Golang HTTP Server Analysis (1)--Overview

Golang streamlined and intuitive design, allowing web development and writing print "Hello world" identical. It also gives me a chance to get a glimpse of the design and implementation of HTTP Server. So far, before Tomcat, Apache and other web containers gave me the mystique swept away.

1. Basic knowledge

The purpose of HTTP server is to implement HTTP Protocol, let's briefly describe the HTTP Protocol.

An HTTP message consists of a single line of simple strings. HTTP messages are plain text and are the carrier of web information transmission. The following is a simple scenario for representing the HTTP message format.

Host:localhost:8080/login

Accept:text/html

username=yasun&password=1234

The second step: the server returns the login information of the personal blog page information, send response message for

Step three: Users click on Blog 1, the browser sends a GET request
