我想输入一个RequestList，这样req.params和req.body的类型就像这个接口一样

interface UpdateNoteParams {
    noteId: string,
}

interface UpdateNoteBody {
    title?: string,
    text?: string,
}

字符串
我这样做

export const updateNote : RequestHandler<UpdateNoteParams, unknown, UpdateNoteBody, unknown> = async (req: Request, res: Response, next: NextFunction)

型
但我得到了这个错误：

Type '(req: Request, res: Response, next: NextFunction) => Promise<void>' is not assignable to type 'RequestHandler<UpdateNoteParams, unknown, UpdateNoteBody, unknown, Record<string, any>>'.
  Types of parameters 'req' and 'req' are incompatible.
    Type 'Request<UpdateNoteParams, unknown, UpdateNoteBody, unknown, Record<string, any>>' is not assignable to type 'Request<ParamsDictionary, any, any, ParsedQs, Record<string, any>>'.
      Types of property 'params' are incompatible.
        Type 'UpdateNoteParams' is not assignable to type 'ParamsDictionary'.
          Index signature for type 'string' is missing in type 'UpdateNoteParams'.ts(2322)

我不知道我是否需要扩展ParamsDictionary或类似的东西，我搜索了很多，但我没有得到如何正确键入请求的答案
提前感谢！！

你就快成功了，我相信这应该行得通：

export const updateNote: RequestHandler<UpdateNoteParams, unknown, UpdateNoteBody, unknown> = async (
  req: Request<UpdateNoteParams, unknown, UpdateNoteBody, unknown>,
  res: Response,
  _next: NextFunction
) => {
  // Now you can use req.params and req.body with the specified types
  const { noteId } = req.params;
  const { title, text } = req.body;

  // ... business logic

  res.status(200).send('Note updated successfully');
};
