mongodb线上环境报错Db.prototype.authenticate method will...

Question

项目部署到阿里云服务器ubuntu14.04时会发生一次重启，看日志说
Db.prototype.authenticate method will no longer be available in the next major release 3.x as MongoDB 3.6 will only allow auth against users in the admin db and will no longer allow multiple credentials on a socket. Please authenticate using MongoClient.connect with auth credentials.
我在这里看到有人遇到同样的问题 https://github.com/Automattic...，说是mongoose的原因，我把mongoose升级到最新版本后还是报这个错。。。
这是我连mongodb的链接:

mongodb://blog_runner:safeblog@127.0.0.1:27017/blog-app

blog_runner是具有读写权限的。如何解决呢？

Answer 1

是与mongoose的版本有关系，我用4.7.0是没有这个提示的，升级到最新4.10.6就提示了

Answer 2

/**
 * 报错代码：
 */
mongoose.connect(DB_URL）

报错提示：

/**
 * 新增Option，特别是useMongoClient这一项后，无报错
 */
const options = {
    useMongoClient: true,
    reconnectTries: Number.MAX_VALUE, // Never stop trying to reconnect
    reconnectInterval: 500, // Reconnect every 500ms
    poolSize: 10, // Maintain up to 10 socket connections
    // If not connected, return errors immediately rather than waiting for reconnect
    bufferMaxEntries: 0
};

mongoose.connect(DB_URL,options);

此时DB_URL的写法也需要更改

/**
 * 原先错误代码
 */
DB_URL='mongodb://admin:admin@localhost:27017/mongodb?authSource=admin'

/**
 * 正确代码去掉?authSource=admin
 */
DB_URL='mongodb://admin:admin@localhost:27017/mongodb'

Answer 3

请问解决了吗？我也遇到了相同的问题

Db.prototype.authenticate method will no longer be available in the next major release 3.x as MongoDB 3.6 will only allow auth against users in the admin db and will no longer allow multiple credentials on a socket. Please authenticate using MongoClient.connect with auth credentials.

环境如下：
node v6.13.1
MongoDB v3.4.13
Mongoose v4.11.9

Mongoose 切换了很多版本4.7.0、4.10.6、4.11.9最新版均没用

let dbStr = 'mongodb://someUserName:someUserPsd@someUrl:somePort/someDatebaseName';
mongoose.Promise = global.Promise;
let db = mongoose.connect(dbStr, { useMongoClient: true } );
