Alexa skill通过语音启用技能时不请求许可（通知）

Question

当在Web或应用程序中启用（出站通知）时，有问题的技能需要一个权限。但是，当实现技能启用事件时，它不会要求用户是否给予通知权限。技能启用本身有效，但默认情况下权限为否。如何使alexa在通过语音启用时请求权限？

Alexa可以通过语音提示他们启用出站通知吗？

要通过lambda运行提醒，其他权限可能是相同的格式。

const CreateReminderIntent = {

  canHandle(handlerInput) {
    const { request } = handlerInput.requestEnvelope;
    return request.type === 'IntentRequest' && request.intent.name === 'CreateReminderIntent';
  },

  async handle(handlerInput) {
    const { requestEnvelope, serviceClientFactory, responseBuilder } = handlerInput;
    const consentToken = requestEnvelope.context.System.user.permissions
      && requestEnvelope.context.System.user.permissions.consentToken;
    if (!consentToken) {
      return handlerInput.responseBuilder
        .addDirective({
          type: "Connections.SendRequest",
          name: "AskFor",
          payload: {
            "@type": "AskForPermissionsConsentRequest",
            "@version": "1",
            "permissionScope": "alexa::alerts:reminders:skill:readwrite"
          },
          token: "<string>"
        })
        .getResponse();
    }

    try {

      const speechText = "Great! I've scheduled a reminder for you";

      const ReminderManagementServiceClient = serviceClientFactory.getReminderManagementServiceClient();
      const reminderPayload = {
        "trigger": {
          "type": "SCHEDULED_RELATIVE",
          "offsetInSeconds": "10",
          "timeZoneId": "Europe/London"
        },
        "alertInfo": {
          "spokenInfo": {
            "content": [{
              "locale": "en-GB",
              "text": "Wash the dog"
            }]
          }
        },
        "pushNotification": {
          "status": "ENABLED"
        }
      };

      await ReminderManagementServiceClient.createReminder(reminderPayload);
      return responseBuilder
        .speak(speechText)
        .getResponse();

    } catch (error) {
      console.error(error);
      return responseBuilder
        .speak('Uh Oh. Looks like something went wrong.')
        .getResponse();
    }
  }
};

可能有不同的方式，但一旦你掌握了这项技能，我相信你需要发送一张申请许可卡。据我所知，这个想法是为了确保亚马逊作为第三方许可授予者参与进来。这将在用户手机上的Alexa应用程序中弹出权限请求。这一增加的安全层只是确保客户确切地看到他们授予的权限。

在你的技能中，你可以用几种不同的方法来做这件事。您可以检查用户第一次连接的情况，并在持久客户数据层中跟踪第一次连接。或者，当你使用这部分技能时，你可以检查用户是否有权限。如果他们没有回复，告诉客户你给他们发了一张许可证。
