Flask Request Headers Printer
Overview
This repository contains a simple Python Flask application that listens for HTTP GET and POST requests and prints the request headers in an HTML format. The application is lightweight and designed to run within a Docker container, making it ideal for testing and debugging HTTP headers.
Flask Application Code
Below is the core Python Flask application code:
pythonfrom flask import Flask, request app = Flask(__name__) @app.route("/", methods=["GET", "POST"]) def print_headers(): headers = request.headers header_html = "<html><body><h1>Request Headers</h1><ul>" for header, value in headers.items(): header_html += f"<li><strong>{header}:</strong> {value}</li>" header_html += "</ul></body></html>" return header_html, 200 if __name__ == "__main__": app.run(host="0.0.0.0", port=80)
Features
- Request Header Display: The application captures HTTP request headers and renders them in a simple HTML list format.
- Supports GET and POST Methods: It listens for both GET and POST requests at the root endpoint (
/). - Lightweight and Easy to Use: Built with Flask, this app is easy to run and deploy, especially in containerized environments.
Usage
You can easily pull the image from Docker Hub and run it locally or in your cloud environment.
Steps to Run:
-
Pull the Docker image from Docker Hub:
bashdocker pull mejatos/request-headers -
Run the container:
bashdocker run -p 80:80 mejatos/request-headers -
Send a request to the application:
You can use
curl, Postman, or a web browser to send an HTTP request:bashcurl http://localhostThe response will be an HTML page that lists all the request headers received.
Example Response
After sending a request, the application will respond with an HTML page like this:
html<html> <body> <h1>Request Headers</h1> <ul> <li><strong>Host:</strong> localhost</li> <li><strong>User-Agent:</strong> curl/7.68.0</li> <li><strong>Accept:</strong> */*</li> </ul> </body> </html>
Building the Image Locally
If you'd like to build the Docker image yourself, use the following Dockerfile:
Dockerfile# Use official Python runtime as parent image FROM python:3.11-slim # Set the working directory in the container WORKDIR /app # Copy the current directory contents into the container COPY . /app # Install Flask RUN pip install Flask # Expose port 80 EXPOSE 80 # Run the application CMD ["python", "app.py"]
To build and run the image locally:
bashdocker build -t flask-request-headers-printer . docker run -p 80:80 flask-request-headers-printer
