示例1: Promise
.then(function (result) {
if (result.rows.length === 0) return Promise.reject('User Not Found');
var promise = new Promise(function (resolve, reject) {
var hash = result.rows[0].password_hash;
bcrypt.compare(password, hash, function(err, res) {
if (res) resolve(result.rows[0].id);
else reject('Invalid password');
});
});
return promise
}, function (err) {示例2: function
users.create = function (username : string, email : string, password :string) {
if (!validate(username, email, password)) return Promise.reject('invalid');
return users.usernameExists(username).then(function (exists) {
if (exists) throw new ex.UserException('That username is already taken!');
}).then(function () {
return users.emailExists(email)
}).then(function (exists) {
console.log(exists)
if (exists) throw new ex.UserException('That email is already in use!');
