My problem is in the port_password.
{
"server": "0.0.0.0",
"server_ipv6": "::",
"local_address": "127.0.0.1",
"local_port": 1080,
"timeout": 120,
"method": "aes-256-cfb",
"protocol": "origin",
"protocol_param": "",
"obfs": "tls1.2_ticket_auth",
"obfs_param": "",
"redirect": "",
"dns_ipv6": false,
"fast_open": true,
"workers": 1,
"port_password": "{\"10000\":\"pass\",\"10001\":\"pass\",\"10002\":\"pass\",}"
}
The code I used to generate JSON.
account.forEach(ssr => {
portsPasswords += JSON.stringify(ssr.port.toString()) + ':' + JSON.stringify(ssr.password.toString()) + ','
})
I want the output something like this. How can I achieve that using NodeJS and JSON.stringfy()?
{
"server": "0.0.0.0",
"server_ipv6": "::",
"local_address": "127.0.0.1",
"local_port": 1080,
"timeout": 120,
"method": "aes-256-cfb",
"protocol": "origin",
"protocol_param": "",
"obfs": "tls1.2_ticket_auth",
"obfs_param": "",
"redirect": "",
"dns_ipv6": false,
"fast_open": true,
"workers": 1,
"port_password": {
"10000":"pass",
"10001":"pass",
"10002":"pass"
}
}
reduce into an object instead:
const account = [
{ port: 10000, password: 'pass1' },
{ port: 10001, password: 'pass2' },
{ port: 10002, password: 'pass3' }
];
const port_password = account.reduce((a, { port, password }) => {
a[port] = password;
return a;
}, {});
const entireObj = {
"server": "0.0.0.0",
// etc
port_password
};
console.log(JSON.stringify(entireObj));
I am trying to execute my test over Phantom JS in nightwatchjs
I am using Selenium server with nightwatchjs and cucumber
I took the following link as a reference-
https://github.com/nightwatchjs/nightwatch/wiki/Running-tests-in-PhantomJS
There are other answers as well but none is matching mine. this might be a configuration issue but I am not able to cut it. Can someone please help me out here.

I have 2 interfaces, one mqtt and one for websocket. I noticed if I have a backend, the mqtt does not route to websocket.
I created the mosca server as below:
server = new mosca.Server(
{
interfaces:
[
{ type: "mqtt", port: 1883 },
{
type: "mqtts",
port: 8443,
credentials: { keyPath: SECURE_KEY, certPath: SECURE_CERT }
},
{ type: "http", port: 4000, bundle: true }
],
onQoS2publish: "noack",
logger: { name: 'MoscaServer', level: 'debug' },
backend: {
type: "mqtt",
json: false,
mqtt: require("mqtt"),
key: filesys.readFileSync(__dirname + "/certs/private.key"),
cert: filesys.readFileSync(__dirname + "/certs/cert.pem"),
ca: filesys.readFileSync(__dirname + "/certs/rootCA.cer"),
clientId: "randomClientId",
port: 8883,
host: "<aws IOT endpoint>.iot.<aws region>.amazonaws.com",
rejectUnauthorized: false,
protocol: "mqtts"
},
}
);
What do I need to do to route between all the 3: mqtt, websocket and the backend?
Thanks!
When I run truffle migrate all my .json files in my build/contracts directory are missing their network field. Im trying to deploy to testrpc.
This is my truffle.js file:
module.exports = {
networks: {
development: {
host: "localhost",
port: 8545,
network_id: "*", // Match any network id
gas: 4500000
}
},
solc: {
optimizer: {
enabled: true,
runs: 200
}
},
mocha: {
bail: true
}
};
Does anyone know what might be causing this?
Thanks!
With this help, I created a super user in the mongo shell: Create Superuser in mongo
user: "try1"
passw: "hello"
In mongo cmd, I have 3 databases: 'admin', 'myDatabase' and 'local'.
Now I try to use this authorized connection to the database called 'myDatabase'.
mongoose.connect('mongodb://try1:hello#localhost:27017/myDatabase');
But this is the error I get:
name: 'MongoError',
message: 'Authentication failed.',
ok: 0,
errmsg: 'Authentication failed.',
code: 18,
codeName: 'AuthenticationFailed' }
Mongoose disconnected
Mongoose disconnected through ${msg}
I had the same problem many hours ago, and after all I solve it. My code is:
mongoose.createConnection(
"mongodb://localhost:27017/dbName",
{
"auth": {
"authSource": "admin"
},
"user": "admin",
"pass": "password"
}
);
Further to #kartGIS, I've added one more option to make the connection code perfect as possible.
mongoose.connect("mongodb://localhost:27017/databaseName", {
"auth": { "authSource": "admin" },
"user": "username",
"pass": "password",
"useMongoClient": true
});
This is the correct answer now. others are not completely correct.
await mongoose.connect("mongodb://localhost:27017/db", {
poolSize: 10,
authSource: "admin",
user: "admin",
pass: "password",
useNewUrlParser: true,
useUnifiedTopology: true,
useCreateIndex: true,
useFindAndModify: false
});
Syntax:
await mongoose.connect('mongodb://username:password#host:port/database?authSource=admin');
Example:
await mongoose.connect('mongodb://myUser:myPassword#localhost:27017/myDataBase?authSource=admin');
Working fine for me on Mongodb 4.2 and Mongoose 5.7.13
Node.js
const Connect = async () => {
let url = "mongodb://localhost:27017/test_db";
try {
let client = await Mongoose.connect( url, {
poolSize: 10,
authSource: "admin",
user: "root",
pass: "root123",
useCreateIndex: true,
useNewUrlParser: true,
useUnifiedTopology: true
} );
log( "Database is connected!" );
} catch ( error ) {
log( error.stack );
process.exit( 1 );
}
}
Connect();

I have the same problem, and it solved by removing the 'authSource' param
/* Not working */
mongoose.connect("mongodb://localhost:27017/test", {
"auth": { "authSource": "admin" },
"user": "admin",
"pass": "admin123",
"useMongoClient": true
});
/* Working */
mongoose.connect("mongodb://localhost:27017/test", {
"user": "admin",
"pass": "admin123",
"useMongoClient": true
});
Tested on Mongoose-v5.0.0.
THIS ANSWER FOR MONGOOSE 6.7.0! USED IN NUXT 3
.env PART
MONGO_URI = "mongodb://localhost:27017/MyBeautifulDB"
MONGO_USERNAME = "mongoadmin"
MONGO_PASSWORD = "mystrongpassword"
DB CONNECTION PART
import mongoose from 'mongoose';
export default async (_nitroApp) => {
const config = useRuntimeConfig();
mongoose.connect(config.MONGO_URI, {
maxPoolSize: 10,
authSource: "admin",
user: config.MONGO_USERNAME,
pass: config.MONGO_PASSWORD
})
.then(() => console.log('Connected to DB'))
.catch((e) => console.log(e));
}
nuxt.config.ts - Register your db connection file to configuration.
export default defineNuxtConfig({
runtimeConfig: {
MONGO_URI: process.env.MONGO_URI,
},
nitro: {
plugins: ['#/server/db/index.ts']
}
})
I got MongoParseError: credentials must be an object with 'username' and 'password' properties when used above answers.
Add username password to auth object solved the issue
try {
await connect("mongodb://localhost:27017/dbname", {
auth: { username: "root", password: "example" },
authSource: "admin",
});
console.log("Connected to mongo db");
} catch (error) {
console.error("Error connecting to mongodb", error);
}
mongodb version 5.0.2
mongoose 6.0.4
Respectively, if your authSource is the database ('myDB' in the example) itself and you are trying to use the ConnectionOption dbName, you have to match authSource.
await mongoose.connect('mongodb://localhost:27017,' {
dbName: 'myDB',
user: 'myUser',
pass: 'asldjaskdj'
);
Will fail with error:
{
"msg": "Authentication failed",
"attr": {
"mechanism": "SCRAM-SHA-1",
"principalName": "myUser",
"authenticationDatabase": "admin",
"client": "...",
"result": "UserNotFound: Could not find user \"myUser\" for db \"admin\""
}
}
Adding authSource: 'myDB' to the connect options will work. Example:
await mongoose.connect('mongodb://localhost:27017,' {
dbName: 'myDB',
authSource: 'myDB',
user: 'myUser',
pass: 'asldjaskdj'
);
I had the same problem. I am using an older MongoDB instance. I simply added authSource=admin to the connection string and it solved the problem.
According to the latest documentation, it should be like this:
mongoose.connect("mongodb://localhost:27017/databaseName", {
"user": "username",
"pass": "password",
"authSource": "databaseName" // users are scoped to DBs
});
Tested on mongoose6.x.x
works for me. i use local database, and mongoose ver 6.9.1
.env file:
DB_HOST=127.0.0.1:27017
DB_NAME=blabla
DB_USER=blablabla
DB_PWD=blablablabla
js file:
const DB = `mongodb://${process.env.DB_HOST}/${process.env.DB_NAME}`;
mongoose
.connect(DB, {
authSource: 'admin',
user: process.env.DB_USER,
pass: process.env.DB_PWD,
})
.then(() => {
console.log('Connected to database.');
})
.catch((err) => {
console.log(err.message);
});
NOTE
This answer is not answering original question but trying to help people in similar situation using NestJS
NestJS
#Module({
imports: [
MongooseModule.forRoot(
'mongodb://mongo:27017/test',
{
auth: {
username: 'root',
password: 'test',
},
authSource: 'admin',
},
),
],
})
export class AppModule {}
I also faced the same issue but resolved it with this
mongoose.connect(mongodb://${dbUser}:${dbPwd}#${dbHost}:${dbPort}/userInfo?authSource=admin). Assuming you have the authentication setup in mongodb.
