How to access HTTP response headers after making an HTTP request with Apache HttpClient

This is an excerpt from the Scala Cookbook (partially modified for the internet). This is a very short recipe, Recipe 15.12, “How to access HTTP response headers after making an HTTP request with Apache HttpClient.”

Problem

You need to access the HTTP response headers after making an HTTP request in your Scala code.

Solution

Use the Apache HttpClient library, and get the headers from the HttpResponse object after making a request:

Get a web client's IP address with PHP

I just ran into a situation for a Drupal/PHP client where I wanted to log some access information. There was some unusual access activity on the website, and I want to log IP addresses and URLs for a few days.

As part of that, I wanted to get the web client's IP address, and in PHP you get the client IP address like this:

$ip = $_SERVER['REMOTE_ADDR'];

That returns something like this:

192.168.100.10

If you just need to get a web client's IP address from a PHP script, that's all you need.

A Scala JSON (Gson) HTTP POST RESTful client example

While working on a Scala project recently I created the following example Scala code to test a variety of things, including:

  • Scala case classes
  • The Apache HttpClient classes, including HttpPost
  • Creating JSON with Gson
  • Sending the JSON object/string to my POST RESTful server

Given that brief introduction, here's the source code for my Scala HTTP client, which uses POST (Apache HttpPost) to send data to a RESTful web service:
