Flask File Lister and Content Retriever

This Flask application provides an API to recursively list files in a directory and retrieve the content of specific files. It includes two main routes: one for listing files and directories and another for fetching the content of a file.

Features

• Recursively list files and directories starting from a root directory.
• Retrieve the content of a file through an API request.

Requirements

• Python 3.x
• Flask

Installation

1. Clone the repository or download the files.

2. Make sure you have Flask installed. You can install it using pip:

   pip install Flask

3. Run the Flask application:

   python app.py

API Endpoints

1. GET /

Lists all files and directories recursively starting from /home/ubuntu/.

Response:

• Success: Returns a list of dictionaries, each containing the filetype (either dir or file) and path.

  Example:

  [
      {"filetype": "dir", "path": "/home/ubuntu/some_folder"},
      {"filetype": "file", "path": "/home/ubuntu/some_folder/file.txt"}
  ]

2. POST /getfilecontent

Fetches the content of a specific file based on the provided file path.

Request:

• Content-Type: application/json
• JSON Body:

  {
      "path": "/path/to/file"
  }

Response:

• Success: Sends the file as a response for download.

• Error: If the file path is a directory or the file path is invalid, it returns an error message.

  Example error response:

  {
      "error": "filetype is directory"
  }

  {
      "error": "Invalid file Path"
  }

Running the Application

Once the server is running, you can use tools like curl, Postman, or any HTTP client to interact with the API:

Example request to list files:

curl http://localhost:4000/
