What is in the Http Header?

The author has developed a simple, stable, and scalable delayed message queue framework for high-concurrency scenarios. It has precise timed tasks and delayed queue processing functions. Since it was open sourced for more than half a year, it has successfully provided precise timed scheduling solutions for more than a dozen small and medium-sized enterprises and has withstood the test of production environments. In order to benefit more friends, the open source framework address is now provided: https://github.com/sunshinelyz/mykit-delay

Preface

In the Internet era, the Http protocol is widely used. I believe that you are familiar with the Http protocol. Yes, most of the interfaces you write are Http interfaces, and most of the data exchanges between the front-end and the back-end are also through the Http protocol. Have you ever thought about what the message header contains in the Http protocol, in addition to the message body that we often use to transmit data? Today, Binghe will take you to find out.

HTTP protocol

HTTP (HyperTextTransferProtocol) is the Hypertext Transfer Protocol, the current universal protocol for web page transmission. The HTTP protocol adopts a request/response model, where the browser or other client sends a request and the server responds. As far as the entire network resource transmission is concerned, it includes two parts: message-header and message-body. First, the message-header is transmitted, that is, the http header message**. The http header message is usually divided into 4 parts: general header, request header, response header, entity header. However, this division feels unclear in terms of understanding. According to Wikipedia's organization of the http header content, it is generally divided into two parts: Request and Response.

Header Parameter Description

After working hard for most of the night, Binghe compiled the following description of Header parameters, hoping that it can bring substantial help to my friends.

The following table summarizes the header examples.

My liver is not moving anymore and my eyes are too sleepy to open. I'm going to sleep first. I suggest my friends to save this article first and read it later.
