reactjs - 如何将 req 值传递给 Sequelize findAll

Question

如何使用 email 从 req 传递 password 和 Sequelize findAll() 值以查询数据库中的电子邮件和密码。下面是我需要执行的选择查询；
select email, password from user where email="some_email@testmail.com";
发送请求时，我在 n/w 选项卡响应中收到以下错误:

{"message":"WHERE 参数\"email\"具有无效的\"undefined\"值"}
server.js

app.get('/service/login', async (req, res) => {
  try {
    const loginData = await UserModel.findAll({ where: { email: req.body.email, password: req.body.password} });
    console.log(loginData);
    res.status(200).json({ loginData });
  } catch (e) {
    res.status(500).json({ message: e.message });
  }
});

login.js

 const handleSubmit = (e) => {
    e.preventDefault()
    const fetchData = async () => {
      try {
        const res = await Axios.get('http://localhost:8000/service/login');
        setLoginData(res.data.loginData); 
        console.log("Get data from database:"+loginData.password);
      } catch (e) {
        console.log(e);
      }
    }
    fetchData();
  };

将 get 方法转换为 post
在节点:

app.post('/service/login'
// then you will be able to access `req.body`

在 react 中:

// you were not even passing the email and password
await Axios.post('http://localhost:8000/service/login',{ email , password });
