Question

我创建了一个控制器：

import { Request, Response } from "express";

export const signIn = async (req: Request, res: Response) => {
  try {
    await res.send("This is the signIn route");
  } catch (err) {
    return res.status(400).send(err);
  }
};

export default signIn;

然后我将控制器导出到我的路由处理程序中：

import express from "express";
const router = express.Router();

import signIn from "../controller/signin";
router.post("/signIn", signIn);

我的 index.ts 文件：

import express from 'express'
import authRoutes from '../src/routes/auth-routes'
import errorHandler from '../src/middlewares/error-handler'
import {connectDB} from '../src/database/db'


const app = express()
connectDB()

const port = 3005

// @Body parser
app.use(express.json())

// @Routes
app.use('/api/users', authRoutes)
app.use(errorHandler)

// @Listening port
app.listen(port, () => {
    console.log(`*********Server listening on port ${port}*******`)
   
})

但是，我收到此错误：

}

我不明白为什么会出现“没有过载匹配此调用错误”。请有人看看我上面的代码并帮助我吗？我会很感激的。

没有与此调用错误匹配的过载（Typescript/Express）
