Javascript 无法使用带有X509用户的mongoose连接到MongoDB

我在我的项目中使用nodeJS，并使用mongoose模块连接到mongodb。使用用户名/密码方法连接工作正常。但是，当更改为X509身份验证时，我无法连接到数据库

连接到DB时引发错误-

“err”：{“name”：“MongoError”，“message”：“auth failed”，“ok”：0，“errmsg”：“auth failed”，“code”：18}

node version - v8.11.3
npm version  - 5.6.0
Mongo Db version - 3.4.14
mongoose version in package json - "^4.8.7" 

下面的代码片段

var mongoose = require("mongoose");
mongoose.Promise = global.Promise
var connection = null;
var dbString = "mongodb://host1:10901,host2:1902/dbname?replicaSet=replset&readPreference=secondaryPreferred";
var fs = require('fs')

connection = mongoose.createConnection(dbString, {
    user: encodeURIComponent("C=US,ST=California,O=Company Inc.,OU=management:group.123456,CN=dbname-role-user-repl.mydomain.com"),
    auth: { authMechanism: "MONGODB-X509", authSource: '$external' },
    server: {
        ssl: true,
        sslValidate: true,
        sslCA: fs.readFileSync(path to CA file),
        sslCert: fs.readFileSync(path to cert file),
        sslKey: fs.readFileSync(path to kep file),
        sslPass: "password"
    }
});

connection.once("open", function () {
    console.log("App is connected to  DB -- " + dbString);
});
connection.once("close", function () {
    console.log("App disconnected from  DB -- " + dbString);
});
connection.on("error", function (err) {
    console.error("App failed to connect to  DB -- " + dbString, err);
});

module.exports = {
    connection: connection,
    mongoose: mongoose
}

还有其他人面临类似的问题吗？

如果这对其他人有帮助，我找到了修复方法，下面就是它

将mongoose更新到5.2.5版并删除用户字符串上的编码（即encodeURIComponent）解决了该问题
