先日cURLで書かれていたコードをwp_remote_postに変更したのでメモ。

cURL

$params = [
	'xxx' => 'aaa'
	'yyy' => 'bbb',
	'zzz' => 'ccc',
];
$headers = [
	'contentType: application/json; charset=utf-8'
];

$curl = curl_init();
curl_setopt( $curl, CURLOPT_CUSTOMREQUEST, 'POST' );
curl_setopt( $curl, CURLOPT_URL, 'https://xxxxxxxxx.com/' );
curl_setopt( $curl, CURLOPT_POSTFIELDS, json_encode( $params ) );
curl_setopt( $curl, CURLOPT_HTTPHEADER, $headers );
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, true );
$response = curl_exec( $curl );
curl_close( $curl );

$result = json_decode( $response, true );

wp_remote_post

$params = [
	'xxx' => 'aaa'
	'yyy' => 'bbb',
	'zzz' => 'ccc',
];

$data = wp_remote_post('https://xxxxxxxxx.com/', array(
	'method' => 'POST',
	'headers' => array(
		'content-Type' => 'application/json; charset=utf-8'
	),
	'httpversion' => '1.0',
	'sslverify' => false,
	'body' => json_encode($params)
));

if( is_wp_error( $data ) ) {
	return false;
}

$response = wp_remote_retrieve_body( $data );


$result = json_decode( $response, true );
