This repository provides a preconfigured Nginx reverse proxy distribution designed to bypass regional internet censorship (primarily for Pixiv, but also covering GitHub, Steam, Discord, and other services). It includes a portable Nginx binary, self-signed SSL certificate generation scripts, and a set of modular site-specific configuration files that rewrite SNI and proxy requests to real upstream IP addresses. The system requires no VPN; instead, it modifies the user's `hosts` file to redirect target domains to localhost, where Nginx intercepts the traffic. The primary entry points are Windows batch scripts (e.g., `5.调试工具（这个功能全）.bat`) for starting, stopping, and reloading Nginx, while the core configuration is in `conf/nginx.conf` which includes reusable shared proxy parameters and site-specific configs. Certificate generation is handled by a standalone batch script folder (`自签证书傻瓜式批处理包/`) that creates a root CA and signs server certificates for all proxied domains. The repository is not a development framework or data pipeline; it is an end-user tool for circumventing censorship, with a strong emphasis on easy setup and maintenance through regular IP list updates.
