-oauth2-with-password-and-bearer }

Now let's build from the previous chapter and add the missing parts to have a complete security flow.

## Get the `username` and `password` { #get-the-username-and-password }

We are going to use **FastAPI** security utilities to get the `username` and `password`.

    public OneSizeTestContainerGenerator<Map<K, V>, Entry<K, V>> getInnerGenerator() {
      return mapGenerator;
    }
  }

  // TODO: investigate some API changes to SampleElements that would tidy up
  // parts of the following classes.

  static <K extends @Nullable Object, V extends @Nullable Object>
      TestSetGenerator<K> keySetGenerator(
          OneSizeTestContainerGenerator<Map<K, V>, Entry<K, V>> mapGenerator) {

## Context

Modern best practices when developing a Gradle plugin are to use lazy types (ConfigurableFileCollection, Provider API, domain object containers) when defining configurable parts of a plugin (tasks, extensions, domain objects).  The Provider API provides a consistent way to set conventions, wire related configuration together (extension <- domain object <- task) and avoid evaluation ordering problems.

## Requirements

FastAPI stands on the shoulders of giants:

* [Starlette](https://www.starlette.dev/) for the web parts.
* [Pydantic](https://docs.pydantic.dev/) for the data parts.

## Installation

Create and activate a [virtual environment](https://fastapi.tiangolo.com/virtual-environments/) and then install FastAPI:

<div class="termy">

```console

        if (hostname != null && hostname.contains(".")) {
            // Extract potential cluster name from hostname
            String[] parts = hostname.split("\\.");
            if (parts.length > 1) {
                return parts[0]; // Use first part as cluster name
            }
        }
        return null;
    }

    /**
     * Register for witness notifications for a share

    }

    when {
      secondSpace != -1 && firstSpace == CLEAN.length && line.startsWith(CLEAN) -> {
        val parts =
          line
            .substring(secondSpace + 1)
            .split(' ')
        entry.readable = true
        entry.currentEditor = null
        entry.setLengths(parts)
      }

      secondSpace == -1 && firstSpace == DIRTY.length && line.startsWith(DIRTY) -> {

import java.util.regex.Matcher;
