使用mongo的简单示例，用于为ie Angular客户端提供用户认证的API

在app.js

var express = require('express');
var MongoStore = require('connect-mongo')(express);

// ...

app.use(express.cookieParser());
// obviously change db settings to suit
app.use(express.session({
    secret: 'blah1234',
    store: new MongoStore({
        db: 'dbname',
        host: 'localhost',
        port: 27017
    })
}));

app.use(app.router);

对于你的路线是这样的:

// (mongo connection stuff)

exports.login = function(req, res) {

    var email = req.body.email;
    // use bcrypt in production for password hashing
    var password = req.body.password;

    db.collection('users', function(err, collection) {
        collection.findOne({'email': email, 'password': password}, function(err, user) {
            if (err) {
                res.send(500);
            } else {
                if(user !== null) {
                    req.session.user = user;
                    res.send(200);
                } else {
                    res.send(401);
                }
            }
        });
    });
};

然后在你需要认证的路由中，你可以检查用户会话:

if (!req.session.user) {
    res.send(403);
}

关于手摇方法，要注意一点:

我很失望地看到，本文中建议的一些代码示例并不能防止会话固定或定时攻击等基本身份验证漏洞。

与这里的一些建议相反，身份验证并不简单，处理解决方案也不总是简单的。我推荐passsportjs和bcrypt。

但是，如果你决定着手解决问题，可以看看express js提供的例子，以获得灵感。

祝你好运。

几年过去了，我想介绍我的Express身份验证解决方案。它叫做Lockit。你可以在GitHub上找到这个项目，也可以在我的博客上找到一个简短的介绍。

那么与现有的解决方案有什么不同呢?

easy to use: set up your DB, npm install, require('lockit'), lockit(app), done routes already built-in (/signup, /login, /forgot-password, etc.) views already built-in (based on Bootstrap but you can easily use your own views) it supports JSON communication for your AngularJS / Ember.js single page apps it does NOT support OAuth and OpenID. Only username and password. it works with several databases (CouchDB, MongoDB, SQL) out of the box it has tests (I couldn't find any tests for Drywall) it is actively maintained (compared to everyauth) email verification and forgot password process (send email with token, not supported by Passport) modularity: use only what you need flexibility: customize all the things

看一下这些例子。

下面是我的一个项目中的一些基本身份验证代码。我使用它来对付CouchDB和额外的认证数据缓存，但我剥离了这些代码。

在请求处理周围包装一个身份验证方法，并为身份验证不成功提供第二个回调。成功回调将获得用户名作为附加参数。不要忘记在失败回调中正确处理错误或缺少凭据的请求:

/**
 * Authenticate a request against this authentication instance.
 * 
 * @param request
 * @param failureCallback
 * @param successCallback
 * @return
 */
Auth.prototype.authenticate = function(request, failureCallback, successCallback)
{
    var requestUsername = "";
    var requestPassword = "";
    if (!request.headers['authorization'])
    {
        failureCallback();
    }
    else
    {
        var auth = this._decodeBase64(request.headers['authorization']);
        if (auth)
        {
            requestUsername = auth.username;
            requestPassword = auth.password;
        }
        else
        {
            failureCallback();
        }
    }


    //TODO: Query your database (don't forget to do so async)


    db.query( function(result)
    {
        if (result.username == requestUsername && result.password == requestPassword)
        {
            successCallback(requestUsername);
        }
        else
        {
            failureCallback();
        }
    });

};


/**
 * Internal method for extracting username and password out of a Basic
 * Authentication header field.
 * 
 * @param headerValue
 * @return
 */
Auth.prototype._decodeBase64 = function(headerValue)
{
    var value;
    if (value = headerValue.match("^Basic\\s([A-Za-z0-9+/=]+)$"))
    {
        var auth = (new Buffer(value[1] || "", "base64")).toString("ascii");
        return {
            username : auth.slice(0, auth.indexOf(':')),
            password : auth.slice(auth.indexOf(':') + 1, auth.length)
        };
    }
    else
    {
        return null;
    }

};

var MongoStore = require('connect-mongo')(express);

// ...

app.use(express.cookieParser());
// obviously change db settings to suit
app.use(express.session({
    secret: 'blah1234',

        db: 'dbname',
        host: 'localhost',
        port: 27017
    })
}));

app.use(app.router);

// (mongo connection stuff)

exports.login = function(req, res) {

    var email = req.body.email;
    // use bcrypt in production for password hashing
    var password = req.body.password;

    db.collection('users', function(err, collection) {
        collection.findOne({'email': email, 'password': password}, function(err, user) {
            if (err) {
                res.send(500);
            } else {
                if(user !== null) {
                    req.session.user = user;
                    res.send(200);
                } else {
                    res.send(401);
                }
            }
        });
    });
};

然后在你需要认证的路由中，你可以检查用户会话:

if (!req.session.user) {
    res.send(403);
}

如果您需要使用Microsoft Windows用户帐户进行SSO(单点登录)身份验证。你可以试试https://github.com/jlguenego/node-expose-sspi。

它会给你一个要求。Sso对象，其中包含所有客户端用户信息(登录名、显示名、sid、组)。

const express = require("express");
const { sso, sspi } = require("node-expose-sspi");

sso.config.debug = false;

const app = express();

app.use(sso.auth());

app.use((req, res, next) => {
  res.json({
    sso: req.sso
  });
});

app.listen(3000, () => console.log("Server started on port 3000"));
