MongoDB Atlas authentication failed on Python

问题

I have deployed this Python app on Heroku and i want it to connect to a MongoDB Atlas cluster. I used my string to connect to the cluster, but for some reason i keep getting raise OperationFailure(msg % errmsg, code, response) pymongo.errors.OperationFailure: bad auth Authentication failed. I checked twice and both the user and the password are correct. Any idea on why this is happening?

from pymongo import MongoClient
import time
import random
import time
import datetime


client = MongoClient('mongodb+srv://USER:<MYPASSWORD>@test-2liju.mongodb.net/test?retryWrites=true')

db = client.one

mycol = client["tst"]


while True:


    test = int(random.randrange(-99999990,90000000,1))

    dic = {"num": test}

    result = db.tst.insert_one(dic)


    print(test)
    time.sleep(5)

回答1:

Stupid error, i had to type MYPASSWORD instead of <MYPASSWORD>, without the <>

回答2:

Don't use any special char in password, like '+' or '='.

I use OpenSSL to generate a password like u4wY9AOwnOLMY+h9EQ==. Came across bad auth Authentication failed.

After using MongoDB Compass it told me don't use special char, so I remove those and use like 'u4wY9AOwnOLMYh9EQ'.

Then it works.
