Course Introduction:The HTTP protocol is a simple request-response protocol that usually runs on top of TCP. It specifies what kind of messages the client may send to the server and what kind of response it gets. The headers of request and response messages are given in ASCII form; the message contents have a MIME-like format.

Course Elementary 26430
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: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: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: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: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 Introduction:Go's syntax is close to C language, but the declaration of variables is different. Go supports garbage collection. Go's parallel computing model is based on Tony Hall's Communicating Sequential Process (CSP). Other languages that adopt similar models include Occam and Limbo. Go also has the characteristics of this model, such as channel transmission. Compared with C++, Go does not include functions such as enumeration, exception handling, inheritance, generics, assertions, virtual functions, etc., but it adds features such as slice type, concurrency, pipelines, garbage collection functions, interfaces, etc. level support. Unlike Java, Go natively provides associative arrays (also called hashes or dictionaries), just like string types.
