Node.js表示不返回内容类型的响应

标签: node.js express

我是Node.js的新手,我正在关注this tutorial。一切都很好,除非我尝试返回一个json对象,如下所示:

router.get('/', function(req, res) {
  res.send({
    users: ["Will", "Laura2"]
  });
});

浏览器将“users”对象显示为“文档”类型,而不是application / json类型。任何类型(状态代码,文本/普通等)都会出现相同的情况。

"document" type instead "application/json"

我的其余代码与教程中的代码完全相同。

编辑:这是我的app.js

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

var routes = require('./routes/index');
//var users = require('./routes/users');

var app = express();

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

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(require('less-middleware')(path.join(__dirname, 'public')));
app.use(express.static(path.join(__dirname, 'public')));

app.use('/', routes);
//app.use('/users', users);

// catch 404 and forward to error handler
app.use(function(req, res, next) {
  var err = new Error('Not Found');
  err.status = 404;
  next(err);
});

// error handlers

// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
  app.use(function(err, req, res, next) {
    res.status(err.status || 500);
    res.render('error', {
      message: err.message,
      error: err
    });
  });
}

// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
  res.status(err.status || 500);
  res.render('error', {
    message: err.message,
    error: {}
  });
});


module.exports = app;

编辑:这是我的index.js

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

/* GET home page. */
//router.get('/', function(req, res, next) {
//  res.render('index', { title: 'Express' });
//});


router.get('/', function(req, res) {    
  res.send({
    users: ["Will", "Laura"]
  });
});

module.exports = router;

我做错了什么?

编辑:

看起来“application / json”类型未被接受,因此浏览器将内容显示为“文档”类型。见下图:

browser console

router.get('/', function(req, res) {
  res.json({
    users: ["Will", "Laura2"]
  });
});

只需将'send'替换为'json'就可以了...... 而且,对于返回状态代码,您可以在下面使用...

router.get('/', function(req, res) {
  res.status(200).json({
    users: ["Will", "Laura2"]
  });
});
