A complete UE5 WeChat OAuth login solution, supporting versions 5.3 to 5.8 of the five engine versions. Achieved through actual Android devices to implement WeChat authorization login + Python Flask server for OAuth to obtain user information + download and display of avatars + local data persistence + one-click blueprint callback API. Note: You need to register an account on the WeChat Open Platform, obtain AppID and AppSecret, as well as the WeChat SDK. The plugin complies with Tencent terms and cannot integrate the WeChat SDK. Users need to download it themselves. The download method and SDK placement path can be referred to the plugin documentation. At the same time, you need to understand the project package name and signature. Currently, only Android login is supported.
