我正在尝试使用SMAPI使用Java与我的Alexa技能进行交互。
以下代码失败：
package io.mirko.impl;
import com.amazon.ask.model.services.skillManagement.SkillManagementService;
import com.amazon.ask.smapi.SmapiClients;
import org.junit.jupiter.api.Test;
public class IntegrationTest {
// These come from `ask util generate-lwa-tokens` passing ClientID and SecretID from LWA
private static final String CLIENT_ID = "<client_id>";
private static final String CLIENT_SECRET = "<client_secret>";
private static final String REFRESH_TOKEN = "<refresh_token>";
private static final String SKILL_ID = "<skill_id>";
@Test
public void test() {
final SkillManagementService smapiClient = SmapiClients.createDefault(
CLIENT_ID,
CLIENT_SECRET,
REFRESH_TOKEN
);
System.out.println(smapiClient.getSkillManifestV1(SKILL_ID, "developement"));
}
}
您可以在this link找到SSL日志失败如下：

您可以获得here SSL日志以及返回的响应，
我可以看到的主要区别是，在Produced client Finished handshake message之后，在第一种情况下，超过10秒后，我收到错误，而在工作示例中，我收到了Consuming server Finished handshake message。
感谢您的帮助。
P.S。基于SSL日志差异，似乎是中断的交互从api.amazonalexa.com接收了SSL证书，该证书为DOWN。通过在浏览器中访问该主机，我收到this message。它说网站暂时不可用。我已经通过使用该主机修改了工作示例，似乎出现了相同的错误。
P.P.S。我通过使用api.amazon.com创建LWAClient设法获得了身份验证令牌。与api.amazonalexa.com的任何交互都会引发上述问题。
inal LwaClient lwaClient = LwaClient.builder()
.withAuthenticationConfiguration(
DefaultAuthenticationConfiguration.builder()
.withClientSecret(CLIENT_SECRET)
.withClientId(CLIENT_ID)
.withRefreshToken(REFRESH_TOKEN)
.build()
)
.withGrantType(GrantType.REFRESH_TOKEN)
.withApiConfiguration(DefaultApiConfiguration.builder()
.withApiClient(apiConfiguration.getApiClient())
// Without this, it does not work
.withApiEndpoint("https://api.amazon.com")
.withSerializer(apiConfiguration.getSerializer())
.build())
.build();
final SkillManagementServiceClient myClient = new SkillManagementServiceClient(
apiConfiguration, lwaClient);
// This WORKS
System.out.println(lwaClient.getAccessTokenForRefreshToken());
最后，我设法解决了这个问题。通过在调试模式下运行代码，可以捕获将要运行且与问题相关的请求。如果使用curl调用该请求，则会立即收到错误消息不解自明：
curl -vvv -X POST -H "Content-Type: application/json" -H "Authorization: Bearer Atza|XXXXX" -d "{}" https://api.amazonalexa.com/v1/skills/<skill_id>/simulations
Note: Unnecessary use of -X or --request, POST is already inferred.
