Dialogflow V2 API - 如何传递上下文 and/or 有效负载 [PHP]

Question

我正在尝试将上下文和有效负载发送到 Dialogflow V2 API。我能够成功发送一个 queryString 并从我的代理那里得到响应。但是，我需要通过此查询传递上下文和有效负载参数，而且我似乎无法找到 PHP 的任何帮助。请在下面查看我的代码。我能够创建上下文对象和有效负载对象（至少我认为它已创建），但如何将其传递给 API？

任何帮助将不胜感激，因为我是 dialogflow 的新手并且已经为此苦苦挣扎了几天。

function detect_intent_texts($projectId, $text, $sessionId, $context, $parameters, $languageCode = 'en-US') {
    // new session
    $test = array('credentials' => 'client-secret.json');
    $sessionsClient = new SessionsClient($test);
    $session = $sessionsClient->sessionName($projectId, $sessionId ?: uniqid());
    //printf('Session path: %s' . PHP_EOL, $session);

    // create text input
    $textInput = new TextInput();
    $textInput->setText($text);
    $textInput->setLanguageCode($languageCode);

    $contextStruct = new Struct();
    $contextStruct->setFields($context['parameters']);
    $paramStruct = new Struct();
    $paramStruct->setFields($parameters['parameters']);

    $contextInput = new Context();
    $contextInput->setLifespanCount($context['lifespan']);
    $contextInput->setName($context['name']);
    $contextInput->setParameters($contextStruct);

    $queryParams = new QueryParameters();
    $queryParams->setPayload($paramStruct);

    // create query input
    $queryInput = new QueryInput();
    $queryInput->setText($textInput);

    // get response and relevant info
    $response = $sessionsClient->detectIntent($session, $queryInput); // Here I don't know how to send the context and payload
    $responseId = $response->getResponseId();
    $queryResult = $response->getQueryResult();
    $queryText = $queryResult->getQueryText();
    $intent = $queryResult->getIntent();
    $displayName = $intent->getDisplayName();
    $confidence = $queryResult->getIntentDetectionConfidence();
    $fulfilmentText = $queryResult->getFulfillmentText();

    $returnResponse = array(
        'responseId' => $responseId,
        'fulfillmentText' => $fulfilmentText
    );

    $sessionsClient->close();

    return $returnResponse;
}

恰巧，当我 post 我的问题时，我得到了结果。

多亏了这个postHow to set query parameters dialogflow php sdk.

我在我的代码中添加了以下内容并且它起作用了。

已添加

$optionalsParams = ['queryParams' => $queryParams];

已更改

$response = $sessionsClient->detectIntent($session, $queryInput, $optionalsParams);
