Não é como se fosse uma chave permanente que vai funcionar para sempre (na maioria dos casos). + * O frontend armazena aquele token temporariamente em algum lugar. + * O usuário clica no frontend para ir à outra seção daquele frontend do aplicativo web. + * O frontend precisa buscar mais dados daquela API. + * Mas precisa de autenticação para aquele endpoint em específico. + * Então, para autenticar com nossa API, ele manda um header de `Autorização` com o valor `Bearer` mais o token. + * Se o token contém `foobar`, o conteúdo do header de `Autorização` será: `Bearer foobar`. + +## **FastAPI**'s `OAuth2PasswordBearer` + +**FastAPI** fornece várias ferramentas, em diferentes níveis de abstração, para implementar esses recursos de segurança. + +Neste exemplo, nós vamos usar o **OAuth2** com o fluxo de **Senha**, usando um token **Bearer**. Fazemos isso usando a classe `OAuth2PasswordBearer`. + +!!! informação + Um token "bearer" não é a única opção. + + Mas é a melhor no nosso caso. + + E talvez seja a melhor para a maioria dos casos, a não ser que você seja um especialista em OAuth2 e saiba exatamente o porquê de existir outras opções que se adequam melhor às suas necessidades. + + Nesse caso, **FastAPI** também fornece as ferramentas para construir. + +Quando nós criamos uma instância da classe `OAuth2PasswordBearer`, nós passamos pelo parâmetro `tokenUrl` Esse parâmetro contém a URL que o client (o frontend rodando no browser do usuário) vai usar para mandar o `username` e `senha` para obter um token. + +```Python hl_lines="6" +{!../../../docs_src/security/tutorial001.py!} +``` + +!!! dica + Esse `tokenUrl="token"` se refere a uma URL relativa que nós não criamos ainda. Como é uma URL relativa, é equivalente a `./token`. + + Porque estamos usando uma URL relativa, se sua API estava localizada em `https://example.com/`, então irá referir-se à `https://example.com/token`. Mas se sua API estava localizada em `https://example.com/api/v1/`, então irá referir-se à `https://example.com/api/v1/token`. + + Usar uma URL relativa é importante para garantir que sua aplicação continue funcionando, mesmo em um uso avançado tipo [Atrás de um Proxy](../../advanced/behind-a-proxy.md){.internal-link target=_blank}. + +Esse parâmetro não cria um endpoint / *path operation*, mas declara que a URL `/token` vai ser aquela que o client deve usar para obter o token.
