Documentation

Use the following API to interact with the Object storage.

• To make changes (upload/delete/update) you will have to login, the login is implemented with JWT tokens.
• I have created 4 users upfront, can be found in users-logins.txt

API

Upload (Public)

POST /upload

Body: {files: […files]} // Add to the req.body files with key "files"

• Each file that is being uploaded, will get a secretId for private download later on.

---

Update

PATCH /update

Body: {fileName: YOUR_FILE_NAME}

• In case the file is not exist or you don’t have permissions you will get 404

• In case the file turned from public to private - an access token will be generated for you and you will get the object in return (don’t forget to copy it to download the file)

  ---

Download (Public)

GET /download || with queryparam: /filename

Body: { ownerId: ownerId }

• You will have to provide the ownerId of the file in the Body: { ownerId: ownerId }
• I assume that the OwnerId is given by user in the registration process (which I didn’t implement) With the Users I created, each one has an ownerId, if I want to download public file from user “Tomer” his ownerId is: jk12x9 so the link will be: s3IronSource.com/download?fileName=pizza.png with Body: {ownerId: jk12x9}

for Private Download we need to combine the file’s secretId that was generated during upload with the access_token, example:

s3IronSource.com/download/SECRET_FILE_ID?access_token=ACCESS_TOKEN

• to download file’s metadata: add "metadata=true" to query param

  ---

Delete

DELETE /delete

Body: {fileName: FILE_TO_DELETE}

Be sure you are logged in (brear token), provide in body the fileName for delete user is only able to deleted his own files
