Exemplos de código para o SDK móvel do AWS WAF.

let url: URL = URL(string: "Web ACL integration URL")!
let configuration = WAFConfiguration(applicationIntegrationUrl: url, domainName: "Domain name")
let tokenProvider = WAFTokenProvider(configuration)

//onTokenReady can be add as an observer for UIApplication.willEnterForegroundNotification
self.tokenProvider.onTokenReady() { token, error in
	if let token = token {
	//token available
	}

	if let error = error {
	//error occurred after exhausting all retries
	}
}

//getToken()
let token = tokenProvider.getToken()

Exemplo de Java:

String applicationIntegrationURL = "Web ACL integration URL";
//Or
URL applicationIntegrationURL = new URL("Web ACL integration URL");

String domainName = "Domain name";

WAFConfiguration configuration = WAFConfiguration.builder().applicationIntegrationURL(applicationIntegrationURL).domainName(domainName).build();
WAFTokenProvider tokenProvider = new WAFTokenProvider(Application context, configuration);

// implement a token result callback
WAFTokenResultCallback callback = (wafToken, error) -> {
	if (wafToken != null) {
	// token available
	} else {  
	// error occurred in token refresh  
	}
};

// Add this callback to application creation or activity creation where token will be used
tokenProvider.onTokenReady(callback);

// Once you have token in token result callback
// if background refresh is enabled you can call getToken() from same tokenprovider object
// if background refresh is disabled you can directly call getToken()(blocking call) for new token
WAFToken token = tokenProvider.getToken();

Exemplo de Kotlin:

import com.amazonaws.waf.mobilesdk.token.WAFConfiguration
import com.amazonaws.waf.mobilesdk.token.WAFTokenProvider

private lateinit var wafConfiguration: WAFConfiguration
private lateinit var wafTokenProvider: WAFTokenProvider

private val WAF_INTEGRATION_URL = "Web ACL integration URL"
private val WAF_DOMAIN_NAME = "Domain name"

fun initWaf() {
	// Initialize the tokenprovider instance
	val applicationIntegrationURL = URL(WAF_INTEGRATION_URL)
	wafConfiguration =
		WAFConfiguration.builder().applicationIntegrationURL(applicationIntegrationURL)
			.domainName(WAF_DOMAIN_NAME).backgroundRefreshEnabled(true).build()
	wafTokenProvider = WAFTokenProvider(getApplication(), wafConfiguration)
	
		// getToken from tokenprovider object
		println("WAF: "+ wafTokenProvider.token.value)
	
		// implement callback for where token will be used
		wafTokenProvider.onTokenReady {
			wafToken, sdkError ->
		run {
			println("WAF Token:" + wafToken.value)
		}
	}
}

Quando setTokenCookie é TRUE, o provedor de token armazena o token do AWS WAF em um HTTPCookieStorage.shared e inclui automaticamente o cookie nas solicitações para o domínio que você especificou em WAFConfiguration.

let request = URLRequest(url: URL(string: domainEndpointUrl)!)
//The token cookie is set automatically as cookie header
let task = URLSession.shared.dataTask(with: request) { data, urlResponse, error  in
}.resume()

Quando setTokenCookie é TRUE, o provedor de token armazena o token do AWS WAF em uma instância CookieHandler que é compartilhada em todo o aplicativo. O provedor de token inclui automaticamente o cookie nas solicitações para o domínio que você especificou em WAFConfiguration.

Exemplo de Java:

URL url = new URL("Domain name");
//The token cookie is set automatically as cookie header
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.getResponseCode();

Exemplo de Kotlin:

val url = URL("Domain name")
//The token cookie is set automatically as cookie header
val connection = (url.openConnection() as HttpsURLConnection)
connection.responseCode

Se você já tiver a instância padrão CookieHandler inicializada, o provedor de token a usará para gerenciar cookies. Caso contrário, o provedor de token inicializará uma nova instância CookieManager com o token do AWS WAF CookiePolicy.ACCEPT_ORIGINAL_SERVER e, em seguida, definirá essa nova instância como a instância padrão em CookieHandler.

O código a seguir mostra como o SDK inicializa o gerenciador e o manipulador de cookies quando eles não estão disponíveis no seu aplicativo.

Exemplo de Java:

CookieManager cookieManager = (CookieManager) CookieHandler.getDefault();
if (cookieManager == null) {
	// Cookie manager is initialized with CookiePolicy.ACCEPT_ORIGINAL_SERVER
	cookieManager = new CookieManager();
	CookieHandler.setDefault(cookieManager);
}

Exemplo de Kotlin:

var cookieManager = CookieHandler.getDefault() as? CookieManager
if (cookieManager == null) {
	// Cookie manager is initialized with CookiePolicy.ACCEPT_ORIGINAL_SERVER
	cookieManager = CookieManager()
	CookieHandler.setDefault(cookieManager)
}

var request = URLRequest(url: wafProtectedEndpoint)
request.setValue("aws-waf-token=token from token provider", forHTTPHeaderField: "Cookie")
request.httpShouldHandleCookies = true
URLSession.shared.dataTask(with: request) { data, response, error in }

Exemplo de Java:

URL url = new URL("Domain name");
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
String wafTokenCookie = "aws-waf-token=token from token provider";
connection.setRequestProperty("Cookie", wafTokenCookie);
connection.getInputStream();

Exemplo de Kotlin:

val url = URL("Domain name")
val connection = (url.openConnection() as HttpsURLConnection)
val wafTokenCookie = "aws-waf-token=token from token provider"
connection.setRequestProperty("Cookie", wafTokenCookie)
connection.inputStream
