This repository implements a Windows DLL (version.dll) that uses DLL proxy injection to hook into the WeChat desktop client (x64, version 4.1.x). Once injected, it launches a local HTTP server on port 30001 that exposes a REST API for automating WeChat operations: sending text/image/XML messages, forwarding messages, decoding encrypted image caches, querying the user's profile, and executing arbitrary SQL on WeChat's internal SQLite databases (e.g., MicroMsg.db). The architecture is a monolithic DLL with several layers: a proxy DLL loader (version_proxy.cpp), a custom x64 hooking framework (Hook_Method.cpp) using MinHook and assembly trampolines, a set of WeChat interface implementations (wx_send.cpp, wx_send_xml.cpp, etc.) that construct internal WeChat objects using known memory offsets, and an HTTP server (http_server.cpp) built on the vendored cpp-httplib library. The project also includes a database access module (xdb/db_mgr.cpp) that scans WeChat's memory for SQLite3 API routines and executes queries directly, bypassing the need for external database drivers. External dependencies include MinHook (bundled), cpp-httplib (vendored), LZ4 compression library, and nlohmann/json. The code is heavily tied to specific WeChat version offsets and memory layouts, making it fragile across WeChat updates, but the project's update log shows active adaptation to new versions.
