View BLOB Management API Reference

Overview

The View BLOB (Binary Large Object) management system provides comprehensive storage and retrieval capabilities for unstructured data objects. BLOBs serve as flexible containers for various types of content including files, configurations, and binary data within the View platform.

Key Features

Flexible Storage: Store any type of binary or text data with automatic content type detection
Metadata Management: Rich metadata support including descriptions, references, and custom properties
Security Controls: Public/private access controls and tenant isolation
Data Integrity: Built-in hash verification (MD5, SHA1, SHA256) for data integrity
Reference System: Link BLOBs to other objects in the system for organized data management
Multi-format Support: Support for various content types and data formats

Supported Operations

Create: Upload new BLOB objects with metadata
Read: Retrieve BLOB metadata and data
Update: Modify existing BLOB properties and content
Delete: Remove BLOB objects from storage
Enumerate: List and search BLOB objects
Existence Check: Verify BLOB presence without downloading data

API Endpoints

BLOBs are managed via the Configuration server API at [http|https]://[hostname]:[port]/v1.0/tenants/[tenant-guid]/blobs

Supported HTTP Methods: GET, HEAD, PUT, DELETE

Response

Returns the updated BLOB object with metadata and hash values:

    "ContentType": "text/plain",
    "Name": "helloworld.txt",

}

Delete BLOB

Deletes a BLOB object by GUID using DELETE /v1.0/tenants/[tenant-guid]/blobs/[blob-guid]. This operation permanently removes the BLOB and its data from storage.

Request Parameters

blob-guid (string, Path, Required): GUID of the BLOB object to delete

curl --location --request DELETE 'http://view.homedns.org:8000/v1.0/tenants/00000000-0000-0000-0000-000000000000/blobs/00000000-0000-0000-0000-000000000000' \
--header 'Authorization: ••••••' \

import { ViewConfigurationSdk } from "view-sdk";

const api = new ViewConfigurationSdk(
  "http://localhost:8000/", //endpoint
  "default", //tenant Id
  "default" //access key
);
const deleteBlob = async () => {
  try {
    const response = await api.Blob.delete(
      "7f6eee35-fc32-4798-8ea7-e9e84775043e"
    );
    console.log(response, "Blob deleted successfully");
  } catch (err) {
    console.log("Error deleting Blob:", err);
  }
};

deleteBlob();

import view_sdk
from view_sdk import configuration

sdk = view_sdk.configure( access_key="default",base_url="localhost", tenant_guid= "00000000-0000-0000-0000-000000000000")

def deleteBlob():
    blob = configuration.Blob.delete("b1a953d8-2a51-496a-a272-52ebe326fd2d")
    print(blob)

deleteBlob()

using View.Sdk;
using View.Sdk.Configuration;

ViewConfigurationSdk sdk = new ViewConfigurationSdk(Guid.Parse("<tenant-guid>"),"default", "http://view.homedns.org:8000/");

bool deleted = await sdk.Blob.Delete(Guid.Parse("<blob-guid>"));

Response

Returns 200 No Content on successful deletion. No response body is returned.

Check BLOB Existence

Verifies if a BLOB object exists without downloading its content using HEAD /v1.0/tenants/[tenant-guid]/blobs/[blob-guid]. This is an efficient way to check BLOB presence before performing operations.

Request Parameters

blob-guid (string, Path, Required): GUID of the BLOB object to check

curl --location --head 'http://view.homedns.org:8000/v1.0/tenants/00000000-0000-0000-0000-000000000000/blobs/00000000-0000-0000-0000-000000000000' \
--header 'Authorization: ••••••'

import { ViewConfigurationSdk } from "view-sdk";

const api = new ViewConfigurationSdk(
  "http://localhost:8000/", //endpoint
  "default", //tenant Id
  "default" //access key
);

const blobExists = async () => {
  try {
    const response = await api.Blob.exists(
      "431638f9-1da1-4dd2-b6de-e88acf990c8c"
    );
    console.log(response, "Blob exists");
  } catch (err) {
    console.log("Error checking Blob:", err);
  }
};

blobExists();

import view_sdk
from view_sdk import configuration

sdk = view_sdk.configure( access_key="default",base_url="localhost", tenant_guid= "00000000-0000-0000-0000-000000000000")

def existsBlob():
    blob = configuration.Blob.exists("b1a953d8-2a51-496a-a272-52ebe326fd2d")
    print(blob)

existsBlob()

using View.Sdk;
using View.Sdk.Configuration;

ViewConfigurationSdk sdk = new ViewConfigurationSdk(Guid.Parse("<tenant-guid>"),"default", "http://localhost:8000/");

bool exists = await sdk.Blob.Exists(Guid.Parse("<blob-guid>"));

Response

200 No Content: BLOB exists
404 Not Found: BLOB does not exist
No response body: Only HTTP status code is returned

Note: HEAD requests do not return a response body, only the HTTP status code indicating whether the BLOB exists.

Best Practices

When working with BLOB objects in the View platform, consider the following recommendations:

Data Encoding: Always encode binary data as Base64 when uploading to ensure proper transmission
Content Types: Set appropriate MIME types for better content handling and validation
Data Integrity: Verify hash values (MD5, SHA1, SHA256) for critical data integrity checks
Efficient Operations: Use HEAD requests to check existence before downloading large BLOBs
Security: Be mindful of IsPublic settings and tenant isolation for sensitive data

Next Steps

After successfully managing BLOB objects, you can:

Integrate with Applications: Use BLOB data in your applications and workflows
Implement File Management: Build file upload/download interfaces using BLOB operations
Data Processing: Process BLOB content for analysis, transformation, or reporting
Content Delivery: Use BLOB URLs for content delivery in web applications
API Integration: Integrate BLOB operations with other View platform APIs
