Ich schrieb ein einfaches Programm zu testen, wenn ich mit meinem Bot mit der Amazon Lex Java API sprechen kann. Wenn ich es laufen, ich ein Unknown erhalten: runtime.lex.eu-west-1.amazonaws.comAmazon Lex UnknownHostException: runtime.lex.eu-west-1.amazonaws.com

Hat nun jemand, wie dieses Problem zu lösen? Kann ich die HTTP-Anfrage nicht aus meinem Companys Netzwerk senden?
Heres der Code:
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());
}
}
Thanks a lot,
Chris
Es scheint, Sie haben etwas falsch in Ihren Anmeldeinformationen konfiguriert, wie ich in Ihrem Code sehen Sie haben die Region auf "us-east-1" gesetzt, aber in der Ausnahme, die Sie sind wies auf eu-west-1, nein? – imTachu
Entschuldigung für die Verwirrung, das waren verschiedene Versuche. Das Problem war, dass das Netzwerk meines Unternehmens keine Kommunikation mit externen Webservices erlaubt. Ich muss einen Proxy dafür verwenden. –
