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.

get-file-upload-url
--assignment-id <value>
--question-identifier <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
--assignment-id
(string)
The ID of the assignment that contains the question with a FileUploadAnswer.
--question-identifier
(string)
The identifier of the question with a FileUploadAnswer, as specified in the QuestionForm of the HIT.
--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.
See ‘aws help’ for descriptions of global parameters.
FileUploadURL -> (string)
A temporary URL for the file that the Worker uploaded for the answer.
