Course Introduction：The English name of HTTP status code is HTTP Status Code. When a user browses a web page, the user's browser will send a request to the server where the web page is located, and before the browser receives the request, the web page's server will return an HTTP status code information. header in response to the browser's request. The following common HTTP status codes: 200-Request successful, 301-The resource (webpage, etc.) is permanently transferred to another URL, 404-The requested resource (webpage, etc.) does not exist, 500-Internal server error.

Course Introduction：HTTP protocol (HyperText Transfer Protocol, Hypertext Transfer Protocol) is a transfer protocol used to transfer hypertext from the WWW server to the local browser. It can make the browser more efficient and reduce network transmission. It not only ensures that the computer transmits hypertext documents correctly and quickly, but also determines which part of the document is transmitted and which part of the content is displayed first (such as text before graphics), etc. We have collected the "Boolean Educational HTTP Protocol Video Tutorial", hoping to help everyone better understand the HTTP protocol.

Course Introduction：Swoft is a high-performance PHP coroutine framework developed based on Swoole extension. It is lightweight, high-performance, flexible and scalable. This course will lead students to learn and master the use of the Swoft framework from scratch through a series of chapters. In the first chapter, we will learn how to create a basic HTTP API and introduce the simulation of commodity API and the use of RequestMapping annotations. In the next few chapters, we will learn how to create product lists, product detail pages, and use regular expressions to control routing path parameters. In Chapter 5, we will initially learn how to use middleware and modify the return value of the controller method. In Chapters 6, 7, and 8, we will learn how to obtain GET parameters and POST parameters, and simulate product modification operations. In Chapters 9, 10, and 11, we will learn how to automatically convert JSON parameters into entity objects and use reflection to execute setter functions. In Chapter 12, we will learn the basic configuration of the database and use native queries to obtain product details. In Chapters 13 and 14 we will learn how to use validators and practice controlling character length validation. In Chapter 15, we will learn more ways to use the validator, including validation types and non-annotation usage, and upgrade the Swoft version. Finally, in Chapter 16, we will learn about database connection pooling

Course Introduction：Hypertext Transfer Protocol (HTTP) is an application layer protocol for transmitting hypermedia documents. It is designed for communication between a web browser and a web server, but can be used for other purposes as well. HTTP follows the classic client-server model, where the client opens a connection to make a request and then waits until a server-side response is received.
Course Elementary 8311
Course Introduction：HTTP communicates based on B/S architecture, and the server-side implementation programs of HTTP include httpd, nginx, etc. The client-side implementation programs are mainly web browsers, such as Firefox, Google Chrome, Safari, etc. In addition, the client's command line Tools include elink, curl, etc. Web services are based on TCP, so in order to respond to client requests at any time, the Web server needs to listen on port 80/TCP. In this way, the client browser and the web server can communicate through HTTP.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
