FILE STORAGES

Thinger.io provides a flexible cloud storage system that allows uploading files to the IoT server in order to provide support to other platform features, such as the HTML Widget or the OTA System. The information will be stored in a non-volatile memory of the server host.

Note that this feature is only available for private instances, as it requires a cloud storage system.

File Storages

File Storages provide a flexible file management system for storing and serving files within the platform. You can use storages for hosting static websites, storing firmware files, managing custom assets, exporting data, and more.

To manage your storages, navigate to Storages in the console.

Creating a Storage

Click Add Storage to create a new storage. The configuration includes:

Basic Information

• Storage ID: A unique identifier for the storage (alphanumeric and underscores, max 25 characters). This ID is used in URLs and API calls.

• Storage Name: A display name for the storage.

• Storage Description: Optional description for administrative purposes (max 255 characters).

Access Configuration

• Public Read: Enable to allow public access to files without authentication. When disabled, all file access requires authentication or a valid access token.

• Index File: The default file served when accessing the storage root URL (e.g., index.html). Useful for hosting static websites.

Terminal Configuration

• Terminal Image: A Docker image to use for the integrated terminal environment (e.g., alpine:latest, python:3.12-alpine). This allows running shell commands directly within the storage context.

HTTP Access

Once created, your storage is accessible via HTTP at:

https://your-platform.com/v2/users/{username}/storages/{storage_id}/files/

For public storages, files can be accessed directly without authentication. For private storages, include an authorization header or access token.

Integration Examples

File Storages can be accessed programmatically via the REST API, enabling integration with external systems, scripts, and devices. All examples use the v2 API endpoints.

Authentication

All requests to private storages require a Bearer token:

Authorization: Bearer YOUR_ACCESS_TOKEN

Public storages (with Public Read enabled) allow GET requests without authentication.

Listing Files

List contents of a directory:

curl -H "Authorization: Bearer YOUR_TOKEN" \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/"

List including hidden files:

curl -H "Authorization: Bearer YOUR_TOKEN" \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/?hidden=true"

List recursively (all subdirectories):

curl -H "Authorization: Bearer YOUR_TOKEN" \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/?recursive=true"

Downloading Files

Download a file:

curl -H "Authorization: Bearer YOUR_TOKEN" \
  -o firmware.bin \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/firmware/v1.0.0/firmware.bin"

For public storages, no authorization is needed:

curl -o firmware.bin \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/firmware/v1.0.0/firmware.bin"

Uploading Files

Upload a binary file (e.g., firmware):

  --data-binary @large_file.zip \
  --progress-bar \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/backups/large_file.zip"

Creating Directories

Create a directory (note the trailing slash):

curl -X PUT \
  -H "Authorization: Bearer YOUR_TOKEN" \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/new_folder/"

Create nested directories:

curl -X PUT \
  -H "Authorization: Bearer YOUR_TOKEN" \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/path/to/nested/folder/"

Deleting Files

Delete a file:

curl -X DELETE \
  -H "Authorization: Bearer YOUR_TOKEN" \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/old_file.txt"

Delete a directory and its contents:

curl -X DELETE \
  -H "Authorization: Bearer YOUR_TOKEN" \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/old_folder?recursive=true"

Renaming and Moving Files

Rename a file:

curl -X PATCH \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"path": "/new_name.txt"}' \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/old_name.txt"

Move a file to a different directory:

curl -X PATCH \
  -H "Authorization: Bearer YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"path": "/archive/2024/report.pdf"}' \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/report.pdf"

Getting File Information

Get metadata about a file without downloading it:

curl -H "Authorization: Bearer YOUR_TOKEN" \
  "https://iot.thinger.io/v2/users/USERNAME/storages/STORAGE_ID/files/firmware.bin?info=true"

Response:

{
  "name": "firmware.bin",
  "path": "/firmware.bin",
  "type": "file",
  "size": 524288,
  "modified": 1707123456
}

Device Integration Example

A typical IoT device firmware update flow:

# 1. Check for new firmware version
LATEST=$(curl -s "https://iot.thinger.io/v2/users/USERNAME/storages/firmware/files/latest.txt")

# 2. Download firmware if newer
curl -o /tmp/firmware.bin \
  "https://iot.thinger.io/v2/users/USERNAME/storages/firmware/files/releases/${LATEST}/firmware.bin"

# 3. Verify and apply update
# ... device-specific update logic

Access Control

Permissions

File Storages use fine-grained permissions:

Permission	Description
ReadStorageFiles	List, read, and download files
UpdateStorageFiles	Upload files and create directories
DeleteStorageFiles	Delete files and directories
RenameStorageFiles	Rename and move files
AccessStorageTerminal	Access the integrated terminal

Access Tokens

Create access tokens with limited permissions for external access:

1. Navigate to the storage settings

2. Create an access token with specific permissions (e.g., read-only)

3. Use the token in API requests or share for limited access

This is useful for:

• Providing read-only access to firmware downloads

• Allowing external services to upload files

• Sharing files without exposing full account credentials

---

Best Practices

1. Use descriptive storage IDs - Choose meaningful names like firmware, website, exports rather than generic names

2. Organize with directories - Structure files in logical folders for easier management

3. Set appropriate access levels - Only enable public read when necessary

4. Use access tokens - Create scoped tokens instead of sharing account credentials

5. Configure index files - For web-accessible storages, set an index file for cleaner URLs

6. Monitor storage usage - Keep track of storage consumption, especially for large files
