PHP怎么发送json类型的CURL请求？

use linslin\yii2\curl\Curl;



$curl = new Curl();

$paramsTo = array(

'data' =>array(

'name' => $name

),

);

$curl->setOption(CURLOPT_HTTPHEADER, array('Content-Type:application/json','Accept:application/json'));

$curl->setOption(CURLOPT_POSTFIELDS, json_encode($paramsTo));

$return_result = $curl->post($url);

$return_result = json_decode($return_result,true);
