    I’m building a desktop-side utility that can sit between the Chinese version of WeChat and the network, automatically capturing every request a Mini Program makes, parsing the traffic, and then replaying or altering that traffic on demand. The workflow must be almost hands-free: once the script is started, it should watch the connection, log what it sees, and let me feed back custom payloads for instant, programmatic re-submission. Target environment — The first release has to run on Windows. If you can keep the code portable enough for a later macOS or Linux build, that is a plus, but Windows support is non-negotiable. — Headless execution is preferred: I want to trigger everything from a command or a small configuration file, with no GUI pop-ups. Core capab...
