Examples with PresigningRequest com.amazonaws.services.polly.internal.PresigningRequest used on opensource projects

Example 1 with PresigningRequest

use of com.amazonaws.services.polly.internal.PresigningRequest in project aws-sdk-android by aws-amplify.

the class AmazonPollyPresigningClient method getPresignedSynthesizeSpeechUrl.

/**
 * <p>
 * Returns a pre-signed URL for accessing an Amazon Polly resource.
 * </p>
 * <p>
 * Pre-signed URLs allow clients to form a URL for an Amazon Polly
 * resource, and then sign it with the current AWS security credentials.
 * The pre-signed URL can be shared to other users, allowing access to
 * the resource without providing an account's AWS security credentials.
 * </p>
 * <p>
 * Pre-signed URLs are useful in many situations where AWS security
 * credentials aren't available from the client that needs to make the
 * actual request to Amazon Polly.
 * </p>
 * <p>
 * For example, a pre-signed URL to GET the synthesized speech audio stream
 * using the owner's AWS account can be generated and passed to a system
 * media player.
 * </p>
 *
 * @param synthesizeSpeechPresignRequest Object providing pre-signed synthesize speech
 *              request parameters.
 * @return Pre-signed URL of audio stream containing synthesized speech
 *              matching parameters provided in synthesizeSpeechPresignRequest
 *              that is possible to obtain using HTTP GET method.
