Cosmos DB SDK的连接问题
Cosmos DB SDK的连接问题
提问于 2021-09-10 08:34:31
我正在尝试使用Java SDK连接到一个CosmosDB实例。我的代码如下所示：
public static void main(String[] args) {
String host = "https://mycosmosinstance.cosmos.azure.com:443";
String key = "mykey";
InetSocketAddress proxy = InetSocketAddress.createUnresolved("corporate.proxy.net", 8080);
ConnectionPolicy.getDefaultPolicy().setProxy(new ProxyOptions(ProxyOptions.Type.HTTP, proxy));
CosmosClient cc = new CosmosClientBuilder()
.endpoint(host)
.key(key)
.gatewayMode()
.buildClient();
cc.getDatabase("MY_DB");
cc.close();
}如示例所示，Im位于公司代理之后。不过，连接应该不是问题，因为我们的mongo客户端工作得很好。端口是开放的，因为我可以直接远程登录。我无法访问Azure控制平面。
Im获取的RuntimeExceptions显示“客户端初始化失败。请检查端点是否可访问，以及您的身份验证令牌是否有效”。令牌与mongodb客户端使用的令牌相同。
尝试连接到443和10255 (作为mongo端口)会产生404和超时。
代码是错误的吗？有人有这方面的经验吗？

如果您使用的是HTTP proxy，请确保支持SDK GatewayConnectionConfig中配置的连接数。否则，您将面临连接问题。要使用任何代理配置，Java要求您将系统环境属性java.net.useSystemProxies设置为true。
另外，如果您使用的代理需要身份验证！此documentation将身份验证信息添加到代理，这应该有助于减轻403响应。如果是这样的话，您最终可能会进入没有Netty IO线程会导致ReadTimeoutException失败的状态。
由于无效的编码模式:阻塞Netty IO线程，可能会导致低吞吐量、高延迟和io.netty.handler.timeout.ReadTimeoutException故障。解决方法是在知道操作需要时间的情况下切换线程。
在美国西部只是一个例子的地方使用.preferredRegions(Collections.singletonList("West US"))。将首选位置设置为离应用程序最近的Cosmos DB区域。
