### Autentique-se { #authenticate }

Clique no botão "Authorize".

Use as credenciais:

User: `johndoe`

Password: `secret`

<img src="/img/tutorial/security/image04.png">

Após autenticar no sistema, você verá assim:

        ApiResult badRequestResult = new ApiResult.ApiResponse().status(Status.BAD_REQUEST).result();
        assertNotNull(badRequestResult);

        // Test UNAUTHORIZED status
        ApiResult unauthorizedResult = new ApiResult.ApiResponse().status(Status.UNAUTHORIZED).result();
        assertNotNull(unauthorizedResult);

        // Test FAILED status

    val response =
      Response
        .Builder()
        .request(request)
        .code(401)
        .header("WWW-Authenticate", "Basic realm=\"User Visible Realm\"")
        .protocol(HTTP_2)
        .message("Unauthorized")
        .build()
    val authRequest = authenticator.authenticate(route, response)

    assertEquals(
      "Basic ${RecordingAuthenticator.BASE_64_CREDENTIALS}",
      authRequest!!.header("Authorization"),

    public ApiResponse handleApplicationException(final ApiFailureResource resource, final RuntimeException cause) {
        if (cause instanceof LoginUnauthorizedException) {
            return asJson(createFailureBean(Status.UNAUTHORIZED, "Unauthorized request.")).httpStatus(HTTP_UNAUTHORIZED);
        }
        return asJson(createFailureBean(Status.BAD_REQUEST, createMessage(resource, cause))).httpStatus(HTTP_BAD_REQUEST);
    }

  /** Guarded by this. */
  private OAuthSession session;

  public SlackClient(SlackApi slackApi) {
    this.slackApi = slackApi;
  }

  /** Shows a browser URL to authorize this app to act as this user. */
  public void requestOauthSession(String scopes, String team) throws Exception {
    if (sessionFactory == null) {
      sessionFactory = new OAuthSessionFactory(slackApi);

OPA is a lightweight general-purpose policy engine that can be co-located with MinIO server, in this document we talk about how to use OPA HTTP API to authorize requests. It can be used with any type of credentials (STS based like OpenID or LDAP, regular IAM users or service accounts).

OPA is enabled through MinIO's Access Management Plugin feature.

## Get started

  }

  /** See https://api.slack.com/docs/oauth. */
  public HttpUrl authorizeUrl(String scopes, HttpUrl redirectUrl, ByteString state, String team) {
    HttpUrl.Builder builder = baseUrl.newBuilder("/oauth/authorize")
        .addQueryParameter("client_id", clientId)
        .addQueryParameter("scope", scopes)
        .addQueryParameter("redirect_uri", redirectUrl.toString())
        .addQueryParameter("state", state.base64());

これが標準の利点です…。

### 認証 { #authenticate }

「Authorize」ボタンをクリックします。

次の認証情報を使います:

User: `johndoe`

Password: `secret`

<img src="/img/tutorial/security/image04.png">

システムで認証されると、次のように表示されます:

<img src="/img/tutorial/security/image05.png">

        // Full NTLM handshake testing would require more complex mocking

        // Arrange - Mock a server that supports NTLM
        mockResponse(HTTP_UNAUTHORIZED, "Unauthorized", Collections.singletonMap("WWW-Authenticate", Collections.singletonList("NTLM")),
                new ByteArrayInputStream(new byte[0]));

        // Act - Trigger handshake

{* ../../docs_src/security/tutorial005_an_py310.py hl[63:66] *}

Because we are now declaring those scopes, they will show up in the API docs when you log-in/authorize.

And you will be able to select which scopes you want to give access to: `me` and `items`.

This is the same mechanism used when you give permissions while logging in with Facebook, Google, GitHub, etc:
