我正在使用dialogflow-android-client但现在已经发布了dialogflowV2。所以我试图使用Dialogflow new Library来实现。
以下是Android中的代码
private String projectId = "modroid-test-3aedd";
private TextView textView;
private SpeechToText toText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = findViewById(R.id.textview);
toText = new SpeechToText(this, textView);
try {
GoogleCredentials credentials = GoogleCredentials.fromStream(getResources().getAssets().open("Test-9d8a744b520a.json"))
.createScoped(newArrayList("https://www.googleapis.com/auth/compute"));
credentials.toBuilder().build();
} catch (IOException e) {
e.printStackTrace();
}
textView = findViewById(R.id.textview);
new MyAsync(projectId).execute();
}
@Override
protected void onStart() {
super.onStart();
toText.start();
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
toText.start();
}
class MyAsync extends AsyncTask {
private String projectId;
MyAsync(String projectId) {
this.projectId = projectId;
}
@Override
protected Object doInBackground(Object[] objects) {
try {
detectIntentStream(projectId, null, "7fff90e6-3879-4ed5-ad85-058531b3002a", "en-US");
} catch (Throwable throwable) {
throwable.printStackTrace();
}
return null;
}
public void detectIntentStream(String projectId, String audioFilePath, String sessionId,
String languageCode) throws Throwable {
// Start bi-directional StreamingDetectIntent stream.
final CountDownLatch notification = new CountDownLatch(1);
final List<Throwable> responseThrowables = new ArrayList<>();
final List<StreamingDetectIntentResponse> responses = new ArrayList<>();
// Instantiates a client
try (SessionsClient sessionsClient = SessionsClient.create()) { // on this line it throws exception to me
// Set the session name using the sessionId (UUID) and projectID (my-project-id)
SessionName session = SessionName.of(projectId, sessionId);
System.out.println("Session Path: " + session.toString());
// Note: hard coding audioEncoding and sampleRateHertz for simplicity.
// Audio encoding of the audio content sent in the query request.
AudioEncoding audioEncoding = AudioEncoding.AUDIO_ENCODING_LINEAR_16;
int sampleRateHertz = 16000;
// Instructs the speech recognizer how to process the audio content.
InputAudioConfig inputAudioConfig = InputAudioConfig.newBuilder()
.setAudioEncoding(audioEncoding) // audioEncoding = AudioEncoding.AUDIO_ENCODING_LINEAR_16
.setLanguageCode(languageCode) // languageCode = "en-US"
.setSampleRateHertz(sampleRateHertz) // sampleRateHertz = 16000
.build();
ApiStreamObserver<StreamingDetectIntentResponse> responseObserver =
new ApiStreamObserver<StreamingDetectIntentResponse>() {
@Override
public void onNext(StreamingDetectIntentResponse response) {
// Do something when receive a response
responses.add(response);
}
@Override
public void onError(Throwable t) {
// Add error-handling
responseThrowables.add(t);
}
@Override
public void onCompleted() {
// Do something when complete.
notification.countDown();
}
};
// Performs the streaming detect intent callable request
ApiStreamObserver<StreamingDetectIntentRequest> requestObserver =
sessionsClient.streamingDetectIntentCallable().bidiStreamingCall(responseObserver);
// Build the query with the InputAudioConfig
QueryInput queryInput = QueryInput.newBuilder().setAudioConfig(inputAudioConfig).build();
try (FileInputStream audioStream = new FileInputStream(audioFilePath)) {
// The first request contains the configuration
StreamingDetectIntentRequest request = StreamingDetectIntentRequest.newBuilder()
.setSession(session.toString())
.setQueryInput(queryInput)
.build();
// Make the first request
requestObserver.onNext(request);
// Following messages: audio chunks. We just read the file in fixed-size chunks. In reality
// you would split the user input by time.
byte[] buffer = new byte[4096];
int bytes;
while ((bytes = audioStream.read(buffer)) != -1) {
requestObserver.onNext(
StreamingDetectIntentRequest.newBuilder()
.setInputAudio(ByteString.copyFrom(buffer, 0, bytes))
.build());
}
} catch (RuntimeException e) {
// Cancel stream.
requestObserver.onError(e);
}
// Half-close the stream.
requestObserver.onCompleted();
// Wait for the final response (without explicit timeout).
notification.await();
// Process errors/responses.
if (!responseThrowables.isEmpty()) {
throw responseThrowables.get(0);
}
if (responses.isEmpty()) {
throw new RuntimeException("No response from Dialogflow.");
}
for (StreamingDetectIntentResponse response : responses) {
if (response.hasRecognitionResult()) {
System.out.format(
"Intermediate transcript: '%s'\n", response.getRecognitionResult().getTranscript());
}
}
// Display the last query result
QueryResult queryResult = responses.get(responses.size() - 1).getQueryResult();
System.out.println("====================");
System.out.format("Query Text: '%s'\n", queryResult.getQueryText());
System.out.format("Detected Intent: %s (confidence: %f)\n",
queryResult.getIntent().getDisplayName(), queryResult.getIntentDetectionConfidence());
System.out.format("Fulfillment Text: '%s'\n", queryResult.getFulfillmentText());
textView.setText(queryResult.getQueryText() + queryResult.getFulfillmentText());
}
}
}
当我运行我的代码时，我得到了以下异常

我不知道我做错了什么。我如何在Android中使用此库。在Google Dialogflow library示例中给出了java，我们必须在环境变量中设置 Google_Application_credential 。因此，我在Android中实现我使用下面的代码。
GoogleCredentials credentials = GoogleCredentials.fromStream(getResources().getAssets().open("Modroid-Test-9d8a744b520a.json"))
.createScoped(newArrayList("https://www.googleapis.com/auth/compute"));
credentials.toBuilder().build();
但它并没有起作用，并且在
上给了我一个例外 try (SessionsClient sessionsClient = SessionsClient.create())
答案 0 :(得分：1)
result = pd.merge(df1, df2, left_on='name', right_on='account', how='left', sort=False)
答案 1 :(得分：0)
texts.add("Hi");
String sessionId="3f46dfa4-5204-84f3-1488-5556f3d6b8a1";
String languageCode="en-US";
GoogleCredentials credentials = GoogleCredentials.fromStream(new FileInputStream("E:\\GoogleDialogFlow\\ChatBox\\Json.json"))
.createScoped(Lists.newArrayList("https://www.googleapis.com/auth/cloud-platform"));
SessionsSettings.Builder settingsBuilder = SessionsSettings.newBuilder();
SessionsSettings sessionsSettings = settingsBuilder.setCredentialsProvider(FixedCredentialsProvider.create(credentials)).build();
SessionsClient sessionsClient = SessionsClient.create(sessionsSettings);
SessionName session = SessionName.of(projectId, sessionId);
com.google.cloud.dialogflow.v2.TextInput.Builder textInput = TextInput.newBuilder().setText("Hi").setLanguageCode(languageCode);
QueryInput queryInput = QueryInput.newBuilder().setText(textInput).build();
DetectIntentResponse response = sessionsClient.detectIntent(session, queryInput);
QueryResult queryResult = response.getQueryResult();
System.out.println("====================");
System.out.format("Query Text: '%s'\n", queryResult.getQueryText());
System.out.format("Detected Intent: %s (confidence: %f)\n",
queryResult.getIntent().getDisplayName(), queryResult.getIntentDetectionConfidence());
System.out.format("Fulfillment Text: '%s'\n", queryResult.getFulfillmentText());
credentials.toBuilder().build();```
This source code is working on my window but when I am publishing it getting error on Linux server.So time they are saying update your guava-23.6 jar file but problem is still there.
I am trying read my .json file from one path. I am not setting the environment variable on Linux , even my local machine.
