/**
 * <p>
 *             The
 *             <code>GetFileUploadURL</code>
 *             operation generates and returns a temporary URL. You use the
 *             temporary URL to retrieve a file uploaded by a Worker as an answer to
 *             a FileUploadAnswer question for a HIT. The temporary URL is generated
 *             the instant the GetFileUploadURL operation is called, and is valid
 *             for 60 seconds. You can get a temporary file upload URL any time
 *             until the HIT is disposed. After the HIT is disposed, any uploaded
 *             files are deleted, and cannot be retrieved.
 *
 *             Pending Deprecation on December 12, 2017. The Answer Specification
 *             structure will no longer  support the <code>FileUploadAnswer</code>
 *             element to be used for the QuestionForm data structure.
 *             Instead, we recommend that Requesters who want to create HITs asking
 *             Workers to upload files to use Amazon S3.
 *
 *         </p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { MTurkClient, GetFileUploadURLCommand } from "@aws-sdk/client-mturk"; // ES Modules import
 * // const { MTurkClient, GetFileUploadURLCommand } = require("@aws-sdk/client-mturk"); // CommonJS import
 * // import type { MTurkClientConfig } from "@aws-sdk/client-mturk";
 * const config = {}; // type is MTurkClientConfig
 * const client = new MTurkClient(config);
 * const input = { // GetFileUploadURLRequest
 *   AssignmentId: "STRING_VALUE", // required
 *   QuestionIdentifier: "STRING_VALUE", // required
 * };
 * const command = new GetFileUploadURLCommand(input);
 * const response = await client.send(command);
 * // { // GetFileUploadURLResponse
 * //   FileUploadURL: "STRING_VALUE",
 * // };
 *
 * ```
 *
 * @param GetFileUploadURLCommandInput - {@link GetFileUploadURLCommandInput}
 * @returns {@link GetFileUploadURLCommandOutput}
 * @see {@link GetFileUploadURLCommandInput} for command's `input` shape.
 * @see {@link GetFileUploadURLCommandOutput} for command's `response` shape.
 * @see {@link MTurkClientResolvedConfig | config} for MTurkClient's `config` shape.
 *
 * @throws {@link RequestError} (client fault)
 *  <p>Your request is invalid.</p>
 *
 * @throws {@link ServiceFault} (server fault)
 *  <p>Amazon Mechanical Turk is temporarily unable to process your request. Try your call again.</p>
 *
