In-depth Comparison of HTTP GET vs. POST Security: From Network Transmission to Best Practices
This article explores the security differences between HTTP GET and POST methods, based on technical Q&A data, analyzing their impacts on network transmission, proxy logging, browser behavior, and more. It argues that from a network perspective, GET and POST are equally secure, with sensitive data requiring HTTPS protection. However, GET exposes parameters in URLs, posing risks in proxy logs, browser history, and accidental operations, especially for logins and data changes. Best practices recommend using POST for data-modifying actions, avoiding sensitive data in URLs, and integrating HTTPS, CSRF protection, and other security measures.
