我们正在使用新发布的Java/Kotlin API通过 Dialogflow 实现来实现 Actions on Google 。
它被称为Speech Bank。
在智能手机上进行帐户链接过程测试时，用户收到 MalformedResponse 错误，阻止了流程的完成并随后成功切换回常规流程。
日志（详情如下）包含MalformedResponse: Failed to parse Dialogflow response into AppResponse because of empty speech response消息，用户Speech bank isn't responding right now. Try again soon.在她的设备上接收消息。
以下是有关我们设置的更多详细信息：
该操作配置为使用我们自己的符合 OAuth 2 的模拟基础设施进行帐户链接。
RawText在 Dialogflow 中配置了一个意图（称为），其余交互将由自己的内部应用程序通过其 Web 挂钩处理。
到目前为止，这是状态机在 Java 中的编码方式：
public class AoGApp extends DialogflowApp {
private final static Logger log = LoggerFactory.getLogger(AoGApp.class);
public static final String GREETING = "GOOGLE_ASSISTANT_WELCOME";
@ForIntent("RawText")
//@ForIntent("actions.intent.MAIN")
public ActionResponse launchRequestHandler(ActionRequest request) {
String userId = request.getAppRequest().getUser().getUserId();
log.info("userId={}",userId);
String queryText = request.getWebhookRequest().getQueryResult().getQueryText();
log.info("queryText={}", queryText);
String speech = null;
ResponseBuilder responseBuilder = getResponseBuilder(request);
if (isBlank(userId) || GREETING.equalsIgnoreCase(queryText)) {
speech = "\nHi. I sense a great banking experience in your future, I see that your account isn't connected. "
+ "I've sent a link to your Google Assistant app that will get you started and set up in just several simple steps. "
+ "Don't worry, I'll be here waiting, just summon me when you're ready.";
responseBuilder.add(
new SignIn()
.setContext(speech));
} else {
speech = "Welcome. You can say hello.";
responseBuilder.add(speech);
}
return responseBuilder.build();
}
@ForIntent("actions.intent.SIGN_IN")
public ActionResponse getSignInStatus(ActionRequest request) {
ResponseBuilder responseBuilder = getResponseBuilder(request);
String text = "Hello from sign-in handler";
responseBuilder.add(text);
log.info(text);
return responseBuilder.build();
}
}
and the associated HttpRequest processing:
@Override
protected void handlePOST(final Request request, final HttpServletResponse response) {
try {
String rawRequest = ControllerUtils.toString(request.getReader());
String jsonResponse = app.handleRequest(rawRequest, getHeadersMap(request)).get();
log.info("Generated response:\n {}", ControllerUtils.prettyPrint(jsonResponse));
response.setContentType(APPLICATION_JSON.getMimeType());
response.getWriter().write(jsonResponse);
} catch (Exception e) {
handleError(response, e);
}
}
public final class ControllerUtils {
private final static Logger log = LoggerFactory.getLogger(ControllerUtils.class);
private static ObjectMapper mapper = new ObjectMapper();
public static String toString(BufferedReader reader) throws Exception {
String rawRequest = reader
.lines()
//.map(e -> e.concat(System.lineSeparator()))
.collect(Collectors.joining(System.lineSeparator()));
log.info("Received AoG Request {}",rawRequest);
return rawRequest;
}
public static String prettyPrint(String json) throws Exception {
return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(mapper.readValue(json, Object.class));
}
public static Map<String, String> getHeadersMap(org.eclipse.jetty.server.Request jettyRequest){
return Collections.list((Enumeration<String>) jettyRequest.getHeaderNames())
.stream()
.collect(Collectors.toMap(
name -> name,
jettyRequest::getHeader));
}
}
如上配置，OAuth 授权代码流执行正常的 OAuth 2 步骤：
命中
/login端点以提供凭据点击
/token端点获取令牌（它的值token1在下面的日志中。我们有一个工具来生成和注入我们自己的令牌，这是一个测试环境，所以我们生成了这个token1值，它似乎已成功合并到后续请求中。）
以下是交互失败的详细屏幕截图，并附有 Actions on Google 控制台提供的日志：

根据上面的设置描述，任何人都可以帮我们弄清楚是什么导致了MalformedResponse异常，以及需要改变什么来消除它。
这个例外是如此模糊，以至于它带来了无数的问题，让人不知从何开始接近它。我将在这里仅列出一些，非常感谢一些指导。
AoG 和 Dialogflow 中的意图名称之间是否存在关联？他们应该遵循任何命名约定吗？错误的原因可能在于它们以某种方式被错误命名吗？
MalformedResponse 是否可以解释为响应中缺少特定字段？由于 Google 选择公开不同消息格式（Dialogflow 和 AppResponse）之间转换的内部工作原理，是否在某处列出了 Dialogflow 响应所需的字段？
这是否暗示即使在这种情况下传递的 OAuth 消息也需要包含一些语音？
最初，
userId从 Dialogflow 收到的数据似乎始终是null，但查询文本似乎填充了GOOGLE_ASSISTANT_WELCOME，因此我们基于它的假设来启动帐户链接流逻辑null。这是一个正确的假设吗？在什么情况下
userId最初会被填充（比如在 Alexa 中，它是在为用户启用技能时自动生成的）以便else触发上述条件？由身份验证基础设施颁发并由 AoG 支持的 OAuth 令牌是否应该采用任何特定格式，即 OIDC 或 JWT。它可以是任何随机字符串吗？仍然是
token1AoG 用语中的有效令牌（就像在 Alexa 中一样）？任何配置错误的 Java 意图处理程序？我们应该对来自 AoG 帐户链接流程的响应中的哪个意图名称做出反应？
是否有一个包罗万象的意图名称，一个可以合并到 Java 应用程序中的处理程序，以促进对上述内容的进一步调试？
“空话响应”是什么意思，我们没有提供哪些预期值并导致损坏？
我们配置了哪些不应该配置的东西？
如果这很重要，这里是来自我们 webhook 的日志：
