Analysis of parameter passing issues when using curl to send get requests in PHP

get request is the simplest request, but you should pay attention to whether your request is an http request or an https request, because SSL verification must be turned off when making an https request, otherwise the verification will not pass and there is no way. Data is requested.

Parameters of GET request

Get passes parameters in the same way as normal request url passes parameters

function get_info($card){
 
  $url ="http://www.sdt.com/api/White/CardInfo?cardNo=".$bank_card; 
 
  $ch = curl_init();
  //设置选项，包括URL
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HEADER, 0);
 
  //执行并获取HTML文档内容
  $output = curl_exec($ch);
  //释放curl句柄
  curl_close($ch);
  return $output;
}

Pay attention to SSL verification when making HTTPS requests

function get_bankcard_info($bank_card){
 
  $url ="https://ccdcapi.alipay.com/validateAndCacheCardInfo.json?_input_charset=utf-8&cardNo=".$bank_card."&cardBinCheck=true";
 
  $ch = curl_init();
 
  //设置选项，包括URL
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);//绕过ssl验证
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
 
  //执行并获取HTML文档内容
  $output = curl_exec($ch);
 
  //释放curl句柄
  curl_close($ch);
  return $output;
}
