Asset Bank API

Summary

This is a step by step guide to uploading a large file by breaking the file into chunks and submitting each chunk separately.

Steps

1. get api URLs
2. create new chunked file
3. upload chunks
4. create asset
5. update asset bank with file from uploaded chunks

Get API URL

It is recommended to code against the API using the following root request to look up the URLs rather than hard code the urls directly as this will ensure that new versions of the API do not introduce incompatibility issues.

For example, from the response JSON structure, select the version of the API and look up the URL for the API resource (e.g. api_version_1_3.tempChunkedFileUrl).

Request

curl -X GET -H "Accept: application/json" "http://127.0.0.1:8080/asset-bank/rest/"
