发布请求问题

Question

I'm trying to print the data received from the body yet not working. Here is my attempt ...

router.post('/api/main',(req,res) => {

  if(req.error){
    res.status(400).send(error.details[0].message);
    return;
  }
   res.send(req.body.message)
})

on postmen Im making a post request like these: localhost:5000/api/main/ the body looks like these: JSON

{
  "message": "hello"
}

However, im getting this response

{
    "success": false,
    "msg": {}
}

What am I missing

Answer 1

Add body parser as middleware on your post router.

Here's the proper way to set your body parser middleware.

router.use(bodyParser.urlencoded({extended: true});
router.post('/api/main', (req, res) ...)

You may also want to use bodyParser.json()

Answer 2

在您的索引文件中，在使用任何路由器之前，添加 app.use(bodyParser.urlEncoded({extended: true}));
