虽然改用 unknown 是很好的类型安全实践，但随后的 error as ... 类型断言是不安全的。如果 error 不是预期的对象结构（例如，null 或一个字符串），在访问 err.status 时会引发运行时错误。建议在访问属性前添加类型守卫，以确保 error 是一个对象。
if (typeof error === 'object' && error) {
const err = error as { status: number; body: unknown; message?: string };
if ([400, 301].includes(err.status)) {
return reply.status(err.status).send(err.body);
}
return reply
.status(500)
.send(err.body || { error: err.message || "Internal Server Error" });
}
return reply.status(500).send({ error: String(error) });

Code Review
这次的 Pull Request 在提升代码库的类型安全方面做得非常出色，移除了大量的 as any 类型断言，并替换为更具体的类型或更安全的类型守卫。为更好的错误报告和日志记录而引入的 GlobalErrorHandler 组件和控制台缓冲逻辑是一个很有价值的新功能。PlayerController.ts 和 electron/server/netease/index.ts 中的改动是编写更健壮、类型更安全代码的绝佳范例。
我主要想提出的反馈是关于代码重复。在 src/utils/initIpc.ts 中新增的控制台缓冲逻辑与 src/utils/log.ts 中引入的 createConsoleBuffer 工具函数几乎完全相同。我留下了一条建议，建议重构 initIpc.ts 以使用这个新的可复用工具函数，这将使代码更清晰、更易于维护。

这里存在大量的代码重复。formatConsoleValue、formatErrorEventMessage 函数以及 initConsoleBuffer 内部的逻辑，与 src/utils/log.ts 文件中新增的 createConsoleBuffer 工具函数几乎完全相同。
为了提高代码的可维护性并减少冗余，建议重构此处的实现，统一使用 createConsoleBuffer 工具函数。这需要移除这部分重复的代码，并修改 initIpc 函数来使用导入的工具函数。
例如，你可以在 initIpc 中这样实现：
import { createConsoleBuffer } from "./log";
// ...
const consoleBuffer = createConsoleBuffer({
bufferKey: "__splayerGlobalConsoleBuffer",
});
consoleBuffer.init();
// 为未捕获的错误添加监听器
window.addEventListener("error", (event) => {
consoleBuffer.push("error", [consoleBuffer.formatErrorEventMessage(event)]);
});
window.addEventListener("unhandledrejection", (event) => {
consoleBuffer.push("error", [consoleBuffer.formatErrorEventMessage(event)]);
});
// ... 在文件后面
window.electron.ipcRenderer.on("request-renderer-console-logs", () => {
window.electron.ipcRenderer.send("return-renderer-console-logs", consoleBuffer.getLogs());
});这种方法复用了 log.ts 中的逻辑，遵循了 DRY (Don't Repeat Yourself) 原则。
