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.
