My function below includes a cURL call which throws a text string at a Google Cloud text analysis API, returning a response object, which we then parse to get a specific piece.
It has been recommended to me that I switch the cURL PHP statement to use WordPress' wp_remote_get.
I have read the docs for that but, to be honest, I don't understand how my cURL header fields should map to wp_remote_get arguments. Or even if it should be wp_remote_post rather than wp_remote_get.
How can I try and understand what to do here?
function get_entity_type(
$text_to_analyse, // passed string to be handed to GCloud NLP
$entity = 'type' // part of each "entities" result to return
) {
// Google Cloud API key
$options = get_option( 'cxt_settings' );
$google_nlp_api = $options['cxt_gcloud'];
// Supply data payload in JSON format
$data = '{
"document":{
"type":"PLAIN_TEXT",
"content":"'.$text_to_analyse.'"
},
"encodingType":"UTF8"
}';
$payload = $data;
// Call the API endpoint, with API key
$url = ':analyzeEntities?key='.$google_nlp_api;
// Prepare to get results using cURL
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
// Set HTTP Header for POST request
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($payload))
);
// Submit the POST request
$result = curl_exec($ch);
// Store result in array
$arr = json_decode($result, true);
// Close cURL session handle
curl_close($ch);
// Pluck out the first value from the response object
$ent_val = $arr['entities'][0][$entity];
return $ent_val;
// List of possible entities:
// UNKNOWN
// PERSON
// LOCATION
// ORGANIZATION
// EVENT
// WORK_OF_ART
// CONSUMER_GOOD
// OTHER

- Have you seen this resource? It talks about how you can send the headers. developer.wordpress.org/plugins/http-api/… – Nick Young Commented Sep 27, 2019 at 22:55

Why do you do this?
WordPress created by php and curl works fine in WordPress. Curl is very powerful and has more options
