PHP调用拼多多API模板

拼多多的 API 模板就更简单了，前段时间刚放出来接口权限，上周开始对接完成。
都是无需授权的接口，所以也就不需要刷新 token 之类的事。
另外拼多多的 token 过期时间是 30 天，每次都要重新获取 accesstoken，麻烦。

/*拼多多API类*/
class PDDApi
{
private $client_id = 'client_id';    //  你的client_id
private $client_secret = 'client_secret';   //  你的client_secret
private function GetPDDApi($apiType, $param)
{
$appInfo = zfun::f_getset('pdd_client_id,pdd_client_secret');
$param['client_id'] = $this->client_id;
$param['type'] = $apiType;
$param['data_type'] = 'JSON';
$param['timestamp'] = self::getMillisecond();
ksort($param);    //  排序
$str = '';      //  拼接的字符串
foreach ($param as $k => $v) $str .= $k . $v;
$sign = strtoupper(md5($this->client_secret. $str . $this->client_secret));    //  生成签名    MD5加密转大写
$param['sign'] = $sign;
$url = 'http://gw-api.pinduoduo.com/api/router';
return self::curl_post($url, $param);
}

//  post请求
private static function curl_post($url, $curlPost)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);

return $result;
}

//  获取13位时间戳
private static function getMillisecond()
{
list($t1, $t2) = explode(' ', microtime());
return sprintf('%.0f', (floatval($t1) + floatval($t2)) * 1000);
}
