How to set output contexts while creating a intent in dialogflow PHP? - dialogflow-es

Question

I am trying to set output context to a particular intent via v2 create intent API.
Please check my code.
use Google\Cloud\Dialogflow\V2\SessionsClient;
use Google\Cloud\Dialogflow\V2\TextInput;
use Google\Cloud\Dialogflow\V2\QueryInput;
use Google\Cloud\Dialogflow\V2\IntentsClient;
use Google\Cloud\Dialogflow\V2\Intent_TrainingPhrase_Part;
use Google\Cloud\Dialogflow\V2\Intent_TrainingPhrase;
use Google\Cloud\Dialogflow\V2\Intent_Message_Text;
use Google\Cloud\Dialogflow\V2\Intent_Message;
use Google\Cloud\Dialogflow\V2\Intent;
use Google\Cloud\Dialogflow\V2\Context;
use Google\Cloud\Dialogflow\V2\ContextsClient;
private function intent_create(){
putenv('GOOGLE_APPLICATION_CREDENTIALS='.getcwd() . '/strive_stage.json');
$intentsClient = new IntentsClient();
/** Create Intent **/
$disaplayName = "Where is Goa";
$utterances = ["Goa", "Where is Goa"];
// prepare training phrases for intent
$trainingPhrases = [];
foreach ($utterances as $trainingPhrasePart) {
$part = new Intent_TrainingPhrase_Part();
$part->setText($trainingPhrasePart);
// create new training phrase for each provided part
$trainingPhrase = new Intent_TrainingPhrase();
$trainingPhrase->setParts([$part]);
$trainingPhrases[] = $trainingPhrase;
}
$messageTexts = 'Goa is in India.';
// prepare messages for intent
$text = new Intent_Message_Text();
$text->setText([$messageTexts]);
$message = new Intent_Message();
$message->setText($text);
$createIntentObject = $intentsClient->projectAgentName(env("DIALOG_FLOW_PROJECT_ID"));
// prepare intent
$intent = new Intent();
$intent->setDisplayName($disaplayName);
$intent->setTrainingPhrases($trainingPhrases);
$intent->setMessages([$message]);
$contexts = ['test'];
foreach($contexts as $con){
$contextObj = new Context();
$contextObj->setName($con);
$contextData[] = $contextObj;
$intent->setOutputContexts($contextData);
}
// $intent->getOutputContexts('test');
//dd($intent);
$response = $intentsClient->createIntent($createIntentObject, $intent);
printf('Intent created: %s' . PHP_EOL, $response->getName());
}
I am getting error message
{
"message": "com.google.apps.framework.request.BadRequestException: Resource name does not match format 'projects/{project_id}/agent/sessions/{session_id}/contexts/{context_id}' or 'projects/{project_id}/locations/{location_id}/agent/sessions/{session_id}/contexts/{context_id}'.",
"code": 3,
"status": "INVALID_ARGUMENT",
"details": []
}
I believe the issue is with the format of storing the output context. Please help me on this.

Answer 1

I had the same issue. The answer is to not put in the bare name, but to have a string of a certain format made
see http://googleapis.github.io/google-cloud-php/#/docs/google-cloud/v0.131.0/dialogflow/v2/intent?method=setOutputContexts
// $projectId your project id
// $sessionId can be anything, I use $sessionId = uniqid();
$uri = "projects/$projectId/agent/sessions/$sessionId/contexts/$con";
$contextObj->setName($uri);

I can see that there are any response about this topic.
I leave here my solution for the next generations
To create a output context you need to create the correct format, for this objetive you can use Context class Google\Cloud\Dialogflow\V2\Context
private function parseoOutputContexts($contexts, $project_id, $lifespan = 5)
{
$newContexts = array();
foreach ($contexts as $context) {
$newContexts[] = new Context(
[
'name' => 'projects/' . $project_id . '/agent/sessions/-/contexts/' . $context,
'lifespan_count' => $lifespan
]
);
}
return $newContexts;
}
And you can use this function to finnaly add the output context to the object Intent.
$dialogflow_intent = new Intent();
$output_contexts = ['output_context_1'. 'output_context_2'];
$output_contexts = $this->parseOutputContexts($output_contexts, '[YOUR_PROJECT_ID]');
$dialogflow_intent->setOutputContexts($output_contexts);
