Well, you did a small mistake while defining a route of the express.好吧，您在定义快车路线时犯了一个小错误。 you have app.post('api/hostels', (req, res) => {}) instead you should have app.post('/api/hostels', (req, res) => {})你有app.post('api/hostels', (req, res) => {})而你应该有app.post('/api/hostels', (req, res) => {})

You are posting to /api/requests , your endpoint shows /api/hostels .您正在发布到/api/requests ，您的端点显示/api/hostels 。 Change the endpoint on your postman to /api/hostels .将邮递员的端点更改为/api/hostels 。

There is a mistake in your post, theres a missing / in you app.post您的帖子中有错误，您的 app.post 中缺少/
it should be app.post('/api/hostels', (req, res) => { }它应该是app.post('/api/hostels', (req, res) => { }
