Flask AWS File Sharing Application

This is a Flask application for file sharing and emailing using AWS services. The application allows users to upload files to an AWS S3 bucket, share the file link via email, and generate a pre-signed URL for file access.

Prerequisites

Before running the application, make sure you have the following:

• Python installed on your machine.
• An AWS account with the necessary credentials and permissions set up.
• The required Python libraries installed (Flask, boto3, mysql-connector-python, requests).

Usage

1. Clone the repository and navigate to the project folder.

2. Install the required dependencies:

pip install Flask boto3 mysql-connector-python requests

3. Set up your AWS credentials:

   • Create a file named key.json with the following structure:

     {
       "access_key": "YOUR_AWS_ACCESS_KEY",
       "secret_key": "YOUR_AWS_SECRET_KEY",
       "bucket": "YOUR_S3_BUCKET_NAME"
     }

     Replace YOUR_AWS_ACCESS_KEY, YOUR_AWS_SECRET_KEY, and YOUR_S3_BUCKET_NAME with your AWS credentials and S3 bucket name.

4. Start the Flask server:

python app.py

5. The server will start running on http://localhost:5000.

6. Open your browser and navigate to http://localhost:5000 to access the application.

Routes

• GET /: Renders the index.html template.

• POST /submitForm: Handles user login form submission and checks the user's credentials against the database.

• POST /uploadFile: Uploads a file to the specified AWS S3 bucket.

• POST /sendemail: Sends emails with the file link to the specified recipients.

• GET /report: Renders the report.html template.

AWS Services Used

• Amazon S3: Used for file storage and retrieval.

• AWS Lambda and API Gateway: Used to trigger the email sending process via a serverless API endpoint.

Database

The application connects to a MySQL database running on the RDS instance with the following configuration:

• Host: cloudfinaldb.cl7uutdsqhvw.us-east-1.rds.amazonaws.com
• Port: 3306
• Username: admin
• Region: us-east-1c
• Database: clouddb

Ensure that you have the necessary database set up with the required user table.
