我正在使用node.js,passport和postgres在用户登录页面上工作。我以为我可以进行用户身份验证了。但是,当我尝试更改页面时,出现此错误,并且服务器不会加载任何内容。 {"message":"log is not defined","error":{}}
。我已经在这个错误上停留了几个小时,无法弄清楚是什么原因造成的。我猜该会议不知何故变得混乱了,但我可能是错的。我希望有人知道答案。这是我的相关代码。
我对Web开发非常陌生,因此,我确信这可能是我所缺少的简单事物。
main-config.js
(function(appConfig) {
'use strict';
// *** main dependencies *** //
const path = require('path');
const cookieParser = require('cookie-parser');
const bodyParser = require('body-parser');
const session = require('express-session');
const flash = require('connect-flash');
const morgan = require('morgan');
const nunjucks = require('nunjucks');
const passport = require('passport');
// *** view folders *** //
const viewFolders = [
path.join(__dirname, '..', 'views')
];
// *** load environment variables *** //
require('dotenv').config();
appConfig.init = function(app, express) {
// *** view engine *** //
nunjucks.configure(viewFolders, {
express: app,
autoescape: true
});
app.set('view engine', 'html');

if (process.env.NODE_ENV !== 'test') {
app.use(morgan('dev'));
}
app.use(cookieParser());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(session({

resave: false,
saveUninitialized: true
}));
app.use(passport.initialize());
app.use(passport.session());
app.use(flash());
app.use(express.static(path.join(__dirname, '..', '..', 'client')));
};
})(module.exports);
local.js
passport.use(new LocalStrategy({
usernameField: 'email',
passwordField: 'password'
},
(username, password, done) => {
return db.one("SELECT * " +
"FROM Users " +
"WHERE Email=$1", [username])
.then((result)=> {
return done(null, result);
})
.catch((err) => {
return done(null, false, {message:'Wrong user name or password'});
});
}));
passport.js
module.exports = () => {
passport.serializeUser((user, done) => {
done(null, user.userid);
});
passport.deserializeUser((id, done)=>{
log.debug("deserialize ", id);
db.one("SELECT * FROM User " +
"WHERE user_id = $1", id)
.then((user)=>{
done(null, user);
})
.catch((err)=>{
done(new Error(`User with the id ${id} does not exist`));
})
});
};
auth.js
router.post('/login', authHelpers.loginRedirect, (req, res, next) => {
passport.authenticate('local', (err, user, info) => {
if (err) { handleResponse(res, 500, 'error'); }
if (!user) {
console.log("User Not Found");
handleResponse(res, 404, 'User not found');
}
if (user) {
req.logIn(user, function (err) {
if (err) { handleResponse(res, 500, 'error'); }
handleResponse(res, 200, 'success');
});
}
})(req, res, next);
});

这是明确的错误消息-log
未在护照的以下行中定义
log.debug("deserialize ", id);
使用记录器定义日志对象,一切都会很好。或者暂时将其删除。
