使用 python 连接到 mongodb 地图集时出现问题

Question

I have a problem connecting to Mongo. Would appreciate help.. Thanks

client =MongoClient("mongodb+srv://srdht:srdht@srddataset.2htbr.mongodb.net/dbImages?retryWrites=true&w=majority",ssl=True,ssl_cert_reqs='CERT_NONE')
    db=client.get_database('dbImages')
    records = db.atopic
    records.count_documents({})
    new_student = {
        'name': 'ram',
        'roll_no': 321,
        'branch': 'it'
    }
    records.insert_one(new_student)
    new_students = [
        {
            'name': 'alex',
            'roll_no': 320,
            'branch': 'it'
        },
        {
            'name': 'john',
            'roll_no': 30,
            'branch': 'ece'
        }
    ]
    
    records.insert_many(new_students)

and error:

pymongo.errors.ConfigurationError: The "dnspython" module must be installed to use mongodb+srv:// URIs. To fix this error install pymongo with the srv extra:
 C:\Users\student\.windows-build-tools\python27\python.exe -m pip install "pymongo[srv]"**

Answer 1

You need to install the dnspython, try this command to install it:

python -m pip install pymongo[srv]
