PHP基于curl模拟post提交json数据示例

"test001",
  "pass"=>"xxxx",
);
$data = json_encode($param);
list($return_code, $return_content) = http_post_data($url, $data);//return_code是http状态码
print_r($return_content);exit;
function http_post_data($url, $data_string) {
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
  curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    "Content-Type: application/json; charset=utf-8",
    "Content-Length: " . strlen($data_string))
  );
  ob_start();
  curl_exec($ch);
  $return_content = ob_get_contents();
  ob_end_clean();
  $return_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  return array($return_code, $return_content);
}
