许多教程都告诉您在 userSchema 页面中使用 bycrypt。保存新用户后,它会附带加密的密码。伟大的。然而,我认为,当我使用某些内容编辑用户时,它也会重新哈希密码,从而导致无法登录。您能给我建议一个解决方案吗?谢谢。
const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const bcrypt = require('bcrypt-nodejs');
const eventSchema = require('./eventSchema');
const userSchema = new Schema({
email: { type: String, unique: true, lowercase: true },
password: String,
eventList: [{
type: Schema.ObjectId,
ref: "event"
}],
administrator: { type: Boolean, default: false }
});
// On Save Hook, encrypt password
// Before saving a model, run this function
userSchema.pre('save', function(next) {
// get access to the user model
const user = this;
// generate a salt then run callback
bcrypt.genSalt(10, function(err, salt) {
if (err) { return next(err); }
// hash (encrypt) our password using the salt
bcrypt.hash(user.password, salt, null, function(err, hash) {
if (err) { return next(err); }
// overwrite plain text password with encrypted password
user.password = hash;
next();
});
});
});
userSchema.methods.comparePassword = function(candidatePassword, callback) {
bcrypt.compare(candidatePassword, this.password, function(err, isMatch) {
if (err) { return callback(err); }
callback(null, isMatch);
});
};
// Create the model class
const ModelClass = mongoose.model('user', userSchema);
// Export the model
module.exports = ModelClass;

也许您可以使用isModified检查密码是否被修改。
userSchema.pre('save', function(next) {
const user = this;
if (!user.isModified('password')) return next();
bcrypt.genSalt(10, function(err, salt) {
if (err) return next(err);
bcrypt.hash(user.password, salt, null, function(err, hash) {
if (err) return next(err);
user.password = hash;
next();
});
});
});
