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

compileOptions {

}
// Java V2

// for Remote Procedure Call to avoid "No functional channel service provider found" error while creating SessionsClient
implementation 'io.grpc:grpc-okhttp:1.15.1'
}
答案 0 :(得分:3)
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。
