Connexion par programmation à Amazon DocumentDB

Le code suivant montre comment se connecter à Amazon DocumentDB à l'aide de Python lorsqu'il TLS est activé.

##Create a MongoDB client, open a connection to Amazon DocumentDB as a replica set and specify the read preference as secondary preferred
client = pymongo.MongoClient('mongodb://<sample-user>:<password>@sample-cluster.node.us-east-1.docdb.amazonaws.com:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false') 

##Specify the database to be used
db = client.sample_database

##Specify the collection to be used

##Insert a single document
col.insert_one({'hello':'Amazon DocumentDB'})

##Find the document that was previously written
x = col.find_one({'hello':'Amazon DocumentDB'})

##Print the result to the screen
print(x)

##Close the connection
client.close()
