问题描述：
    php文件中，通过curl，header头，body参数，验证通过后，接收对方的数据。传参有两种方式。

解决办法：

function post_http($array='',$url){ 

  $ch = curl_init(); 
  $header = array('Content-Type: application/json; charset=utf-8','Accept: application/json','secretKey:xxxxxxxx','signKey:xxxxxxxxxxx12'); 

  curl_setopt($ch, CURLOPT_URL, $url); 
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'POST'); 
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

  //https  //curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 2); 
  //curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
  // post数据 
  curl_setopt($ch, CURLOPT_POST, 1); 

  // post设置头 
  // curl_setopt($ch, CURLOPT_PROXY, '127.0.0.1:8080');//设置代理服务器 

 //启用时会将头文件的信息作为数据流输出
  curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
  // post的变量
  $arr = json_encode($array);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $arr); 
  curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
  $result = curl_exec($ch); 
  if (curl_errno($ch)) { 
    return curl_error($ch); 

  }
  curl_close($ch); 
  //打印获得的数据 
  return json_decode($result,true); 

}

function post_http($url){
  $body = "key=val&key1=val2";

  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_POST,true);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

  curl_setopt($ch, CURLOPT_POSTFIELDS, $body);

  curl_setopt($ch, CURLOPT_TIMEOUT, 30);
  $result = curl_exec($ch);
  if (curl_errno($ch)) {
    return curl_error($ch);

 }
  if (!curl_errno($curl)) {
  echo json_encode(['code'=>1001,'msg'=>'网络或者URL出错！','data'=>curl_errno($curl)]); exit();
  }
    //关闭cURL资源，并且释放系统资源   
    curl_close($ch);
    //打印获得的数据
    return json_decode($result,true);
}
