我的护照有问题，并在Node.js项目中进行了续集。实际上，当我想注册时，我正在使用邮递员来调用/ users / signup路由，它向我显示：Unexpected''和：
::1 - - [07/Aug/2018:09:20:19 +0000] "POST /users/signup HTTP/1.1" - - "-" "PostmanRuntime/7.2.0"
Executing (default): SELECT "user_id", "username", "name", "firstname", "email", "type", "location", "password", "createdAt", "updatedAt" FROM "users" AS "users" LIMIT 1;
有代码：
/* CREATE an account */
app.post('/users/signup', (req, res) => {
db.users.find({ $or: [{ email: req.body.email }, { username: req.body.username }] }).then(user => {
if (err) {
return res.send(err);
}
if (user) {
if (user.email == req.body.email) {
return res.send("This email is already taken.")
}
return res.send("This username is already taken.")
}
else {
const data = {
username: req.body.username,
name: req.body.name,
firstname: req.body.firstname,
email: req.body.email,
location: req.body.location,
type: req.body.type,
password: req.body.password
};
db.users.create({
username: data.username,
name: data.name,
firstname: data.firstname,
email: data.email,
location: data.location,
type: data.type,
password: data.password
}).then(newUser => {
res.send("newUser saved to database")
// `req.user` contains the authenticated user.
//TODO : res.redirect('/profile/' + req.body.username);
})
.catch(err => {
console.log(err);
res.status(400).send("unable to save this newUser to database");
})
}
}).catch(err => {
console.log(err);
res.status(400).send("signup failed");
})
})
还有我的模型（db.users）：
const bcrypt = require("bcrypt-nodejs");
module.exports = (sequelize, DataTypes) => {
// TABLE USERS
const Users = sequelize.define('users', {
user_id: {
type: DataTypes.INTEGER,
primaryKey: true,
autoIncrement: true
},
username: {
type: DataTypes.STRING,
allowNull: false,
unique: true
},
name: {
type: DataTypes.STRING,
allowNull: false
},
firstname: {
type: DataTypes.STRING,
allowNull: false
},
email: {
type: DataTypes.STRING,
allowNull: false,
unique: true,
validate: {
isEmail: true
}
},
type: {
type: DataTypes.STRING,
allowNull: false,
},
location: {
type: DataTypes.STRING
},
password: {
type: DataTypes.STRING,
allowNull: false
}
});
// methods ======================
// generating a hash
Users.generateHash = function (password) {
return bcrypt.hashSync(password, bcrypt.genSaltSync(8), null);
};
// checking if password is valid
Users.validPassword = function (password) {
return bcrypt.compareSync(password, this.password);
};
//hashing a password before saving it to the database
Users.beforeCreate('save', function (next) {
var user = this;
bcrypt.hash(user.password, 10, function (err, hash) {
if (err) {
return next(err);
}
user.password = hash;
next();
})
});
return Users;
};
My passport.js :
// load all the things we need
var LocalStrategy = require('passport-local').Strategy;
var db = require('../db')
// expose this function to our app using module.exports
module.exports = function (passport) {
var User = db.users;
// =========================================================================
// passport session setup ==================================================
// =========================================================================
// required for persistent login sessions
// passport needs ability to serialize and unserialize users out of session
// used to serialize the user for the session
passport.serializeUser(function (user, done) {
done(null, user.id);
});
// used to deserialize the user
passport.deserializeUser(function (id, done) {
User.find({
where: { user_id: user_id }
})
.then(function (user) {
done(err, user);
}).catch(function (err) {
return done(err);
})
});
// =========================================================================
// LOCAL LOGIN =============================================================
// =========================================================================
// we are using named strategies since we have one for login and one for signup
// by default, if there was no name, it would just be called 'local'
passport.use('local-login', new LocalStrategy({
// by default, local strategy uses username and password, we will override with email
usernameField: 'email',
passwordField: 'password',
passReqToCallback: true // allows us to pass back the entire request to the callback
},
function (req, email, password, done) { // callback with email and password from our form
// find a user whose email is the same as the forms email
// we are checking to see if the user trying to login already exists
User.findOne({ email : email }, function (err, user) {
// if there are any errors, return the error before anything else
if (err)
return done(err);
// if no user is found, return the message
if (!user)
return done(null, false, { message: 'User not found.' }); // req.flash is the way to set flashdata using connect-flash
// if the user is found but the password is wrong
if (!user.validPassword(password))
return done(null, false, { message: 'Incorrect password.' }); // create the loginMessage and save it to session as flashdata
// all is well, return successful user
return done(null, user);
});
}));
};
我找不到问题的根源。我是Node.js的新手，而且几个小时以来一直陷于困境。这里有人可以帮我吗？
答案 0 :(得分：1)
类似这样的东西：
db.users.find({where:{id:1}})
.then(user=>{
// some code
}).error(err=>{
throw err;
})
