研究方向

The issue lacks a description, so the first step is to search the codebase for all instances of XMLHttpRequest usage. Common files include network related modules. After identifying all XHR calls, replace each with the Fetch API, ensuring error handling matches the current behavior (e.g., checking response.ok). The project uses vanilla JavaScript, so no additional libraries are needed. Consult any existing comments or discussions in the issue for clarification on scope.
