我编写了一个简单的程序来测试我是否可以使用Amazon Lex Java API与机器人交谈。当我运行时，我会得到一个 unknownhostexception：runtime.lex.eu-west-1.amazonaws.com

现在有人如何解决这个问题？我是否可能无法将HTTP-要求从我的公司网络中发送出来？
太多代码：
package ChatBot;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.lexruntime.AmazonLexRuntime;
import com.amazonaws.services.lexruntime.AmazonLexRuntimeClientBuilder;
import com.amazonaws.services.lexruntime.model.PostTextRequest;
import com.amazonaws.services.lexruntime.model.PostTextResult;
public class ChatbotMain {
public static void main(String[]args){
AmazonLexRuntime client = AmazonLexRuntimeClientBuilder.standard().withRegion(Regions.US_EAST_1).build();
PostTextRequest textRequest= new PostTextRequest();
textRequest.setBotName("BookTrip");
textRequest.setBotAlias("BookTripBot");
textRequest.setUserId("christester");
textRequest.setInputText("someText");
PostTextResult result = client.postText(textRequest);
System.out.println(result.getDialogState());
}
}
谢谢，

问题是我的公司网络不允许与外部网络服务进行通信。我必须使用代理或网关来这样做
