PUT和DELETE – REST风格的API Express MongoDB Mongoose

第一次发布。 我正在构build一个博客网站，并使用Node.js，Express.js，MongoDB和Mongoose作为我的后端。 GET和POST工作获取和创buildpost。 但是，使用POSTMAN时，PUT和DELETE不工作，因为我得到“不能删除（PUT）/ api /博客”。 我觉得这是相关的路线，特别是当我试图findById（/ api / blog /：blog_id）。

Server.js

var express = require('express'); var mongoose = require('mongoose'); var port = process.env.PORT || 8080; var logger = require('morgan'); var favicon = require('serve-favicon'); var bodyParser = require('body-parser'); var methodOverride = require('method-override'); var app = express(); mongoose.connect('mongodb://127.0.0.1:27017/blog'); var db = mongoose.connection; db.on('error', console.error.bind(console, 'connection error: ')); db.once('open', function callback () { console.log("Scrolls are ready to be written!!!"); }); app.use(logger('dev')); app.use(bodyParser.json()); app.use(bodyParser.json({ type: 'application/vnd.api+json' })); app.use(bodyParser.urlencoded({ extended: false })); app.use(bodyParser.text()); app.use(methodOverride()); app.use(express.static(__dirname + '/client')); app.use(function(req, res, next) { res.header('Access-Control-Allow-Origin', '*'); res.header('Access-Control-Allow-Methods', 'OPTIONS, GET, POST, PUT, HEAD, DELETE'); res.header('Access-Control-Allow-Headers', 'X-Requested-With, X-HTTP-Method-Override, content-type, Accept'); next(); }); // *Routes* require('./app/routes.js')(app); // *App Start* // http://localhost:8080 app.listen(port); console.log('Connected to port ' + port); exports = module.exports = app; 

应用程序/ routes.js

 var Blog = require('./models/blog'); module.exports = function(app) { // *Server Routes* // Place API calls here // Place Authentication routes here //var express = require('express'); //var router = express.Router(); // *API Routes* // Uses Mongoose to GET all Blog Posts from database app.get('/api/blog', function(req, res, next) { Blog.find(function(err, blog) { // If error if (err) return next(err); //res.send(err); res.json(blog); }); }); // Uses Mongoose to POST new Blog Posts in database app.post('/api/blog', function(req, res) { Blog.create({ title: req.body.title, body: req.body.body, author: req.body.author, comments: req.body.comments, likes: req.body.likes, dislikes: req.body.dislikes, image: req.body.image, createdOn: req.body.createdOn }, function(err, blog) { if (err) res.send(err); Blog.find(function(err, blog) { if (err) res.send(err) res.json({ message: 'Blog Post Created!' }); }); }); }); // Uses Mongoose to GET Blog Post by _id from database app.get('/blog/:blog_id', function(req, res) { Blog.findById(req.params.blog_id, function(err, blog) { if (err) res.send (err); res.json(blog); }); }) // Uses Mongoose to PUT updates for Blog Posts by _id in database app.put('/blog/:blog_id', function(req, res) { Blog.findById(req.params.blog_id, function (err, blog) { if (err) res.send(err); if (req.body.title) blog.title = req.body.title; if (req.body.body) blog.body = req.body.body; if (req.body.author) blog.author = req.body.author; if (req.body.comments) blog.comments = req.body.comments; if (req.body.likes) blog.likes = req.body.likes; if (req.body.dislikes) blog.dislikes = req.body.dislikes; if (req.body.image) blog.image = req.body.image; if (req.body.createdOn) blog.createdOn = req.body.createdOn; blog.save( function (err) { if (err) send (err); res.json({message: 'Blog Post Updated!'}); }); }); }); // Uses Mongoose to DELETE Blog Posts by _id in database app.delete('/blog/:blog_id', function(req, res) { Blog.remove({ _id: req.params.blog_id }, function (err, blog) { if (err) return res.send(err); res.json({ message: 'Blog Post Deleted'}); }); }); // API's for PUT, POST, DELETE go here // *Frontend Routes* // Route to handle all AngularJS requests app.get('*', function(req, res) { res.sendfile('./client/views/index.html'); }); };
