制作MERN-stack应用程序,但删除请求功能不起作用。
这是相关代码

尝试使用邮递员发送删除请求时,显示此错误。
我搜索其他一些StackOverflow问题,但找不到答案。
在我以前的快速应用程序中,它就像一种魅力。

无法DELTE / api / todos

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="utf-8">
    <title>Error</title>
</head>

<body>
    <!--This is the error -->
    <pre>Cannot DELETE /api/todos</pre>
    <!--This is the error ^ -->
</body>

</html>


Todos.js


  const express = require('express');
  const uuid = require('uuid');
  const router = express.Router();
  const todos = require('../../Todo');

  router.get('/', (req, res) => {
      res.json(todos);
  });

  router.get('/:id', (req, res) => {
    const found = todos.some(todo => todo.id === req.params.id);

    if (!found) {
      res.status(400).json({ msg: `No meber whit id of ${req.params.id}` });
    } else {
      res.json(todos.filter(todo => todo.id === req.params.id));
    }
  });

  router.post('/', (req, res) => {
    const newEntry = {
      id: uuid.v4(),
      title: req.body.title,
      completed: false,
    };

    if (!req.body.title) {
      res.status(400).json({ msg: `Pleas include title` });
    }

    todos.push(newEntry);
    res.json(todos);
  });

  router.delete('/:id', (req, res) => {
    const found = todos.some(todo => todo.id === req.params.id);

    if (!found) {
      res.status(400).json({ msg: `No meber whit id of ${req.params.id}` });
    } else {
      todos.filter(todo => todo.id !== req.params.id);
      res.json(todos);
    }
  });

  module.exports = router;

最佳答案

router.delete('/:id', (req, res)需要一个参数id,因此实际链接应类似于DELETE / api / todos / {id},例如/ api / todos / 3

如我所知,您的请求没有参数就发送到/ api / todos
