c# - Uploading to Azure Media Services with sas url using rest api -

i followed guide https://azure.microsoft.com/en-us/documentation/articles/media-services-rest-upload-files/ , have gotten part have sas url (upload url). here im in doubt of im supposed do. followed link lead me azure storage services - whole other documentation specifying how authenticate requests , make canonicalized strings. have upload url - url created through many steps already. please tell me im supposed when have upload url , want upload media file? in advance, im kinda lost here.

if have sas url, need @ following rest api functions: put blob, put block , put block list.

when using these rest api operations, things consider:

• your request url sas url.
• since you're using sas url, don't worry authorization header authorization information included in sas token (sig query string parameter).
• you don't have include x-ms-version , x-ms-date headers well.
• don't forget include x-ms-blob-type header , make sure it's value blockblob.

in general, use put blob operation if file size smaller. larger files, split file in chunks (known blocks) , upload chunks using put block operation. once chunks completed, call put block list operation commit blob.
