// The GetFileUploadURL 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 FileUploadAnswer 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.
