錯誤404：無法發布/api/users/register

我正在使用 MERN Stack 構建資金管理器應用程式，但無法將資料發布到資料庫中。如果我點擊注冊按鈕，它會拋出一個無法 POST /api/users/register的錯誤，我還在 React 的 package.json 中放置了一個指向服務器的代理，但它仍然不起作用，有什么可以可以解決這個錯誤嗎？

Register.js

import { Form, message } from "antd";
import Input from "antd/lib/input/Input";
import React from "react";
import { Link } from "react-router-dom";
import "../resources/authentication.css";
import axios from "axios"

function Register() {

    const onFinish = async (values) => {
        try {
          await axios.post('/api/users/register', values)
          message.success("Registration Successful")
        } catch (error) {
          message.error("Something Went Wrong")
        }
    }

  return (
    <div className="register">
      <div className="row justify-content-center align-items-center w-100 h-100">
        <div className="col-md-5">
          <div className="lottie">
            <lottie-player

              speed="1"
              loop
              autoplay
            ></lottie-player>
          </div>
        </div>
        <div className="col-md-5">
          <Form layout="vertical" onFinish={onFinish}>
            <h1>Money Manager / Register</h1>
            <br/>
            <Form.Item label="Name" name="name">

            </Form.Item>
            <Form.Item label="Email" name="email">
              <Input />
            </Form.Item>
            <Form.Item label="Password" name="password">
              <Input />
            </Form.Item>

            <div className="d-flex justify-content-between align-items-center">
              <Link to="/login">Already Registered, Click Here To Login</Link>
              <button className="primary" type="submit">REGISTER</button>
            </div>
          </Form>

  );
}

export default Register;

uj5u.com熱心網友回復：

只需洗掉點。更改

app.use('./api/users/', userRoute)

對它

app.use('/api/users/', userRoute)
