Knoten JS MongoDB POST Fehler

Question

Wenn ich versuche, in die DB zu posten, wird Fehler angezeigt: 'Kann nicht POST/api/postCampaign' und POST http://127.0.0.1:50945/api/postCampaign 404 (nicht gefunden). Ich versuche, Daten in mongodb Datenbank zu speichern. Dieser Code verwendet, um zu arbeiten und der Mungo war Modulo Datenbank verbunden, aber nach einiger Zeit versuche ich, den Code zu wiederholen, aber der Modulo.io ist nicht mehr verfügbar, also änderte ich die Verbindung URI. Nicht sicher, ob es gibt alles, was ich bin fehlt

Meine Codes

server.js

var express = require('express'); 
var app = express(); 
var mongoose = require('mongoose'); 
var morgan = require('morgan'); 
var bodyParser = require('body-parser'); 
var port = process.env.PORT || 3000; 

//Database connection 
mongoose.connect('mongodb://localhost/myappdatabase'); 

app.use(express.static(__dirname + '/public')); 
app.use(express.static(__dirname + '/dist')); 
app.use(bodyParser.urlencoded({'extended':'true'})); 
app.use(bodyParser.json()); 
app.use(bodyParser.json({ type: 'application/vnd.api+json' })); 
app.use(morgan('dev')); 

//Database Schema/Model 
var Schema = mongoose.Schema; 

var campaignSchema = new Schema({ 
    goalAmount: String, 
    campaignTitle: String 
}); 

var Campaign = mongoose.model('Campaign', campaignSchema); 

//Routes 
app.get('/startCampaign', function(req, res){ 
     res.sendfile('./public/views/start-campaign.html'); 
}); 

app.post('/api/postCampaign', function(req, res) { 

    Campaign.create({ 
     goalAmount : req.body.goalAmount, 
     campaignTitle: req.body.campaignTitle, 
     done : false 

    }); 
}); 


app.listen(port); 
console.log('App listening on port' + port); 

MainController.js

appTitan.controller('mainController', ['$scope', '$http', function($scope, $http){ 
    // Signup form 
    $scope.form = 'signup'; 

    $scope.switchForm = function(newForm){ 
     $scope.form = newForm; 

    }; 

    // Start camapaign 
    $scope.startCampaignData = {}; 
    $scope.createCampaign = function(){ 
     $http.post('/api/postCampaign', $scope.startCampaignData) 
      .success(function(data) { 
       console.log(data); 
      }) 
      .error(function(data) { 
       console.log('Error: ' + data); 
      }); 
    }; 
}]);

Answer 1

Sie Versuche es um eine HTTP-Anfrage an die Datenbank zu stellen. Das ist nicht möglich. Sie sollten eine Anfrage an Ihren Node-Server stellen, der wiederum Daten an die DB schreiben soll.

Versuchen Sie, Ihre Anfrage zu diesem Endpunkt zu senden: http://localhost:3000/api/postCampaign
