node.js+express+passport.jsでlocal認証を試したメモ

Last updated at Posted at 2016-01-11

前回までで、開発環境を作成したので認証を試す。

share/Docker/express/Dockerfile.
FROM node:5.4.0

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

#gulpfileを書き出し
RUN echo "var requireDir = require('require-dir'); requireDir('webapp/gulp/tasks', { recurse: true }); " > gulpfile.js 

#package.jsonを書き出し
RUN echo '{ "name": "node_express",  "scripts": { "start": "node webapp/bin/www", "gulp":"gulp" }}' > package.json

#タスクランナーインストール
RUN npm install --save-dev gulp 
RUN npm install --save-dev require-dir 
RUN npm install --save-dev gulp-if 
RUN npm install --save-dev gulp-livereload

#サーバーインストール
RUN npm install --save-dev express 
RUN npm install --save-dev body-parser 
RUN npm install --save-dev cookie-parser 
RUN npm install --save-dev debug 
RUN npm install --save-dev jade 
RUN npm install --save-dev morgan 
RUN npm install --save-dev serve-favicon 

# ウェブソケットインストール
RUN npm install --save-dev socket.io

# DBドライバインストール
RUN npm install --save-dev mongodb

# 認証ミドルウェアインストール
RUN npm install --save-dev passport
RUN npm install --save-dev passport-local
CMD [ "npm","run","gulp", "--","watch" ]
share/shell/express_docker_start.sh
#!/bin/bash 

source "/home/vagrant/share/shell/env.conf"

# 前回のコンテナが残っているかチェック。
docker ps -a | grep $containerName_express >/dev/null 2>&1

# コンテナが残っている場合は削除。
if [ $? -eq 0 ]; then
  docker rm -f $containerName_express
fi

docker run --name $containerName_express --rm -it -p 80:3000 -p 35729:35729 -v $path_dev_dir/myExpressGenerator:/usr/src/app/webapp $imageName_express

dockerイメージを作成し、コンテナを作成する。
次に、ルーティングと認証の設定。

share/dev/myExpressGenerator/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 passport = require('passport');

// ルート設定
var routes = require('./routes/index');
var users = require('./routes/users');
var insert = require('./routes/insert.js');
var login = require('./routes/login');

var app = express();


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

// 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(express.static(path.join(__dirname, 'public')));

// 認証ミドルウェアpassportの初期化。
app.use(passport.initialize());

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

// 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;
share/dev/myExpressGenerator/views/login.jade
extends layout

block content
  h1=title
  p Welcome to #{title}
  p#id_test test
  form(action="/login", method="post")
    div
      label 
        ユーザーID：
        input(type="text", name="username")
    div
      label 
        パスワード：
        input(type="password", name="password")
    div
      input(type="submit", value="ログイン")
share/dev/myExpressGenerator/routes/login.js
var express = require('express');
var router = express.Router();

var passport = require('passport')
  , LocalStrategy = require('passport-local').Strategy;

passport.use(new LocalStrategy(
  function(username, password, done) {
    // テスト用ユーザー
    var user = {id:"test", username:"user",password:"password"};
    
    // 認証。
    if(username===user.username && password===user.password){
      return done(null, true);
    }else{
      return done(null, false, { message: 'ログインに失敗しました。' });
    }
  }
));

router.get('/',
  function(req, res, next) {
  res.render('login', { title: 'Login' });
});

router.post('/',
  passport.authenticate('local', {failureRedirect: '/login',
                                   failureFlash: false,
                                   session: false }),
  function(req, res, next){
    res.send("login success");
  }
);
module.exports = router;

これで、 http://192.168.50.10/loginにアクセスすると認証を試すことができる。
次に、セッションを試す。
