Pymongo pymongo.errors.ServerSelectionTimeoutError 使用示例代碼時

Question

我正在嘗試運行非常簡單的代碼來弄清楚如何將 pymongo 與 MongoDB Atlas Cloud 一起使用。

這是示例代碼

import pymongo

client = pymongo.MongoClient("mongodb+srv://{myusername}:{mypassword}@cluster0-uywu8.mongodb.net/test?retryWrites=true&w=majority")
db = client.BroadwayMatch
print(db)
collection = db.Artists
print(collection)

print(collection.insert_one({'x': 1}))

BroadwayMatch 和 Artists 是我上周能夠插入的現有數據庫和 collections，我不確定發生了什么變化。 它似乎成功連接到數據庫和集合，但由於某種原因無法讀取或寫入它。 collections 的所有屬性都可以訪問，但所有方法都會導致 ServerSelectionTimeoutError。 這是此片段中的 output

Database(MongoClient(host=['cluster0-shard-00-01-uywu8.mongodb.net:27017', 'cluster0-shard-00-00-uywu8.mongodb.net:27017', 'cluster0-shard-00-02-uywu8.mongodb.net:27017'], document_class=dict, tz_aware=False, connect=True, authsource='admin', replicaset='Cluster0-shard-0', ssl=True, retrywrites=True, w='majority'), 'BroadwayMatch')
Collection(Database(MongoClient(host=['cluster0-shard-00-01-uywu8.mongodb.net:27017', 'cluster0-shard-00-00-uywu8.mongodb.net:27017', 'cluster0-shard-00-02-uywu8.mongodb.net:27017'], document_class=dict, tz_aware=False, connect=True, authsource='admin', replicaset='Cluster0-shard-0', ssl=True, retrywrites=True, w='majority'), 'BroadwayMatch'), 'Artists')

我不確定我做錯了什么，有人可以幫忙嗎？

Answer 1

您可能無法連接到 Atlas 服務器的原因：

• 您的白名單沒有啟用您當前的 IP 地址
• 您使用了錯誤的用戶名和/或密碼。 在您的情況下，您的 fString 似乎在一開始就缺少 f 。

When diagnosing these conditions cutting and pasting the MongoDB Atlas connection string (see below) for the MongoDB shell or MongoDB Compass can often expose username and/or password errors.

Answer 2

要么您的 mongo 服務器未公開，否則它不在默認端口中。 嘗試以下操作：

import pymongo
client = pymongo.MongoClient("mongodb://uname:pass@ip:port/")
db = client['BroadwayMatch']
