node.js的用户身份验证库？

node.js是否有任何现有的用户身份验证库？特别是我正在寻找可以为用户进行密码身份验证的东西(使用自定义后端身份验证数据库),并将该用户与会话相关联.

在我写一个auth库之前,我想我会看看人们是否知道现有的库.通过谷歌搜索找不到任何明显的东西.

如果您正在寻找Connect或Express的身份验证框架,Passport值得研究:https://github.com/jaredhanson/passport

(披露:我是Passport的开发者)

我在调查了connect-auth和everyauth后开发了Passport.虽然它们都是很棒的模块,但它们并不适合我的需求.我想要的东西更轻盈,不引人注目.

Passport被分解为单独的模块,因此您可以选择仅使用您需要的内容(仅在必要时使用OAuth).Passport也不会在您的应用程序中安装任何路由,使您可以灵活地决定何时何地进行身份验证,并可以通过挂钩来控制身份验证成功或失败时发生的情况.

例如,以下是设置基于表单(用户名和密码)身份验证的两步过程:

passport.use(new LocalStrategy(
  function(username, password, done) {
    // Find the user from your DB (MongoDB, CouchDB, other...)
    User.findOne({ username: username, password: password }, function (err, user) {
      done(err, user);
    });
  }
));

app.post('/login', 
  passport.authenticate('local', { failureRedirect: '/login' }),
  function(req, res) {
    // Authentication successful. Redirect home.
    res.redirect('/');
  });

其他策略可通过Facebook,Twitter等进行身份验证.如有必要,可以插入自定义策略.

会话+如果

我想你没有找到很多好的库的原因是使用库进行身份验证主要是过度设计的.

您正在寻找的只是一个会话活页夹:)一个会话:

if login and user == xxx and pwd == xxx 
   then store an authenticated=true into the session 
if logout destroy session

而已.

我不同意你的结论,即connect-auth插件是要走的路.

我正在使用连接但我不使用connect-auth有两个原因:

恕我直言打破connect-auth非常强大且易于阅读的洋葱圈连接架构.禁止 - 我的意见:).你可以找到关于如何连接工作非常好,短文章和洋葱圈的想法在这里.

如果你 - 正如所写 - 只想使用数据库或文件的基本或http登录.Connect-auth太大了.对于像OAuth 1.0,OAuth 2.0&Co这样的东西更多

一个非常简单的连接验证

(它是完整的.只需执行它进行测试,但如果你想在生产中使用它,请确保使用https)(并且要符合REST原则,你应该使用POST-Request而不是GET-Request b/c你改变了一个州:)

var connect = require('connect');
var urlparser = require('url');

var authCheck = function (req, res, next) {
    url = req.urlp = urlparser.parse(req.url, true);

    // ####
    // Logout
    if ( url.pathname == "/logout" ) {
      req.session.destroy();
    }

    // ####
    // Is User already validated?
    if (req.session && req.session.auth == true) {
      next(); // stop here and pass to the next onion ring of connect
      return;
    }

    // ########
    // Auth - Replace this example with your Database, Auth-File or other things
    // If Database, you need a Async callback...
    if ( url.pathname == "/login" && 
         url.query.name == "max" && 
         url.query.pwd == "herewego"  ) {
      req.session.auth = true;
      next();
      return;
    }

    // ####
    // This user is not authorized. Stop talking to him.
    res.writeHead(403);
    res.end('Sorry you are not authorized.\n\nFor a login use: /login?name=max&pwd=herewego');
    return;
}

var helloWorldContent = function (req, res, next) {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end('authorized. Walk around :) or use /logout to leave\n\nYou are currently at '+req.urlp.pathname);

            // we don't want to proceed; instead we want to show a login page

  next();
