本地连接Azure MongoDB失败，现有pymongo代码调试求助

Let's walk through fixing your code to get a successful local connection to Azure Cosmos DB for MongoDB:

Corrected Working Code #

from pymongo import MongoClient
import os

# Best practice: Store your connection string in an environment variable for security
# Replace "AZURE_MONGODB_CONN_STR" with the name of your environment variable
connection_string = os.getenv("AZURE_MONGODB_CONN_STR")
client = MongoClient(connection_string)

# Access your target database
db = client.test_database

# Quick check to confirm the connection works
try:
    print("Connected successfully! Collections in database:", db.list_collection_names())
except Exception as e:
    print(f"Connection failed: {e}")

What Was Wrong With Your Original Code? #

• Misused os.getenv: os.getenv("104.211.182.12") is trying to pull an environment variable named 104.211.182.12—that's not how this function works. You need to store your full Azure MongoDB connection string in an environment variable (like AZURE_MONGODB_CONN_STR) and fetch that instead of the raw IP.
• Missing required connection parameters: Azure Cosmos DB for MongoDB needs a specific connection format that includes your account name, password, host, port, and SSL settings. The valid connection string from Azure Portal looks like this:

  mongodb://<your-account-name>:<your-password>@<your-account-name>.mongo.cosmos.azure.com:10255/?ssl=true&replicaSet=globaldb&retrywrites=false&maxIdleTimeMS=120000&appName=@<your-account-name>@
  

• Redundant db.authenticate: When you use the full connection string, authentication is handled automatically when you initialize MongoClient—you don't need to call this method separately.

How to Get Your Azure Connection String #

1. Log into the Azure Portal and open your Cosmos DB account.
2. Head to Settings > Connection Strings.
3. Copy the Primary Connection String (or Secondary) and use that in your code (either directly, or better, save it to an environment variable to keep credentials secure).
