之后可能会迁移到 fetch API，迁移之后再做考虑（我也不知道 fetch 有没有 interceptor 对应的实现）

In paticular your case, I think you could just catch the exception and then resolve the re-login process.

try {
  const res = ctx.http.get(url)
  // ...
} catch (e) {
  if (Quester.isAxiosError(e) {
    if (e.statusCode === 401) {
      // re-login and re-request
    }
  }
}

Well, there're no RAII or something in JS, the code might be ugly but usable for now.

我倾向于在目前的实现上直接提供一套api来做。因为其实并不需要使用axios的interceptor，只需要我们wrap一些东西

目前我也是这样实现的,但这开发起来很不友好

请问能提供一些使用 axios interceptor 的示例代码吗？我有意实现相关的功能，不过想深入了解你的需求。
