0x01 Preface

During work, it is often necessary to communicate between servers or between processes and assign tasks. Using a Socket is too troublesome. You need to establish a connection to process messages. So

Prepare to create a Socket to simulate the help class of the Http server and call it directly through WebClient.

0x02 Http protocol

My understanding: the http protocol is actually based on a TCP/IP protocol. It can also send messages through socket, just to say. If the format of the sent content meets the http conditions, it can be understood as the http protocol.

Common Http headers. The Http Version can also be 1.1.

HTTP/1.0 200 OKContent-Type: text/htmlConnection: keep-aliveContent-Encoding: utf-8

0x03 TCP/IP

My understanding: the TCP/IP protocol is actually a big classification of a certain type of protocol. Many protocols transmit messages based on this protocol. Search for more details.

Because each time you write data from a Socket, you can only find it when you write more. In the past, you need to write a public class, which is not time-consuming.
