Express + Postman没有回复

Question

I cannot seem to POST data via Postman & Express. My POST verb code is as follows

app.use(bodyParser.urlencoded({extended:true}));
app.use(bodyParser.json());

var fdbRouter = express.Router();
fdbRouter.route('/films')
//post verb
.post(function (req, res) { 

var item = new Film(req.body);
console.log(item);
//item.save();
res.status(201).send(item);

})

And my Postman setup is as follows

I have befriended google and came up with this 1. Node.js/Express form post req.body not working 2. req.body empty on posts 3. Express + Postman, req.body is empty 4. `express` app - not able to test the `post` request using `postman`

PS The watched item in postman is default in the mongoose schema i have so it's created regardless whether express works or not.

Whenever I have worked with a post request in express it's been formatted as below (assuming you're using mongoDB):

var express = require('express');
var fdbRouter = express.Router();
var model = require("<FILE TO IMPORT MODEL>") //This file will differ, but you need to import the model you created for films in your DB
var FilmModel = model.Film //also depends on how you exported your model in your dbFiles. Either way you need this model as the blue print for your post request

//I'm also assuming here that you're calling /films correctly and have it sourced as such in your app.js so you don't need /api/films as you have listed in your postman setup image 

fdbRouter.post('/films', function(req,res){
  var newfilm = new FilmModel()
  newFilm.title = req.body.Title
  newFilm.year =  req.body.Year
  newFilm.genre = req.body.Genre
  newFilm.save(function(err, savedObject){
    if(err){
      console.log(err)
      res.status(500).send()
    }else{
      res.send(savedObject)
    }
  })
})

Please note: this code example assumes a test db with a schema and model has been setup and is available for import to your routes file.

Let me know if this puts you on the right track!
