API之要求接口上传pdf以合同PDF的二进制数据，multpart方式上传

实现

//时间戳13位毫秒 private function getMillisecond() { list($s1,$s2) = explode(' ',microtime()); return (float)sprintf('%.0f',(floatval($s1) + floatval($s2)) * 1000); } // 组装参数 private function gysscPost1($url,$data) { // $data['timestamp'] = '1694402111964'; $data['timestamp'] = $this->getMillisecond(); $data['v'] = '1.0'; $data['appKey'] = $this->appKey; $data['method'] = $data['method']; $data['token'] = $this->token; $data['format'] = 'json'; $data['paramType'] = 'json'; $contractBytes = $data['contractBytes']; // 上传pdf的文件地址 unset($data['contractBytes']); ksort($data); $data['sign'] = $sign_str; $res = $this->curl1('http://39.101.164.226:8073/openapi', $data,$contractBytes); $result = $this->decrypt($res); //解密 return $result; } public function curl1($url, $post,$contractBytes,$is_json = false,$aHeader='') { $ch = curl_init(); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_SAFE_UPLOAD, true); curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); curl_setopt($ch, CURLOPT_URL, $url); // 重点是下面 传参 $post['contractBytes']= curl_file_create($contractBytes, mime_content_type($contractBytes), time() .
