HTTPlex - a simple HTTP request & response service

HTTPlex is an Elixir-based web service that provides a simple HTTP request and response service. It is inspired from httpbin and helps developers test and debug HTTP requests.

Features

The project is built using Elixir and the Phoenix framework. It defines a controller (HTTPlexWeb.APIController) that handles various HTTP endpoints:

HTTP Methods:

• index/2: Welcome message
• get/2, post/2, put/2, patch/2, delete/2: Return request info for respective HTTP methods
• anything/2: Accepts and returns data for any HTTP method

Request Inspection:

• ip/2: Returns the client's IP address
• user_agent/2: Returns the user-agent header
• headers/2: Returns all request headers

Response Inspection:

• response_headers/2: Sets custom response headers

Auth:

• basic_auth/2, hidden_basic_auth/2: Test Basic Authentication (hidden version doesn't send WWW-Authenticate header)
• bearer/2: Tests Bearer Token Authentication
• digest_auth/2: Tests Digest Authentication

Status codes:

• status/2: Returns response with specified status code

Request formats:

• forms_post/2: Handles form data submission

Response formats:

• html_response/2: Returns an HTML response
• json_response/2: Returns a JSON response
• xml/2: Returns an XML response
• image/2: Returns an image in specified format

Redirects:

• absolute_redirect/2: Performs absolute redirects
• redirect_to/2: Redirects to specified URL
• redirectx/2: Performs multiple redirects
• relative_redirect/2: Performs relative redirects

Dynamic data:

• uuid/2: Generates and returns a UUID
• random_bytes/2: Returns random bytes
• deny/2: Simulates denied access by robots.txt
• robots_txt/2: Returns a sample robots.txt file
• delay/2: Delays the response for specified seconds
• drip/2: Drips data over a duration
• links/2: Returns page containing n links
• range/2: Streams n bytes with Accept-Ranges and Content-Range headers
• stream_bytes/2: Streams n bytes of data
• stream_json/2: Streams JSON data

Cookies:

• get_cookies/2: Returns all cookies sent with the request
• set_cookies/2, set_cookie/2: Set multiple or a single cookie
• delete_cookies/2: Deletes specified cookies

Encoding:

• brotli/2: Returns Brotli-encoded data
• deflate/2: Returns Deflate-encoded data
• gzip/2: Returns GZip-encoded data
• encoding_utf8/2: Returns UTF-8 encoded text

Caching:

• cache/2: Tests caching headers
• cache_control/2: Sets Cache-Control header with specified max-age
• etag/2: Tests ETag functionality

Each function or group of functions corresponds to different features or test scenarios for HTTP requests and responses.

Usage

To use HTTPlex, send HTTP requests to the appropriate endpoints. The service will respond with JSON data (in most cases) containing the requested information or performing the specified action.

For example:

• GET /ip will return your IP address.
• POST /post with some data will echo back information about your POST request.
• GET /status/404 will respond with a 404 status code.

This service is particularly useful for testing HTTP clients, debugging web applications, and understanding how different types of HTTP requests are structured and processed.

Running it

To start your Phoenix server:

• Run mix setup to install and setup dependencies
• Start Phoenix endpoint with mix phx.server or inside IEx with iex -S mix phx.server

Now you can visit localhost:4000 from your browser.

Ready to run in production? Please check Phoenix deployment guides.
