Python - 无法将 Python 连接到 MongoDB

Question

I'm using Python 3.4 the latest version of MongoDB and already installed pymongo using

pip install pymongo

When I run this.py file

from pymongo import MongoClient

if __name__ == "__main__":
    con = MongoClient()

    db = con.test_database

    people = db.people

    people.insert({'name':'Mike', 'food':'cheese'})
    people.insert({'name':'John', 'food':'ham', 'location':'UK'})
    people.insert({'name':'Michelle', 'food':'cheese'})

    peeps = people.find()

    print("INSERT & FIND TEST")
    for person in peeps:
        print(person)

I got this error:

Traceback (most recent call last):
  File "C:/Users/Alberto/Documents/Python/Kivy/Code/testmongo.py", line 10,     in <module>
people.insert({'name':'Mike', 'food':'cheese'})

self._error_message(selector))
pymongo.errors.ServerSelectionTimeoutError: localhost:27017: [WinError 10061] No connection could be made because the target machine actively refused it

Anyone know how to fix this?

Answer 1

if you are using Local Mongodb

myclient = pymongo.MongoClient('mongodb://<yourUsername>:<yourPassword>@<IPAddress>:27017/<yourDB>?retryWrites=true&w=majority')

If you are using Atlas Mongodb

myclient = pymongo.MongoClient('mongodb+srv://<yourUsername>:<yourPassword>@<YourCluster>.mongodb.net/<yourDB>?retryWrites=true&w=majority')

Answer 2

Just try to replace the connection with the following line.

con = MongoClient('localhost', 27017)

It works fine for me.
