Dialogflow API v2集成问题

我正在Android上使用 Dialogflow v1 ,但我想使用 V2 ,因为它提供了更多功能,并且因为V1将于10月23日deprecated, 2019。但是我无法将API V2集成到我的代码中。这是 V1 代码:

private void initChatbot() {
    final AIConfiguration config = new AIConfiguration("Here put Client access token",
            AIConfiguration.SupportedLanguages.English,
            AIConfiguration.RecognitionEngine.System);
    aiDataService = new AIDataService(this, config);
    customAIServiceContext = AIServiceContextBuilder.buildFromSessionId(uuid);// helps to create new session whenever app restarts
    aiRequest = new AIRequest();
}

这是 V2 代码:

private void initV2Chatbot() {
        try {
            InputStream stream = getResources().openRawResource(R.raw.test_agent_credentials);
            GoogleCredentials credentials = GoogleCredentials.fromStream(stream);
            String projectId = ((ServiceAccountCredentials)credentials).getProjectId();

            SessionsSettings.Builder settingsBuilder = SessionsSettings.newBuilder();
            SessionsSettings sessionsSettings = settingsBuilder.setCredentialsProvider(FixedCredentialsProvider.create(credentials)).build();
            sessionsClient = SessionsClient.create(sessionsSettings);
            session = SessionName.of(projectId, uuid);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

当我为 V2 编写此代码时,出现此错误:

error: cannot find symbol variable test_agent_credentials

我实际上不知道什么是test_agent_credentials以及为什么要使用它。谁能告诉我应该在哪里放置console.cloud.google Dialogflowİntegration密钥ID?

这是Gradle:

apply plugin: 'com.android.application'

android {
    buildToolsVersion "28.0.3"
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.tyagiabhinav.dialogflowchat"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    repositories {
        mavenCentral()
    }


    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    // Java V2
    packagingOptions {
        exclude 'META-INF/LICENSE'
        exclude 'META-INF/DEPENDENCIES'
        exclude 'META-INF/INDEX.LIST'
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.google.apis:google-api-services-oauth2:v1-rev145-1.25.0'


    // Dialogflow SDK dependencies
    implementation 'ai.api:sdk:2.0.7@aar'
    implementation 'ai.api:libai:1.6.12'

    // Java V2
    implementation 'com.google.cloud:google-cloud-dialogflow:0.67.0-alpha'
    // for Remote Procedure Call to avoid "No functional channel service provider found" error while creating SessionsClient
    implementation 'io.grpc:grpc-okhttp:1.15.1'
}

R.raw.test_agent_credentials是指假定位于原始资源文件夹中的test_agent_credentials.json文件。此JSON文件包含您created the Dialogflow Integration service account时下载的完整凭据文件。

忽略有关使用密钥的部分。它使用gloud命令来生成要在auth标头中使用的密钥。您是通过GoogleCredentials.fromStream()调用来完成此操作的。

重要的部分来自步骤10,在此之前,您保存JSON密钥文件并将其作为原始资源提供给Android。有关Android资源的信息,请参见this information,尤其是有关原始资源的部分。原始资源应放在子文件夹“ raw”的“ resource”文件夹下。您保存在此处的文件的名称应与R.raw后的资源名称部分匹配,且不带“ json”扩展名。
