我有一个应用程序的NodeJS这猫鼬模式:为什么我不能访问猫鼬模式的方法?
const mongoose = require('mongoose'),
Schema = mongoose.Schema,
sodium = require('sodium').api;
const UserSchema = new Schema({
username: {
type: String,
required: true,
index: { unique: true }
},
salt: {
type: String,
required: false
},
password: {
type: String,
required: true
}
});
UserSchema.methods.comparePassword = function(candidatePassword, targetUser) {
let saltedCandidate = candidatePassword + targetUser.salt;
if (sodium.crypto_pwhash_str_verify(saltedCandidate, targetUser.password)) {
return true;
};
return false;
};
module.exports = mongoose.model('User', UserSchema);
而且我创造了这个路线文件。
const _ = require('lodash');
const User = require('../models/user.js'); // yes, this is the correct location
module.exports = function(app) {
app.post('/user/isvalid', function(req, res) {
User.find({ username: req.body.username }, function(err, user) {
if (err) {
res.json({ info: 'that user name or password is invalid. Maybe both.' });
};
if (user) {
if (User.comparePassword(req.body.password, user)) {
// user login
res.json({ info: 'login successful' });
};
// login fail
res.json({ info: 'that user name or password is invalid Maybe both.' });
} else {
res.json({ info: 'that user name or password is invalid. Maybe both.' });
};
});
});
};
然后,我使用邮递员拨打127.0.0.1:3001/user/isvalid
与适当的身体内容。终端说告诉我TypeError: User.comparePassword is not a function
并崩溃的应用程序。
由于if (user)
位通过,这表明我已经从Mongo中正确检索了一个文档并拥有User模式的实例。为什么该方法无效?
ETA:模块出口我无法复制/粘贴最初
添加到最终用户模型模块的:'module.exports = mongoose.model( '用户',UserSchema);' – dNitro
@dNitro我未能复制/粘贴,但它在我的实际代码。接得好。编辑添加它 –
