node.js - 为什么 request.query 不再是 'any' 了？ express request.query typescript 错误

Question

在 npm i 之后，这是我尝试将查询参数传递给需要字符串的函数时得到的错误:
'string | 类型的参数查询 | (string | Query)[]' 不能分配给 'string' 类型的参数。
类型 'Query' 不可分配给类型 'string'.ts(2345)

import express from "express";
async function getProductsImagesByShopEvent(req: express.Request, res: express.Response, 
next: express.NextFunction) {
  try {
    const params = req.query;
    if (!params || !params.shopEventId)
        throw new CustomError("params are missing in /business/getProductsImagesByShopEvent", 400, "params are missing");

    const shopEvent = new ShopEvent();
    const events = await shopEvent.getProductsImagesByShopEvent(params.shopEventId);
    res.json(events);
  }
  catch (error) {
    next(error);
  }
}

async getProductsImagesByShopEvent(shopEventId: string) {
}

错误在 params.shopEventId..
如果我添加: const params = (req.query as any);有用

这使得 express 在类型上更加严格。您必须添加类型。

const shopEventId: string = req.query.shopEventId as string
