如何在Alexa的java SDK中使用Dialog指令

Question

我正在尝试使用java skill kit创建自己的Alexa技能，并且我想使用Dialog Interface。我已经用测试版中的技能构建器创建了我的对话模型，但现在我不明白为了委托我的对话，我需要通过我的the服务返回什么。

我应该使用哪个类向Alexa发送一个命令来处理对话框中的下一轮操作？此外，我在IntentRequest类中没有dialogState属性...

首先，dialogState属性在IntentRequest中。我使用以下依赖项(maven)的1.3.1版本。要获取该值，请使用yourIntentRequestObject.getDialogState()。

<dependency>
            <groupId>com.amazon.alexa</groupId>
            <artifactId>alexa-skills-kit</artifactId>
            <version>1.3.1</version>
</dependency>

下面您将看到来自onIntent方法中的Speechlet的一些用法示例：

        if ("DoSomethingSpecialIntent".equals(intentName))
        {

            // If the IntentRequest dialog state is STARTED
            // This is where you can pre-fill slot values with defaults
            if (dialogueState == IntentRequest.DialogState.STARTED)
            {
                // 1.
                DialogIntent dialogIntent = new DialogIntent(intent);

                // 2.
                DelegateDirective dd = new DelegateDirective();
                dd.setUpdatedIntent(dialogIntent);

                List<Directive> directiveList = new ArrayList<Directive>();
                directiveList.add(dd);

                SpeechletResponse speechletResp = new SpeechletResponse();
                speechletResp.setDirectives(directiveList);
                // 3.
                speechletResp.setShouldEndSession(false);
                return speechletResp;
            }
            else if (dialogueState == IntentRequest.DialogState.COMPLETED)
            {
                String sampleSlotValue = intent.getSlot("sampleSlotName").getValue();
                String speechText = "found " + sampleSlotValue;

                // Create the Simple card content.
                SimpleCard card = new SimpleCard();
                card.setTitle("HelloWorld");
                card.setContent(speechText);

                // Create the plain text output.
                PlainTextOutputSpeech speech = new PlainTextOutputSpeech();
                speech.setText(speechText);

                return SpeechletResponse.newTellResponse(speech, card);
            }
            else
            {
                // This is executed when the dialog is in state e.g. IN_PROGESS. If there is only one slot this shouldn't be called
                DelegateDirective dd = new DelegateDirective();

                List<Directive> directiveList = new ArrayList<Directive>();
                directiveList.add(dd);

                SpeechletResponse speechletResp = new SpeechletResponse();
                speechletResp.setDirectives(directiveList);
                speechletResp.setShouldEndSession(false);
                return speechletResp;
            }
        }

创建一个新的DialogIntent

• Create aDelegateDirective并将其分配给

1. shoulEndSession标志to false，否则Alexa终止会话

在选择您的意图的SkillBuilder中，需要至少有一个标记为必需的插槽。配置发声和提示。您还可以在提示符中使用{slotNames}。
