Python 从Docker连接到MongoDB云时出错

我在我的笔记本电脑、服务器和另一台笔记本电脑上测试了该应用程序

我每次都更改了DNS，但这就是我遇到的问题：

pymongo.errors.ConfigurationError: None of DNS query names exist: _mongodb._tcp.xxxxxx-shard-00-00-uzn6y.mongodb.net., _mongodb._tcp.xxxxxx-shard-00-00-uzn6y.mongodb.net.

生成此错误的行是：

myclient = MongoClient(con_string)

结论是：

mongodb+srv://root:<password>@xxxxxx-xxxxxx.mongodb.net/test?retryWrites=true

以上任何一项都无法解析mongocloud实例地址

这是完整的跟踪：

During handling of the above exception, another exception occurred:

在处理上述异常期间，发生了另一个异常：

我找到了解决方案。 连接主机字符串应为：：

xxxxxxxxxx-shard-00-00-xxxxxxxxxxxx.mongodb.net:27017,xxxxxxxx-shard-00-01-xxxxxxxx.mongodb.net:27017,xxxxxxxxx-shard-00-02-xxxxxxxxx.mongodb.net:27017/test?ssl=true&replicaSet=xxxxxxxxxxxxxxx-shard-0&authSource=admin&retryWrites=true 

---

\u mongodb.\u tcp

部分看起来不正确。域名应以群集名称开头。您使用的是哪个版本的驱动程序？如果您使用的是MongoDB云，那么：连接->连接您的应用程序->选择python驱动程序3.4。或者稍后，您可以将此格式的工作连接字符串复制到数据库中
