These are the same concept as request headers.

The headers allow the server to respond with additional metadata about the request.

The status message provides a human-readable message that helps describe the status code.

The status code indicates whether a request was completed successfully.

The version identifies the HTTP version, which will typically be the same as the request’s version.

The HTTP response contains the following elements: The server responds with an HTTP response. These are the tools your browser uses to communicate with a server. Though this field is not required, it’s typical for some methods to have a body, like a POST. The body provides the server with information from the client.The headers help describe additional information for the server.The version is one of several HTTP versions, like 1.0, 1.1, or 2.0.For example, the path of this page is /python-https. The path indicates to the server what web page you would like to request.The method for static content is typically GET, though there are others available, like POST, HEAD, and DELETE. The method describes what action the client wants to perform.HTTP requests contain the following elements: This is done with an HTTP request and response. It was designed to send content over the Internet, like HTML, videos, images, and so on. If you need a refresher, then check out Socket Programming in Python (Guide).Īs protocols go, HTTP is one of the simpler ones. In practice, this is almost always TCP over IP (though Google is trying to create a replacement). While HTTP doesn’t require TCP, it does require a reliable lower-level protocol. You make a request to a server, and the server returns a response. This breakdown captures the basics of HTTP. Your computer receives, parses, and displays the response.The server responds with an HTTP response.The server receives the HTTP request and parses it.Your browser sends an HTTP request to the server.Your device and the server set up a TCP connection.This diagram shows a simplified version of how your computer communicates with a server. Here’s a simplified diagram of HTTP communications: More specifically, HTTP is how a user agent, like your web browser, communicates with a web server, like. This acronym stands for HyperText Transfer Protocol, which underpins most of the communications that go on when you’re surfing your favorite websites. What Is HTTP?īefore you dive into HTTPS and its use in Python, it’s important to understand its parent, HTTP.
