我正在使用快递和护照建立一个休息api后端，似乎我的本地战略没有被要求打电话。
我的应用程序的入口点如下所示：
app.js
var fs = require('fs');
var express = require('express');
var mongoose = require('mongoose');
var passport = require('passport');
var config = require('./config/config');
var morgan = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var app = express();
app.use(morgan('dev')); // log every request to the console
app.use(cookieParser()); // read cookies (needed for auth)
app.use(bodyParser.urlencoded({extended:true}));
app.use(passport.initialize());
//connect to mongodb
mongoose.connect(config.db, options);
//load models (shorten forEach)
...
require(__dirname + '/models/' + file)(mongoose);
//load passport config
require('./config/passport')(mongoose, passport);
//load routes
require('./config/routes')(app, passport);
//start server
var server = app.listen(3000, ....
routes.js
...
app.post('/auth', function(req, res){
console.log("reached auth endpoint");
console.log(req.body);
passport.authenticate('local', { session: false}, function(err, user, info){
console.log("Test:"+user);
if(err) {
console.log("Error1");
return next(err)}
if(!user){
console.log("Error2");
return res.json(401, {error: 'Auth Error!'});
}
console.log("Error3");
var token = jwt.encode({ username: user.email }, "hanswurst");
res.json({token: token});
}),
function(req, res){
console.log("passport user", req.user);
};
});
passport.js
...
passport.use(new LocalStrategy({
usernameField: 'email',
passwordField: 'password',
passReqToCallback: true
},
function(email, password, done){
console.log("TEST");
User.findOne({'email': email}, function(err, user){
if(err){
console.log("Unknown error");
return done(err);
}
if(!user){
console.log("No User found");
return done(null, false);
}
if(!user.validPassword(password)){
console.log("Password was incorrect");
return done(null, false);
}
console.log("User was found");
return done(null, user);
});
}
));
我获得表单请求的唯一结果是
reached auth endpoint
{ email: 'test@mail.com', password: 'secret' }
POST /auth - - ms - -
对我来说，请求正文看起来很好，它应该进入我的LocalStrategy。我有点无奈，因为我从这一点上没有得到任何其他控制台输出。

首先，您在routes.js中有一些基本的javascript语法错误。这一部分就在这里（为清晰起见，删除了大量代码）：
passport.authenticate(/*...*/), function(req, res) {/*..*/};
可能是您刚刚在错误的地方添加了一些console.log来电。为了消除这种混淆，passport.authenticate()不会立即执行身份验证，它会为您返回一个中间件。你会像这样使用它，例如：
var middleware = passport.authenticate(...);
app.post('/auth', middleware);
因此，为了解决您的问题，请尝试立即调用authenticate返回的中间件，如下所示：
app.post('/auth', function(req, res, next) {
console.log("reached auth endpoint");
console.log(req.body);
passport.authenticate('local', {
session: false
}, function(err, user, info) {
console.log("Test:" + user);
if (err) {
console.log("Error1");
return next(err);
}
if (!user) {
console.log("Error2");
return res.json(401, {
error: 'Auth Error!'
});
}
console.log("Error3");
var token = jwt.encode({
username: user.email
}, "hanswurst");
res.json({
token: token
});
})(req, res, next);
});
另外，我必须告诉你require缓存模块。要让config/passport.js知道猫鼬和护照，不应将它们作为参数提供：
require('./config/passport')(mongoose, passport);
只需在config/passport.js内再次要求它们：
// (in config/passport.js)
// Both of these vars point to the same thing you require'd in app.js
var mongoose = require('mongoose');
var passport = require('passport');

[编辑] 我发现了问题。因为Express不再支持body-parser等子包，所以需要单独设置它们。如果我首先完成这一切，那一切都会很好，但我只是激活了：
app.use(bodyParser.urlencoded({extended:true}));
您还需要设置
app.use(bodyParser.json());
让它正常工作。愚蠢的疏忽但仍然让我难过了3天。
<小时/> 我有同样的问题，但似乎没有什么对我有用。
我将执行顺序从上到下删除代码
玉模板
.navbar-right(ng-controller="mvNavBarLoginCtrl")
form.navbar-form
.form-group
input.form-control(placeholder='Email', ng-model='username')
.form-group
input.form-control(type='password', placeholder='password', ng-model='password')
button.btn.btn-primary(ng-click="signIn(username,password)") Sign In
下一步登录控制器
angular.module('app').controller('mvNavBarLoginCtrl',function($scope, $http){
$scope.signIn = function (username, password){
console.log('un = ' + username); // Prints fine in the console
console.log('pw = ' + password); // Prints fine in the console
$http.post('/login', {username: username, password: password}).then(function(response){
if(response.data.success){
console.log('Logged in!!');
}
else{
console.log('Failed to log in!!');
}
});
}
});
下一步路线处理程序
app.post('/login', function(req, res, next){
console.log(req.username); // Already empty
console.log(req.password); // Already empty
console.log(req.body); // Already empty
// Because of the use of AngularJS we can not call passport directly,
// missing req and res will break the code
var auth = passport.authenticate('local', function(err, user){
console.log(user); // prints undefined
if(err){return next(err);}
if(!user){res.send({success:false});}
req.logIn(user, function(err){
if(err){return next(err);}
res.send({success: true, user: user});
});
});
// call the auth function to start authenticate
auth(req, res, next);
});
下一步护照认证处理程序
var User = mongoose.model('User');
passport.use(new LocalStrategy({
username: 'username',
password: 'password'
},
function(username, password, done){
console.log("called"); // never printed
// find user based in mongoose schema see 'var User'
User.findOne({userName:username}).exec(function (err,user){
console.log(user) // never printed
if(err){return done(err);}
if(user){
return done(null, user);
}
else{
return done(null, false);
}
});
}
));
passport.serializeUser(function(user, done){
if(user) {
done(null, user._id);
}
});
passport.deserializeUser(function(id, done){
user.findOne({_id:id}).exec(function(err, user){
if(user) {
done(null, user);
}
else{
done(null, false);
}
});
});
控制台中没有错误，也没有节点输出。我很难过并且读了大约5个左右的其他类似问题的线程，没有任何效果。
如果有人能给我金色小贴士，我会永远感激不尽。
