我已经在google上建立了一个actions项目，我应该可以在google助手中添加一个恒温器。但是，把它添加到googlehome中是行不通的，你知道为什么吗？
在“开发”选项卡中，我添加了：
实现url
客户id和密码
授权和令牌url
通过授权url，我可以（存根）登录，并返回所需的令牌： {"token_type":"bearer","access_token":"123access","expires_in":86400} 返回令牌后，我会收到一个带有请求id的sync调用，如预期的那样。我返回以下内容。

{"payload":{"agentUserId":"sampleClientId","devices":[{"traits":["action.devices.traits.TemperatureSetting"],"willReportState":true,"attributes":{"availableThermostatModes":["off","heat","cool","heatcool","on"],"thermostatTemperatureRange":{"maxThresholdCelsius":30,"minThresholdCelsius":15},"thermostatTemperatureUnit":"F"},"id":"123","type":"action.devices.types.THERMOSTAT","deviceInfo":{"swVersion":"11.4","model":"hs1234","manufacturer":"smart-home-inc","hwVersion":"3.2"}}]},"requestId":"16241058020468313677"}

这个json结构来自关于恒温器的文档。然而，一旦请求完成，我只会收到3个同步调用与完全相同的结果。我的googlehome和助手应用程序首先告诉我添加设备成功了，3秒钟后通知我出了问题。我没有从谷歌得到错误代码，所以我不确定我做错了什么。“agentuserid”属性是我添加到google控制台上的操作的客户机id，因为我不确定要添加什么。
我将在下面添加最重要的代码以使其完整。
onsync（..）方法：

@NotNull
    @Override
    public SyncResponse onSync(@NotNull SyncRequest syncRequest, @Nullable Map<?, ?> headers) {
        SyncResponse res = new SyncResponse();
        res.setRequestId(syncRequest.requestId);
        res.setPayload(new SyncResponse.Payload());

        String token = (String) headers.get("authorization");
        String user = TokenServlet.user.getUserId();
        res.payload.agentUserId = user;

        List<DevicesItem> devices = TokenServlet.user.getDevices();

        int numOfDevices = devices.size();
        res.payload.devices = new SyncResponse.Payload.Device[numOfDevices];
        for (int i = 0; i < numOfDevices; i++) {
            DevicesItem device = devices.get(i);
            SyncResponse.Payload.Device.Builder deviceBuilder =
                    new SyncResponse.Payload.Device.Builder()
                            .setId(device.getId())
                            .setType(device.getType())
                            .setTraits(device.getTraits())
                            .setWillReportState(device.isWillReportState())
                            .setDeviceInfo(
                                    DeviceProto.DeviceInfo.newBuilder()
                                            .setManufacturer(device.getDeviceInfo().getManufacturer())
                                            .setModel(device.getDeviceInfo().getModel())
                                            .setHwVersion(device.getDeviceInfo().getHwVersion())
                                            .setSwVersion(device.getDeviceInfo().getSwVersion())
                                            .build())
                    ;
            if (!Objects.isNull(device.getAttributes())) {
                String attributesJson = new Gson().toJson(device.getAttributes());
                Struct.Builder attributeBuilder = Struct.newBuilder();
                try {
                    JsonFormat.parser().ignoringUnknownFields().merge(attributesJson, attributeBuilder);
                } catch (Exception e) {
                    LOGGER.error("FAILED TO BUILD");
                }
                deviceBuilder.setAttributes(attributeBuilder.build());
            }
            res.payload.devices[i] = deviceBuilder.build();
        }

        return res;
    }
