节点 - 将 google openid 保存到 mongodb答案

【问题描述】：

我正在使用带有护照的 nodejs，到目前为止，我已经成功地允许用户通过 google openID 使用以下内容登录我的应用程序：

passport.use( new GoogleStrategy({
        returnURL: 'http://localhost:22169/auth/google/return',
        realm: 'http://localhost:22169/'
    },
    function(identifier, profile, done) {
        // async verification
        process.nextTick( function() {
            profile.identifier = identifier;
            return done(null, profile);
        });
    }
));

一旦我完成这项工作，我的下一步就是仅获取 openID 值并使用 mongoose 将其保存到 mongodb 中。这是我认为应该起作用的：

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/test'); 

var User = mongoose.model('User', { openId: String });

/*
  Some other stuff...
 */

passport.use( new GoogleStrategy({
        returnURL: 'http://localhost:22169/auth/google/return',
        realm: 'http://localhost:22169/'
    },
    function(identifier, profile, done) {
        User.findOrCreate({ openId: identifier }, function(err, user) {
            done(err, user);
        });
    }
));

但是当我运行节点并尝试通过谷歌登录时，我收到一条错误消息：

/Users/mporter/Sites/budgeter/b-server.js:42
        User.findOrCreate({ openId: identifier }, function(err, user) {
             ^

我认为它必须与 User 关键字有关，但我认为我做得正确并创建了一个合适的猫鼬模型。任何人都愿意伸出援助之手。

【解决方案1】：

Passport 需要在您的模型上使用findOrCreate 方法，如上所述，但此方法未内置到猫鼬模型中。试试mongoose findorcreate plugin，它会将 findOrCreate 方法添加到您指定的模型中。
