This project serves as an API Gateway implemented in Python using Flask.

The API Gateway is responsible for routing incoming requests to the appropriate backend services, managing authentication and authorization, and aggregating the responses before sending them back to the client.

• Routing: Directs incoming requests to the appropriate backend service based on the request path.
• Authentication and Authorization: Implements authentication and authorization mechanisms to ensure secure access to backend services.
• Request Aggregation: Aggregates responses from multiple backend services and sends a single response back to the client.
• Logging: Records request and response information for monitoring and debugging purposes.

1. Clone the repository:

git clone https://github.com/majdrezik/api_gateway_python.git
cd api_gateway_python

3. Install dependencies:

  pip install -r requirements.txt

1. Run the main Flask application: (root directory)

flask run --host 172.31.255.1 --port 5000

3. Run the services:

   • cd services/{SERVICE_NAME_1}

   • flask run --host 192.168.1.195 --port 10030

   • cd services/{SERVICE_NAME_2}

   • flask run --host 192.168.1.195 --port 10031

Make sure you assing different ports to each service

On Postman navigate to http://127.0.0.1:5000 which acts as our Entrypoint (client) and choose different apis from the list (e.g http://127.0.0.1:5000/v1/echo) This will show the starting point and the end result (starting from one url and ending in another url). You can try accessing the micro-service directly, like http://192.168.1.195:10030/ . this will fail (made a simple firewall)
