`Although it is an article on Mac environment, the procedure is the same for Windows environment. Please read and try the environment-dependent part. ``
After reading this article to the end, you will be able to:
| No. | Overview | keyword |
|---|---|---|
| 1 | Signed URL generation | s3, generate_presigned_url |
| environment | Ver. |
|---|---|
| macOS Catalina | 10.15.3 |
| Python | 3.7.3 |
| boto3 | 1.11.17 |
I think that understanding will deepen if you read while actually following the implementation contents and source code. Please use it by all means.
