Question

AWS Appsync订阅不会触发事件。我没有从套接字接收事件。该监视程序似乎工作正常，因为如果我传递了错误的令牌（用于测试），则会触发onFailure事件。

我所做的是：

更新我的项目gradle：

classpath 'com.amazonaws:aws-android-sdk-appsync-gradle-plugin:2.7.+'

更新我的应用gradle：

apply plugin: 'com.amazonaws.appsync'

和依赖项：

implementation 'com.amazonaws:aws-android-sdk-appsync:2.7.+' 
implementation 'org.eclipse.paho:org.eclipse.paho.client.mqttv3:1.2.0'
implementation 'org.eclipse.paho:org.eclipse.paho.android.service:1.1.1'

将这些文件放入app / src / main / graphql

queries.graphql

subscription subscribeToNotify($userId: ID!, $deviceId: ID!){ subscribeToNotify(userId: $userId, deviceId: $deviceId){ userId deviceId body } }

schema.json（从控制台下载）

我的配置json是：

{
"UserAgent": "aws-amplify-cli/0.1.0",
"Version": "1.0",
"IdentityManager": {
    "Default": {}
},
"AppSync": {
    "Default": {
        "ApiUrl": "https://XXX",
        "Region": "eu-west-1",
        "AuthMode": "OPENID_CONNECT"
    },
    "Demo": {
        "ApiUrl": "https://XXX",
        "Region": "eu-west-2",
        "AuthMode": "OPENID_CONNECT"
    }
}

}

我的活动

 private lateinit var appSyncClient : AWSAppSyncClient
    private lateinit var watcher: AppSyncSubscriptionCall<SubscribeToNotifySubscription.Data>

    private var callback:AppSyncSubscriptionCall.Callback<SubscribeToNotifySubscription.Data> = object : AppSyncSubscriptionCall.Callback<SubscribeToNotifySubscription.Data> {

        override fun onResponse(response: Response<SubscribeToNotifySubscription.Data>) {
            runOnUiThread {
                Timber.i("Subcription onResponse invoked  $response")
                Timber.e("Subcription onResponse invoked  $response")
                Timber.d("Subcription onResponse invoked  $response")
            }
        }
        override fun onCompleted() {
            Timber.i("Subcription onCompleted invoked")
        }

        override fun onFailure(e: ApolloException) {
            Timber.e("Subcription ERROR $e")
        }
    }

override fun subscribeToNotification(userID: String, deviceID: String, clearToken:String) {
        try{

            Timber.d("subscribeToNotification INVOKED")

            val clientConfiguration : AWSConfiguration =  AWSConfiguration(this)

            appSyncClient =  AWSAppSyncClient.builder().context(applicationContext).awsConfiguration(clientConfiguration).oidcAuthProvider { clearToken }.build()
            //subscribeToNotify

            var app_event_subscription = SubscribeToNotifySubscription.builder().deviceId(deviceID).userId(userID!!).build()

            watcher = appSyncClient.subscribe(app_event_subscription)
            watcher.execute(callback)

        }catch (ex:Exception){
            Timber.e("EXCEPTION CONNETING "+ex.message)
        }
    }

当后端向我发送通知时，日志控制台中什么也没有出现，但我可以阅读到该替换已完成：
