贴一段python的代码 希望兄弟们别踩坑

php post 提交需要中文不转码：json_encode($data, JSON_UNESCAPED_UNICODE)

function curl_post($url, $data) {
      $data = json_encode($data, JSON_UNESCAPED_UNICODE);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
		'Content-Type: application/json;charset=UTF-8;'
		)
    );
    $handles = curl_exec($ch);
    curl_close($ch);
    return json_decode($handles, true);
}
