Question

很简单的代码 但是一直出错 求指点

var express = require('express');
var router = express.Router();

/* GET home page. */
router.post('/login', function(req, res, next) {
  const { username, password } = res.body
  res.json({
      errno: 0,
      data: {
        username,
        password
      }
  })
});



module.exports = router;

var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');
const blogRouter = require('./routes/blog');
const userRouter = require('./routes/user');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');

app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', indexRouter);
app.use('/users', usersRouter);
app.use('/api/blog', blogRouter);
app.use('/api/user', userRouter);

报错信息如下
TypeError: Cannot destructure property username of ‘undefined’ or ‘null’.
