Auth Plugin Library

Auth Plugin is a robust and flexible Python library designed to streamline the authentication process in web applications. It provides built-in support for JWT authentication, OAuth2 token management, and seamless database connectivity with MongoDB, PostgreSQL, and MySQL.

Features

• JWT Authentication: Easily encode and decode JSON Web Tokens (JWTs) with built-in error handling and robust security.
• OAuth2 Integration: Fetch and manage OAuth2 tokens with automatic error handling for HTTP requests and support for various grant types.
• Database Connectivity: Connect to MongoDB, PostgreSQL, and MySQL databases with a simple API and proper connection management.
• Robust Error Handling: Comprehensive try-except blocks across all operations, ensuring stability and reliability.
• Configurable Logging: Detailed logging for all operations, including JWT processing, OAuth2 token management, and database connections.

Installation

To install the Auth Plugin library, use pip:

pip install auth-plugin

Usage

JWT Authentication

The JWT authentication module allows you to encode and decode JSON Web Tokens.

from auth_plugin.jwt_auth import JWTAuth

# Initialize the JWTAuth object with a secret key
jwt_auth = JWTAuth(secret_key="your_secret_key")

# Encode a payload to generate a JWT token
token = jwt_auth.encode_token({"user_id": 123})

# Decode the JWT token to retrieve the payload
payload = jwt_auth.decode_token(token)

Database Management

The DBManager class supports connections to MongoDB, PostgreSQL and MySQL. Use the appropriate database type when initializing the object.

MongoDB

from auth_plugin.db_manager import DBManager

db_manager = DBManager(
    db_type="mongodb",  # or "mongo"
    host="localhost",
    port=27017,
    db_name="testdb"
)

PostgreSQL

db_manager = DBManager(
    db_type="postgres",
    user="username",
    password="password",
    host="localhost",
    port=5432,
    db_name="testdb"
)

MySQL

db_manager = DBManager(
    db_type="mysql",
    user="username",
    password="password",
    host="localhost",
    db_name="testdb"
)

Query Execution for All Supported Databases

The DBManager class provides methods for executing queries and fetching results. The behavior is different depending on whether you're using an SQL database (PostgreSQL, MySQL, SQLite) or a NoSQL database like MongoDB.

SQL Databases (PostgreSQL, MySQL)

For SQL-based databases (PostgreSQL and MySQL), you can execute SQL queries and fetch results using the following methods:

# Execute a query (e.g., creating a table)
db_manager.execute_query("CREATE TABLE IF NOT EXISTS users (id SERIAL PRIMARY KEY, name VARCHAR(255))")

# Insert data into the table
db_manager.execute_query("INSERT INTO users (name) VALUES (%s)", ("John Doe",))

# Fetch all results from a table
db_manager.execute_query("SELECT * FROM users")
results = db_manager.fetch_results()
print(results)

MongoDB

For MongoDB, you can interact with collections using the get_collection method, and perform operations like inserting or querying documents.

# Get a collection
collection = db_manager.get_collection("users")

# Insert a document into the collection
collection.insert_one({"name": "John Doe"})

# Query documents from the collection
results = collection.find({"name": "John Doe"})
for doc in results:
    print(doc)

Closing the Connection

After executing queries or performing operations, don't forget to close the connection.

db_manager.close()

OAuth2 Authentication

The OAuth2 authentication module allows you to obtain access tokens using the OAuth2 protocol.

from auth_plugin.oauth2_auth import OAuth2Auth

# Initialize the OAuth2Auth object with client credentials and token URL
oauth2 = OAuth2Auth(
    client_id="your_client_id",
    client_secret="your_client_secret",
    redirect_uri="http://localhost/callback",
    auth_url="https://example.com/oauth2/authorize",
    token_url="https://example.com/oauth2/token"
)

# Generate the authorization URL
authorization_url = oauth2.get_authorization_url()

# Exchange the authorization code for an access token
access_token = oauth2.get_access_token(code="authorization_code")
