How to send a HTTP request with client certificate + private key + password/secret in Python 3

When we need to create a HTTP client that communicates with a HTTP server through certificate-based authentication, we will typically have to download a certificate, in .pem format, from the server.

After we had downloaded the .pem file, the HTTP client will use the private key and certificate to authenticate itself with the HTTP server. Sometimes, the HTTP client will need to decrypt the private key with a password/secret first.

So with a .pem file and a password/secret, how can you create a HTTP client in Python 3 to send a HTTP request to the HTTP server?

In case you need it, this post shows how to send a HTTP request with client certificate + private key + password/secret in Python 3.

How to download a file via HTTP GET and HTTP POST in Java without using any external libraries

Apart from uploading a file to a HTTP server endpoint, another common task for a Java HTTP client is to download a file from a HTTP server. Even though there are many Java external libraries to help us do so, using the facilities in the Java standard runtime installation is not difficult. Furthermore, we will be able to keep our Java application leaner if we can download files without additional dependencies.

In case you need a reference, this is how to download a file via HTTP GET and HTTP POST in Java without using any external libraries.

How to send an HTTP request to a HTTP Basic Authentication endpoint in Python 3 with requests library

When you are building a Python 3 application for the Internet, you could encounter API endpoints that use HTTP Basic Authentication as the authentication mechanism.

In such a situation, using the requests library in your Python 3 code makes it easier to communicate with those endpoints.

In case you need to build a Python 3 application that sends HTTP request to a HTTP Basic Authentication endpoint, this is how you can do so with the requests library.

How to download a file via HTTP POST and HTTP GET with Python 3 requests library

When you are building a HTTP client with Python 3, you could be coding it to upload a file to a HTTP server or download a file from a HTTP server.

Previously, we discussed how to upload a file and some data through HTTP multipart in Python 3 using the requests library. In this post, let’s see how we can download a file via HTTP POST and HTTP GET.

Why Namecheap is the best domain name registrar for hosting your web server at home

Basically, a HTTP client contacts a HTTP server with an IP address. For example, when you access google.com, your web browser could be using 74.125.24.100 as the IP address to contact one of Google’s web servers. Although an IP address is what HTTP clients used for contacting HTTP servers, a domain name is easier to remember.

So if you want to host a web server at home, it is recommended that you get a domain name to make accessing your web server easier. In case you are looking for a domain name registrar to purchase a domain for your home server, this post discusses why you may want to buy from Namecheap.

Configuring Nginx and PHP 7 stack in Linux to increase or decrease file upload size limit

PHP web applications can utilize Nginx as the reverse proxy server and PHP FPM as the upstream server. Whenever you encounter HTTP file upload issues, limitation in file upload size is one common cause.

This post shows how to adjust the file upload size limit for your application running on a Nginx-PHP stack in Linux.

With this purpose in mind, this post discusses how to send a HTTP GET request to an API endpoint and add the response as HTML elements to the DOM with jQuery.

How to setup Codiad Web IDE on your Raspberry Pi 3 with Raspbian Stretch Lite, Nginx and PHP

A Web IDE server allows you to code wherever you are and whenever you want from any device through a web browser. A Raspberry Pi 3 board is a good gift for programmers and if you happen to receive one or bought one and do not know what to do with it, you may want to setup Codiad Web IDE on it to help you code while you are on the move.

Read on to find out how to setup Codiad Web IDE on your Raspberry Pi 3 with Raspbian Stretch Lite, Nginx and PHP as the LEMP stack.

Configuring Nginx for PHP web applications

Nginx and PHP FastCGI Process Manager (FPM) are often used side by side for PHP applications. In such a setting, Nginx will be the first point of contact for incoming HTTP requests, acting as a reverse proxy server for the PHP FastCGI Process Manager.

The PHP FastCGI Process Manager then interprets the HTTP requests that it receives from Nginx and runs the PHP scripts for generating the corresponding HTTP responses for Nginx to return back to the HTTP client.

This post discusses a set of configurations that you can use for configuring Nginx for your PHP web applications.
