Menghubungkan secara terprogram ke Amazon DocumentDB

Kode berikut menunjukkan cara menghubungkan ke Amazon DocumentDB menggunakan Python ketika TLS diaktifkan.

Dalam contoh berikut, ganti masing-masing user input placeholder dengan informasi cluster Anda.

import pymongo
import sys

##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
col = db.sample_collection

##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()

Saat menyambungkan ke klaster Amazon DocumentDB yang mendukung TLS dari aplikasi Java, program Anda harus menggunakan file otoritas sertifikat (CA) AWS yang disediakan untuk memvalidasi koneksi. Untuk menggunakan sertifikat CA Amazon RDS, lakukan hal berikut:

Kode berikut menunjukkan cara menghubungkan ke dan kueri Amazon DocumentDB menggunakan versi terbaru, mongosh, atau versi shell mongo sebelumnya, saat TLS diaktifkan.

Connect ke Amazon DocumentDB dengan mongosh

Dalam contoh berikut, ganti masing-masing user input placeholder dengan informasi cluster Anda.

mongosh --tls --host cluster-end-point:27017 --tlsCAFile  global-bundle.pem --username sample-user --password password --retryWrites false

Connect ke Amazon DocumentDB dengan versi shell mongo sebelumnya

Jika Anda menggunakan IAM, Anda harus menggunakan versi mongo shell sebelumnya. Masukkan salah satu opsi perintah berikut:

mongo --ssl --host cluster-end-point:27017 --sslCAFile global-bundle.pem --username sample-user --password password

Jika Anda menggunakan versi yang sama dengan atau lebih besar dari 4.2, gunakan kode berikut untuk menghubungkan. Tulisan yang dapat dicoba ulang tidak didukung di Amazon DocumentDB. Jika Anda menggunakan shell mongo lama (bukan mongosh), jangan sertakan retryWrites=false perintah dalam string kode apa pun. Secara default, penulisan yang dapat dicoba ulang dinonaktifkan. Termasuk retryWrites=false dapat menyebabkan kegagalan dalam perintah baca normal.

mongo --tls --host cluster-end-point:27017 --tlsCAFile global-bundle.pem --username sample-user --password password
