$data = array("name" => "Hagrid", "age" => "36");
$data_string = json_encode($data); $ch = curl_init('http://api.local/rest/users');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS,$data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
); $result = curl_exec($ch);
curl_close($ch);
接收端使用 $GLOBALS['HTTP_RAW_POST_DATA']
或者
$postdata = file_get_contents("php://input");
