【问题描述】：

我正在尝试通过 POSTMan 向我的技能发送警报/剩余信息。

选项 1： 范围为“alexa:skill_messaging”的身份验证令牌 API

POST /auth/o2/token HTTP/1.1
Host: api.amazon.com
Content-Type: application/x-www-form-urlencoded
User-Agent: PostmanRuntime/7.20.1
Accept: */*
Cache-Control: no-cache
Postman-Token: 2ae7afa3-c3f8-493f-b6e3-2db1e44e3a17,a4e45e8e-d0eb-4b3f-a612-e7d1959fdbe6
Host: api.amazon.com
Accept-Encoding: gzip, deflate
Content-Length: 236
Connection: keep-alive
cache-control: no-cache

grant_type=client_credentials&client_id=******************&client_secret=***********17a4f7b348982bdb4&scope=alexa%3Askill_messaging

选项 2： 具有作用域的身份验证令牌 API "alexa::alerts:reminders:skill:readwrite"

POST /auth/o2/token HTTP/1.1
Host: api.amazon.com
Content-Type: application/x-www-form-urlencoded
User-Agent: PostmanRuntime/7.20.1
Accept: */*
Cache-Control: no-cache
Postman-Token: 2ae7afa3-c3f8-493f-b6e3-2db1e44e3a17,c6765f77-6e35-419f-b614-780dae20ad4e
Host: api.amazon.com
Accept-Encoding: gzip, deflate
Content-Length: 236
Connection: keep-alive
cache-control: no-cache

grant_type=client_credentials&client_id=**************************&client_secret=************************&scope=alexa%3A%3Aalerts%3Areminders%3Askill%3Areadwrite

第 2 步： 使用 Scope 生成的令牌提交警报请求 "alexa:skill_messaging" 获取 Invalide Bearer token

如果我遗漏了什么，请告诉我，以及在哪里可以找到 Alexa Authenictaion Token API 的不同范围

【解决方案1】：

很遗憾，

“这是 Reminders API 的限制 - 您需要使用会话内访问令牌来创建提醒。您也可以在会话外运行 GET、UPDATE 和 DELETE 操作，因此请检查this out了解更多信息。”

只有与设备通话才能获得会话中访问令牌以创建提醒。

会话外 - 获取技能创建的提醒（技能消息 API）：

    const IncomingMessageHandler = {
        canHandle(handlerInput) {
            const request = handlerInput.requestEnvelope.request;
            return request.type === 'Messaging.MessageReceived'
        },
        async handle(handlerInput) {
            const { requestEnvelope, context } = handlerInput;
            console.log(`Message content: ${JSON.stringify(requestEnvelope.request.message)}`);

            try {
              const client = handlerInput.serviceClientFactory.getReminderManagementServiceClient();
              const remindersResponse = await client.getReminders();
              console.log(JSON.stringify(remindersResponse));
            } catch (error) {
              console.log(`error message: ${error.message}`);
              console.log(`error stack: ${error.stack}`);
              console.log(`error status code: ${error.statusCode}`);
              console.log(`error response: ${error.response}`);
            }

            context.succeed();
        }
    }
