Postgres.app is a simple, native macOS app that runs in the menubar without the need of an installer. Open the app, and you have a PostgreSQL server ready and awaiting new connections. Close the app, and the server shuts down. PostgreSQL can also be installed on macOS using Homebrew. Please see the Homebrew documentation for.

The standard Python library has a built-in module that can be used as minimalistic HTTP/HTTPS web server. It providessupport of the protocol and allows you to extend capabilities by subclassing.

• How to download macOS Server. MacOS Server is available for $19.99 from the Mac App Store. As a former Linux/UNIX administrator used to configuring complicated text files via a terminal command line interface, that little cash for that much time-savings feels like a steal. You get all the UNIX underpinning with all the Mac accessibility.

Serve static HTML/CSS files to outside world can be very helpful and handy in many real life situations. For example,to show a client HTML pages you’ve created or stub an API by creating a static file.

Example of static HTTP web server

Yet another purpose that static web server can serve is to create a dummy API by creating json or/and xml files. The structure of resources organized in sub-folders will provide RESTful-like URLs. E.g. /users/all.json.json may contain dummy records of users. This approach even faster then creating, for instance, a Flask application. No database required, works everywhere.To download data from a remote server. Let’s say there are some difficulties with scp command. It is possible to run simple server on the remote machine and download necessary contents via HTTP.

Python 3.x

Both port and bind address are optional. For more details, please read theofficial docs.

Python 2.x

Python 2.x can only accept port as a parameter Bind address parameter is not available.Python 2.x Docs.

In both cases contents of the current folder will be accessible via http://127.0.0.1:8000

Example with SSL support

To run secure HTTPs server create a following module:

Python 3.x

Python 2.x

To generate key and cert files with OpenSSL use following command

Further examples will assume Python 3.5+ as an interpreter.

Advanced Python HTTP server

Let’s make our web server a little more advanced by handling requests.

do_GET

Consider the following code:

This is a very trivial HTTP server that responds Hello, world! to the requester. Note, that self.send_response(200) and self.end_headers() are mandatory, otherwise the response wont be consideredas valid. We can check that it actually works by sending a request using HTTPie:

Note, that self.wfile is a file like object, thus expects a byte-like objects to the write function.Another way of feeding the wfile is by using BytesIOobject (see example below).

do_POST

Let’s handle a POST request now. Full example:

The request body can be accessed via self.rfile. It is a BufferedReaderso read([size]) method should be executed in order to get the contents. Note, that size should beexplicitly passed to the function, otherwise the request will hang and never end.

This is why obtaining content_length is necessary. It could be retrieved via self.headers and convertedinto an integer. An example above just prints back whatever he receives, like follows:

You may consider to parse the JSON if you like.

Twisted As A Simple Web HTTP(S) Server

Another great example of a web server is Twisted. Clearly, it is much faster than one built in Python and provides lots of features out of the box. It supports SSL without a need to write a single line of code. It supports both Python 3.x and 2.x.

Installation

Usage

To run a twisted as a web server to serve current directory:

You will see the output like follows:

Options

-n, –nodaemon don’t daemonize, don’t use default umask of 0077

-o, –no_save do not save state on shutdown

Java Simple Https Server

–path= is either a specific file or a directory to be set as the root of the web server. Use this if you have adirectory full of HTML, cgi, epy, or rpy files or any other files that you want to be

Commands

web A general-purpose web server which can serve from a filesystem or application resource.

If you are looking for HTTPS and SSL support, consider the following options:

–https= Port to listen on for Secure HTTP.

-c, –certificate= SSL certificate to use for HTTPS. [default: server.pem]

-k, –privkey= SSL certificate to use for HTTPS. [default: server.pem]

Docker Example

Here are an example of Dockerfile I use to serve simple html pages to outside world.

Mac Web Server

It is possible to write custom handlers and extend the basic functionality. Including creating HTTPS server etc. Find official documentation for python 3 http server is here. Python 2 documentation is here
