在python中调用CosmosClient（url、key、proxy_config=d）时，我遇到了错误？

使用客户端配置和执行对Azure Cosmos DB服务的请求时

`
d=ProxyConfiguration()
d.Host='string'
d.Port=int
client = CosmosClient(url,key,proxy_config = d) `

我犯了一个错误

azure.core.exceptions.ServiceRequestError:<urllib3.connection.HTTPSConnection object at 0x0000020EC3BCCD60>: Failed to establish a new connection: [Errno 11001] getaddrinfo failed

azure.core.exceptions.ServiceRequestError:：未能建立新连接：[Errno 11001]getaddrinfo失败

将值传递给proxy_config参数的正确方法是什么

---

您可以下载官方SDK进行测试，我认为您应该使用

CosmosClient连接

而不是

CosmosClient

---

您需要指定一个

代理配置

，而不是字符串。和

ProxyConfiguration（）

接受

Host

（字符串）和

Port

（int）参数。我对代码做了一些更改，请查看一下。如果我的解决方案对您有帮助，请您将我的答案标记为，tks~您的问题解决了吗？是否有任何进展？您是否有任何来源可以解释为什么使用CosmosClient连接而不是CosmosClient？最新的样本似乎大多使用CosmosClient，尽管也有一些使用另一个
