Using php, how can I fetch specific data from dialogflow fulfillment JSON request and store the data into a php variable?
Here is the JSON response I 'm getting from my dialogflow agent
{
"responseId": "e9106589-2a41-47c4-bdde-8f3cee8f40da",
"queryResult": {
"queryText": "switch on cfl",
"action": "input.switchoncfl",
"parameters": {
"makeRequest": "cfl_on"
},
"allRequiredParamsPresent": true,
"fulfillmentMessages": [
{
"platform": "ACTIONS_ON_GOOGLE",
"simpleResponses": {
"simpleResponses": [
{
"textToSpeech": "Sure. Turning CFL on... Anything else can I help you with?",
"displayText": "Sure. Turning CFL on..."
}
]
}
}
],
"intent": {
"name": "projects/smarthome-cf277/agent/intents/5be27f38-105d-4854-b62d-ec3a6de80cc7",
"displayName": "1.1-Switch_on_CFL"
},
"intentDetectionConfidence": 1,
"languageCode": "en"
},
"originalDetectIntentRequest": {
"payload": {}
},
"session": "projects/smarthome-cf277/agent/sessions/ca0261aa-913f-96f1-b5aa-7755637d5ab7"
}
And here is my php code
<?php
header("Content-Type: application/json");
ob_start();
$content = json_decode(file_get_contents('php://input'),true);
$action = $content['parameters']['makeRequest'];
ob_end_clean();
?>
I want to store cfl_on value to $action variable. How can I do that? this php code does not work.
You just missed out the "queryResult" layer of the object.
