Software features

Resume upload from breakpoint
When uploading large files or uploading files on mobile devices, if the upload fails due to network quality, long transmission time, etc., you can use breakpoint resuming. In particular, preprocessing is not supported for images uploaded through resumed upload. In particular, files uploaded by resumable upload cannot be overwritten by other upload methods. If overwriting is needed, the file must be deleted first.
name concept
File chunking: directly split binary files into small chunks. Chunk size is fixed at 1M. Except for the last chunk.
Upload stage: Use the x-upyun-multi-stage parameter to indicate the stage of resumed upload. It is divided into the following three stages: initate (upload initialization), upload (uploading), complete (upload completed). Each stage is carried out in sequence.
Fragment serial number: Use the x-upyun-part-id parameter to indicate the current fragment serial number. The serial number starts from 0.
Sequential upload: For the same breakpoint resume upload task, only sequential upload is supported.
Upload identification: Use the x-upyun-multi-uuid parameter to uniquely identify an upload task. The type is a string and the length is 36 bits.
Upload cleaning: Unfinished files that have been uploaded after a breakpoint will be saved for 24 hours. After that, the files will be deleted.
