【问题描述】：

我想用本地 mongoose 中间件更改我的错误消息。但它没有用：

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var passportLocalMongoose = require('passport-local-mongoose');

var Account = new Schema({
    username: String,
    email: String
});

Account.plugin(passportLocalMongoose,{
    IncorrectUsernameError: 'sdfsd',
    IncorrectPasswordError: 'sdfsd'
});

var User = mongoose.model('Account', Account);

module.exports = User;

这就是我的 Account.js 和登录/注册工作完美

我的问题是，当我输入错误的用户名/密码时，会出现旧消息“用户名或密码不正确”。

【解决方案1】：

您可以更改options



    var options = {
            MissingPasswordError: 'No password was given',
            AttemptTooSoonError: 'Account is currently locked. Try again later',
            TooManyAttemptsError: 'Account locked due to too many failed login attempts',
            NoSaltValueStoredError: 'Authentication not possible. No salt value stored',
            IncorrectPasswordError: 'Password or username are incorrect',
            IncorrectUsernameError: 'Password or username are incorrect',
            MissingUsernameError: 'No username was given',
            UserExistsError: 'A user with the given username is already registered'
            };

        Account.plugin(passportLocalMongoose,options);

【解决方案2】：

在选项中使用errorMessages 字段：

var options = {
    errorMessages: {
        MissingPasswordError: 'No password was given',
        AttemptTooSoonError: 'Account is currently locked. Try again later',
        TooManyAttemptsError: 'Account locked due to too many failed login attempts',
        NoSaltValueStoredError: 'Authentication not possible. No salt value stored',
        IncorrectPasswordError: 'Password or username are incorrect',
        IncorrectUsernameError: 'Password or username are incorrect',
        MissingUsernameError: 'No username was given',
        UserExistsError: 'A user with the given username is already registered'
    }
};

Account.plugin(passportLocalMongoose,options);

你可以这样做：

Account.plugin(passportLocalMongoose, { usernameField: 'email', errorMessages : { UserExistsError : '具有给定电子邮件的用户已经注册。' } });
