如何POST一个JSON格式的数据给Restful服务

PHP用cUrl实现：

$data = array("name" => "Hagrid", "age" => "36");
$data_string = json_encode($data);
$ch = curl_init('');
curl_setopt($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);
