Question

我尝试使用x-www-formurlencoded通过邮递员测试我的代码写入mongodb，但我一直收到这个错误：

<!DOCTYPE html>
<html>
    <head>
        <title></title>
        <link rel="stylesheet" href="/stylesheets/style.css">
        </head>
        <body>
            <h1>Not Found</h1>
            <h2>404</h2>

所以我要做的是创建一个具有平均堆栈的电子商务网站，所以我试图构建应用程序文件和文件夹以反映服务器端和客户端。这里的代码是将数据保存到数据库（mongodb），但是从我能够推断出的错误消息是，它应该以json格式返回响应，它会抛出错误消息。

exports.create = function(req, res) {
  console.log('I got called', req.body);

  var product = new Product(req.body);

  product.save(function(err) {
    if (err) {

      return res.send(400, {
        message: err
      });
    } else {

      res.json(product);
    }
  });
};

我的app.js文件

'use strict';

var express = require('express');
var path = require('path');
var favicon = require('static-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var methodOverride = require('method-override');

var routes = require('./routes/index');
var users = require('./routes/users');

/*connecting the to database*/
require('./config/db');

var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'app/views'));
app.set('view engine', 'jade');

app.use(favicon());
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(methodOverride('X-HTTP-Method-Override'));
app.use(cookieParser());



app.use(express.static(path.join(__dirname, 'public')));

app.use('/', routes);
app.use('/users', users);

/// catch 404 and forwarding 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
        });
        next();
    });
}

// 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: {}
    });
    next();
});

//Routes
require('./app/routes/product.server.routes.js')(app);

exports = module.exports = app;

请在线搜索可能的解决方案，我得到的一些建议是我需要在我的快速配置中添加方法覆盖。

我认为你错过了等式的一部分：

发布/信息 - ＆gt;连接器/驱动器 - ＆gt; mongodb的/数据库

哟不能通过Postma将JSON发布到mongo。你需要找到一个mongodb解决方案，用于javascript来玩它。例如，你可以尝试使用Node.js。在这里，我列出了连接到mongo的所有语言可能性。

http://docs.mongodb.org/ecosystem/drivers/

希望它有所帮助！

发布到mongodb后得到回复
