From Scratch: Building HTTP/2 and WebSocket with Raw Python Sockets
- The article discusses the implementation of HTTP/1.0, HTTP/2.0, and WebSocket protocols using pure Python sockets to understand their communication principles.
- For HTTP/1.0, the article covers server-side steps like creating a TCP socket, parsing request data using regex, and generating response data.
- HTTP/1.0 features short connections, request parsing with regex, and manual response construction for accurate headers.
- The simplified HTTP/2.0 implementation focuses on handling GET request headers and data frames, excluding HPACK compression and multiplexing support.
- HTTP/2.0 frame structure includes length, type, flags, and stream identifier, utilizing binary framing for multiplexing.
- WebSocket protocol involves an HTTP handshake and binary frame communication for full-duplex communication, with functions for parsing and building frames.
- Comparison of HTTP/1.0, HTTP/2.0, and WebSocket features highlights connection methods, protocol formats, header handling, and typical usage scenarios.
- Limitations of pure socket implementation include performance issues, security gaps, and lack of protocol intricacies handling, recommending mature libraries for production environments.
- The article concludes by emphasizing a deep understanding of network protocols, the importance of using libraries/frameworks in production, and the efficiency of WebSocket for real-time communication.
- Leapcell is recommended as a serverless web hosting platform supporting multiple languages, unlimited projects, pay-as-you-go pricing, and comprehensive documentation.
- Leapcell enables developers to deploy projects in their preferred languages with seamless scalability and transparent pricing, followed by resources for further exploration.
