sea*_*105 6 javascript node.js passport.js
我试图将这个passport.js示例分解为最基本的元素.我一直收到401(未经授权)的消息,无法弄清楚原因.任何帮助将不胜感激.
谢谢!
Node.js文件:
var http = require('http'),
express = require('express'),
passport = require('passport'),
LocalStrategy = require('passport-local').Strategy,
flash = require('connect-flash');
var port = process.env.PORT || 8080;
passport.serializeUser(function(user, done) {
done(null, user);
});
passport.deserializeUser(function(obj, done) {
done(null, obj);
});
passport.use(new LocalStrategy(
function(username, password, done) {
console.log("LocalStrategy working...");
return done(null, { id: 1, username: 'Joe', password: 'schmo'});
}
));
var app = express();
app.configure(function(){
app.use(express.static(__dirname + '/app'));
app.use(express.cookieParser('big secret'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieSession());
app.use(flash());
app.use(passport.initialize());
app.use(passport.session());
app.use(app.router);
});
app.get('/', function (req, res) {
res.sendfile(__dirname + '/index.html');
});
app.post('/login', passport.authenticate('local'), function (req, res) {
console.log("authenticated....");
res.end();
});
app.listen(port);

新express.js(4.x和更高版本)以及passport.js的所有用户都可能遇到"丢失凭据"问题,因为默认情况下不会解析POST数据.要修复它,请安装body-parser npm install body-parser并在代码中使用:
var bodyParser = require( 'body-parser' );
app.use( bodyParser.urlencoded({ extended: true }) );
来自@ivarni的好点:app.use( bodyParser.urlencoded({ extended: true }) );必须在注入任何护照中间件之前放置.

index.html或登录页面是什么样的？在你的帖子上,你需要确保你至少发送了一个username带有password字段的字体.如果您发送没有这些帖子的帖子,您将收到Missing credentials错误消息.如果要更改这些,可以修改本指南中显示的参数.
您可以通过添加路由来捕获登录错误来自行检查,并在您的呼叫中指定该路由passport.authenticate.
app.post('/login',
passport.authenticate('local', { failureRedirect: '/loginerror', failureFlash: true }),
function(req, res) {
res.redirect('/');
});
app.get('/loginerror') function(req,res) {
console.log(req.flash('error'));
res.redirect('/login');
}
我已修改您的示例以添加必要的表单.此外,如果有任何错误,则会在登录页面上呈现.例如,如果您只输入用户名而不是密码,则会看到"缺少凭据"错误消息.希望这可以帮助!
