To get a pre-signed S3 upload URL for course materials, use qingjiao_s3 with action set to "get_put_url" and business_type "upload_course_make_ppt" to validate inputs and return the URL for HTTP PUT uploads.
A pre-signed URL is a secure, one-time upload entry point for S3 storage. You need it when uploading PPTs or videos to the 青椒 platform, enabling direct HTTP PUT uploads without exposing your underlying S3 credentials.
You can upload video files to S3 storage using a pre-signed URL obtained via qingjiao_s3. The URL enforces security controls like size constraints and validity periods, and you transfer the file using a standard HTTP PUT request.
To upload PPTs to the 青椒 platform, first fetch the pre-signed URL via qingjiao_s3, then perform an HTTP PUT request targeting that URL with your file attached as the payload to complete the S3 upload.
S3 pre-signed upload URLs obtained through qingjiao_s3 include security controls for validity periods and size constraints. These limitations ensure secure, controlled uploads of course materials to the 青椒 platform's S3 storage.
