python-3.x - ServerSelectionTimeoutError : basicdatabase-w4eg3. mongodb.net:27017: [Errno 11001] getaddrinfo 失败

Question

我不明白为什么在将代码连接到 MongoDB 数据库时会出现此错误。这是我的代码:-

import Credentials
client = Credentials.client
db = client.VisitorBook
company = input('Enter Company Name: ')
result=db.Company_name.insert_one({'Name':company})
print(result.inserted_id)

这是我单独制作的凭据文件，并且在上面的代码中调用了此凭据模块:

from pymongo import MongoClient
from bson.objectid import ObjectId
client = MongoClient('mongodb+srv://Username:<Password>@basicdatabase-w4eg3.mongodb.net/test?retryWrites=true');

输入我的用户名和密码后，当我执行代码时，它显示此错误:

您好，像这样更改此代码部分，

import Credentials

client = Credentials.client

db = client['VisitorBook']
collection = db['Company_name']

company = input('Enter Company Name: ')
result = collection.insert_one({'Name':company})
print(result.inserted_id)

或者尝试手动运行 mongod.exe。有时您会看到 Mongod.exe 控制台卡住，在这种情况下，请点击 mongod 控制台内的 Enter 按钮进行刷新。
