How to escape @ in a password in pymongo connection?

Python 3.6.5 - PyMongo 3.7.0 version for connecting to an mlab instance:

from pymongo import MongoClient
import urllib.parse

username = urllib.parse.quote_plus('username')
password = urllib.parse.quote_plus('password')
client = MongoClient('mongodb://%s:%[email protected]:000000/recipe_app_testing' % (username, password))

This is the only way I have managed to connect to the mlab MongoDB instance without using flask-pymongo spun up app, I needed to create fixtures for unit tests.

Python 3.6.5 - PyMongo 3.7.0 localhost version:

from pymongo import MongoClient
import urllib.parse 

username = urllib.parse.quote_plus('username')
password = urllib.parse.quote_plus('password')
client = MongoClient('mongodb://%s:%[email protected]:27001/' % (username, password))

run in terminal :

python -m pip install pymongo[srv]

python file:

import pymongo
from pymongo import MongoClient
import urllib.parse

username = urllib.parse.quote_plus('username')
password = urllib.parse.quote_plus("password")

url = "mongodb+srv://{}:{}@cluster0-0000.mongodb.net/<dbname>?retryWrites=true&w=majority".format(username, password)
# url is just an example (your url will be different)

cluster = MongoClient(url)
db = cluster['Sample']
collection = db['temporary']

You should be able to escape the password using urllib.quote(). Although you should only quote/escape the password, and exclude the username: ; otherwise the : will also be escaped into %3A.

For example:

import pymongo 
import urllib 

mongo_uri = "mongodb://username:" + urllib.quote("p@ssword") + "@127.0.0.1:27001/"
client = pymongo.MongoClient(mongo_uri)

The above snippet was tested for MongoDB v3.2.x, Python v2.7, and PyMongo v3.2.2.

The example above assumed in the MongoDB URI connection string:

• The user is created in the admin database.
• The host mongod running on is 127.0.0.1 (localhost)
• The port mongod assigned to is 27001

For Python 3.x, you can utilise urllib.parse.quote() to replace special characters in your password using the %xx escape. An example of the same:

urllib.parse.quote("p@ssword")
