Flask 和 MongoEngine 出现“SSL：CERTIFICATE_VERIFY_FAILED”错误

Question

I am trying to send a GET request to my Mongo server, and this is the current issue I am having.

[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1122)')>]>

I am unable to figure out what is happening. My code looks about correct so I am a bit confused.

Here is my app/main file:

from flask import Flask

from flask_mongoengine import MongoEngine

db = MongoEngine()

# Did pip install certifi for security certifications

def create_app(config=None):
    app = Flask(__name__)
if config is not None:
    app.config.from_object(config)

db.init_app(app)

@app.route("/")
def hello():
    return "Hello World"

from user.views import user_page
# This means that we will use /user/login....
# To access the login page
app.register_blueprint(user_page, url_prefix="/user")

return app

Here is my config file:

# MONGODB_DB = 'my-db'
MONGODB_SETTINGS = {
    'host': 'mongodb+srv://jack123:coolPass@my-db.ap6mq.mongodb.net/my-db?retryWrites=true&w=majority'
}

I'd certainly appreciate any sort of help on this. This is something I have been stuck on for a while now. I don't know where to get the certificate or how to turn it off.

I doubt certifi is going to do anything automatically for MongoDB connections.

If your system doesn't come with the certificates needed for Atlas, most likely you will need to:

• Figure out/hunt down the CA certificate that Atlas uses (consult Atlas documentation, if this doesn't help you can extract the CA certificate from the connection using openssl command-line tool)
• Provide this certificate to pymongo using a URI option (consult pymongo documentation for how to do this)
