Introduction: With the development of the Internet, live streaming on the Internet has become the darling of various new media platforms. If you are interested in the implementation principle of the "bullet chat" service in live streaming, please enter the course and follow the teacher's steps into his "main control room".
In this course, the teacher will lead you in sequence to analyze the technical difficulties of the bullet screen system, how to quickly master the protocol and interaction process of WebSocket, how to encapsulate a WebSocket server with engineering practical significance in GO to complete information interaction, and at the end of the course, reveal the solutions to the difficult points in the architecture technology of high-concurrency distributed systems!
