Usage

To use DialogFlow you will to set up an account and download the JSON file that contains the private access key. You can then include the JSON file with your project and load the credentials.

try (InputStream input = DialogFlowIntentDetectorIT.class.getResourceAsStream("/credentials.json")) {
    String projectId = "YOUR_DIALOG_FLOW_PROJECT_ID"
    GoogleCredentials credentials = GoogleCredentials.fromStream(input)
                    .createScoped(Lists.newArrayList("https://www.googleapis.com/auth/cloud-platform"));
    DialogFlowIntentDetector instance = new DialogFlowIntentDetector(credentials, projectId);
} catch (IOException ex) {
    ...
}

Testing

To run the integration tests you will need to have an configured agent with DialogFlow and API access credentials as a JSON file.

Update the integration-test.properties to match your project id and the name of the file containing the credentials.

projectId=conversation-kit-test-agent-gs
credentialsFile=/dialogflow-it.json

Then run

mvn integration-test
