php中使用curl发送JSON数据
在PHP中,可以使用curl去发送JSON数据,例子如下:

$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);
